Patent ID: 7431775

Claim:
A stabilized basic aqueous liquid detergent composition comprising: a) 0.1 wt % to 15% of hydrogen peroxide; b) about 10 ppm by weight to about 1 wt % of a stannate stabilizer; c) at least about 10 ppm by weight of a phosphonic acid chelating agent or a mixture of phosphonic acid chelating agents; d) at least about 10 ppm by weight of an aromatic chelating agent or a mixture of aromatic chelating agents; e) optionally, a sequestrant or a mixture of sequestrants; f) 0.1 wt % to 60 wt % of an anionic surfactant or mixture of anionic surfactants; g) 0.1 wt % to 60 wt % of a non-ionic surfactant or mixture of anionic surfactants; e) 0.1 wt % to 60 wt % of a builder or a mixture of builders; and f) water; in which: the phosphonic acid chelating agent or agents, the aromatic chelating agent or agents, and the sequestrant or sequestrants together comprise about 20 ppm by weight to 10 wt % of the composition; the composition comprises less than about 10 ppm of pyrophosphate; the composition has a pH greater than 7.0; and the amount of active oxygen lost when the composition is heated at 85±1° C. for 24 hours is 20% or less.
