  • Applications

    Hexanoic acid, 2-ethyl-, octadecyl ester (CAS 59130-70-0) is a high-molecular-weight, long-chain fatty acid ester commonly used as an emollient and waxy conditioning agent in cosmetics and personal care. It also serves as a lipophilic lubricant or processing aid in polymers and plastics, aiding slip and processing rheology. In coatings and inks, it acts as a waxy additive to improve gloss, slip, and water resistance. In household products, it can function as a conditioning or lubricating component in formulations for fabrics, cleaners, and surface care. It is used as an additive in adhesives and sealants to modify tack, film formation, and durability, and may be present as a processing aid or lubricant in industrial lubricant formulations.
