Abstract
A composition includes an anionic polysaccharide hybrid polymer composition and 2-phosphonobutane-1,2,4-tricarboxylic acid. In one embodiment, the polysaccharide hybrid polymer composition includes a polysaccharide residue present in an amount from approximately 5% to approximately 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 approximately 75% by weight of the polysaccharide hybrid polymer composition.
