Abstract
A cleaning composition includes a carboxymethyl carbohydrate polymer, sodium carbonate, and water. The carboxymethyl carbohydrate polymer, sodium carbonate, and water interact to form a hydrate solid. The solid cleaning composition exhibits little or no swelling even when heated to temperatures up to 120° C.
Claims20
A solid composition comprising:
- (a) At least one carboxymethyl carbohydrate polymer;
- (b) sodium carbonate;
- and
- (c) water, wherein the solid composition is a hydrate solid.
1 more element
A solid cleaning composition comprising:
- (a) between about 0.5% and about 30% of at least one carboxymethyl carbohydrate polymer by weight of the solid cleaning composition;
- (b) between about 2% and about 50% water by weight of the solid cleaning composition;
- (c) less than about 40% builder by weight of the solid cleaning composition;
- (d) between about 20% and about 85% sodium carbonate by weight of the solid cleaning composition;
- and
- (e) between about 0.5% and about 10% surfactant by weight of the solid cleaning composition.
3 more elements
A method of preparing a solid cleaning composition, the method comprising:
