IntRoDUctIon

Washing and everything related to washing has developed significantly since the beginning of history. Nowadays
people are using laundry detergents, synthetic detergents, washing machines, dryers and there are plants to treat
the wastewater of washing. While in the prehistory people used to have only water and used rivers and streams
as water supply, defecated in nature and their wastes had a low impact on the environment. Even though all these
developments seem very familiar and normal to us nowadays, you may have asked this already to yourself: “How did
we come to this level in washing?”

The answer to this question is a long and interesting story, the “History of Washing”, starting from prehistory till the
21st century.

PReHIStoRY (100,000 – 30,000 B.c.)

Prehistory covers the 2.5 million years of man’s existence before the advent of written records. How early man lived
during this period is determined largely through archaeological evidence.

Soap
If prehistoric man cleaned himself or his clothing, he used water only.

Baths
Prehistoric people may have learned from experience that eating with dirty hands could be dangerous and often
fatal. This may have led them to wash their dirty hands in water, providing the first example of washing having
an impact on human health. With the discovery of fire about 1.8 million years ago, it’s possible that water was
heated for washing.

Water supply
Early man lived near rivers and streams, and used the water for drinking.

Human waste
People  living  in  small  societies,  such  as  families  or  small  tribes,
usually  defecated  privately  near  a  stream  or  somewhere  far
enough away from where they lived that the smell wouldn’t
bother  them.  When  it  came  to  Neanderthal  man,  this
often  took  place  deep  inside  a  cave.  This  became  a
health  problem  once  populations  grew  and  some
cultures became sedentary.

Environmental impact
Since prehistoric man lived in a small group or
community, and was primarily concerned with
activities  needed  for  survival  (hunting  and
gathering  food),  the  environmental  impact
of human activity was small and, in a sense,
hardly  different  from  the  impact  of  groups
of animals. Any wastes that were generated
would  be  degraded  quickly.  The  human
population density was far below the carrying
capacity of the environment.

AncIent tIMeS (2500 B.c. – 476 A.D. approx. 3000 years)

In ancient times, bathing and clothes washing evolved. Soap began to be used, both for bathing

and for laundering clothes. The Romans used public laundries or “fulleries”, staffed by workers who

washed clothing with a version of detergents. The fulleries were not a healthy environment for those

who worked in them. Public baths became popular, as bathing was seen as a social event. Aqueducts

brought water into the homes of the wealthy, whereas the working class relied on hand-carrying

water from the public fountains and rivers to their homes. Plumbing was still rudimentary, with

waste carried through open drains to rivers. Because of the lack of waste treatment of any kind, the

environmental impact of human activity was high, especially near the cities.

Romans were a fashion-conscious people and paid much attention to their attire.

Soap

The first primitive soap was made from ashes from wood and other

plants, by extraction with water. Ashes from halophytes – plants

from the Mediterranean region - such Saponaria sp., Salicornia

sp. and Salsola sp., were particularly effective for soap-

making. The fact that such alkaline solutions had cleaning

properties was probably discovered accidentally.

According to legend, the word soap, or rather the

process of saponification, derives from Sapo Hill in

Rome, where animals were sacrificed and cremated.

Tallow, or animal fat, and ash were washed down

the hill by rainwater, into the clay soil along the

Tiber River. Women found that washing clothes

was easier if they used this clay. A less romantic
derivation is the name of the Italian town of Savona,

where large quantities of soap were manufactured

during the 9th century A.D. In French, “savon”

means soap. The oldest reference to purposeful

soap-making dates back to 2800 B.C. Fats were

boiled with ashes to make soap. Gallic and Germanic

tribes carried out saponification by trial and error. In

the process of soap-making, they also produced glycerol

as a result of the action of alkali on fat (goat tallow, birch

wood ash and herbal extract colouring). Human or animal

urine was commonly used as a cleaning agent in ancient times.

Its cleaning properties are due to the production of the alkaline

ammonium carbonate from fermentation of urea. Its use was first

reported in the Orient, from which it spread to the West.

Baths
The first Roman baths were built around 312 B.C. and continued to be popular until the fall of the Roman Empire
in the 6th century. At the end of the day, Roman men and women would gather at the public bathhouses. Some
wealthy families had their own bathhouses, yet they would often invite friends to bathe with them, as bathing was
very much a social event. Afterwards, they would spend the rest of the evening on an elaborate dinner. When
the Roman Empire fell in 467 A.D., their habits with regards to personal cleanliness were also lost. In the Middle
Ages, this lack of hygiene would have dramatic consequences. The ancient Greeks “washed” themselves with
lumps of clay, had steam baths and rubbed their skin with oil, such as olive oil, which they then scraped off with
an instrument called a “strigil”, along with any dirt. The use of soap for bathing was reported as early as 1500 B.C.
by the ancient Egyptians.

