Calcium chloride is an inorganic compound, a salt with the chemical formula CaCl2. It is a white crystalline solid at room temperature, and it is highly soluble in water. It can be created by neutralising hydrochloric acid with calcium hydroxide.
Calcium chloride is commonly encountered as a hydrated solid with generic formula CaCl2·nH2O, where n = 0, 1, 2, 4, and 6.

De-icing and Road Surfacing:
By depressing the freezing point of water, calcium chloride is used to prevent ice formation and is used to de-ice.

Road surfacing :
The second largest application of calcium chloride exploits its hygroscopic nature and the tackiness of its hydrates; calcium chloride is highly hygroscopic and its hydration is an exothermic process. A concentrated solution keeps a liquid layer on the surface of dirt roads, which suppresses the formation of dust. It keeps the finer dust particles on the road, providing a cushioning layer.

Food:
The average intake of calcium chloride as food additives has been estimated to be 160–345 mg/day. Calcium chloride is permitted as a food additive in the European Union for use as a sequestrant and firming agent. It is considered as generally recognized as safe (GRAS) by the U.S. Food and Drug Administration.

• • As a firming agent, calcium chloride is used in canned vegetables.
• • Used in firming soybean curds into tofu and in producing a caviar substitute from vegetable or fruit juices.
• • Commonly used as an electrolyte in sports drinks and other beverages, including bottled water.
• • The extremely salty taste of calcium chloride is used to flavour pickles without increasing the food's sodium content.
• • In brewing beer, sometimes used to correct mineral deficiencies in brewing water.
• • In cheesemaking, added to processed (pasteurized/homogenized) milk to restore the natural calcium–protein balance in casein.
• • Used to prevent cork spot and bitter pit on apples by spraying on the tree during the late growing season.

Laboratory and Related Drying Operations:

• • Drying tubes are frequently packed with calcium chloride; kelp is dried with calcium chloride for use in producing sodium carbonate.
• • Anhydrous calcium chloride has been approved by the FDA as a packaging aid to ensure dryness.
• • The hydrated salt can be dried for re-use but will dissolve in its own water of hydration if heated quickly, forming a hard amalgamated solid when cooled.

Other applications:

• • Used in concrete mixes to accelerate initial setting; however, chloride ions can corrode steel rebar, so it should not be used in reinforced concrete.
• • The anhydrous form may also be used for this purpose and can help measure moisture in concrete.
• • Included as an additive in plastics, fire extinguishers, and blast furnaces (to control scaffolding), as well as in fabric softener as a thinner.
• • The exothermic dissolution is utilized in self-heating cans and heating pads.
• • In the oil industry, used to increase the density of solids-free brines and to inhibit swelling clays in the water phase of invert emulsion drilling fluids.
• • Acts as a flux material, decreasing melting points.
• • Used in the production of activated charcoal.
• • Can precipitate fluoride ions from water as insoluble calcium fluoride (CaF₂).
• • Used as an ingredient in ceramic slipware.
• • Calcium chloride dihydrate (20% by weight) dissolved in ethanol (95% ABV) has been used as a sterilant for male animals.

Metal reduction flux: CaCl2 is used as a flux and electrolyte in the FFC Cambridge electrolysis process for titanium production.

When properly stored to protect from moisture contact, the expected shelf life for all calcium chloride packaged products is 36 months.
