Soluble in water.


Urea hydrogen peroxide is an antiseptic, disinfectant and bleaching agent used in pharmaceuticals and cosmetics respectively. It is used in the whitening of teeth and relieves minor inflammation of gums, oral mucosal surfaces and lips. It finds application in the preparation of plastics, blue print development and starch modification. In addition to this, it is used as a source of hydrogen peroxide easily handled in the laboratory.


Incompatible with acetic anhydride, aniline and carboxylic acids.
