Sodium Carbonate - 497-19-8

Key Functions: Food Contact & Additives, Industrial / Manufacturing, Pesticides & Biocides, Pharmaceuticals, Textile Applications

Sodium carbonate is used in the decontamination of radioactive surfaces, glass production, detergent formulation, photography, adjustment of water pH, textile bleaching, and as a fungicide, cosmetic ingredient, food additive, and alkalizing agent in pharmaceuticals (HSDB 2018). It is also used as a builder in water softening formulations and is used as an additive in various cleaning products (HERA 2005). It is produced via processing of natural sodium carbonate bearing deposits, from lake brines or sea water via electrolysis, or by the ammonia soda (Solvay) process (HSDB 2018). Sodium carbonate is considered Generally Recognized As Safe (GRAS) by the United States Food and Drug Administration (U.S. FDA) (U.S. FDA 2021). In biology, carbonate is a component of the bicarbonate buffer system in blood and interstitial fluid of vertebrates (UNEP 2002).
