  • Applications

    Isopropyl Arachidate (CAS 26718-90-1) is the ester of arachidic acid with isopropanol. In cosmetic and personal care formulations it is commonly used as an emollient and texture enhancer, providing slip and a light feel on the skin; it also serves as a solvent and carrier for fragrance oils and active ingredients in perfumery and color cosmetics; in polymer and coating systems it can function as a plasticizer or processing aid to improve flexibility and handling; it is sometimes evaluated as a component in cleaning formulations as a hydrophobic solvent or solubilizer; it may also be used as an intermediate in the synthesis of cosmetic ingredients or specialty esters.
