  • Applications

    Stearyl Behenate (CAS 24271-12-3) is a high-molecular wax ester used primarily in cosmetics and personal care as an emollient and thickener for creams, lotions, and makeup products; due to its high-molecular structure, it is also employed as a lubricant and texturing aid to improve skin feel and emulsion stability; in polymer and plastics processing it can serve as a processing aid and slip lubricant to modify rheology; in coatings and inks it is used as a wax additive to enhance gloss and flow properties; and in household cleaning and care products it may be included as a softening, lubricating additive contributing to smoothness and gloss. Subject to local regulations and formulation limits.
