  • Applications

    6-Methylheptadecane (CAS 26741-13-9) is a long-branched alkane (C18H38) used as a nonpolar solvent and carrier in many formulations, and can function as a fragrance fixative to extend and stabilize odor in perfumery; owing to its light oil-like character, it is also considered a base oil or emollient in cosmetics and personal care; in industrial contexts, it may serve as a solvent in coatings/inks and as a processing aid or lubricant in plastics and polymers; it may also appear as a component in cleaning or household product formulations.
