TetraSodium Iminodisuccinate (IDS-Na4): The Eco-Fertile Future of Chelation Starts Here
Unlock next-generation performance with TetraSodium Iminodisuccinate (IDS-Na4), the 100 % biodegradable, REACH-registered chelating agent that replaces EDTA, NTA and phosphates without compromising results.
What is IDS-Na₄?
TetraSodium Iminodisuccinate (CAS 144538-83-0) is the tetrasodium salt of iminodisuccinic acid—an amino-polycarboxylate that forms highly stable water-soluble complexes with Ca²⁺, Mg²⁺, Fe³⁺, Cu²⁺, Zn²⁺ and other multivalent metal ions. Unlike EDTA, IDS-Na₄ biodegrades into innocuous by-products within 28 days (OECD 301 E), making it the first chelate to earn the EU “Readily Biodegradable” label.
Key Benefits at a Glance
• Eco-Friendly Chelate: Phosphate-free, NTA-free, non-toxic to aquatic life—perfect for green labels such as Safer Choice & EU Ecolabel.
• Superior Binding Constants: log K stability values rival EDTA, ensuring consistent sequestration and micronutrient delivery.
• Wide pH Range: Effective from pH 3–12; ideal for acidic fertilizers, alkaline cleaners, and boiler water treatment.
• Low Corrosion Profile: Reduces metal surface attack compared to phosphates or citrates.
• Regulatory Ready: REACH full-registration, TSCA listed, Kosher & Halal certified.

High-Impact Applications
-
Agriculture & Fertigation
• Micronutrient chelation in foliar and soil-applied fertilizers (Fe-IDS, Zn-IDS, Cu-IDS).
• Prevents scale formation in drip irrigation, boosting water-use efficiency by up to 18 %.
• Compatible with polyphosphate and orthophosphate blends. -
Industrial & Institutional Cleaners
• Replaces phosphates in hard-surface, vehicle and dairy cleaners without leaving residues.
• Boosts chlorine stability in hypochlorite formulations—perfect for hospital sanitation. -
Water Treatment & Desalination
• Sequesters hardness ions to reduce RO membrane fouling and extend run times.
• Meets stringent discharge limits for heavy-metal complexes (< 0.1 ppm). -
Pulp & Paper
• Controls transition-metal catalyzed peroxide decomposition, increasing brightness and yield.
