  • Applications

    Ethyl dotriacontanoate (CAS 29030-82-8) is a high‑molecular‑weight fatty acid ester used primarily as an emollient and conditioning ingredient in cosmetics and personal care products such as creams, lotions, and hair care formulations. Its low volatility and suitable viscosity also make it a component in waxy or plastic formulations and in coatings where it can impart gloss and texture. In polymer and coating applications, it can act as a plasticizer or lubricant for wax‑based systems and as a processing aid in certain formulations. Additionally, due to its durability and scent‑lean profile, it may be evaluated as a fragrance ingredient or fixative in perfumery and fragrance products, and may serve as a carrier or solvent in household cleaners and surface care formulations, subject to local regulations and formulation limits.
