ABSTRACT:
An aqueous composition containing hydrogen peroxide, or a precursor which will form said peroxide in aqueous solution, is inhibited from decomposition in the presence of small amounts of copper, iron, manganese or other transition metal ions and in the presence of significant amounts of alkaline earth metal ions, e.g. Ca or Mg, by the presence of a combination of inhibitors one being from the group consisting of alkyleneaminephosphonic acids and the other being from the group consisting of polyalkylenepolycarboxylic acids and their analogous amides and sulfonic acid derivatives.
