  • Applications

    Myristyl Stearate is a wax ester used primarily as an emollient and thickener in cosmetics and personal care products, providing slip, conditioning properties, and a smooth texture in creams, lotions, lip products, and hair care formulations. It also serves as a base wax and texture-enhancing additive in cosmetic bases and some cleansing products. In industrial contexts, it acts as a lubricant and slip agent in polymer processing, coatings, and inks, aiding processing and improving surface feel. It can function as a waxy additive in household polishes and wax-based products, contributing to gloss and form. Overall, it is typically used as a conditioning/emollient ester with applications constrained by formulation requirements and local regulations.
