  • Applications

    13-Methylhentriacontane (CAS 33116-06-2) is a high-molecular-weight branched hydrocarbon primarily used as a waxy component in formulation blends. In cosmetics and personal care, it can function as a structuring agent and softening wax in wax-based products. In coatings and inks, it serves as a wax additive to improve slip, reduce blocking, and enhance gloss. In polymers and plastics processing, it can act as a processing aid and crystallinity modifier in wax blends or lubricant formulations. In industrial manufacturing, it is used as a base lubricant or lubricant additive for high-temperature or high-load applications. In household products, it is employed as a component of waxes and polishes to provide gloss and wear resistance.
