Manufacturing Process

stearic acid manufacturing process

The production of commercially available triple-based stearic acid is carried out by a compression process. Fats and oils are hydrolyzed at high pressure and high temperature to form chains of fatty acids and glycerol. The product is purified by washing and distillation before being compressed to remove oleic acid. Compression is done in several stages, each with different purity. The triple press process provides the highest purity stearic acid compared to the double and single press processes.
