Home and personal care
Caustic soda is used in the saponification reaction to manufacture soap . In detergent 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 .
Pulp and paper
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 . Merceising 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 .
