The New Era of Green Chelation

 

Amid increasingly stringent environmental regulations and a global consensus toward green chemistry, traditional chelating agents face significant challenges due to their environmental persistence and poor biodegradability. Tetrasodium Iminodisuccinate (IDS-4Na or IDS), a novel green and biodegradable chelator, is revolutionizing industries such as cleaning, textiles, water treatment, and agriculture with its exceptional performance and eco-friendly properties.

I. What is Tetrasodium Iminodisuccinate? Decoding Its Green Core

Tetrasodium Iminodisuccinate (CAS No.: 144538-83-0) is an eco-friendly chelating agent derived from natural amino acids. Its molecular formula is C₈H₇NO₈Na₄ (MW: 337.1), and it effectively replaces conventional chelators like EDTA, DTPA, and NTA, significantly reducing environmental impact.

Key Features & Technical Specifications:

• Eco-Friendliness:

  • Readily biodegradable (>60% per OECD 301B)

  • Non-toxic to aquatic ecosystems, phosphorus-free (prevents eutrophication)

• High Efficiency:

  • Superior chelation of Ca²⁺, Mg²⁺, Zn²⁺, Fe²⁺/³⁺, Cu²⁺, and Mn²⁺

  • Outperforms EDTA in binding capacity under alkaline conditions

• Stability:

  • Effective across a broad pH range (including strong acids/alkalis)

  • Excellent peroxide stabilizer for bleach-based applications

• Physical Properties:

  • Colorless to pale yellow liquid or white powder

  • Liquid form: ≥40% solid content, density ≥1.30 g/cm³ (20°C), pH 10.3–11.5 (1% solution)

II. Applications: How IDS-4Na Drives Green Transformation

1. Industrial Cleaning & Detergents

• Removes iron sulfide scales and hard water deposits in metal/pipe/glass cleaning

• Enh surfactant efficacy in household detergents while ensuring product safety

2. Textile dyeing & Paper Bleaching

• Prevents metal-ion-induced dye degradation for brighter, uniform coloration

• Stabilizes H₂O₂ in pulp bleaching, reduces silicate scaling, and protects equipment

3. Water Treatment

• Acts as a scale inhibitor and softener in circulating water systems

• Complies with strict wastewater discharge regulations

4. Agriculture – Micro-Nutrient Delivery

• Chelates Ca, Mg, Zn, Cu, Fe, Mn for improved plant absorption

• Used in foliar fertilizers, water-soluble fertilizers, and NPK compounds to boost efficiency

5. Emerging Applications

• Cosmetics: Mitigates heavy metal-induced oxidation, reducing skin irritation

• Electronics: Removes metal impurities from semiconductor/glass substrates

• Soil Remediation: Extracts heavy metals with easier separation/recovery

• Product Preservation: Extends shelf life by chelation of catalytic metals
