Audited Supplier Stearic acid is an important chemical raw material. It is lump, flake, powder or granular solid, insoluble in water, soluble in benzene, toluene, chloroform, tetrachloromethane, carbon, sulfide, ethanol, acetone. It is widely used in food, cosmetics, plastic, robber, metal soap, medicine and other organic chemicals.
Classification of stearic acid
Industrial products are divided into first-level (formerly known as three-press, after three presses), second-level (formerly known as second-press, after two presses) and third-level (formerly known as first-press, after one press or not). It is a mixed acid containing mainly stearic acid and palmitic acid. Primary and secondary stearic acid are white waxy solids with luster or crystal particles. Tertiary stearic acid is a light yellow waxy solid. The first-level acid is also called cosmetic grade stearic acid. The third-level acid is rubber grade. Stearic acid and secondary acid are in between, products used by customers who do not have very high quality requirements, such as mid-range hard salt. First-grade stearic acid can be used in the food industry. The primary acid mainly uses plant raw materials, also known as plant acid. Tertiary acid is animal raw material, usually animal acid.
