Description

12-Hydroxystearic Acid is a high-purity, long-chain fatty acid derivative featuring a hydroxyl group at the 12th carbon position. This unique molecular structure provides excellent thickening, gelling, and lubricating properties, making it a critical performance additive in numerous industrial formulations. It is essential for manufacturers in the cosmetics, lubricants, plastics, and coatings industries seeking to enhance product stability, texture, and performance. Our global supply ensures consistent quality and reliable availability for your production needs.

Application

• Cosmetics & Personal Care: Acts as a highly effective thickener, opacifier, and stabilizer in creams, lotions, lipsticks, and deodorants, providing a rich, non-greasy texture.
• Lubricants & Greases: Serves as a key component in lithium and calcium complex greases, imparting excellent water resistance, high-temperature stability, and superior mechanical properties.
• Polymer & Plastics Industry: Functions as an internal and external lubricant and release agent in PVC, polyolefins, and engineering plastics, improving processing and surface finish.
• Coatings & Inks: Used as a rheology modifier and anti-settling agent to control flow, prevent sagging, and enhance the application properties of paints and printing inks.
• Adhesives & Sealants: Provides thixotropic properties and structural viscosity, aiding in application control and preventing slump in non-flow formulations.
• Chemical Synthesis: A valuable intermediate for producing esters, amides, and other derivatives used in surfactants, plasticizers, and specialty chemicals.
