  • Applications

    13,15-Triacontanedione is a long-chain diketone that is primarily encountered as an organic-synthesis intermediate and a potential building block for long-chain polymers and specialty chemicals. In industry, it may be used as a waxy component or processing aid in coatings, inks, and plastics formulations, contributing to texture, slip, and thermal properties. It can act as a high-molecular-weight lubricant or lubricant additive in industrial equipment. It may also be considered for cosmetic/personal-care applications as a wax-like emollient or thickener in certain formulations, subject to regulatory and formulation limits. Its use is typically evaluated on a case-by-case basis and governed by local regulations.
