Highly effective sequestration of multivalent metal ions including Ca²⁺, Mg²⁺, Fe³⁺, and Cu²⁺ across a broad pH range (pH 4–12).
Excellent thermal and hydrolytic stability, maintaining chelating performance under demanding process conditions.
Low toxicity profile and readily biodegradable, supporting compliance with stringent environmental and regulatory standards (e.g., OECD 301B).
Non-corrosive to common industrial equipment materials, reducing maintenance requirements and extending system lifespan.
Compatible with oxidizing agents, surfactants, and enzymes—ideal for formulated cleaning and personal care products.
Industrial cleaning formulations—including alkaline cleaners, CIP (clean-in-place) solutions, and detergent concentrates.
Textile processing auxiliaries for dyeing, bleaching, and finishing where metal ion interference must be minimized.
Water treatment in cooling towers and boiler systems to prevent scale formation and metal-catalyzed oxidation.
Personal care products such as shampoos, liquid soaps, and color cosmetics to enhance stability and clarity.
Food-contact surface cleaners approved for use in food & beverage manufacturing facilities (per FDA 21 CFR §178.3740).
