  • Applications

    Campesteryl stearate (CAS 55064-20-5) is primarily used as a waxy sterol ester in cosmetics and personal care, where it acts as an emollient and structuring/thickening agent in creams, lotions, and makeup formulations (including lipstick and nail products). It is also employed as a rheology modifier and slip component in coatings, inks, and polishing formulations, helping texture, gloss, and glide. In polymer and plastics processing, it can serve as a wax-based processing aid or softener to adjust crystallinity and compatibility with lipid-like ingredients. In household products, it may function as a waxy thickener and conditioning agent in cleaners and surface care formulations. Note: use is subject to local regulations and formulation limits.