Laundry
Frescoes in Pompeii show how important laundry was for the Romans. Laundry was not done at home, at least not
by the wealthier Romans. It was done at the public “fulleries” – the equivalent of the modern laundromat – by

workers called “fullones.” “The large fulleries have several features in common. They contain a large hall with very
large basins in the floor, communicating with one another. In these basins clothes were put to soak and cleaned.
Along three sides of the hall are pressing-bowls, usually made of terracotta, often the lower half of a dolium.
Here the material was further cleaned, by workers who ’jumped‘ or ’danced‘ on the clothes (the so-called saltus
fullonicus; Seneca, Epistulae 15,4), while they leaned on small walls on either side. Detergents were used, such as
the creta fullonica (fuller’s earth), that was stored in small bowls. It helped remove the grease and enhanced the
colours. Urine, collected in public urinals, was used for bleaching, and so was sulphur, which was burned under
wooden frames over which the cloth was suspended. After the pressing, the material was taken to the basins again,
for the removal of the detergents. Fullers were organized into powerful Guilds. Clothes were cleaned by treading
(fulling) in stone bowls containing clay and ammoniated water. After rinsing once, the bowls were filled once
more and the clothes were rinsed again. Drying took place on bell-shaped wire frames under which sulphur was
burned.” (from the Ostia Anctica web site). The Roman laundries were not a healthy work environment: workers
were constantly exposed to polluted, foul-smelling air and their skin was in constant contact with chemicals in the
water. As a result they ran a high risk of developing work-related illnesses. The ancient Greeks used only water,
without soap, for laundry.

Water supply
During the early years, water for Rome was brought in from the Tiber River. Aqueducts that piped the water from
rivers or wells into the city were built during the Late Empire. Wealthy Romans had the water piped all the way into
their homes, but most people had to rely on the public fountains or water delivery by a contractor or Aquarius.
Some homes had cisterns in which rainwater was collected. The aqueducts and cisterns of Carthage (Tunisia, N.
Africa) are well preserved to this day.

Plumbing
Rome was well equipped with open drains and sewers, which ran parallel to streets. Many houses had latrines,
but apartments did not. Where there were no latrines, chamber pots were used. These were emptied in the
public drains and sewers, or in public urinal pots. The large public urinal pots at the street corners were
periodically emptied by “fullers” who worked in the laundry facilities, where urine was used as a laundry
additive. Public toilets were large, rectangular rooms that could be used by many people at the same time.
The construction was similar to today’s “outhouses,” but the waste was continuously flushed away by
running water in the sewers down below.

Environmental impact
Wastewater from households as well as from public toilets was flushed away to the rivers, often via open
channels that ran alongside or in the middle of the streets. Out of necessity, ancient civilizations were
much more tolerant of foul odors than modern society! As these sewage streams and human waste
streams were discharged to the rivers without any form of treatment, the environmental impact of
human activity was high. Similar situations still exist to this day, in developing nations. A well known
example is that of the sacred Ganges River in India, used by millions for bathing and washing but also
the receptacle for untreated sewage and human waste from the cities.

Fabrics
Men and women of Rome were very interested in fashion. They wore tunics, which were knee-length
for the men and floor-length for the women. Heavy white togas were worn on formal occasions. The
fabrics of the time were wool, linen, silk and cotton. The women wore make-up and jewelry, mostly
gold and precious stones among higher classes, amber jewelry among lower classes.

MIDDLe AGeS (476 A.D. – 1453 A.D. approx. 1000 years)

During the Middle Ages (about A.D. 476 to A.D. 1453) people in Europe became much less concerned

with hygiene, and public health declined. People began to have a superstitious fear of water, believing

it to cause disease, so bathing was no longer a daily activity. In its place, people prayed and made

pilgrimages, believing that sin was another major cause of disease. Clothing was washed only every few

months. Towns became overcrowded. Household wastewater and the contents of chamber pots were

tossed into the streets. This lack of personal cleanliness and the unsanitary living conditions - especially

the lack of any type of waste treatment - had dire consequences. Epidemics swept through Europe. The

Black Plague of the 14th century killed tens of millions of people.

Soap

In the Middle Ages, soap was used primarily for washing clothes.

Arab traders brought bars of soap to Europe in the 7th century,

and soon soapmaking became an established craft in Europe.

Soapmakers formed guilds and jealously guarded their recipes.

Soap production began to differ from region to region. In

southern European countries, such as Italy, Spain, and

southern France, soap was made from olive oil. During

this period, Castile soap began to be made in Spain.

In the countries of northern Europe, soap was made

from a base of animal fats, primarily tallow from

cattle, and sometimes even from fish oils. Aromatic

herbs were added for fragrance. The soaps made

from olive oil were of a higher quality than those
made from animal fats, and soap manufacturers in

the south began to export their products to other

countries. In the 9th century, Marseilles, Geneva,

Savona, and Venice became important centres of

soap manufacturing. These regions had a plentiful

supply of olive oil and the barilla plant, the ashes of

which were used to make lye. During the 10th century,

soap production expanded to many European cities. By

the 12th century, soap started to be produced in England

where the soap business was very successful and would

remain so for centuries to come. In 1622, King James I granted

a monopoly to a soapmaker for $100,000 a year! Until the 19th

century, soap was a heavily taxed luxury item in most countries, and

therefore out of reach for the ordinary citizen.

Baths
In Europe, cities had public baths, called stews, where two or three patrons at a time bathed together in large wooden
tubs. The aristocracy had their own private baths, and even tiled rooms devoted to bathing. But early in the Middle
Ages, the practice of bathing declined, as people began to believe that it spread epidemics. But because people also
believed that bad odors spread disease, they made liberal use of perfume.

Laundry
Clothing was washed only every two or three months. It was soaked in a tub with a washing solution of lye and fuller’s
earth or white clay. Then it was trampled or beaten, after which the dirty wash water ran out through a hole. This
process was repeated until the water came out clean, after which the clothes were rinsed, wrung out by hand, and
left to air dry.

Water supply
Wealthier citizens and the aristocracy had water piped into their homes or castles, and peasants used public fountains
or wells. Because of nonexistent sanitation, drinking water was often contaminated.
Wastewater was discarded directly into the streets.

