Calcium peroxide

Calcium peroxide (CAS 1305-79-9), also known commercially as Calper or calcium dioxide, is a solid oxidizing agent that releases oxygen slowly in the presence of moisture.

Where is Calcium peroxide used?

• Food processing: dough conditioner that strengthens gluten networks, improving machinability and volume of baked goods
• Soil and groundwater remediation: in-situ oxygen source stimulating aerobic biodegradation of organic contaminants
• Water treatment: biocide and oxidant controlling microbial growth and reducing biological oxygen demand in effluent streams
• Textile and paper processing: bleaching agent for whitening fibers and pulp without chlorine-based process complexity
• Technical grades serve agricultural, remediation, and industrial end uses where food compliance is not required.

Commercial specifications

• Active oxygen content typically 60% to 75% depending on grade
