Abstract
A solidification matrix includes a maleic-containing terpolymer, sodium carbonate, and water. The maleic-containing terpolymer, sodium carbonate, and water interact to form a hydrate solid. The solidification matrix may be used, for example, in a solid detergent composition.
Claims17
A hydrated solid detergent composition comprising:
- (a) a maleic-containing terpolymer consisting of maleic acid/ethyl acrylate/vinyl acetate;
- (b) between about 20% and about 90% sodium carbonate by weight of the solid detergent;
- and
- (c) between about 2% and about 50% water by weight of the hydrated solid detergent composition;
- (d) wherein the composition is a solid block having a mass of at least 1 kg and having a growth exponent of less than about 3%, and
- (e) wherein the hydrated solid detergent composition is phosphorus-free and free of anionic surfactant.
