PURPOSE: To use hydrogen peroxide stabilized under slightly alkaline conditions as a principal component. n CONSTITUTION: A stabilized alkaline aq. hydrogen peroxide soln. contains 1.0-6.0wt.% hydrogen peroxide and 0.1-2.0wt.% mixture of one or more kinds of aminocarboxylates with acetophosphonate as a stabilizing agent. The aminocarboxylates are selected from among diethylenetriamine-pentaacetate, triethylenetetraminehexaacetate, ethylenediaminetetra-acetate, pyridine-2,6- dicarboxylate and diaminopropanoltetraacetate. The acetophosphonate is the acylated product of phosphorous acid. n COPYRIGHT: (C)1992,JPO&Japio |
