  • Applications

    Aluminum Lactate (CAS 18917-91-4) is used as a metal salt that can function as a buffering and chelating agent in formulations; in cosmetics and personal care it may serve as a pH adjuster and metal-ion sequestrant to improve stability and performance. It is also considered for cleaning and household products as a chelating additive to reduce mineral hardness and enhance surfactant efficacy. In coatings and inks, it may act as a processing aid, crosslinking or curing modifier in certain resin systems. In industrial manufacturing and polymers/plastics, it is often evaluated as a stabilizer or catalyst/curing aid for specific polymer formulations. In textiles, it can serve as a mordant or dye fixer, and in leather processing it may participate in tanning formulations. Its use is formulation- and regulation-dependent.
