  • Applications

    Disodium Malyl Tyrosinate (CAS 126139-79-5) is primarily considered a chelating/sequestrant and functional additive in a range of formulations; in cosmetics and personal care it can help stabilize emulsions and protect actives from metal-catalyzed degradation; in cleaning and household products it can act as a metal-binding agent to improve cleaning efficiency; in industrial manufacturing it may serve as a processing aid or stabilizer, and in polymers, coatings, inks, and plastics it can function as a dispersant or pigment stabilizer; it may also be evaluated for use in electronics-related cleaning or agricultural formulations as a mild chelating/buffering component, depending on local regulations and formulation limits.
