Abstract
Detergent compositions comprise a water-soluble builder, an enzyme and a polymeric dye transfer inhibiting agent, wherein a means is provided for delaying the release of the enzyme relative to the release of the water-soluble builder to the wash solution. The time to achieve a concentration that is 50% of the ultimate concentration of the water-soluble builder is less than 60 seconds, and the time to achieve a concentration that is 50% of the ultimate concentration of the enzyme is more than 90 seconds.
