Soaps
« on: January 12, 2017, 03:01:03 PM »
Soaps are sodium or potassium salts of higher fatty acids (are organic acids that have more than 16 carbon atoms in their molecules) like stearic, palmitic and oleic acids. Soap is a metallic salt of saturated (CnH2n+1COOH) or unsaturated (CnH2n-1COOH) higher fatty acid. There may be Pb, Mg, Ca or other metallic salts. The sodium soaps are called hard soaps and the potassium soaps are known as soft soaps. Soaps are obtained from oils and fats. For example, tri-stearin is got from beef and mutton tallow, tri-palmitin from palm oil and tri-olein from lard (pig fat), olive oil and cotton seed oil.
