calcium chloride powder

About calcium chloride powder

Calcium chloride powder (CaCl) is a white, crystalline, inorganic compound that is highly soluble in water. It is widely used in various industries because of its ability to attract and hold moisture (hygroscopic nature).

Key Properties

• Chemical formula: CaCl

• Appearance: White, crystalline or powder form

• Taste: Salty (similar to table salt but more bitter)

• Solubility: Highly soluble in water and alcohol

• Hygroscopic: Absorbs moisture from the air, can even turn liquid (deliquescent)

Uses of Calcium Chloride Powder

1. De-icing & Dust Control

   • Commonly spread on roads in winter to melt ice/snow.

   • Used on unpaved roads to reduce dust.

2. Food Industry

   • As a firming agent in canned vegetables, tofu, and pickles.

   • Added to cheese production (improves curd formation).

   • In brewing, it adjusts water hardness for better flavor.

3. Construction

   • As a concrete accelerator (speeds up setting time).

4. Desiccant

   • Used in drying tubes, packaging, and air dehumidifiers.

5. Water Treatment

   • Helps increase water hardness in pools.

6. Medical

   • In small doses, used in intravenous (IV) therapy for hypocalcemia.

Safety & Handling

• Non-toxic in small amounts (food-grade), but industrial-grade should not be ingested.

• Contact may cause mild skin or eye irritation due to its drying effect.

• Store in airtight containers to prevent it from absorbing moisture and clumping.
