Used as an emollient in cosmetics and personal care products, ethyl stearate helps improve texture and spreadability in creams, lotions, and makeup. It provides a smooth, non-greasy feel on the skin by forming a protective barrier that reduces moisture loss. In pharmaceuticals, it serves as a solubilizer and carrier for active ingredients in topical formulations. It is also used in the fragrance industry as a solvent and fixative to stabilize and prolong the release of aromatic compounds. Additionally, it finds application in industrial lubricants and plasticizers, where it acts as a stabilizer and processing aid in polymers and coatings.
