  • Applications

    9-Methylnonadecane, CAS 13287-24-6, is a high-boiling branched long-chain alkane typically used as a non-polar solvent and diluent in a range of formulations. In perfumery it can function as a fragrance base or carrier and may contribute to fixation by reducing volatility; in cosmetics and personal care it acts as a light, non-volatile emollient carrier oil; in household products it is used as a hydrocarbon solvent or diluent in cleaners and polishes; in polymers and plastics processing it can serve as a processing oil or lubricant additive to improve flow and compatibility; in coatings and inks it is used as a solvent or diluent to adjust viscosity and drying characteristics; in broader industrial manufacturing it can be employed as a general non-polar processing oil or carrier within formulated products, subject to formulation limits and local regulations.
