Use of Ethylenediaminetetraacetic acid tetra sodium salt (EDTA2Na) In industry:
EDTA is mainly used to sequester metal ions in aqueous solution. In the textile industry, it prevents metal ion impurities from modifying colours of dyed products. In the pulp and paper industry, this is used in "chlorine-free bleaching." In similar manner, EDTA is added to some food as a preservative or stabilizer to prevent catalytic oxidative decolouration, which is catalyzed by metal ions.In personal care products, it is added to cosmetics to improve their stability toward air. In soft drinks containing ascorbic acid .
