Tetrasodium iminodisuccinate

Tetrasodium iminodisuccinate (CAS 144538-83-0), commercially known as IDS tetrasodium salt, is a biodegradable chelating agent derived from aspartic acid.

Where is Tetrasodium iminodisuccinate used?

• Water treatment: scale and corrosion control in cooling towers, boilers and process water systems
• Personal care: stabilises emulsions and protects actives from metal ion interference in rinse-off and leave-on products
• Textile and leather: prevents metal-induced dye inconsistencies during dyeing and finishing
• Agricultural formulations: micronutrient carrier that improves iron and manganese bioavailability in foliar sprays and fertigation
• It sequesters calcium, magnesium, iron and other metal ions across a broad pH range.

Good to know: Particularly effective where conventional chelants face discharge restrictions. Buyers should confirm active content, pH and biodegradability certification.

Commercial specifications

• Aqueous solution, typically 30–40% active content
• Technical and industrial grades
• Formulation-grade material for personal care and agricultural applications
