  • Applications

    7-Methylnonadecane, CAS 57160-74-4, is a long-chain branched alkane commonly used as a high-boiling hydrocarbon solvent and carrier oil in a range of applications; in cosmetics and personal care it can serve as a carrier for active ingredients and as a moisture-retaining oil; in perfumery it can function as a fragrance diluent and/or fixative to help extend scent release; in coatings, inks, and cleaning formulations it may act as a solvent/diluent and flow modifier; in polymer and plastics processing it can serve as a processing aid or a lightweight lubricant; and as a component of hydrocarbon solvent blends for industrial manufacturing, subject to formulation limits and local regulations.
