Product Application of Hydrogen peroxide CAS#7722-84-1
Hydrogen peroxide is a low-residue, high-efficiency oxidizer that delivers stable sterilization and bleaching effects in industrial formulations, with its working effectiveness depending on the concentration and pH of the formulation.
In industrial applications, hydrogen peroxide can be used as an alternative to glycerol in oxidation, bleaching, and various industrial purification formulations. It is mainly produced through standardized synthetic industrial processes.
