  • Applications

    PEG-3 Dipalmitate (CAS 68818-45-1) is primarily used as an emollient and skin conditioning agent in cosmetics and personal care products; as a nonionic surfactant and emulsifier in cosmetic formulations and some cleaning products; as a lubricating or slip additive in coatings, inks, and polishes; as a plasticizer or softening component in polymer and plastic formulations; and can serve as an intermediate in the synthesis of other ester-based cosmetic ingredients.
