Abstract

See full text

The present invention relates to absorbent articles, typically for feminine protection, comprising a topsheet, a backsheet, an absorbent element positioned between the topsheet and the backsheet, and at least a fluid acquisition/distribution layer. The absorbent article also comprises edge barrier elements for intercepting fluids. The edge barrier elements comprise a liquid absorbent thermoplastic composition comprising a polymeric base material having particles of water-insoluble water-swellable absorbent material dispersed therein, and are comprised between the absorbent core and the at least one fluid acquisition/distribution layer.
