  • Applications

    Tripalmitolein (CAS 20246-55-3) is the triglyceride of palmitoleic acid. It is primarily used as an emollient and conditioning oil in cosmetics and personal care, delivering a soft feel on skin and hair. In perfumery, it is commonly used as a fragrance carrier oil to dissolve and distribute fragrance ingredients. As a lipid-based excipient, it is often evaluated for use as a carrier lipid in pharmaceutical and nutraceutical formulations. It may also serve as a processing oil or additive in specialty industrial applications, such as polymer coatings or other coating formulations, where its unsaturated fatty acid content can influence properties. Applications are subject to local regulations and formulation limits.
