  • Applications

    Hentriacontane-14,16-dione (CAS 24724-84-3) is a long-chain diketone that is commonly considered an intermediate in organic synthesis and may also be used as a wax-like component in cosmetic and personal care formulations. In cosmetics and personal care, it can function as a waxy ingredient or filler to adjust texture and slip. In the plastics and rubber industries, it may serve as a processing aid or to improve compatibility with oil-based matrices. In coatings and inks, it can act as a wax additive to enhance processing characteristics such as slip and gloss. In chemical processing and manufacturing, it may be used as a precursor to related thermally stable or chemically resistant compounds, depending on local regulations and formulation limits.
