  • Applications

    2-Methyldocosane (CAS 1560-81-2) is a high-boiling, branched aliphatic hydrocarbon typically used as a non-polar solvent and oil base. In cosmetics and personal care, it functions as an emollient and carrier oil for active ingredients and fragrance compounds. In perfumery, it provides a neutral solvent and diluent for fragrance formulations. In coatings and inks, it serves as a non-polar solvent to adjust rheology and drying characteristics. In polymer and plastics processing, it can act as a processing solvent or dilution medium; in cleaning formulations, it serves as a hydrocarbon solvent for degreasing. It may also be used as a base oil component in industrial lubricants. Subject to local regulations and formulation limits.
