Abstract
Disclosed is an absorbent foam that exhibits desirable softness and flexibility properties yet is highly absorbent. In one embodiment, the absorbent foam comprises a water-swellable, water-insoluble polymer wherein the absorbent foam exhibits a Free Swell value of at least about 10 grams of liquid per gram of absorbent foam and a Softness value that is less than about 30 grams of force per gram per square meter of absorbent foam. In a second embodiment, the absorbent foam has an average cell size of the cells in the absorbent foam between about 10 microns to about 100 microns and an average wall thickness of the cells in the absorbent foam between about 0.1 micron to about 30 microns. Such an absorbent foam may be used in a disposable absorbent product intended for the absorption of fluids such as body fluids.
