Documented Uses

• Sodium chloride (NaCl). A colorless, cubic crystal or white, crystalline powder, found widely distributed over the earth, in sea water, etc., which is a necessary constituent of the body and consequently of the diet. It makes up over 90 percent of the inorganic constituents of the blood serum and is the principal salt involved in maintaining osmotic tension of the blood and tissues. (From Dorland, 27th ed) [ChemIDplus] Used in the hide preservation and pickling stages of leather production; [PMID 21938525]
• Leather Tanning and Processing [Category: Industry]
• Over 14,000 different uses for salt have been identified ...the salt industry generally classifies salt uses by 5 principal categories: 1) chemical; 2) highway deicing and stabilization; 3) food use and processing; 4) agriculture; 5) water conditioning. Remaining uses are categorized as miscellaneous.
• The major industries that use salt include in descending order of quantity consumed oil and gas exploration, textiles, dyeing, pulp and paper, metal processing, tanning and leather treatment, and rubber manufacture
• Chemical (sodium hydroxide, soda ash, hydrogen chloride, chlorine, metallic sodium), ceramic glazes, metallurgy, curing of hides, food preservative, mineral waters, soap manufacture (salting out), home water softeners, highway deicing, regeneration of ion-exchange resins, photography, food seasoning, herbicide, fire extinguishing, nuclear reactors, mouthwash, medicine (heat exhaustion), salting out dyestuffs, supercooled solutions. Single crystals are used for spectroscopy, UV, and infrared transmissions.
