Soaps have been valued for generations for their
ability to clean clothing and household products as
well as for bathing. Soap making is a craft that is
often neglected in history whether it is the discussion of skills of 19th
century or of the colonial period. Soap is manufactured when very basic ingredients, such as oils (or fats), water and lye
(sodium hydroxide) undergoes a chemical process known as saponification.
Archeological Findings
The history of soap manufacturing dates back to almost 2800 B.C. The first such finding was done by the archaeologists
when they discovered a clay cylinder, which was covered by a material similar to soap. The cylinders were found out from
the remains of the Mesopotamian civilization and the archaeologists were astonished on their finding when they decoded
the message that was on the excavated cylinders. In reality, it was the technique of soap making that described it as a
boiling of fats along with ashes. But another matter that was left half way was soap like material, which was seen
covering the cylinder. As the message given on cylinders did not indicate the use of this material the archeologists were
left helpless.
Apart from the remains of Mesopotamian civilization, the archeologists also gained more information on soap history from
the excavations of different civilizations. One such information was found from the Mesopotamian civilization from the
artifacts of Pharaoh that suggests the various ways of soap making. Information on History of soap making has also been
found from different books, like the medical text that was written by Papyrus. History of soap making also explains the
various ways of soap manufacturing and one such way is to combine animal as well as vegetable fat along with alkaline
salts. The substance, which is finally received, could be used for bathing or it can even be used to treat skin problems.
Soapmaking in Bible
The method of soap making was also introduced in holy books like Bible, in which it was conveyed that the Israelites use
vegetable oils and ashes to make a substance like hair gel. Later in the second century A.D, noted physician Alexandria
coined out the commercial uses of soaps by advocating soap to be used as a topical treatment for patients in order to
keep them clean.
How does soap get its name
The soap got its name (according to an ancient Roman legend) from Mount Sapo, where animals were sacrificed. Rain
washed a mixture of wood ashes and melted animal fat, or tallow, down into the clay soil along the river tiber. Women
found this clay mixture to be highly helpful in making the cleaning easy and effective. The ancient Gauls and Germans are
also credited with the discovery of a substance called soap, made of tallow and ashes, which they used to tint their hair,
red.
As the Roman civilization advanced, so did the bathing. The first of the famous Roman baths, supplied with water from
their aqueducts, was designed around 312 B.C. These baths were highly luxurious that makes bathing very popular. By
the second century A.D., the Greek physician, Galen advocated soap for both cleansing as well as medicinal purposes.
After the fall of Roman empire in 467 A.D., bathing habits declined and as a result of which, much of the Europe felt the
impact of filth upon public health. The lack of cleanliness and unsanitary living conditions led heavily to the plagues of the
Middle Ages and especially to the Black Death of 14th century. The poor cleanliness and bathing habits remain same till
the 17th century in much of the Europe. However there were still some areas in the medieval world where personal
cleanliness remained essential. Daily bathing was a normal custom in Japan during the Middle Ages and in Iceland, pools
warmed with water from Hot Springs were highly popular among people at gathering places on Saturday evenings.
Manufacturing of soap became an established craft in Europe by the 7th century. Soap manufacturers guilds guarded and
protected their trade secrets closely. The soap makers use vegetable and animal oils with ashes of plants along with
fragrances to offer a variety of soaps for bathing, shampooing, shaving as well as laundering.
Advent of Commercial Soapmaking
Italy, Spain and France were emerged, as the early centers of soap manufacturing with their ready supply of raw
materials, like oil from olive trees. The English started soap production during the 12th century. Around the year 1622,
soap business was in great demand, which prompted King James I to grant monopoly to a soap maker for $100,000 a
year. For several years during the 19th century, soap was heavily taxed as a luxury item in various countries. When the
tax was lowered, it became available to ordinary people and as a result the cleanliness standards improved.
Commercial soapmaking started in the American colonies in 1608, which was the time when several soapmakers arrived
on the second ship from England to reach Jamestown, VA. However, for several years, soapmaking remains primarily a
household activity. Finally, professional soapmakers started regularly collecting waste fats from households in exchange
for soaps.

An important step towards large-scale soap manufacturing occurred in 1791 when a French chemist, Nicholas
Leblanc, patented a technique for producing soda ash, or sodium carbonate, from common salt. Soda ash is
an alkali, which is obtained from ashes by combining it with fat to produce soap. The Leblanc technique
produces inexpensive soda ash in good quantities.
Discoveries and Inventions
The science of modern soapmaking commenced with the discovery of another French chemist, Michel Eugene Chevreul,
who described the chemical nature and the relationship of fats, glycerin and fatty acids. The study demonstrated the
basis for both fat and soap chemistry.
Another important discovery that led to the advancement of soap technology was that of a Belgian chemist - Ernest
Solvay, who in mid-1800s described an ammonia process by which common table salt, or sodium chloride can also be
used to make soda ash. Solvay's procedure helped in reducing the cost of obtaining this alkali, and increased both the
quality as well as quantity of the soda ash available for producing soap.
Together with the development of power to operate factories, the discoveries and inventions in the field of soapmaking
made the soap manufacturing one of the fastest-growing industries in developed countries. The broad availability of soap
changed its condition from a luxury item to an everyday necessity and its widespread use lead to the development of
milder soaps for bathing. Special soaps were developed for uses in the washing machines that were available to
consumers by the turn of the century.
