Description

Oxybis(2-Hydroxypropane-3,1-Diyl) Dimyristate is a high-purity, non-ionic surfactant and emulsifier derived from myristic acid and propylene glycol. This compound is valued for its excellent stability and compatibility in formulations requiring a lipophilic character and mild emulsifying properties. It serves as a critical functional ingredient for manufacturers in the personal care, cosmetics, and pharmaceutical industries, where it acts as a solubilizer, emollient, and co-emulsifier.

Application

• As a primary or co-emulsifier in cosmetic creams, lotions, and sun care products.
• As a solubilizer for fragrances, essential oils, and active ingredients in clear gels and aqueous formulations.
• As an emollient and skin-conditioning agent in personal care products like body butters and lipsticks.
• As a stabilizer and texture enhancer in pharmaceutical ointments and topical delivery systems.
• As a lubricant and release agent in industrial applications and polymer processing.
• As a key ingredient in specialty chemical formulations requiring a non-ionic surfactant with a specific HLB value.
