  • Applications

    Pyridoxine tripalmitate (CAS 4372-46-7) is a lipophilic ester of pyridoxine and is used primarily as a lipid-soluble source of vitamin B6 in formulated systems. In cosmetics and personal care, it is incorporated as a vitamin B6 source for skin and hair in creams and lipid-based bases, compatible with oil-rich matrices. In pharmaceutical/topical applications, it may serve as a lipophilic B6 delivery form for topical drug or nutraceutical formulations. In food processing/nutraceuticals, it can be evaluated as a lipid-based vitamin B6 source within oil-based carriers or fortified products. In agriculture/animal feed, it may be considered as a lipophilic vitamin B6 supplement for feeds or spray formulations.
