Abstract
A unit dose laundry composition includes from 1 wt. % to 10 wt. % of one or more coated enzymes, from 1 wt. % to 40 wt. % of a bleach composition comprising an oxidizing agent and one or more bleach activators, from 15 wt. % to 80 wt. % of a surfactant composition, and one or more of an alkaline compound, a detergent builder, a chelant, or a polymer composition. The unit dose laundry composition is in the form of a powder, which has a bulk density of from 500 g/L to 1300 g/L, encapsulated a polymer film. A method of making the unit dose laundry composition includes combining one or more liquid active components with one or more high absorbing solid active components to produce a powder intermediate which may be blended with other solid components.
