Description
Buy High-Purity Stearic Acid 99% | Cosmetic & Industrial Grade
Stearic Acid (CAS No. 57-11-4, molecular formula C₁₈H₃₆O₂) is a saturated fatty acid typically derived from palm oil or animal fats. This white, waxy flake-like substance has a purity of 99% and is suitable for a variety of uses in cosmetic, biochemical, and synthesis applications.
Premium Stearic Acid for Cosmetic and Biochemical Applications
In cosmetic and personal care, Stearic Acid functions as an emulsifier, thickening agent, and stabilizer in products like lotions, soaps, shaving creams, and deodorants. In biochemistry, it is used for membrane studies and lipid research. Learn more about fatty acid applications in cosmetic formulations from the International Journal of Cosmetic Science.
Industrially, Stearic Acid is valued for its lubricating and softening properties, as well as for producing stearates (metallic salts of stearic acid) used in plastics, rubber, and candles. It also serves as a release agent, a hardener, and a surface-active agent in formulations.
