ABSTRACT:
The present invention relates to aqueous alkaline bleach compositions containing hydrogen peroxide. Under alkaline conditions, it is particularly difficult to prevent the hydrogen peroxide decomposing excessively rapidly during storage, but the addition of an alkaline additive minimizes any change in the pH of washing solutions obtained by dissolution of generally bleach free washing compositions containing anionic surfactants. Hydrogen peroxide-containing aqueous alkaline bleach having acceptable peroxide stability can be obtained by employing ethanol or isopropanol in conjunction with a phosphonate, especially ethylene (diamino tetramethylene phosphonate,) particularly with a polyhydroxy carboxylate, preferably gluconate, or an amino acetate. The liquid bleach can contain a small proportion of a surfactant.
