Description

Isooctadecanoic Acid, Ester With 1,2,3-Propanetriol is a synthetic ester, specifically a glycerol triester of isostearic acid. This compound is valued for its excellent stability, emollient properties, and compatibility with a wide range of cosmetic and industrial formulations. It serves as a key ingredient for manufacturers in the personal care, lubricant, and polymer industries seeking a high-performance, non-greasy ester with superior oxidative and hydrolytic resistance.

Application

• Cosmetic & Personal Care Formulations: Acts as a premium emollient and skin-conditioning agent in creams, lotions, sunscreens, and makeup products, providing a smooth, non-oily feel.
• Lubricants and Greases: Used as a synthetic base oil or additive in specialty lubricants, offering good low-temperature fluidity and thermal stability.
• Polymer & Plastic Additives: Functions as an internal or external lubricant and plasticizer in PVC and other polymer processing to improve flow and surface finish.
• Metalworking Fluids: Employed as a component in synthetic and semi-synthetic cutting and drawing fluids for enhanced lubrication and corrosion protection.
• Textile Auxiliaries: Serves as a softening agent and lubricant for fibers and yarns to improve processing and hand feel.
• Industrial Coatings & Inks: Utilized as a flow modifier and viscosity regulator to enhance application properties and final film characteristics.
