  • Applications

    Endothal-disodium (CAS 33054-59-0) is an industrially oriented chemical that may find use as an intermediate and processing aid with several practical applications. In fragrance systems, it may act as a fixative or odorant component; in cosmetics/personal care, it may serve as a stabilizer or functional additive in formulations such as perfumes, shampoos, or moisturizers. In household cleaning, it can function as a chelating agent or formulation aid to enhance cleaning efficiency. In coatings/inks and in polymers/plastics, it may be used to improve formulation stability, compatibility, and processing. Its use is subject to local regulations and formulation limits.
