Abstract
A method for manufacturing a molded detergent composition is provided. The method includes a step of mixing a hydrated component and a hydratable component to provide a mixture, and molding the mixture to provide a molded detergent composition having a melting point greater than about 30° C. The hydrated component has a melting point below about 100° C. and includes a transhydration product of anhydrous material and water of hydration. The anhydrous material has a melting point greater than about 300° C. 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 of the water of a molded detergent composition is provided.
