Product Usage

EDTA tetrasodium salt trihydrate is a highly effective chelating agent renowned for its ability to sequester polyvalent metal ions. Its primary application is in industrial cleaning and water treatment, where it softens water by binding with calcium and magnesium, preventing scale formation. In the textile and paper industries, it stabilizes bleaching processes and prevents metal-induced discoloration. Furthermore, it is a crucial component in personal care and cosmetics, acting as a preservative booster and stabilizer. It also finds significant use in the food and beverage industry to prevent oxidation and in agriculture as a carrier for micronutrient fertilizers.
