Claims18
An absorbent composition comprising:
- a hydrogel-forming polymeric material;
- and
- a magnetically-responsive material selected from the group consisting of ferrimagnetic materials and superparamagnetic materials wherein the magnetically-responsive material is present in the absorbent composition in an amount effective to result in the absorbent composition being magnetically responsive when in a magnetic field and wherein the absorbent composition remains substantially unmagnetized when a magnetic field is absent.
A disposable absorbent product comprising a liquid-permeable topsheet, a backsheet, and an absorbent structure positioned between the topsheet and the backsheet, wherein the absorbent structure comprises an absorbent composition comprising a hydrogel-forming polymeric material and a magnetically-responsive material selected from the group consisting of ferrimagnetic materials and superparamagnetic materials, and wherein the magnetically-responsive material is present in the absorbent composition in an amount effective to result in the absorbent composition being magnetically responsive when in a magnetic field and wherein the absorbent composition remains substantially unmagnetized when a magnetic field is absent.