Human waste
Chamber pots were used to contain human waste, and the contents were emptied into the streets. Some cities had
laws requiring people to call out a warning before emptying pots, to avoid unpleasant accidents. In many homes, the
first floor had a protuberance in the back, and feces were collected from there.

Environmental impact
Especially in cities, the environmental impact of human activity was very high. Waste was discarded into the streets,
where is sat for days before it was washed untreated into rivers and streams.

Fashion
Most people in the Middle Ages wore woolen clothing over undergarments made of linen. The wealthy wore garments
with brighter colors, made from better materials. Toward the end of the Middle Ages, clothing became more elaborate.
Wealthy men wore hose and a jacket, often with skirting, and aristocratic women were partial to flowing gowns and
headdresses shaped like hearts or butterflies or tall steeple caps.

RenAISSAnce (approx. 1450 A.D. – 1700 A.D. ; approx. 200 years)

The Renaissance - the period between about 1450 and 1700 - was a time of renewed flourishing of the arts and
the intellect in Europe. In the beginning of this period, though, hygiene remained firmly in the Dark Ages. People
continued to fear water, believing that it would dilate the skin’s pores and expose the organs to the dreaded plague.
But as the Renaissance progressed, the nobility’s desire to maintain its appearance as a higher breed brought more
emphasis to personal hygiene. Fashion, and changing into clean clothes frequently, represented symbols of status
to the wealthy. Science also advanced, and doctors began to understand that lack of hygiene was a factor in the
spread of contagious diseases, and some doctors even advocated a regular bath! Cleanliness campaigns and
a more widespread use of soap resulted. During the Renaissance, soap became more refined, and doing the
laundry remained a highly ritualized, time-consuming process. Although water closets had been invented, this
marvel of plumbing would not become a fixture in most homes until much later, around the middle of the
19th century, for lack of adequate water supply and sewer systems.

Soap
Soap making became more specialized. In the 15th and 16th
centuries in France, soap was made on a small scale from
goat tallow and beech ash, but in the 17th century, soap
factories were established. The first one, built by royal
edict  in  Toulon,  was  an  immediate  success.  More
factories were built in Marseilles. By the end of the
century,  Marseilles  had  to  import  raw  materials
from all over the Mediterranean to keep up with
demand,  and  the  French  perfected  the  soap
manufacturing process, now using vegetable oils
rather than animal fat. All along, soap was used
for laundry. Towards the end of the Renaissance,
soap came back into favor for bathing, and people
began to use soap for shaving and shampooing.

Baths
Throughout much of the Renaissance, people believed
that water penetrated the skin and spread disease.
Indeed, King Louis XIII had what was only his second
bath at the age of 7, and Louis XIV took baths only when
it was prescribed as a medical treatment. It was thought that
a layer of dirt protected the body, so people cleaned themselves

by rubbing exposed parts of the body with a dry, sometimes perfumed, cloth. To show that they were “clean,”

the nobility wore white linen shirts, and changed them daily. In 1626, Savot, a French etiquette writer, wrote,

“We can more easily do without [baths] than the ancients, because of our use of linen.”

In the mid-17th century, clothing got a dusting of scented powder to make is smell fresh longer, and

after this nobles no longer felt the need to change clothing so often.

This lack of hygiene started to change toward the end of the Renaissance. Body odors became less tolerated,

and cleanliness became more important. Communal bathing in bath houses became popular once again

(as it once was in Rome) and was often accompanied by music and eating. But because nudity was taboo,

people wore clothes while bathing. As a courtesy, people offered a bath to their guests, and by the 15th

century, this was an established part of the code of hospitality. Handwashing before and after eating is
often mentioned in literature from this period, and basins appear regularly in illustrations. During the 14th
and 15th centuries, washing one’s hands became an elaborate ceremony at banquets, complete with a
servant called the Laverer, who brought water and towels to guests before a feast began. Outside Europe,
regular bathing was the custom. In India, the institution of Gushalkhana (a bathroom) was established by
the Mughal Kings in 1556. Oppressed by the heat and dust, the Kings constructed luxurious bathing and
massage facilities, but these were accessible only to the rich. Indian handbooks from the 17th century

describe bathing rituals that took place in bathing ghats, public baths on a riverbank.

Laundry

There were a large number of laundries in cities because of the importance of keeping linen white, but

women also did laundry at home and it continued to be backbreaking labor. Clothes had to be soaked,

boiled and beaten, then rinsed and wrung out by hand, and dried in the fresh air. Washboards and sticks

made doing the laundry a little easier, but it was still a very time-consuming task. Leftover soapy water was

given to the poor, because soap was still too expensive for most people. In addition to the regular laundry, a

“Grand Wash” took place twice a year. It was a symbolic ritual, lasting three days. Some sources say that that

it represented Hell, Purgatory, and Paradise. The “Grand Wash” was a symbol of purification, the triumph of

clean over unclean. Communal laundry rituals also existed in Asia and North and South America.

Water supply

Throughout the Renaissance, little progress was made in terms of bringing the water to the people. Water could

only be moved around by mechanical means. The homes of the wealthy and certain centers of culture, such as

monasteries, had water piped in, but the poor still had to hand-carry their water home from wells and rivers.

In 1698–99, the steam engine was invented by Thomas Savery and Thomas Newcomen. It would later be

perfected by James Watt and Benjamin Franklin. This invention would lay the groundwork for the water

distribution networks of the future.

