  • Applications

    4-Methyloctacosane (CAS 73189-31-8) is a long-chain alkane that may be used as a waxy ingredient in cosmetics and personal care products, providing slip and acting as a thickening or occlusive component; it may function as a fragrance fixative in perfumery due to its low volatility; it can be used as a wax additive in coatings and inks to improve slip, gloss, and water resistance; it may serve as a processing aid or lubricant in polymer manufacturing; and it can be found as a wax component in household polishes, cleaners, and automotive wax formulations. Its use is subject to local regulations and formulation limits.
