The present invention provides a superabsorbent material which comprises a combination of: (1) an anionic superabsorbent in which from 20 to 100 % of the functional groups are in free acid form, and (2) a cationic superabsorbent in which from 20 to 100 % of the functional groups in basic form, the cationic superabsorbent being based on a polysaccharide or a polymer of units of a monomer of formula (I) wherein R1 and R2 which may be the same or different, are each organic radicals which do not adversely affect the properties of the polymer and X is a suitable anion. The combination is particularly effective as a superabsorbent in the case of electrolyte containing solutions such as menses and urine.