Plumbing

Chamber pots continued to be used throughout the period, but now small rooms or closets were dedicated to the

purpose of using these chamber pots in private, hence the terminology “water closet” and “privy.” The contents of the
pots had to be hauled away manually. In 1596, Sir John Harrington, godson to Queen Elizabeth, installed water closets
for the queen and himself. However, he was ridiculed by his peers for this device, and never built another one.

Environmental impact
Pollution continued to be a problem, due to the increasing population in cities. Waste water from household uses and
laundries, as well as human waste, continued to be discharged into rivers and streams without any type of treatment.

Fashions
Clothing during the Renaissance was very important to the aristocracy, because it demonstrated one’s cleanliness and
wealth. Girls wore many layers of clothing: a chemise, stockings, a leather corset, a bodice, and petticoats, topped by
a gown. Both girls and women covered their hair with a scarf or hat. Boys dressed like their fathers, with shirts and a
fitted jacket, hose and breeches. Clothes were made out of wool, cotton, raw silk, linen, flax, leather or linen. Colored
fabrics were rare and for the most part only the rich could afford them; purples and reds were very difficult to obtain
and reserved for royalty exclusively.

AnD 19

centURIeS

In the course of the 18th century, personal cleanliness became a status symbol. More frequent bathing and hand
washing with soap and water were at first fashionable, and not until much later (in the late 18th and in the 19th
century) would they become indispensable. Science and technology made giant leaps forward. The early washing
machines (after 1850) revolutionized the laundry process. When bacteria and their role in causing infections and
contagious diseases were discovered in the middle of the 19th century, people understood the importance of hygiene
for good health. With the industrial era in full swing towards the end of the 1800s, the environmental impacts of
discharging untreated wastewaters began to become more apparent.

Soap
At the beginning of the 18th century, Marseilles had around 15 soap factories, making it the Mediterranean centre for
production and distribution of soap made from olive oil and natural soda.
Also in the 18th century, and continuing at the beginning of the 19th century, soap was heavily taxed as a luxury
product. When taxes were lowered and advances in chemistry integrated in the soap-making process, soap became
an everyday item for the majority, with a resulting rise in cleanliness standards.
In 1837, two young men merged their two businesses, a candle factory and a soap manufacturing business, into The
Procter & Gamble Company. In the United States, scientific discoveries allied with the overall industrial potential of the
country made soap manufacturing one of the nation’s most flourishing industries from 1850 onwards.

A brief history of soap-making in marseilles during the 18th and 19th centuries
1760: 28 factories totalling 126 boilers produce 9,000 tonnes of soap.
1786: 48 factories totalling 192 boilers, giving production capacity of 34,000 tonnes in the nine authorized working

months.

1789: 65 factories totalling 280 boilers produce 22,000 tonnes.
1793: Civil strife and downturn almost ruin the city. Soap industry,

however, rallies and survives the French Revolution.

1801: Peace returns, shipping redevelops. 73 factories

totalling 331 boilers.

1808: First soda factories open, using the Leblanc

manufacturing process. Prohibition on the
use of vegetable soda. Introduction of seed
oils, e.g., nut, rape, poppy and linseed,
cheaper than olive oil.

1817: Soap shares crash, only 15 factories

remain.

1820: 88 factories totalling 420 boilers.
1823: New oils available, such as palm and

coconut. Chevreul publishes first
definitive theory of saponification.

1842: Number of factories stable, but increase

in production capacity with the advent
of steam heating (50,000 tonnes). Palm
oil is used extensively for white soap with
more lather.

1863: Another growth crisis: Factories down to 52

for a production of 70,000 tonnes, although
demand continues to rise.

1885: 90 factories for 94,000 tonnes of soap, but lower

quality due to production cost-cutting.

Bathing
Throughout the 18th century, the belief that originated during the time of the
plague in the Middle Ages namely that disease could be contracted through water that touched the skin,
remained relatively unchallenged. The world would have to wait until the mid-19th century for French scientist
Louis Pasteur to prove this theory wrong. Until then, bathing was used as a medical treatment in thermal springs,
a leisure activity for the upper class at the health spas, and as a status symbol for the upper class generally.

Advances in science and technology

In 1774, Swedish chemist Karl Wilhelm Scheele discovered chlorine. Scientists would later discover that,

mixed with water, chlorine bleaches (Claude Berthollet) and that, mixed with a soda solution, chlorine

disinfects (Antoine Labarraque).

In 1783 Karl Wilhelm Scheele discovered a sweet-tasting substance he called OÅNlsüss (which we now

know as glycerol or glycerin) by boiling olive oil with lead oxide. Soap manufacture was revolutionised

in 1791 by the chemist Nicolas Leblanc, who devised a process of obtaining sodium carbonate (washing

soda) from sodium chloride (salt). Soap is produced from soda and fat. Leblanc’s process resulted

in the production of large quantities of good quality and low-cost soda. In 1823, inspired by this

discovery, French chemist Eugène Chevreul found that soap is not formed by fats combining with
alkali, but that these are first broken down into fatty acids and glycerol. Chevreul thus originated the
theory of saponification. Towards 1840 the process evolved further by the use of oils other than olive
oil, resulting in a still greater variety of end products. Chevreul’s discovery revolutionised the candle
industry. Another important leap forward was made when Belgian chemist Ernest Solvay (1838 –
1922) discovered that soda (sodium carbonate) could be produced on a larger, commercial scale from
ammonia, carbon dioxide and salt (sodium chloride). The Solvay process resulted in better quality soda

produced at a lower cost. On a different front, Frenchman Louis Pasteur (1822 – 1895) proved the link

between micro-organisms and infectious diseases with his famous “germ theory.” As of that moment,
the importance of hygiene for the protection of public health became a firmly established fact. In 1879,

William Procter invented Ivory Soap. In 1889, Gottlieb Daimler and Karl Benz invent the automobile,

revolutionising transport, which would have far reaching consequences for all of industry.

