  • Applications

    5-Methylpentadecane is a branched long-chain alkane that primarily functions as a non-polar solvent and carrier fluid in various formulations. In cosmetics and personal care, it can serve as a lightweight solvent and lubrication component to improve texture and slip in creams and fragrance preparations. In household products and cleaners, it provides a non-polar diluent for oils and greases in surface cleaners and polishes. In paints, coatings, and inks, it is used as a hydrocarbon diluent or processing solvent to adjust viscosity and drying characteristics. In industrial manufacturing and polymer processing, it may act as a processing solvent or solvent-based component in polymer formulations and as part of lubricant base oils. Its use is typically formulation- and regulation-dependent.
