  • Applications

    1-Octacosanol (CAS 557-61-9) is primarily used as an emollient and moisturizing ingredient in cosmetics and personal care, helping to soften the skin and improve feel upon application. In polymers and plastics, it often acts as a lubricant and processing aid, improving processability and reducing wear in plastic and rubber systems. In coatings, inks, and polishes, it is used as a wax-like component to improve gloss, water resistance, and surface stability. In adhesives and sealants, it can function as a wax additive to adjust processing characteristics and open time. In industrial lubricants and processing fluids, it can serve as a lubricant additive to reduce friction. In cleaning and polishing formulations, it may be used as a wax component to enhance shine and slip.
