  • Applications

    Tetrasodium Iminodisuccinate (CAS 144538-83-0) is a biodegradable chelating agent used across several real-world applications: as a metal-sequestering additive in household and industrial cleaners to improve cleaning performance and minimize scale; as a chelating agent in cosmetics and personal care formulations to stabilize systems and help preserve clarity and color; in industrial manufacturing and metal finishing, it serves to complex metal ions and control corrosion and scale formation in processing streams; in coatings, inks, and textile finishing, it supports pigment dispersion and stability by reducing interference from trace metals; and in water treatment and process-water management, it helps inhibit precipitation and metal-catalyzed reactions, extending equipment life and process reliability.