Laundry

The middle of the 19th century witnessed the appearance of the first mechanical washing machines.

Typically a closed tub with wooden paddles (agitators, later made of metal) allowed laundresses to work

in an upright position and not get their hands wet so much. Laundry was no longer the laborious and

timeconsuming ritual it had been in the past. The dirt and bad smells that accompanied overcrowding

in thecities were less and less acceptable to people, and this led to steady scientific progress. But before

washing machines were generally in use, large towns installed large public wash-houses or laundries. The

fixed tub with a hand-propelled rotating agitator was the forerunner of the rotating tub (gyrator) machine.

The forerunner of the modern drum machine that extracts the water during a rapid spin cycle would not

appear until into the 20th century. Laundry remained a ritual in the U.S. throughout the 19th century. A written

testimony by a late-19th century author in Practical Housekeeping reads: “Laundry and cooking go hand in

hand . . . On washing and ironing days, it is inadvisable to cook steak or fry fish, due to the smell. In addition, no

spinach, split peas, green beans (which need stringing), or stewed apples [should be prepared] because these all

take too long to prepare and time should be given to the laundry. More suitable dishes would be potatoes, pasta,

rice and corn, with a dessert of baked apples with cream: Quick, easy and very tasty.” Developments in laundry

products didn’t keep pace with the technological advances in washing machines: Until the end of the 19th century,
people still washed their clothes with soap flakes. Synthetic detergents would not appear for another 10 to 20 years,
during World War I.

Water supply and indoor plumbing
The wealthy had water piped into their homes, but for the urban poor, water hydrants or street pumps provided the only
source of water. To make matters worse, these were opened infrequently and not always on schedule. In the countryside,
people still drew water from rivers or wells. In 1829 and 1834, architect Isaiah Rogers built the Tremont Hotel in Boston
and the Astor House in New York, both with indoor plumbing and bathrooms in every room. A storage tank on the roof
supplied the bathrooms, kitchen and laundry with running water. Baths were copper or tin tubs, and the water for the
bath was heated in small gas furnaces. A steam engine-driven pump raised the water to the storage tank on the rooftop.
A simple system of pipes transported wastewater to the sewers. By the middle of the 19th century, the more widespread
installation of sewers in the cities provided more people with a way to dispose of their wastewater. In 1652, Boston had
already built the first public waterworks in the U.S., formed to provide water for firefighting and domestic use. Wooden
pipes were used until the early 1800s when the switch was made to cast iron. Later - in the 20th century - cement,
concrete, steel and iron would be used for the water distribution lines. In 1857, engineer J. W. Adams’ designs laid the
groundwork for modern sewer systems. In 1869, Chicago drew water from Lake Michigan via a tunnel. Steam engines
pumped the water from the tunnel beneath the lake. In 1906 the system was modernized. This station is still supplying
Chicago with water until this day. Chicago also was the first city to install a citywide sewerage system in 1885. By the
mid-1850s, many new homes had bathrooms. Copper and silver fixtures made room for stainless steel. Lead pipes were

used for cold-water supply lines, but were later replaced with iron, copper and sometimes even plastic. In the late 1730s,
the valve-type toilet came into use. The valves were rudimentary, however, and often leaked. By the late 1770s, the
hydraulics were improved, and this type of toilet is still in use today in many areas. There was another major breakthrough
around 1820, with the invention of the flush-type toilet by Albert Giblin in Britain. This was a siphon toilet with a water
reservoir for flushing when a rope was pulled. A certain Thomas Crapper worked on developing the piping of toilets, but
contrary to popular legend, he didn’t invent the flush toilet. His name, however, lives on in the slang for “toilet.” In 1857,
toilet paper was invented by the American Joseph Cayetti. In Asia, the wealthy already had toilet-like devices when in the
early 18th century. Soon, the cheaper uropean toilets began to appear in the homes of the less well off.

Environmental impact
All household waste waters, including the spent wash water (grey water) and water containing human waste (black
water), were discharged into the rivers and surface waters without any form of prior treatment. Regulations to protect
the environment did not yet exist. The second half of the 19th century witnessed the onset of the industrial era.
Inevitably, environmental pollution kept right in step with it, until public awareness and environmental regulation
would catch up – but that would not happen until much later, about the middle of the 20th century.

Fabrics
Clothing became more elaborate for both men and women. Women layered on a chemise, a corset, numerous
petticoats, and a dress. Men wore breeches or trousers, shirts, waistcoats, and coats, often with embroidery. For both
men and women wore clothing made of silk, satin, velvet, wool, and cashmere.

