  • Applications

    Isohexacosanol (CAS 68444-33-7) is a long-chain fatty alcohol with a waxy, oily character and has practical applications across several industries such as: acting as an emollient in cosmetics and personal care; serving as a thickener and viscosity-building component in cosmetic formulations; functioning as a waxy component in coatings and inks to improve slip, gloss, and surface stability; used as a lubricity additive and processing aid in polymer manufacturing to reduce friction and improve flow; and used as a lubricant/additive in industrial lubricants and greases.
