About

Calcium peroxide, also called calcium dioxide, is the inorganic compound with the formula CaO2, the peroxide salt of calcium; the pure compound is white, commercial samples can be yellowish, and it is almost insoluble in water.[1] As a solid it is relatively stable, but in contact with water it hydrolyses and releases oxygen, and treated with an acid it forms hydrogen peroxide.[1] Crest Baking Soda & Peroxide Whitening with Tartar Protection lists it among its inactive ingredients, under UNII 7FRO2ENO91 in the label's structured data.[2]
