  • Applications

    Heneicosane, 11-decyl- is a long-chain paraffinic hydrocarbon primarily used as a wax component and a nonpolar carrier in diverse formulations. Real-world applications include: cosmetics/personal care as a waxy thickener and texture enhancer; perfumery/fragrance as a fragrance carrier to modulate volatility and extend scent; household products and wax polish formulations to impart gloss and slip; coatings/inks as a wax additive to adjust flow, gloss, and slip; and from a polymer/plastics perspective as a slip agent or processing aid to improve processing characteristics and surface properties. Use may vary with formulation and is subject to local regulations and formulation limits.
