Soap is a general term for fatty acid metal salts. The general formula is RCOOM, where RCOO is fatty acid radical and m is metal ion. The carbon number of fatty acids in daily soap is generally 1- 18. Metals are mainly alkali metals, such as sodium or potassium, but ammonia and some organic bases, such as ethanolamine and triethanolamine, are also used to make soaps for special purposes.

Broadly speaking, fatty acid salts obtained by saponification or neutralization of oil, wax, rosin or fatty acid with alkali can all be called soap. Soap can be dissolved in water and has the function of washing and decontamination. All kinds of soaps are soaps, also known as soaps, metal soaps and compound soaps.
