1. A polysaccharide composition comprising a dry blend of (a) a particulate aqueous liquid soluble, polysaccharide or polysaccharide derivative having essentially no cross-linkages which forms substantial amounts of soft lumps, nodules or other agglomerations upon addition to water at ambient conditions and (b) a particulate polysaccharide or polysaccharide derivative being sufficiently cross-linked such that the cross-linked polysaccharide or polysaccharide derivative does not form soft lumps, nodules or other agglomerations upon its addition to water;

  • said uncross-linked polysaccharide or derivative and cross-linked polysaccharide or derivative being employed in amounts such that upon the composition'"'"'s dispersion and subsequent dissolution in an aqueous solution at ambient temperature, the uncross-linked polysaccharide or derivative thereof does not form substantial amounts of soft lumps, nodulus or other agglomerations and the viscosity of the aqueous liquid is increased at a sufficient rate that the cross-linked polysaccharide is maintained in dispersion without significant amounts thereof settling prior to dissolution.
