Abstract
Solid detergent compositions for dishwashing or warewashing compositions and applications of use are disclosed. In particular, solid carbonate-based compositions that do not require a traditional dispenser for controlled rate of release over multiple cycles are disclosed. Compositions, methods of employ and cleaning using the same are disclosed.
Claims20
A homogenous solid controlled release composition for cleaning wares comprising:
- a carbonate alkalinity source;
- between about 1 wt-% and about 20 wt-% of at least one polysaccharide material comprising carboxymethylcellulose (CMC);
- and
- at least one active ingredient cleaning agent comprising a nonionic surfactant, wherein the solid composition is a homogenous multi-use composition providing controlled release of the at least one active ingredient cleaning agent and is not encapsulated with delayed release chemistry;
- and
- wherein the at least one polysaccharide material has an about 1 wt-% to about 2 wt-% aqueous solution viscosity (25 dC) between about 1 cps and about 5000 cps.

A system for cleaning wares in an automatic dishwashing environment comprising:
- a solid controlled release composition comprising a carbonate alkalinity source, between about 1 wt-% and about 20 wt-% of at least one polysaccharide material comprising carboxymethylcellulose (CMC), and at least one active ingredient cleaning agent comprising a nonionic surfactant;
- wherein the solid composition is a homogenous 2-in-1 composition providing a detergent and rinse aid in a single solid composition, wherein the solid is a multi-use composition providing controlled release of the at least one active ingredient cleaning agent;
- wherein the solid is not encapsulated with delayed release chemistry;
- wherein the system does not include a dispensing system;
- and
- wherein the at least one polysaccharide material has an about 1 wt-% to about 2 wt-% aqueous solution viscosity (25 dC) between about 1 cps and about 5000 cps, and/or has a degree of substitution (D.S.) between zero and about 3.
