EDTA Tetrasodium Salt

EDTA Tetrasodium Salt is mainly used to sequester metal ions in aqueous solution. In the textile industry, it prevents metal ion impurities from modifying colors of dyed products.In a similar manner, EDTA is added to some food as a preservative or stabilizer to prevent catalytic oxidative decoloration, which is catalyzed by metal ions. The reduction of water hardness in laundry applications and the dissolution of scale in boilers both rely on EDTA and related complexants to bind Ca2 , Mg2 , as well as other metal ions. In shampoos, cleaners and other personal care products EDTA salts are used as a sequestering agent to improve their stability in air. EDTA tetrasodium salt is predominatly used in agriculture, water treatment, pulp and paper industries and also used in the manufacture of cleaners and detergents.
