  • Applications

    10-Methylnonadecane (CAS 56862-62-5) is a high-boiling, branched C20 alkane used primarily as a non-polar solvent and diluent in various industrial formulations. In coatings, inks, and adhesives, it functions as a solvent and processing aid. In cosmetics and personal care, it can serve as a carrier oil or base component where a lightweight, non-polar hydrocarbon is desirable. It may also be used in household and cleaning products as a formulation solvent or carrier. In polymer processing and plastics manufacturing, it can act as a diluent or processing aid for resin systems. For analytical work, it may be used as a hydrocarbon reference component in GC analyses. These applications are typical and subject to local regulations and formulation limits.
