  • Applications

    Heptyl palmitate (CAS number: 26718-83-2) is a non-volatile fatty ester that is commonly used as an emollient and oil-like solvent in cosmetics and personal care, providing slip and skin-conditioning properties and serving as a carrier for fragrances and active ingredients; in perfumery/fragrance applications it can act as a medium to dissolve and blend fragrance oils; as an excipient or vehicle in pharmaceutical topical formulations; as a processing aid or lightweight lubricant in industrial manufacturing and polymer/coatings applications; and in coatings and inks it may function as a plasticizer or slip agent to improve flow and texture.
