A highly absorbent material which is substantially dry and non-sticky to the touch in the swollen state being a substantially water-insoluble cross-linked gelatinised starch, in which the degree of substitution of the cross-linking groups is 0.001 to 0.02, which is substituted by ionic groups which are attached to the starch by ether linkages and which groups are associated with counterions selected from mono- and divalent counterions, and which has a urine retention value of at least 8 g/g.
