STABILIZING SYSTEM FOR LIQUID HYDROGEN PEROXIDE COMPOSITIONS

摘要

Aqueous peroxide bleaching compositions including organic components such as surfactants, fluorescent whiteners and dyes are effectively stabilized by the addition of a stabilizing system comprising stabilizing effective amounts of a heavy metal chelating or sequestering agent and an aromatic amine free radical scavenging agent. Both agents must be present to achieve maximum stability. The aromatic amine free radical scavenging agent is preferably a primary or secondary aryl amine having at least one hydrogen on the nitrogen of the amine. The stabilizing system stabilizes the organic component as well as the peroxide oxidizing agent.
