Highly effective chelator for multivalent metal ions including Ca²⁺, Mg²⁺, Fe²⁺/Fe³⁺, Cu²⁺, and Mn²⁺ under neutral to alkaline conditions.
Excellent biodegradability (OECD 301D compliant), supporting sustainable process design and regulatory compliance.
Superior thermal and pH stability compared to traditional EDTA-based chelants, maintaining performance up to pH 11 and at elevated temperatures.
Low ecotoxicity profile with favorable aquatic toxicity data (e.g., high EC50 values for Daphnia magna and algae).
Compatible with anionic, nonionic, and cationic surfactants—ideal for complex formulation systems.
Detergents and household cleaning products, especially in automatic dishwashing detergents and laundry formulations.
Industrial cleaning agents for metal surface treatment, boiler water conditioning, and CIP (clean-in-place) systems.
Textile processing auxiliaries, including dyeing, bleaching, and finishing baths to prevent metal-induced color defects.
Personal care products such as shampoos, liquid soaps, and cosmetics requiring water hardness control and ingredient stabilization.
Water treatment in cooling towers and membrane filtration systems to inhibit scale formation and metal-catalyzed oxidation.
