Soap is a salt of a fatty acid used in a variety of
cleansing and lubricating products.
In hand washing, as a surfactant, when lathered with a
little water, soap kills microorganisms by disorganizing
their membrane lipid bilayer and denaturing their proteins.It also
emulsifies oils, enabling them to be carried away by
running water.
Soap is created by mixing
fats and oils with a base.Humans have used soap for
millennia; evidence exists for the production of soap-like materials in
ancient Babylon around 2800 BC.
