  • Applications

    Arachidyl stearate (CAS 22413-02-1) is a high-molecular wax ester commonly used in cosmetics and personal care as an emollient and thickener, providing slip, moisturization, and a smooth, non-greasy feel in creams, lotions, lip balms, and hair care products. It also acts as a structuring and conditioning agent in solid or semi-solid bases, helping improve texture stability and glide. Beyond cosmetics, the ester can be used as a wax additive in coatings, inks, and plastics to modify rheology, gloss, and hardness, and may serve as a lubricating or slip agent in industrial formulations and adhesives. In some formulations, it serves as a carrier for fragrances or active ingredients, or as a specialized component in lubricant systems, with usage dictated by formulation goals and local regulations.
