  • Applications

    2-Ethoxyethyl stearate (CAS 72269-51-3) is used primarily as an emollient and solvent in cosmetics and personal care, providing a soft, smooth feel in creams and oils; it is also employed as a fragrance solvent and carrier in perfumery formulations; as a plasticizer for polymers and plastics (notably PVC) to improve softness and processing properties; in coatings and inks it serves as a lubricant and flow aid to improve coverage and surface smoothness; and in household and industrial cleaning formulations it can act as a solvent and processing aid to enhance solubility and formulation stability.
