Isopropyl Palmitate (CAS 142-91-6) is the isopropyl ester of palmitic acid, a colorless neat liquid emollient that provides high spreadability and a non-greasy skin feel without clogging pores, and is used in personal care products and topical pharmaceutical delivery systems. The product serves as an effective solubilizer for active ingredients, vitamins, and fragrances in topical pharmaceutical delivery systems. It is characterized by low viscosity and high oxidative stability, ensuring consistent performance in anhydrous formulations. As a highly stable Technical Grade ester, it acts as a conditioning agent that enhances the moisture barrier of the skin. It is widely preferred for its non-irritating profile and compatibility with most cosmetic surfactants and oils.
