12-hydroxy Stearic Acid 12-Hydroxy Stearic Acid (12-HSA) is the saturated counterpart of P-10 Acid.12-HSA is produced from hydrogenated castor oil (Castorwax). Its high melting point and hydroxyl bearing chain produce glycerine-free gel structures of great strength and workability, the dominant feature of heavy duty greases. The hydroxystearic characteristics are utilized in cosmetics, toilet goods, wax blends, polishes, inks and hot melt adhesives. Reaction with acrylic esters produces hard, durable, thermosetting polymers used in high quality finishes. In coatings resins, the hardness, high melting point and reactive hydroxyl group are utilized in both solvent and water-based polymers as well as plasticizer systems.12-HSA is also a major component in lithium and calcium based multi-purpose lubricating greases. It also functions as an activator and internal lubricant for natural and synthetic
