Abstract
A solid composition includes a polysaccharide hybrid polymer composition and a hydratable salt. In one embodiment, the polysaccharide hybrid polymer composition includes a polysaccharide residue present in an amount from approximately 5% to 90% by weight of the polysaccharide hybrid polymer composition and a residue of at least one ethylenically unsaturated monomer present in an amount from approximately 10% to 75% by weight of the polysaccharide hybrid polymer composition.
Claims25
A solid detergent composition comprising:
- a polysaccharide hybrid polymer composition present in an amount from about 1% to about 20% by weight of the solid detergent composition, wherein the polysaccharide hybrid polymer composition comprises:
- residue of a polysaccharide present in an amount from about 5% to about 90% by weight of the polysaccharide hybrid polymer composition;
- and
- residue of at least one ethylenically unsaturated monomer present in an amount from about 10% to about 75% by weight of the polysaccharide hybrid polymer composition;
- a hydra table salt present in an amount of about 40% or greater by weight of the solid detergent composition;
- and
- water present in an amount of about 2% or greater by weight of the solid detergent composition.
A method of forming a hydrate solid, the method comprising:
- mixing water and a polysaccharide hybrid polymer composition to form a liquid premix, wherein the polysaccharide hybrid polymer composition includes a polysaccharide and at least one ethylenically unsaturated monomer or salts thereof;
- and
- adding the liquid premix to at least one hydratable salt to form a mixture;
- and
- forming a hydrate solid from the mixture.
A method of cleaning a substrate, the method comprising:
- mixing water with a solid composition to form a use solution, the solid composition comprising:
- a polysaccharide hybrid polymer composition present in an amount from about 1% to about 20% by weight of the solid composition, the polysaccharide hybrid polymer composition comprising residue of a polysaccharide present in an amount from about 5% to about 90% by weight of the polysaccharide hybrid polymer composition and residue of at least one ethylenically unsaturated monomer present in an amount from about 10% to about 75% by weight of the polysaccharide hybrid polymer composition;
- a hydra table salt present in an amount of about 40% or greater by weight of the solid composition;
- and
- water present in an amount of about 2% or greater by weight of the solid composition;
- and
- contacting the substrate with the use solution.
