Description

9,10-Dihydroxystearic Acid is a high-value, naturally-derived fatty acid derivative characterized by the presence of two hydroxyl groups on the 9th and 10th carbon atoms of its stearic acid backbone. This unique bifunctional structure makes it a versatile intermediate and additive, prized for its ability to modify surface properties and contribute to polymer synthesis. It is essential for manufacturers in the specialty chemical, polymer, and personal care industries seeking to develop products with enhanced hydrophilicity, lubricity, or cross-linking potential.

Application

• Polymer & Resin Modification: Acts as a monomer or co-monomer for producing polyesters, polyurethanes, and alkyd resins, imparting flexibility and improved adhesion.
• Surfactants & Emulsifiers: Serves as a key raw material for synthesizing non-ionic surfactants and emulsifiers used in industrial and cosmetic formulations.
• Lubricants & Greases: Functions as an additive or base component in bio-based lubricants and metalworking fluids, offering excellent lubricity and stability.
• Personal Care & Cosmetics: Utilized in the production of emulsifiers and conditioning agents for creams, lotions, and hair care products.
• Textile & Leather Processing: Employed as a softening agent, lubricant, or finishing agent to improve the handle and quality of textiles and leather.
• Chemical Intermediate: A crucial precursor for further chemical synthesis, including the production of dicarboxylic acids and other specialty derivatives.
