Soap is a salt of a fatty acid used in a variety of cleansing and lubricating products. Soaps can change the surface tension of water. In a domestic setting, soaps are surfactants usually used for washing, bathing, and other types of housekeeping. When used for cleaning, soap solubilizes particles and grime, which can then be separated from the article being cleaned. In industrial settings, soaps are used as thickeners, components of some lubricants, and precursors to catalysts.
