Abstract
The dimensionally stable alkaline solid block warewashing detergent uses an E-form binder forming a solid comprising a sodium carbonate source of alkalinity, a sequestrant, a surfactant package and other optional material. The solid block is dimensionally stable and highly effective in removing soil from the surfaces of dishware in the institutional and industrial environment. The E-form hydrate comprises an organic phosphonate and a hydrated carbonate.

A detergent composition comprising:
- (a) about 20 to 80 wt % of alkali metal carbonate;
- (b) 1 to 30 wt % of an organic sequestrant;
- (c) about 0.01 to 1.3 mole of water per mole of carbonate;
- and
- wherein the composition comprises non-hydrated alkali metal carbonate and a binding agent comprising mono-hydrated alkali metal carbonate and organic sequestrant, and the mole ratio of alkali metal carbonate to organic sequestrant in the binding agent is in range of about 3:1 to about 7:1, and the composition is substantially free of a second source of alkalinity.
