MOLDED DETERGENT COMPOSITION
First Claim
1. A method for manufacturing a molded detergent composition, the method comprising:
- (a) mixing a hydrated component and a hydratable component without heating to provide a mixture;
(i) 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;
(ii) the hydratable component being a component which successfully competes with the hydrated component for at least a portion of the water of hydration;
(b) molding the mixture to provide a molded detergent composition; and
(c) solidifying the molded detergent composition as a result of movement of the water of hydration from the hydrated component to the hydratable component to provide the molded detergent composition as a solid under conditions of room temperature and atmospheric pressure, wherein the step of solidifying takes between about 1 minute and about 15 minutes.

Abstract
A method for manufacturing a molded detergent composition is provided. The method includes mixing a hydrated component and a hydratable component without heating to provide a mixture, molding the mixture to provide a molded detergent composition, and solidifying the molded detergent composition as a result of movement of the water of hydration from the hydrated component to the hydratable component to provide the molded detergent composition as a solid under conditions of room temperature and atmospheric pressure. 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. Solidification of the mixture takes between about 1 minute and about 15 minutes.