Biographies of famous scientists of the 18th and 19th centuries
Nicolas  Leblanc  -  French  chemist  (1742-1806),  perfected  a  process  for  preparing  sodium  carbonate,
contributing to the development of the use of minerals in the chemical industry.
Karl Wilhelm Scheele - Swedish chemist, born in Stralsund (1742-1786). Discovered chlorine, glycerol and
hydrocyanic (prussic) acid.
Hydrocyanic acid: Hydracid, HCN, intermediary in numerous reactions, but also highly toxic.
Antoine  Labarraque  -  Chemist  and  pharmacist,  born  1777  in  Oloron  (France),  died  in  Paris  1850.
Discovered disinfectant properties of bleach. Labarraque solution: A solution of sodium hypochlorite and
water  in  equal  measures.  Used  to  disinfect  objects,  but  not  advisable  for  wounds.  Other  uses  include
deodorising and bleaching.
Count Claude Berthollet - French chemist born 1748 in Talloires (France), died in 1822 in Arcueil. He
discovered  hypochlorites  and  applied  their  bleaching  properties  to  cloth.  He  also  perfected  chlorate-
detonated explosives, and went to Egypt with Napoleon Bonaparte.
Hypochlorite:  Salt  of  hypochlorous  acid  (sodium  hypochlorite  is  a  constituent  of  “Eau  de  Javelle,”  or
common household bleach).
Eugène Chevreul - French chemist born 1786 in Talloires, died in 1889 in Paris. Noted for his research
in organic chemistry, particularly the composition of fats, necessary to understand saponification. He also
worked on the theory of colour contrasts, and the results of his studies influenced the neo-impressionist
painters.  Saponification:  A  chemical  reaction  from  an  ester  molecule,  yielding  a  carboxylase  ion,  a
conjugated base of carboxylic acid and an alcohol.
Ernest  Solvay  -  Belgian  industrialist,  born  in  Rebecq-Rognon  (Belgium)  (1838-1922).  Founder  or
benefactor  of  various  scientific  bodies,  he  originated  a  manufacturing  process  for  sodium  carbonate
whereby a concentrated solution of sodium chloride is saturated with ammonia, carbon dioxide is passed
through it, and the product is calcinated (1861-1865).

centURIeS

In course of the 20th century, hygiene became more and more of a priority and the role of soap became

even more important. Around the turn of the century, oil and soap manufacturers merged. The invention

of the steam generator, electricity and innovative manufacturing technology all worked together to

support the growth of the industry. Development of gentler bath soaps and laundry detergents began

in the early 20th century, and the remainder of that century would witness continued invention of new

products and the diversification of existing ones. The emergence of wastewater treatment plants, the

rise in environmental awareness and the increase in environmental regulations after ~ 1970 prompted

– among other things - the development of biodegradable detergent ingredients. The first synthetic
detergents appeared in 1916. Production of household detergents began during the 1930s in America,
but did not really take off until after World War II, with development in 1946 of all-purpose detergents.
During the 20th century the development of washing machine and dryer technology accelerated,
resulting in ever more practical and efficient machines. This effort was, at least in part, driven by
the parallel, rapid development of a wide range of synthetic and mixed fibers that fueled the textile
industry.

Soap and synthetic detergents

During the the World Wars, in particular World War II, detergent research was spurred by shortages

of animal and vegetable fats, plus the need for armies to wash clothes in hard, cold water. The first

detergents were mainly used for dish washing and laundering delicate fabrics. From the 1950s onwards,

soap products were gradually replaced by synthetic detergents derived from petroleum by-products,

vegetable oils and animal fats. Development of all-purpose detergents began in 1946, when the first

detergents that contained surfactants and builders were introduced in America (“built” detergents). This

combination of ingredients worked very well because the surfactant would remove the dirt, whereas the

builder would make the surfactant more effective. Synthetic surfactants held a significant performance

advantage over soap: they performed much better in cold, hard water. Synthetic detergent production

surpassed the highest level ever achieved by soap in 1957. Detergents could now be found in many common

household products, including personal hygiene products, and progress has continued at a rapid pace ever

since. In 1964, biodegradable LAS (linear alkylbenzene sulfonate) replaced branched

alkylbenzene sulfonate, its non-biodegradable counterpart. The worldwide

consumption of detergents and soap today (2003) is more than 27 million

metric tonnes.Soap accounts for 9 million tonnes.

Laundry

The first electric washing machine was produced in the U.S.

in 1908. It featured a top-mounted electric motor-driven

agitator. Towards 1920, new machines were fitted with

a horizontal cylinder. But this did not prevent manual

machines from prospering. At the end of the 1940s,

electric machines were fitted with an impeller. During

the 1950s, a heating element and automatic spin

cycle were added (some machines had separate

spinners, alongside the wash drum). The 1960s
saw the advent of automatic machines which, at

the touch of a button, wash, rinse and spin in the

same drum, at first mounted vertically, and later

horizontally (“front loaders”).

By the end of the 20th century, washing machine

technology had continued to evolve. Electro-

mechanical controls (knobs) had been replaced by

electronic ones (push-buttons). The newer machines

required less water and newer laundry products worked

better at lower temperatures, rendering the laundry process

more energy-efficient. Concentrated laundry products required

less transport, less shelf-space and less packaging. New wash

cycles appeared, such as those for silk, wool and delicates, and short wash. In some developing countries, even today,
manual practices still exist, as shown in these photographs of people in India, doing the laundry on the banks of the
Ganges, and of people on the African continent.

Science and technology1
1908 The first electric washing machine is made in the U.S.
1927 Filo T. Farnsworth invents television. TV advertising and soap operas would follow!
1938 Wallace Carothers invents nylon.
1958 Jack Kilby and Robert Noyce invent the microchip, laying the groundwork for modern computers.
1964 The biodegradable anionic surfactant Linear Alkylbenzene Sulfonate (LAS) replaces its branched predecessor.
1991 Tim Berners-Lee invents the Internet.

