  • Applications

    10-Methylicosane (CAS 54833-23-7) is a long-chain hydrocarbon encountered in complex hydrocarbon blends. In industry, it may be used as a non-polar solvent and carrier for high-boiling formulations; it can serve as a waxy component in cosmetics and personal care products as an emollient and thickener; in coatings and inks, it is used as a wax additive to improve slip, gloss, and water resistance; in industrial manufacturing and polymer processing, it can function as a processing aid or lubricant for molds and equipment; in fragrance formulations, it may be used as a non-volatile diluent or carrier for odorants; and in analytical work, it is often used as a reference or calibration material for GC analysis of long-chain hydrocarbons. Subject to local regulations and formulation limits.
