Highly effective chelator for multivalent metal ions including Ca²⁺, Mg²⁺, Fe²⁺/³⁺, Cu²⁺, and Mn²⁺.
Excellent stability across a broad pH range (pH 2–12), ensuring consistent performance in diverse process conditions.
Biodegradable formulation compliant with OECD 301B standards, supporting sustainable industrial water treatment.
Low toxicity profile and non-corrosive to common process equipment materials such as stainless steel and carbon steel.
Compatible with oxidizing agents like hydrogen peroxide and chlorine-based disinfectants, enabling integration into bleaching and sanitization processes.
Textile processing — for sequestering hardness ions during dyeing, printing, and bleaching to prevent staining and improve color yield.
Pulp and paper manufacturing — to control transition metal catalysis in hydrogen peroxide bleaching and inhibit discoloration.
Industrial cleaning formulations — as a key ingredient in alkaline cleaners for boilers, heat exchangers, and CIP systems.
Electroplating and metal finishing — to stabilize bath chemistry and prevent precipitation of metal hydroxides.
Food & beverage processing — for equipment cleaning and sanitization where metal ion interference must be minimized.
