Thioglycolic acid (1.8%) and 35% aqueous hydrogen peroxide (1.8%) were charged with mixing to the same vessel with flushing between charges. At the completion of the exotherm. Sodium hydroxide (6.4%) aqueous was added with the stirring while maintaining a temperature below 70° C. Seven percent water is added and the material mixed further to produce Composition A.
