Description:
Calcium peroxide or calcium dioxide is the inorganic compound with the formula CaO2. It is the peroxide (O22−) salt of Ca2+. Commercial samples can be yellowish, but the pure compound is white. It is almost insoluble in water.
Application:
CALCIUM PEROXIDE is used in a similar manner for environmental restoration programs. It is used to restore soil and groundwater contaminated with petroleum hydrocarbons by stimulating aerobic microbial degradation of the contaminants in a process known as Enhanced In-Situ Bioremediation. As a food additive it is used as flour bleaching agent and improving agent. Most calcium peroxide is used as a dough conditioning aid or for soil remediation (decontamination). When used in doughs, calcium peroxide is decomposed during baking. Some claim calcium peroxide is used in toothpastes as a whitener.
