About Zinc Chloride: Properties & Uses
A white crystalline solid, Zinc Chloride is used chiefly as a wood preservative, as a disinfectant and antiseptic. It finds wide application in Textile processing, Metallurgical Fluxes and chemical synthesis.  

It is very hygroscopic. As such it must be kept in air-tight container, in a cool dry place while ensuring that there is good ventilation around. When handling the chemical, its important that one wears rubber gloves and safety goggles.

It corrosive to metals and therefore irritating to the skin, eyes and mucous membranes. Avoid ingestion and inhalation. In case of accidental ingestion, large quantities of milk or water should be taken instantly while also seeking out medical advice. In case of contact with skins apply baking soda to neutralize the acidic effects. When contact with eyes, splash with plenty of water and seek medical attention.

It is the name of chemical compound with the formula ZnCl2.xNH4Cl and its hydrates. Hygroscopic and even deliquescent in nature, it is also regarded as a water-soluble poisonous solid used mainly as a wood preservative, a disinfectant, pharmaceutical catalyst and anti-septic.

whose nine crystalline forms are known, is colorless or white, and highly soluble in water. Reacting with Bases, it makes Zinc Hydroxide and forms acidic solutions in water and in polar organic solvents such as ethanol, acetone and ether.

Zinc Chloride Neutral solutions can be prepared with anhydrous and acetone. Samples should therefore be protected from sources of moisture, including the water vapor present in ambient air. It finds wide application in textile processing, metallurgical fluxes, and chemical synthesis.

Potential Acute Health Effects:

Very hazardous in case of skin contact (irritant), of eye contact (irritant), of ingestion, of inhalation. Hazardous in case of skin contact (corrosive, permeator), of eye contact (corrosive). The amount of tissue damage depends on length of contact. Eye contact can result in corneal damage or blindness. Skin contact can produce inflammation and blistering. Inhalation of dust will produce irritation to gastro-intestinal or respiratory tract, characterized by burning, sneezing and coughing. Severe over-exposure can produce lung damage, choking, unconsciousness or death. Inflammation of the eye is characterized by redness, watering, and itching. Skin inflammation is characterized by itching, scaling, reddening, or, occasionally, blistering.
