  • Applications

    Butoxyethyl stearate (CAS 109-38-6) is commonly used in cosmetics and personal care as an emollient and texture-enhancing ingredient, providing slip and a soft, non-greasy feel in products such as creams, lotions, and makeup bases. It also serves as a plasticizer and processing aid in industrial polymer and coating formulations, helping to improve flexibility and handling during processing. In coatings and inks, it functions as a lubricating additive that improves flow, leveling, and gloss, reducing surface tack. In broader industrial manufacturing, it can act as a solvent or co-solvent component in formulated products where fatty ester compatibility is required. Subject to local regulations and formulation limits.
