Soap gets rid of bacteria and viruses, while also cleansing the skin. They are made up of a fatty substance, mixed with an alkaline agent. The physical form of the soap (solid, liquid or paste) depends on the fats/oils and alkaline agents used to create it.
Soap is a salt of a fatty acid used in a variety of cleansing and lubricating products. In a domestic setting, soaps are surfactants usually used for washing, bathing, and other types of housekeeping. In industrial settings, soaps are used as thickeners, components of some lubricants, and precursors to catalysts.
