Calcium Peroxide
What is Calcium Peroxide?
Calcium peroxide is an inorganic compound with the formula CaO2, appearing as a white to grayish powder. It is synthetically produced and valued in cosmetics for its ability to release oxygen slowly upon contact with water or skin. Primarily used in oxidative hair colorants and bleaching products, it facilitates controlled oxidation to develop dyes or lighten hair by breaking down melanin. In oral hygiene formulations like toothpastes and whiteners, it aids in stain removal through peroxide action. This gradual decomposition distinguishes it from faster-acting hydrogen peroxide, enhancing formula stability and minimizing irritation risks. Its role ensures effective performance while maintaining product integrity during storage.
