Isostearyl lactate

Isostearyl lactate (CAS 42131-28-2 ), also known as isooctadecyl lactate, is an ester of isostearyl alcohol and lactic acid used primarily as an emollient and skin-conditioning agent in cosmetic formulations. Its branched-chain structure delivers a lightweight, non-greasy skin feel that positions it as a preferred alternative to heavier esters in leave-on and rinse-off products. In personal care, it functions as an emollient. It acts as a spreading agent in facial moisturizers, sunscreens, and color cosmetics, improving texture and skin adhesion without occlusive heaviness. Formulators also use it as a plasticizer and softener. This material is utilized in film-forming systems, including nail care and hair coating products. In lubricants and metalworking fluids, it contributes lubricity and acts as a coupling agent between components. It bridges polar and non-polar components effectively. Coatings and adhesive formulations incorporate it to improve flexibility and substrate wetting in specialty applications across various industrial sectors. Isostearyl lactate is supplied as a clear, pale liquid suitable for direct incorporation into oil phases or anhydrous systems. It is available in cosmetic-grade quality meeting personal care industry standards. Technical-grade material is also offered for industrial lubricant and coating applications. Packaging typically ranges from drums to intermediate bulk containers depending on specific volume requirements. Contact us for supply of Isostearyl lactate Request Quote
