• Chemical Classes: Other Classes -> Inorganic Oxidizing Agents
• Canonical SMILES: [O-]Cl.[O-]Cl.[Ca+2]
• Recent ClinicalTrials: Efficacy of a Novel CCH Protocol for PD Among Prior Non-responders
• Inhalation Risk: A harmful concentration of airborne particles can be reached quickly when dispersed, especially if powdered.
• Effects of Short Term Exposure: The substance is corrosive to the eyes, skin and respiratory tract. Corrosive on ingestion. Inhalation of decomposition products may cause lung oedema. The effects may be delayed. Medical observation is indicated.
• Chemical Composition: Calcium hypochlorite (Ca(ClO)2) is an inorganic calcium salt containing hypochlorite. It is a strong oxidant and its aqueous solution is alkaline.
• Role as a Bleaching Agent: Calcium hypochlorite has a role as a bleaching agent and is commonly used for industrial sterilization, water treatment, and bleaching processes.
• Postharvest Disinfection: Calcium hypochlorite is utilized for postharvest disinfection of fruits and vegetables due to its strong sterilization ability and minimal impact on human health. It is effective in sterilizing produce surfaces while preserving their quality.
• Properties and Uses: Properties and Uses of calcium hypochlorite are similar to those of sodium hypochlorite. It is shipped in dry form and needs to be dissolved in water for use in postharvest produce treatment, making shipping more cost-effective compared to sodium hypochlorite, which is only stable in solution.
• Water Purification: Calcium hypochlorite is dissolved in distilled water for industrial sterilization and water treatment purposes. It is relatively stable and has a higher available chlorine content compared to sodium hypochlorite.
• Antimicrobial Action: Studies have shown that calcium hypochlorite solutions have antimicrobial action against bacteria such as Enterococcus faecalis, making it effective for disinfection purposes.
• Industrial Applications: Calcium hypochlorite is utilized in various industrial processes, including flotation separation of sulfide minerals, disinfection of swimming pools and food containers, and bleaching of cellulose due to its strong oxidizing properties.
