Calcium peroxide

Calcium peroxide is an inorganic chemical compound with the molecular formula CaO2 and CAS number 1305-79-9. This white or yellowish powder has a molecular weight of 72.08 g/mol and belongs to the family of alkaline earth metal peroxides. It serves as a stable source of oxygen and exhibits oxidizing properties, making it valuable in various industrial applications where controlled oxygen release is required.

Calcium peroxide appears as a white to pale yellow crystalline powder that is odorless under normal conditions. It is slightly soluble in water, decomposing slowly to release oxygen and form calcium hydroxide. The compound is stable under dry conditions but decomposes when exposed to moisture or heat. It has a density of approximately 2.9 g/cm³ and exhibits strong oxidizing characteristics due to its peroxide structure.

Calcium peroxide serves multiple industrial purposes as an oxidizing agent and oxygen source. It is commonly used in environmental remediation for soil and groundwater treatment, particularly in bioremediation processes. Other applications include its use as a bleaching agent in the textile industry, as an antiseptic in aquaculture, and in dental care products. It also finds application in construction materials and as a dough conditioner in food processing.

Calcium peroxide requires careful handling using appropriate personal protective equipment including safety goggles, dust masks, and chemical-resistant gloves. Work in well-ventilated areas to avoid dust inhalation and prevent accumulation of released oxygen. Avoid contact with combustible materials, acids, and reducing agents. Use non-sparking tools and equipment. Ensure proper grounding of equipment to prevent static electricity buildup during handling and transfer operations.

Calcium peroxide should be stored in a cool, dry, well-ventilated area away from direct sunlight and heat sources. Keep containers tightly sealed to prevent moisture absorption and contamination. Store separately from combustible materials, acids, reducing agents, and organic compounds due to its oxidizing nature. Use original packaging or compatible containers made of materials that resist oxidation. Maintain storage temperature below 25°C for optimal stability.

Calcium peroxide contact requires immediate action depending on exposure type. For skin contact, remove contaminated clothing and wash affected area thoroughly with soap and water for at least 15 minutes. In case of eye contact, flush immediately with clean water for 15-20 minutes and seek medical attention. If inhaled, move to fresh air immediately. For ingestion, rinse mouth with water and seek immediate medical attention without inducing vomiting.

Calcium peroxide disposal must comply with local and national waste regulations as it is classified as an oxidizing substance. Small quantities can be carefully dissolved in large amounts of water under controlled conditions, allowing decomposition to calcium hydroxide and oxygen. Large quantities require disposal through licensed hazardous waste contractors. Never dispose of in regular waste streams or pour down drains due to its oxidizing properties and potential environmental impact.

Calcium peroxide is classified under ADR Class 5.1 (Oxidizing substances) Packing Group II, requiring specific transport regulations compliance. It must be packaged in approved containers with proper labeling and documentation. Transport vehicles need appropriate placarding and emergency equipment. Drivers require ADR certification for dangerous goods transport. Segregation from incompatible materials like flammables and reducing agents is mandatory during transportation across European routes.

Calcium peroxide falls under various European chemical regulations including REACH registration requirements for manufacturers and importers. It is not classified as a SVHC (Substance of Very High Concern) substance. However, as an oxidizing agent under ADR Class 5.1, it requires compliance with transport regulations. Users must follow CLP regulation requirements for proper classification, labeling, and safety data sheet provisions when placing on the European market.
