  • Applications

    Hydroxystearyl alcohol is a long-chain fatty alcohol with a hydroxyl group and is commonly used as a thickener and emollient in cosmetics and personal care formulations, helping improve texture, slip, and moisturized feel in creams, lotions, and hair care products. In polymer formulations, it often serves as a processing aid and lubricant, contributing waxy consistency and compatibility with other long-chain components. In coatings and inks, it can act as a wax modifier to adjust rheology and surface finish. Additionally, it may be used as a thickener and softening additive in household and industrial cleaners.
