Calcium Chloride

Product Overview

Calcium Chloride (CaCl₂) is an inorganic compound offered in Technical Grade as a white crystalline solid or colorless liquid with high water solubility and pronounced hygroscopicity. This material is stabilized to deliver consistent performance across multiple industrial contexts, including moisture control, de-icing, and chemical processing. Its hygroscopic nature makes it particularly effective as a desiccant and desiccating agent in drying systems, while its strong affinity for water enables efficient crystallization control and brine formation for de-icing and dust suppression. The product complies with technical-grade specifications suitable for demanding applications, with tight impurity controls verified by standard analytical methods such as IC, ICP-OES, and gravimetric techniques.

In addition to moisture management, Calcium Chloride serves as a versatile reagent in laboratories and a functional additive in food processing where controlled ionic strength and firming action are required. The material is stored under dry conditions to prevent clumping and maintain flowability, and is shipped under appropriate hazard classifications to ensure safe handling. The supplier adheres to industry standards for Technical Grade materials and provides a comprehensive SDS, COA, and technical notes to support qualification and regulatory considerations.

Common Applications

• De-icing Agent: Transportation sector uses CaCl₂ brines for rapid ice and snow melt on roads and walkways, delivering low-temperature performance and effective hygroscopic hydration.
• Moisture Control: Construction and environmental control applications leverage Calcium Chloride to regulate humidity and prevent condensation in enclosed spaces and concrete pours.
• Desiccant: Industrial drying processes employ CaCl₂ to absorb moisture, maintain product quality, and control moisture migration in packaging lines.
• Chemical Reagent: Laboratory workflows utilize CaCl₂ as a reactive salt for precipitation, complexation studies, and calibration of analytical methods.
• Food Additive: In food processing, calcium chloride acts as a firming agent and preservative adjunct, supporting texture stabilization and controlled Mineral content in certain products.

Safety Precautions

Handle Calcium Chloride with appropriate PPE including chemical-resistant gloves, splash goggles, and protective clothing. Store in a cool, dry place away from moisture, in tightly closed containers, and ensure adequate ventilation to minimize inhalation of dust. Keep away from incompatible materials such as strong acids to prevent exothermic reactions and potential hazard escalation.

In case of exposure, flush eyes with plenty of water for several minutes; wash skin with soap and water if contact occurs. If inhaled, move to fresh air and seek medical attention if irritation persists; for ingestion, rinse mouth and avoid inducing vomiting, seeking medical advice as needed. In the event of a spill, contain and collect the material using appropriate absorbents and dispose of according to local/regional regulations. Transport as UN 1744, Calcium Chloride, Class 8, PG II.
