    • A non-phosphate builder-containing detergent composition comprising a surfactant, and a) at least 0.5% by weight of a source of hydrogen peroxide; b) from 0.01% to 10% by weight of an organic peroxyacid bleach precursor; c) from 0.001% to 5% by weight of a proteolytic enzyme; d) an alkalinity source having the capacity to deliver alkalinity to a wash solution as measured by the alkalinity release test described herein, such that the % weight of NaOH equivalent of the composition is greater than 10.6% by weight of the composition, and wherein the detergent composition has a Hydrogen peroxide Precursor Proteolytic enzyme (HPP) Index of at least 0.35 as defined by the formula: ##EQU1## wherein the % weight of proteolytic enzyme in the formulation is based on an enzyme activity of 13 knpu/g of the enzyme particle, and wherein the % AvO.sub.2 is the total amount of available oxygen present in the composition is provided. The detergent composition optionally comprises a water-soluble organic polymeric polycarboxylic compound, which when present, is present in the detergent composition in an amount wherein the weight ratio of water-soluble organic polymeric polycarboxylic compound to the alkalinity source is 0.0732:1 or less.
