Highly effective chelator for multivalent metal ions including Ca²⁺, Mg²⁺, Fe³⁺, Cu²⁺, and Mn²⁺ under neutral to alkaline pH conditions.
Excellent thermal and hydrolytic stability, maintaining performance in demanding industrial process environments.
Low toxicity profile and favorable environmental compatibility compared to alternative phosphonate or NTA-based chelants.
Soluble in water across a broad pH range (pH 2–12), enabling easy integration into aqueous formulations.
Non-corrosive to common process equipment materials such as stainless steel, carbon steel, and copper alloys.
Textile processing — for metal ion sequestration in dyeing, bleaching, and printing baths.
Industrial cleaning formulations — to prevent scale formation and enhance detergent efficacy in hard water.
Personal care products — as a stabilizer for peroxides, enzymes, and colorants in shampoos and cosmetics.
Water treatment in cooling towers and boiler systems — for controlling metal-catalyzed degradation and deposition.
Paper and pulp manufacturing — to inhibit transition metal interference during hydrogen peroxide bleaching.
