CALCIUM CHLORIDE
ANHYDROUS, DIHYDRATE AND 30% SOLUTION FORMS
MATERIAL & FUNCTION
Solid forms of calcium chloride are odorless, white to off-white pellets, mini-pellets or flakes. Commercial forms of the solid are either anhydrous (CaCl2 anhydrous, 94 โ 97% CaCl2) or Calcium Chloride dihydrate (CaCl2.2H2O; 74-78% CaCl2). A 30% solution is also available. Food Grade and Technical Grade (Feed Grade) are available. PROPERTIES Calcium chloride (CaCl2) is an ionic compound of calcium and chlorine. It is highly soluble in water and it is deliquescent (ie, absorbs moisture from the atmosphere to the extent that a solution forms). It is a salt that is solid at room temperature, and it behaves as a typical ionic halide.

Calcium Chloride generally recognized as safe (GRAS) by the U.S. Food and Drug Administration. The average intake of calcium chloride as food additives has been estimated to be 160-345 mg/day for individuals it is listed as a permitted food additive in the European Union for use as a sequestrant and firming agent with the E number E509. The anhydrous form has been approved by the FDA as a packaging aid to ensure dryness (CPG 7117.02).
Page 2 of 2 Safety: ingestion of concentrated or pure calcium chloride products may cause gastrointestinal irritation or ulceration. Skin and eye exposure to calcium chloride can cause irritation and even a burn. Vapors are unlikely due to physical properties, however dust or mists may cause irritation to the upper respiratory tract. Calcium chloride is an irritant, particularly on moist skin. Wear gloves and goggles or a full face shield to protect hands and eyes; avoid inhalation. Dry calcium chloride reacts exothermically when exposed to water. Burns can result in the mouth and esophagus if humans or other animals ingest dry calcium chloride pellets. Ecology: It promotes algae and higher plant growth. Chloride ions are also required for normal cellular operations in animals and humans, and serve as a micronutrient for plants, playing important roles in photosynthesis and osmoregulation. Calcium chloride is considered to be practically non-toxic to aquatic organisms and bioaccumulation is unlikely APPLICATIONS Calcium Chloride is used for its hygroscopic property, it can be applied to keep a liquid layer on the surface of the roadway, which holds dust down.http://en.wikipedia.org/wiki/Calcium_chloride - note-0#note- 0 It is used in concrete mixes to help speed up the initial setting, however chloride ion leads to corrosion of steel rebar, so it should not be used in reinforced concrete. Oil and gas well fluids โ to boost the efficiency of drilling and the completion of wells Miscellaneous smaller applications โ tyre ballast, water treatment, hydrocarbon desiccant, refrigeration brine, food processing agent or coagulating agent and additive for foods Industrial processing โ as additives in plastics, for calcium salt production, drainage aids for wastewater treatment, etc. CAUTION Avoid contact with skin and eyes and avoid breathing dust.
