Description

Hydroxyoctadecanoic Acid, Monoester With Propane-1,2-Diol is a specialized fatty acid ester derived from hydroxy stearic acid and propylene glycol. This compound is valued for its excellent emulsifying, stabilizing, and conditioning properties, making it a versatile intermediate and functional additive. It is primarily sought after by manufacturers in the personal care, cosmetics, and industrial lubricant sectors for formulating high-performance products.

Application

• Cosmetic & Personal Care Formulations: Acts as a non-ionic emulsifier, emollient, and viscosity modifier in creams, lotions, and hair conditioners.
• Pharmaceutical Excipient: Used as a solubilizer and carrier in topical ointments and controlled-release drug delivery systems.
• Industrial Lubricants & Greases: Serves as a thickening agent and provides enhanced lubricity and stability in specialty lubricant formulations.
• Plastic & Polymer Additive: Functions as an internal or external lubricant and processing aid in polymer production.
• Textile & Leather Processing: Employed as a softening agent and finishing auxiliary to improve material handle and quality.
• Food-Grade Applications (where certified): Potential use as an emulsifier or release agent in food contact materials and packaging.
