  • Applications

    4-Methylnonadecane (CAS 25117-27-5) is a branched high-molecular-weight alkane commonly used as a fragrance ingredient and fixative in perfumery due to its low volatility; it may serve as a fragrance component or fixative in perfumes and cosmetic formulations. It can also function as a non-polar solvent or carrier in cosmetics and personal care products, and may be employed in household products to influence texture or carry fragrance. In coatings and inks, it can act as a non-polar solvent or processing aid, while in industrial manufacturing it may serve as a lubricant or processing solvent; subject to local regulations and formulation limits.