Water supply and indoor plumbing
As the 20th century progressed, indoor toilets and running water—often both hot and cold—became the norm,
especially in cities. In rural areas, however, outhouses continued to be used, in some areas until the 1960s. Beyond
that, most communities in developed countries had main water supplies and sewage systems.
At the start of the 21st century, the trend in bathrooms was to make them bigger and more luxurious.
Bathrooms no longer consist of just a standard toilet, sink, and bathtub/shower combination. New bathrooms are
large, tiled rooms with a toilet and a bidet, two or more sinks, a stand-alone shower, and a roomy bathtub, often with
a whirlpool bath. The poor in some developing countries, however, must still haul water from a communal tap - water
which is not guaranteed safe to drink - and share communal toilets. In many countries outside Western Europe and
North America, running water that is piped into the home may not be safe to drink, and may need to be boiled or
chemically treated.

Environmental impact
Centralized wastewater treatment emerged in the form of municipal sewage treatment works in the late 19th
and 20th centuries in the cities of the U.K. and the United States. There are, by origin, three types of wastewater:
stormwater from runoff after rains, sanitary or domestic wastewater from homes and industrial waste water.
Early sewage treatment works would accept all three types, but ran into problems with overflow and too
highly polluted industrial wastewaters. After ~ 1950, as public concern about the environment increased, the
number of regulations designed to protect the environmental also increased. In modern sewage treatment
systems, stormwaters by-pass the treatment works and are discharged directly to surface waters. Domestic
wastewater is treated at the municipal sewage treatment plant and then discharged. Manufacturers are
often required to pre-treat their wastewater prior to sending it to a municipal sewage treatment plant.
Detergent  manufacturers  started  developing  biodegradable  detergents  in  the  1960s.  These  detergents
contain  surfactants  and  other  cleaning  agents  that  are  effectively  removed  from  wastewater  during
sewage treatment. However, not all countries can afford the luxury of wastewater treatment, even though
it  is  badly  needed  and  often  required  by  law.  When  wastewater  treatment  is  not  available,  sewage  is
discharged directly into surface waters which causes pollution even today. It has been shown that the
development of modern wastewater treatment significantly improves the quality of surface waters. Since
detergent and cleaning product ingredients are well removed during wastewater treatment, there are no
adverse ecological effects from the use of laundry detergents and household cleaning products.

Fabrics
During the late 19th and 20th centuries, man-made fibers were developed. Until then, fabrics were made
from natural fibers: cotton, wool, silk, jute or flax. Synthetic fibers (nylon, polyethylene terephtalate, acrylics,
polyurethane, polypropylene) were manufactured from polymers, made from petroleum byproducts or
natural gas. The first women’s nylon stockings caused quite a stir in 1940! Fabrics from synthetic fibers
were cheaper to make, easier to dye and offered more processing flexibility compared to the natural
fabrics. Also the characteristics of the fabric could more easily be tailored for certain purposes: think about
the revolution in outdoor wear and sportswear in the 1990s, with fleece, Polartec®, wrinklefree fabrics,
water-repellent fabrics, stain-resistant fabrics, thermal fabrics, breathable fabrics - the list goes on an on.
These rapid developments in the textile industry put pressure on the fabric care industry to keep up, as
people needed affordable technology to take care of an ever expanding range of fabrics. In addition, the
customers of the late 20th and 21st centuries, often part of dual-career families, don’t want to spend a lot
of time on laundry, and they want their clothes to stay looking newer, longer.

The milestones in the history of washing machines and dryers during the 19

and 20

centuries

Early 1900s Wooden wash tubs are replaced by metal tubs.

1907 Maytag Corporation began manufacturing a wooden-tub washing machine with a flywheel, still

manually operated with a rotary handle.

1922 Maytag Corporation introduces the agitator system for moving the water around in the drum,

rather than dragging the fabrics around in the water.

1908 First electric-powered washing machine is invented by Alva J. Fisher.

1911 Whirlpool Corporation, then called the Upton Machine Co. is founded in St. Joseph, Michigan

and starts producing electric motor-driven wringer washers.

1915 The first electrical clothes dryers appear.
1930s John W. Chamberlain of Bendix Aviation Corporation invents a machine that can wash, rinse,
and extract water from clothes in a single operation.
1947 The first top-loading automatic washing machines are introduced by the forerunner of the
Whirlpool Corporation.
1951 The first automatic washing machines are made in Europe. The first computer-controlled
automatic washing machines appear.

1950 Many technological advances follow. Among hundreds of systems tested, only two washing

systems survive until this day: the agitator system and the tumbling system. Wash cycles and products
are developed for new fabrics and a greater range of wash conditions.

A brief history of Procter & Gamble
1837 During a difficult period, and following the advice of their father-in-law, two young men (married to sisters Olivia

and Elizabeth Norris) merged their two businesses. James Gamble had a soap factory and William Procter had just
started a candle factory. And so the first Procter & Gamble enterprise came into being in Cincinnati, Ohio.

1859 Sales reached $1 million; 80 employees.
1860s During the Civil War, P&G won contracts with the army for the supply of soap and candles. A period of great

activity which confirmed their market position and built their reputation when soldiers returned home with
P&G products.

