Description

Trisodium EDTA (CAS 150-38-9 ) is a water-soluble chelating agent that binds and neutralizes metal ions in aqueous systems. It prevents them from interfering with formulation stability or process efficiency. It is the trisodium salt form of EDTA, offering a moderately alkaline pH profile. This suits applications where the tetrasodium form would be too basic for the specific chemical environment. In personal care and cosmetic formulations, it sequesters calcium and magnesium ions in hard water. This protects preservative systems and maintains product clarity in various consumer goods. Pharmaceutical manufacturers use it to stabilize liquid preparations by deactivating trace metals. This prevents metals from catalyzing oxidative degradation, ensuring the longevity of the final product. Water treatment operations rely on it to control scale formation and metal ion interference in process water. In textile and paper processing, it prevents metal-catalyzed discoloration during bleaching. This chemical improves batch consistency and end-product quality in industrial dyeing operations. It is supplied as a white crystalline powder or as an aqueous solution at 40–50% concentrations. Grades available include technical, food-grade, and pharmaceutical-grade material meeting USP and BP specifications. Bulk quantities are standard for industrial buyers and specialty use. Smaller packaging is also available for laboratory and specialty formulation requirements. This ensures that the product meets the diverse needs of both large-scale and niche manufacturers.
