Abstract
The present disclosure relates to a solid, enzymatic detergent compositions and methods of making and using the same. In a preferred embodiment, the detergent compositions are particularly useful for cleaning medical and dental instruments. In a preferred embodiment the compositions are particularly use for cleaning ware.
Claims19
A solid detergent composition comprising:
- a solidification matrix comprising an alkali metal carbonate and an acid, wherein the acid has aqueous solubility between 0.1 and 1500 g/L at 20° C.;
- an enzyme;
- and
- a surfactant, wherein the surfactant is a nonionic surfactant, amphoteric surfactant, or a mixture thereof;
- wherein upon dilution the composition provides a pH of between about 6 and about 10;
- wherein the solid is a cast solid, extruded solid, molded solid, a powder, or pressed solid.

A solid detergent composition comprising:
- a solidification matrix comprising an alkali metal carbonate and a polycarboxylic acid or salt thereof, wherein the acid has aqueous solubility between 0.1 and 1500 g/L at 20° C., wherein the alkali metal carbonate is between about 15 wt. % and about 75 wt. % of the composition, and wherein the polycarboxylic acid is between about 15 wt. % and about 50 wt. % of the composition, and wherein the polycarboxylic acid or salt thereof has between 2 and 4 carboxyl groups;
- between about 0.1 wt. % and about 25 wt. % of an enzyme;
- and
- between about 0.5 wt. % and about 25 wt. % of a surfactant, wherein the surfactant is a nonionic surfactant, amphoteric surfactant, or a mixture thereof;
- wherein upon dilution the composition provides a pH of between about 6 and about 10;
- and
- wherein the composition is a cast solid, extruded solid, molded solid, a powder, or pressed solid.
