Claims10
A laundry article used for cleaning fabrics comprising:
- a. a water-insoluble nonwoven substrate;
- b. a detergent composition solidified on the substrate in a first zone;
- and,
- c. an enzyme-containing composition solidified on the substrate in a second zone that is geographically different than the first zone,
- wherein the enzyme-containing composition comprises an enzyme embedded in a matrix and wherein the matrix is composed of fatty acids, fatty acid soaps, polyols or mixtures thereof, wherein the matrix is at a level from 85% by weight to 99.9% by weight of the enzyme-containing composition.

A method of producing a laundry article used for cleaning fabrics comprising a water-insoluble nonwoven substrate, a detergent composition and an enzyme-containing composition, the method comprising:
- a. melting a detergent composition;
- b. melting a matrix material selected from the group consisting of fatty acids, fatty acid soaps, polyols and mixtures thereof;
- c. adding a liquid formulation comprising an enzyme to the molten matrix material to form an enzyme-containing composition, wherein the matrix material is at a level from 85% by weight to 99.9% by weight of the enzyme-containing composition;
- d. supplying a length of nonwoven substrate;
- and
- e. coating said substrate with the molten detergent composition in a first zone and the molten enzyme-containing composition in a second zone that is geographically different than the first zone and allowing the resulting detergent and enzyme-containing compositions to cool and solidify on the substrate.
