Applications

1. Detergents & Cleaning Formulations

• Softens hard water by sequestering Ca²⁺/Mg²⁺ ions (0.5-3% w/w)

• Stabilizes bleach and enzymes in cold-water laundry/dishwasher detergents

• Prevents scale deposition in industrial cleaners

2. Water Treatment

• Prevents CaCO₃/Fe(OH)₃ scaling in cooling towers/RO membranes (5-50 ppm)

• Chelates heavy metals (Cu²⁺, Zn²⁺) in wastewater to meet discharge limits

3. Pulp & Paper Bleaching

• Protects H₂O₂ from catalytic decomposition by Fe³⁺/Mn²⁺

• Enhances brightness yield by 2-4 points in recycled paper deinking

4. Agrochemicals

• Delivers Fe/Zn/Mn micronutrients in foliar fertilizers

• Prevents nozzle clogging in glyphosate-based herbicides

5. Personal Care

• Prevents rancidity in shampoos/creams by chelating pro-oxidant metals

• Reduces irritation in surfactant systems (ECOCERT/COSMOS certified)

6. Metal Surface Treatment

• Removes metal oxides in alkaline derusting formulations (pH 9-12)

• Stabilizes electrolyte composition in Ni/Cu electroplating baths

6. Packaging & Storage

   • Liquid: PE drums (25L/200L). Store at 5-40°C; avoid freezing.

   • Powder: 25 kg PE-lined bags. Ambient dry storage; 24-month shelf life.

7. Comparable Chelators

   Product	Key Differentiation
   EDTA	Superior chelation but persistent in environment
   GLDA	Comparable biodegradability; higher raw material cost
