DETERGENT COMPOSITION COMPRISING SOURCE OF HYDROGEN PEROXIDE AND PROTEASE ENZYME

摘要

There is provided 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 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 HPP = (% weight of precursor x % weight of proteolytic enzyme)/(%AvO2)<2>, 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 %AvO2 is the total amount of available oxygen present in the composition.
