  • Toxicity Summary: IDENTIFICATION AND USE: Calcium peroxide is white or yellowish powder. It is used as a stabilizer for rubber. Other uses including seed disinfectant, dentifrices, dough conditioners, antiseptic, bleaching of oils, modification of starches, high temperature oxidation. An important application of calcium peroxide is for curing the polysulfide sealants used in double glazing window units. Calcium peroxide is also used at several gold mines in Australia to increase recovery of gold and reduce the consumption of cyanide. Calcium peroxide has been identified as being used in hydraulic fracturing as a breaker. HUMAN EXPOSURE AND TOXICITY: Contact with calcium peroxide can severely irritate and may burn the skin and eyes. Exposure can irritate the eyes, nose, and throat. Prolonged exposure can damage the skin. Higher levels of calcium peroxide can irritate the lungs causing coughing and/or shortness of breath. Still higher exposures may cause a buildup of fluid in the lungs (pulmonary edema). This can cause death. ANIMAL STUDIES: Experiments with calcium peroxide revealed that the compound is not toxic to dogs treated orally. ECOTOXICITY STUDIES: New method was proposed for increasing the Source: Hazardous Substances Data Bank (HSDB)
  • Sources/Uses: Used as a rubber stabilizer, antiseptic, seed disinfectant, starch modifier, sewage deodorizer, and wastewater dechlorinator; Also used for dentifrices; in dough conditioners; for bleaching of oils; in high temperature oxidations; for curing the polysulfide sealants used in double glazing window units; to increase recovery of gold and reduce the consumption of cyanide (at gold mines); to improve the bioremediation of soils contaminated with creosote or kerosene; for removing metal ions from acidic waste streams such as coal ash leachate and acid mine drainage; in the cultivation of tomatoes, cucumbers, tobacco, and prawns (Japan); [HSDB] Used as a flour treatment agent; [JECFA] Source: Haz-Map, Information on Hazardous Chemicals and Occupational Diseases

A relatively new application for CaO2 is as a peroxide source in toothpaste and dental chewing gum products. Calcium peroxide is also used in limited quantities as a hardening accelerator for sulfide rubber, as dough conditioner in the baking industry, and as a nontoxic disinfectant for seed and grain.

  • Uses: An important application of calcium peroxide is for curing the polysulfide sealants used in double glazing window units. Calcium peroxide is also used at several gold mines in Australia to increase recovery of gold and reduce the consumption of cyanide. Calcium peroxide (PermeOx) is also used to improve the bioremediation of soils contaminated with creosote or kerosene, to deodorize sewage sludges and wastewater, and to dechlorinate wastewater and effluents. A special formulation of calcium peroxide ... is used for removing metal ions from acidic waste streams such as coal ash leachate and acid mine drainage. Source: Hazardous Substances Data Bank (HSDB)
