How Soap
Is Made
Soap is said to have been discovered long ago when animal sacrifices were made. The fat from
the animals that were killed for a sacrifice was mixed with the wood ash(natural lye) from the
burning wood on the altar. After it rained the water that was washed down the mountain into the
river where the people did their washing was found to clean their clothes better than clear water
and it created lather. Soap is made by combining fats and/or oils with alkalies which create a
process known as saponification. This is the chemical reaction which converts the fatty acid and
the alkali into soap. Liquid soap is made by combining a fatty acid with Potassium hydroxide and
hard bar soap is produced by combining a fatty acid with Sodium hydroxide. These solutions are
commonly known as lye. Once an emulsion has formed, a soap stock for hot processing has to
cook for several hours. Cold processing is somewhat different in that it requires no cooking at all.
The difference between hot and cold processing soap is that cold processed soap has to cure for
several weeks before it is properly neutralized and ready for use. Hot processed soap does not
have to cure because the long cooking period and heat actually neutralizes the soap to have it
ready for use sooner. Some neutralizers may also be added to help speed this process.
Transparent soap is made by adding solvents such as alcohol, glycerin and sugar solutions and
then cooked for several hours. Alcohol can then be cooked out of the soap for an alcohol free soap.

Most commercial soaps are created cheaply using buffers and chemicals to stabilize, preserve,
and enhance the performance of the product. These chemicals although effective are not always
safe to use on the skin. Sometimes there is a result of allergic reactions and skin irritations which
can lead to other problems. Most naturally made products don't have a shelf life like many of these
products but natural preservatives and supply on demand products will offer you an extended
period for purchasing and using natural products. Some natural preservatives have been known to
give an indefinite shelf life to natural body care. These natural preservatives are not always as
inexpensive as the unnatural ingredients used by some commercial suppliers, but are well worth
reaping the benefits of something good for your skin.