1878 Floating soap was discovered by chance: A workman in charge of production of one of the 24 types of soap let

the mixture boil too long. Full of air bubbles, the soap floated. It was named “Ivory” and became the company’s
brand name. Inexpensive and of high quality, it was launched amidst an extensive promotional campaign in the
press and on posters, which became a landmark in advertising history.

1887 To counteract the rise of trade unions, the company established one of the first employee profit-sharing schemes

in the world. Today, the 100,000 employees in the group hold 25% of the capital.

1890 Creation of one of the earliest private research and development facilities - A successful multimillion dollar

company.

1915 First P&G factory established outside the USA, in Canada.
1919-1920 P&G sells directly to retailers and hires 450 sales representatives.
1924 Awareness of changing washing habits and the growing demand for laundry products prompts P&G to set

up a market research department. From then onwards, the dialogue between P&G and consumers was firmly
established. The concept that good customer service requires understanding the market, takes hold.

1926 In response to the increasing popularity of perfumed beauty soaps, P&G launches the Camay brand.
1930s P&G researchers study the discoveries made by German chemists during the World War I in a bid to replace

soap with a synthetic product.

1931 The P&G marketing organization organizes itself around the brands.
1933 Launch of the Dreft brand, the first synthetic detergent, specifically designed for delicate fabrics. That year,

the P&G launches the “soap opera”, a serial daytime TV entertainment program, interspersed with brand
advertising.

1934   P&G launches Drene shampoo.
1945   The company’s net worth is $350 million.
1946   P&G launches Tide, the first all-purpose laundry detergent. It would become a phenomenal success.
1954   P&G starts European operations.
1955   P&G introduces the Crest brand, the first fluoride-containing toothpaste
1960   P&G launch the Downy brand, the first fabric conditioner.
1964   The American Dental Association endorses Crest toothpaste.
1972  P&G launches the Bounce brand, the first softener sheet for dryers.
1980   P&G operations span 23 countries worldwide, with a turnover of $11 billion s - 35 times that of 1945.
After 1980 Global development continues, frequently through acquisitions.
1984   Launch of “Tide Liquid”. In this period, P&G introduces the first dosing device for liquid detergents

‘vizirette’ which subsequently became a common dosing device that allows consumers to dose in the
heart of the wash (to improve dissolution kinetics and performance while avoiding sump losses).

1986   P&G develops a “2-in-1” shampoo/conditioner brand: Pert Plus/Rejoice would become a market leader.
1988   P&G announces a joint venture agreement in China.
1995   P&G receives the National Medal of Technology - the highest award in the USA for achievement

in technology - for creating, developing and marketing products that improve quality of life for
billions of people worldwide. P&G is quoted among the “Best-of-the-Best” in customer service,
along with L. L. Bean, American Express, The Limited and Mariott. The company is also recognized
as a leader in the areas of marketing, sales management and technology management2.

1998 P&G supports the ‘A.I.S.E. Code of Good Environmental Practice’, a voluntary initiative of A.I.S.E.

to promote sustainable production and consumption. A.I.S.E. is the European industry association
for detergents and cleaning products.

1998 P&G starts to participate to the (ongoing) ‘A.I.S.E. Washright campaign’, which promotes the

sustainable consumption of household laundry detergents across Europe (www.washright.com)

1999 P&G actively participates to the HERA progamme (HERA = Human & Environmental Risk Assessment),

a joint A.I.S.E./CEFIC initiative to provide risk assessments on ingredients used in household cleaning
products (see www.heraproject.com)

2001 P&G introduces ‘Ariel Liquitabs’, the first P&G fully soluble liquid laundry detergent pouches which

combines strong performance, convenience and textile care.

2002 P&G launches the new Ariel powder tablets.

2004 P&G becomes an active member of the A.I.S.E. “Charter for Sustainable Cleaning*. This initiative

promotes a life-cycle approach to sustainability throughout all product categories of A.I.S.E., through

independent assessment and leading to the reporting on industry’s sustainability performance (see

www.sustainable-cleaning.com)

2005 P&G introduces the ‘Safe Use Icons’ on its products. These are a new set of icons developed by

A.I.S.E. which provide consistent communication on the safe use of products.

(see www.aise.eu, www.sustainable-cleaning.com)
2006  A.I.S.E. launches the ‘Laundry Sustainability Project’ (LSP). With this, P&G and other detergent
manufacturers  intend  to  promote  sustainability  by  educating  consumers  on  how  to  dose  correctly
when using ‘compact’ laundry detergents (see www.aise.eu).
2006    A.I.S.E.  initiates  the  (ongoing)  ‘Save  Energy  and  Water  project’  which  aims  at
encouraging  the  use  of  low-temperature  and  auto  programs  on  automatic  dishwashers.  (see
www.saveenergyandwater.com)

2008 P&G renews the scientific website www.scienceinthebox.com which now includes the

Sustainability-in-the-Home module. This offers easily accessible information to consumers around how
to use laundry and cleaning products in a more sustainable way.

The Future

P&G continues to focus on its core brands and technology. The company has also made a firm

commitment to sustainability in the broadest sense - social, economical and environmental. As quoted

from A.G. Lafley, CEO of P&G : “We take pride in serving more than two billion consumers every day,

and creating value for shareholders. This is necessary, but not enough. We must not only sustain business

growth. We must also contribute to the sustainability of the world we live and work in today for the

benefit of our children and grandchildren tomorrow.” In 2007, P&G renewed its sustainability programme

and developed strategies and goals for its products, manufacturing operations and sites, as well as for the

social responsibility programmes, employee engagement and external sustainability partnerships (More info
