  • Applications

    2-Ethylhexyl stearate (CAS number: 22047-49-0) is a lipophilic fatty ester widely used as an emollient and solvent in cosmetics and personal care products, improving spreadability and skin feel. It also serves as a plasticizer/softener in polymers and coatings, aiding flexibility in plastics and gloss in finishes. In perfumery, it acts as a fragrance carrier and solvent for essential oils, and in topical pharmaceuticals it serves as an inert excipient and vehicle to improve application and texture. It may also function as a processing aid or lubricant in coatings and inks.
