Tetrasodium iminodisuccinate

Tetrasodium iminodisuccinate (CAS 144538-83-0), commercially known as IDS tetrasodium salt, is a biodegradable chelating agent derived from aspartic acid. It sequesters calcium, magnesium, iron, and other metal ions across a broad pH range.

This versatile chemical prevents scale formation, precipitation, and metal-catalyzed degradation in industrial and consumer formulations. In water treatment, it controls scale and corrosion in cooling towers, boilers, and process water systems.

It is particularly effective where conventional chelants face discharge restrictions. Personal care formulators use it to stabilize emulsions and protect active ingredients from metal ion interference in rinse-off and leave-on products.

Textile and leather processors rely on it to prevent metal-induced dye inconsistencies during dyeing and finishing operations. In agricultural formulations, it functions as a micronutrient carrier for various applications.

It improves the bioavailability of iron and manganese in foliar sprays and fertigation systems. Tetrasodium iminodisuccinate is supplied as an aqueous solution, typically at 30–40% active content, and in dry powder form.

Standard commercial grades meet technical and industrial specifications. Formulation-grade material is available for personal care and agricultural applications, ensuring high performance across diverse sectors.

Buyers should confirm active content, pH, and biodegradability certification when evaluating supply options. This ensures the material meets specific regulatory and performance requirements for the intended industrial use.
