  • Applications

    Isostearyl Hydroxystearate is widely used as an emollient and conditioning agent in cosmetics and personal care, delivering a smooth skin feel and improving spreadability in creams, lotions, makeup, and lip products; it can also act as a solvent or carrier for fragrance oils and other actives in perfumery formulations; due to its lubricating and light nature, it is used to enhance slip and texture in coatings and other surface applications and may function as a plasticizer or lubricating additive in selected polymer systems; it may also appear in household products as an emollient component, subject to local regulations and formulation limits.
