HS Code : 28151110 Brief Description: ; Caustic soda (sodium hydroxide) is a versatile alkali. It is a white solid ionic compound consisting of sodium cations Na+ and hydroxide anions OHâ??. Sodium hydroxide is a highly caustic base and alkali that decomposes proteins at ordinary ambient temperatures and may cause severe chemical burns. Main Uses/ Industry : " Caustic soda reacts with bauxite to dissolve aluminium-bearing minerals in the ore so that insoluble impurities can be separated. The purified alumina is then used to produce aluminium. Caustic soda is commonly used as a reagent in chemical reactions. Caustic soda is used in the saponification reaction to manufacture soap. In detergents, it is a part of the process of neutralisation of LAB. Caustic soda solution is used in the exploration, production and processing of petroleum and natural gas. It is also used as an adsorbent for carbon dioxide in light petroleum fractions; a treatment step in removal of various sulphur compounds. Caustic soda solution is used in the pulping and bleaching process and de-inking of waste paper. Caustic soda forms an important input in the steel industry. It is used to clean steel. Caustic soda solution is used to process cotton and dye synthetic fibres such as nylon and polyester. Mercerising of fibre with sodium and hydroxide solution provides greater tensional strength and consistent lustre. It removes waxes and oils from the fibre to make it more receptive to bleaching and dying. In rayon it is used during the viscose process to extract cellulose from pulp. Caustic soda solution is used in the treatment of water by regenerating the anion resin bed. It is used on a large scale in DM plants." Approvals : "ISO 9001:2015 ISO 14001:2015" Cas No : 1310-73-2
