Description

Methyl 10-Hydroxystearate is a high-purity fatty acid methyl ester derivative, specifically the methyl ester of 10-hydroxystearic acid. This compound serves as a versatile chemical intermediate and functional additive, valued for its hydroxyl group which provides a reactive site for further chemical modifications. It is essential for manufacturers in the cosmetics, lubricants, polymer, and specialty chemical industries seeking to develop products with enhanced properties such as emulsification, viscosity modification, or bio-based content.

Application

• Cosmetic & Personal Care Ingredients: Acts as an emollient, viscosity modifier, and intermediate for synthesizing esters in creams, lotions, and makeup.
• Lubricant & Grease Formulation: Used as a bio-based raw material or additive to improve lubricity, oxidative stability, and low-temperature performance.
• Polymer & Resin Modification: Serves as a polyol component or plasticizer intermediate in the production of polyurethanes, alkyd resins, and other polymers.
• Surfactant & Detergent Synthesis: A key intermediate for manufacturing non-ionic surfactants and emulsifiers via ethoxylation or other reactions.
• Pharmaceutical Intermediates: Employed in the synthesis of specialized drug delivery systems and active pharmaceutical ingredients (APIs).
• Research & Development: Used in academic and industrial labs as a standard or building block for novel chemical synthesis.
