Tetrasodium edetate dihydrate

Tetrasodium edetate dihydrate (CAS 10378-23-1 ), commercially known as EDTA-4Na, is a fully neutralized sodium salt of EDTA supplied in hydrated form. It functions as a chelating and sequestering agent, binding metal ions such as calcium and magnesium. By binding iron and copper, it prevents these metal ions from interfering with formulations, processes, or finished products. In personal care and cosmetics, EDTA-4Na stabilizes formulations by deactivating trace metals that would otherwise degrade preservative systems. This prevents rancidity and ensures long-term product integrity for consumer use. Water treatment operations use it to sequester hardness ions and control scale formation in industrial circuits, improving overall system efficiency and reducing maintenance costs. Textile and leather processing relies on it to prevent metal-catalyzed oxidation during bleaching and dyeing. This protects color consistency and fabric integrity throughout the manufacturing cycle, ensuring high-quality results for industrial textile producers. In food-compatible applications, it functions as a sequestrant to maintain product stability and extend shelf life where metal contamination is a processing risk. This makes it a versatile additive for various sensitive manufacturing environments. Tetrasodium edetate dihydrate is supplied as a white crystalline powder or granules. It is available in technical grade for industrial applications and food-grade specifications meeting FCC and BP standards for high purity requirements. Packaging ranges from small bags to bulk quantities, with concentration typically expressed on a dihydrate basis. This ensures accurate dosing and handling for large-scale chemical operations and specialized laboratory applications alike. Contact us for supply of Tetrasodium edetate dihydrate Request Quote
