First Claim
Patent Images
1. An 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 composition, the binding agent comprising;
(i) an alkali metal carbonate monohydrate;
(ii) an organic sequestrant comprising an organo phosphonate or an organo amino acetate; and
(iii) water;
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, and the binding agent has a melting transition temperature of greater than about 120°

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.
