  • Applications

    Ethylhexyl Hydroxystearate (CAS 29710-25-6) is primarily used as an emollient and skin-conditioning agent in cosmetics and personal care, providing a light, non-greasy feel when applied to the skin. It also serves as a solvent/carrier for fragrances and active ingredients in fragrance formulations and skincare products. In the polymer sector it is considered a processing aid with applications as a plasticizer or lubricant in certain polymer systems, and it may be incorporated into coatings and inks to modify slip and texture. Its use and limits depend on local regulations and formulation constraints.
