As global industries pivot toward "Green Chemistry," the demand for high-performance yet environmentally responsible sequestering agents has never been higher. Tetrasodium Aspartate Diacetate (ASDA-Na4) is emerging as a premier biodegradable alternative to traditional phosphonates and EDTA, offering a unique balance of powerful chelation and rapid environmental breakdown.
ASDA-Na4 is a bio-based aminopolycarboxylate chelating agent derived from L-aspartic acid. Unlike conventional persistent chelators, ASDA is designed to be fully biodegradable, ensuring that industrial processes do not contribute to long-term heavy metal accumulation in water systems.

Its molecular structure provides multiple coordination sites (carboxyl and amine groups), allowing it to form highly stable, water-soluble complexes with a wide range of metal ions, including Calcium (Ca2+), Magnesium (Mg2+), and Iron (Fe3+).
In the European detergent sector, ASDA-Na4 is a vital "green" builder. It effectively softens hard water, prevents mineral scale buildup on surfaces, and enhances the performance of surfactants in both laundry and automatic dishwashing detergents (ADWD).
Benefit: Excellent stability at high pH and high temperatures.
ASDA-Na4 serves as a superior carrier for micronutrients in foliar and soil fertilizers.
Benefit: It increases the bioavailability of essential minerals like Zinc and Copper without leaving harmful residues in the soil, aligning with the EU’s "Farm to Fork" strategy for eco-friendly farming.
As a scale inhibitor and stabilizer in cooling towers and boiler systems, ASDA-Na4 prevents the precipitation of carbonates and sulfates, maintaining heat transfer efficiency while reducing the environmental footprint of blowdown water.
Biodegradability: Meets OECD 301B standards, degrading significantly faster than EDTA or NTA.
Safety Profile: Non-toxic, non-irritating, and free from phosphorus and nitrogen-related eutrophication risks.
High Chelation Value: Comparable efficiency to EDTA in controlling transition metal ions across a wide pH range.
