Stabilized liquid hydrogen peroxide bleach compositions

Abstract From the Canadian patent

Aqueous peroxide bleaching compositions that include surfactant, fluorescent whiteners and dyes are effectively stabilized by the addition of a heavy metal chelating agent and a free radical scavenging agent. Both agents must be present to achieve maximum stability. Particularly preferred chelating agents are the amino polyphosphonates. Particularly preferred free radical scavenging agents are the hydroxybenzenes and especially substituted phenols. Not only is the peroxide oxidizing agent stabilized but, surfactant, fluorescent whitener, and dye as well.
