  • It is the main raw materials for the production of soap.
  • In oil refining industry it is used to remove the acids in the oil and improve the smell and color of the oil & petroleum products.
  • In textile industry, caustic soda is used to make rayon and mercerization of cotton.
  • In paper making industry, it is used as a reagent to treat wood, rice stalks and other fibers.
  • Industrial water treatment: Regeneration of ion exchangers, waste water treatment.
  • Food industry: Purification of fats and oils and removal of fatty impurities.
  • Caustic soda is used for the extraction and purification of aluminum.
  • It is supplied in 250 kg mild steel drums.
  • Store in a dry place away from acids, metals like aluminum magnesium and zinc that cause formation of flammable hydrogen.
Immediately remove all contaminated clothing and equipment effected by the Caustic.
Flush the exposed area thoroughly with a lot of water, followed by washing with a solution of 5 %
ammonium chloride in water.
If caustic contacts the eyes, they should be irrigated immediately with plenty of water for at least 15
minutes.
Hold the eyelids opened during irrigation. The eyes should then be washed with a dilute boric acid
solution and wash the eye with water for an additional 15 minutes.
A physician should be seen immediately after the eye is thoroughly washed.
For personal protection, use face shields, gloves, gum-boots and protective suites.
Caustic soda (solid) is packed in mild steel drums & each packing weighs 250 kg net.
