zinc chloride[′ziŋk ′klȯr‚īd] (inorganic chemistry) ZnCl2 Water- and alcohol-soluble, white, fire-hazardous crystals that melt at 290°C, and are irritating to the skin; used as a catalyst and in electroplating, wood preservation, textile processing, petroleum refining, medicine, and feed additives. Zinc Chloride ZnCl2, a white hygroscopic crystalline compound, with a density of 2.9 g/cm3, a melting point of 322°C, and a boiling point of 722°C. Its solubility in water is 79.8 percent (at 20°C). Concentrated solutions of zinc chloride are acidic. Zinc chloride is produced by dissolving zinc or zinc oxide in hydrochloric acid and then subjecting the solution to evaporation, by heating molten zinc in a stream of chlorine, or by other methods. It is used in calico printing and for the production of dental cements. It is also used as a wood preservative and to remove oxides from metal surfaces prior to welding.

zinc [zingk] a chemical element, atomic number 30, atomic weight 65.37, symbol Zn. (See Appendix 6.) It is a trace element in the diet, a component of several enzymes, including DNA and RNA polymerases and carbonic anhydrase. It is abundant in red meat, shellfish, liver, peas, lentils, beans, and rice. A well-balanced diet assures adequate intake of zinc. Those who may suffer from zinc deficiency include persons on a strictly vegetarian diet and those who are on a high-fiber diet. In the latter case, the zinc is bound to the fiber and is eliminated in the feces without having been absorbed through the intestinal wall. Poor absorption of zinc also can occur in persons with chronic and severe bowel disease. The recommended daily intake is 12–15 mg for an adult. A severe deficiency of zinc can retard growth in children, cause a low sperm count in adult males, and retard wound healing. Signs of a deficiency include anorexia and a diminished sense of taste. An excessive intake of zinc (usually in those who work with the metal or breathe its fumes) can either cause pneumoconiosis or interfere with the body's use of copper and other trace elements, producing diarrhea, nausea, vomiting, and other signs of intestinal irritation.zinc acetate a salt used as an astringent and styptic.zinc chloride a salt used as a nutritional supplement in total parenteral nutrition and applied topically as an astringent and a desensitizer for dentin.zinc oxide a topical astringent and skin protectant; also a sunscreen.zinc stearate a powder of zinc in a compound with stearic and palmitic acids; used as a water-repellent skin protectant in dermatoses.zinc sulfate a topical astringent for mucous membranes, especially those of the eye.zinc undecylenate the zinc salt of undecylenic acid; it is a topical antifungal.zinc chlo·rideZnCl2; formerly used as a caustic for the removal of cutaneous cancers, nevi, etc., and in weak solution in the treatment of gonorrhea and conjunctivitis.
