**Chemical Formula:** CaCl₂·2H₂O
**Calcium Chloride Dihydrate** is a white, crystalline salt known for its strong hygroscopic properties. It readily absorbs moisture from the environment and dissolves quickly in water, releasing heat. This makes it a highly effective agent in de-icing, moisture control, and industrial drying. Its versatility also extends to use in food processing, construction, and laboratory settings.
**Appearance:**
White, odorless crystalline granules or powder
**Uses:**
**Food & Beverage Industry:**
Used as a firming agent in canned vegetables, a stabilizer in cheese production, and a source of calcium in beverages. Approved for use in food-grade applications under specific guidelines.
**Industrial Applications:**
Commonly used for dust control on unpaved roads, concrete acceleration in construction, and as a desiccant in industrial drying systems. Also functions as a brine solution in refrigeration systems.
**Pharmaceutical & Laboratory Use:**
Used as a reagent in analytical chemistry and in pharmaceutical formulations that require calcium ions for stabilization or buffering.
**Water Treatment:**
Acts as a coagulant in wastewater treatment to improve solids separation and reduce phosphorus levels.
**De-icing & Moisture Control:**
Widely applied in winter road maintenance as a de-icing compound and in commercial desiccant products for packaging and storage.
