METHOD FOR WASHING AN ARTICLE USING A MOLDED DETERGENT COMPOSITION
First Claim
1. A method for washing an article comprising:
- (a) generating an aqueous use solution from a solid block molded detergent composition, the molded detergent composition comprising a result of mixing and molding a mixture without heating, the molded detergent composition comprising;
(i) a hydrated component, a hydratable component and an enzyme;
(ii) the hydrated component being provided in a solid state during mixing and molding;
(iii) the hydratable component comprising water, if present at all, at a level of less than about 2 wt. % based on the weight of the hydratable component;
(iv) the hydratable component being a component which successfully competes with the hydrated component for at least a portion of the water of hydration; and
(v) the mixture comprising the enzyme in an amount of between about 0.01 wt. % and about 10 wt. % based on the weight of the mixture; and
(b) washing the article with the use solution.

Abstract
A method for washing an article using a molded detergent composition is provided. The method includes generating an aqueous solution from a solid block molded detergent composition and washing the article with the use solution. The molded detergent composition is a result of mixing and molding a mixture without heating. The molded detergent composition includes a hydrated component, a hydratable component and an enzyme. The hydrated component is provided in a solid state during mixing and molding. The hydratable component includes water, if present at all, at a level of less than about 2 wt. % based on the weight of the hydratable component. The hydratable component is a component which successfully competes with the hydrated component for at least a portion of the water of hydration. The enzyme constitutes between about 0.01 wt. % and about 10 wt. % of the mixture.

12. A method for cleaning an article comprising:
-
(a) diluting a molded detergent composition to form a use solution, the molded detergent composition formed as a result of mixing and molding a mixture without heating, the molded detergent composition consisting essentially of; (i) a hydrated component, a hydratable component and an enzyme; (ii) wherein a weight ratio of the hydrated component to the hydratable component is between about 5;
1 and about 20;
1 based on an anhydrous weight of each component;(iii) the hydratable component comprising less than about 2 wt. % water based on the weight of the hydratable component; (iv) the hydratable component being a component which successfully competes with the hydrated component for at least a portion of the water of hydration; and (b) contacting the article with the use solution. - View Dependent Claims (13, 14, 15, 16, 17)
