Description

Methyl 12-Hydroxystearate is a high-purity fatty acid ester derivative of 12-hydroxystearic acid, valued for its unique combination of a long hydrocarbon chain and a polar hydroxyl group. This bifunctional structure makes it an essential intermediate and performance additive in advanced chemical synthesis and formulation. It is particularly sought after by manufacturers in the lubricants, cosmetics, polymers, and specialty chemicals industries seeking to enhance product properties such as viscosity, stability, and surface activity.

Application

• Lubricant & Grease Formulation: Acts as a thickening agent, viscosity modifier, and anti-wear additive in synthetic lubricants and high-performance greases.
• Polymer & Resin Industry: Serves as a plasticizer, internal lubricant, and co-monomer for modifying the flexibility and processing characteristics of polymers like PVC and polyesters.
• Cosmetics & Personal Care: Used as an emollient, viscosity controller, and stabilizer in creams, lotions, and lipsticks for its smooth texture and skin compatibility.
• Chemical Synthesis: A key intermediate for producing surfactants, emulsifiers, and other ester derivatives through further chemical reactions.
• Coatings & Inks: Functions as a flow aid and dispersing agent to improve leveling and pigment wetting in coating systems.
• Metalworking Fluids: Incorporated as a lubricity agent and corrosion inhibitor in cutting and drawing fluids.
