Calcium peroxide is a white or yellowish solid peroxide which slowly decomposes to release oxygen at a "controlled" rate when in contact of hydrous media. Calcium peroxide is of the most temperature stable inorganic peroxides. It decomposes slowly in moist air, is practically insoluble in water, and dissolves in acids, forming hydrogen peroxide. A 1:100 aqueous slurry has a pH of about 12. Except for its stable oxygen releasing capability, calcium peroxide has similar functions of other peroxides e.g. bleaching, disinfecting, deodorizing. Calcium peroxide is environmentally friendly due to its product properties.
