  • Applications

    Pentadecane, 6-methyl- (CAS 10105-38-1) is a branched C16 aliphatic hydrocarbon commonly used as a non-polar solvent and diluent across multiple sectors. In cosmetics and personal care, it serves as a lightweight carrier oil and base in formulations, helping to improve texture and feel. In coatings, inks and adhesives, it functions as a low-volatility solvent and processing aid. In household products and cleaners, it provides a hydrocarbon solvent to dissolve hydrophobic actives. In industrial manufacturing, it can be used as a lubricant component or base oil in metalworking fluids and as a dilution solvent in formulation.
