Description

Tetrasodium glutamate diacetate , also identified by CAS 51981-21-6 , is a biodegradable chelating agent derived from glutamic acid. It binds and sequesters metal ions such as calcium, magnesium, iron, and manganese to prevent interference in formulations. Buyers in personal care, cleaning, and water treatment source it as a more sustainable alternative to EDTA and NTA. In personal care formulations, it stabilizes product performance by deactivating trace metals that would otherwise degrade active ingredients. Industrial and institutional cleaning products use it to boost surfactant efficiency and prevent mineral scale redeposition on surfaces. Water treatment applications rely on it to control metal ion concentrations and inhibit scale formation. In food-contact and agricultural cleaning, its biodegradability profile supports compliance with stricter environmental regulations. It maintains high chelation performance while meeting modern ecological standards for industrial chemical use. The product is typically supplied as a liquid solution at 47% active content, which is the standard commercial concentration. Technical and industrial grades are the most common market forms available for bulk procurement. Specifications vary by supplier, and buyers should confirm active content, pH range, and impurity limits. This ensures the material meets specific formulation or process requirements for high-performance industrial applications. Contact us for supply of Tetrasodium glutamate diacetate Request Quote
