What Is Used For

Sodium chloride is widely used across various industries and in everyday life for its chemical properties and safety profile[1].

  • Food Industry: Used as a preservative, flavor enhancer, and texture modifier; essential in curing meats and making brines[1][2][5].
  • Medical Uses: Found in intravenous saline solutions, wound cleaning, nasal irrigation, eye drops, and as a component for maintaining fluid and electrolyte balance[5][7].
  • De-Icing Roads: Applied to roads and walkways in winter to melt ice and prevent its formation, accounting for a significant portion of global salt use[1][3][8].
  • Chemical Industry: A key raw material in manufacturing chemicals such as chlorine, sodium hydroxide, hydrochloric acid, and sodium carbonate (via the chlor-alkali or Solvay process)[1][2][6].
  • Water Treatment: Used in water softening and the regeneration of ion exchange resins, removing hardness-causing ions from water[2][3].
  • Metal Processing: Utilized as a flux, in metal refining, extraction of metals from ores, and for removing impurities[2][4].
  • Oil and Gas Industry: Used in drilling fluids to control formation pressure and stabilize well walls[1][2][3].
  • Dyeing and Textile Industry: Helps fix dyes to fabrics and standardize colors; used as a brine rinse and to enhance dye yield[1][2][4].
  • Rubber and Paper Industries: Helps separate rubber from latex and is used in the production of chemicals for paper bleaching[1][4].
  • Animal Nutrition: Added to animal feed as an essential mineral source and to enhance palatability[2].
  • Miscellaneous Uses: Used in household cleaning, soil stabilization in construction, tanning leather, welding, soldering, pottery glazing, laboratory analysis, and more[1][3].
