  • Applications

    Chemical name: 15-Nonacosanol; CAS number: 2764-81-0. This long-chain fatty alcohol is used as a waxy ingredient in cosmetics and personal care products to impart slip, act as an emollient, and aid in thickening and texture development. In perfumery, it may serve as a fragrance carrier or, in certain formulations, a fixative due to its waxy, low-volatility character. In polymers and plastics processing, it can function as a processing aid or lubricant and as a wax component to adjust rheology. In coatings and inks, it can be added as a wax-like additive to improve slip and gloss. In industrial manufacturing, it may act as a processing aid or lubricant in various production steps. It can also be considered as an intermediate for the synthesis of fragrance esters, under appropriate formulation conditions.
