Common Name Stearic acid
Description Stearic acid, also called octadecanoic acid, is one of the useful types of saturated fatty acids that comes from many animal and vegetable fats and oils. It is a waxy solid, and its chemical formula is CH3(CH2)16COOH. Its name comes from the Greek word stear, which means tallow. Its IUPAC name is octadecanoic acid. -- Wikipedia
