Abstract
Stabilizer formulations have been developed for commercial hydrogen peroxide stored in stainless steel containers. These stabilizers, which include benzene phosphonous acid, 2,2'-dithiobenzoic acid, 1-allyl-thiourea, and thiocarbanilide are effective in the presence of typical decomposition catalysts when used in conjunction with typical organic phosphonic stabilizer systems, even when the commercial organic phosphonic stabilizers are present in less than the usually recommended quantities.
