In one aspect of the invention, the cationic modified starch is not substantially insoluble. In another aspect of the invention, the cationic modified starch is cross-linked by a cross-link-ing agent, wherein the cross-linking agent is reacted with the starch in concentration of from about 100 ppm to about 4000 ppm by weight of starch.
