  • Applications

    4-Methylheptadecane (CAS 26429-11-8) is a long-chain branched alkane used as a nonpolar solvent and diluent in a range of industrial and cosmetic formulations. In perfumery and personal care, it may act as a carrier and fragrance fixative to modulate evaporation and scent longevity. It is also considered as a hydrocarbon solvent component for coatings and inks, and can function as a processing aid in industrial manufacturing where high-boiling hydrocarbons are required. In cleaning products and household formulations, it may help dissolve hydrophobic constituents due to its nonpolar nature. Additionally, it can serve as a processing aid or lubricity-enhancing additive in polymer and plastics processing. Subject to local regulations and formulation limits.
