Abstract
A solid functional material comprises a functional agent such as a cleaning composition, a sanitizing agent, where a rinse agent, etc. in a solid block format. The solid block is formed by a binding agent that forms the active ingredients into a solid block. The binding agent comprises a phosphonate or amino acetate sequestrant, a carbonate salt and water in an E-Form hydrate. These materials at a specific mole ratio form a novel binding agent that can form functional materials into a solid matrix form.

A solid alkaline detergent composition comprising:
- (a) an effective amount of a source of alkalinity sufficient to provide soil removal;
- and
- (b) a binding agent dispersed throughout the solid detergent, the binding agent comprising an alkali metal carbonate monohydrate, an organic sequestrant comprising an organo phosphonate or an organo amino acetate and water, wherein the organic sequestrant cooperates in the formation of the binding agent, and wherein, in the binding agent, for each mole of the organic sequestrant there is about 3 to 10 moles of the carbonate monohydrate and 5 to 15 moles of water;
- wherein the binding agent has a melting transition temperature of greater than about 120° C.
