Abstract: The present invention relates to superabsorbent polymer particles with improved surface cross-linking and their use in absorbent articles. The superabsorbent polymer particles of the present invention comprise a water-absorbing resin and the reaction product of a radiation activatable surface cross-linker wherein the reaction product of the radiation activatable surface cross-linker is present at surfaces of the superabsorbent polymer particles. The radiation activatable surface cross-linker comprises at least two radiation activatable groups R, which are covalently bound to each other or to at least one spacer group S. Moreover, the invention relates to a process for making these superabsorbent polymer particles.
Abstract: An absorbent article, such as a diaper, containing cuffs with a skin care composition disposed thereon. The skin care composition disposed on the cuffs is transferable to the wearers skin by normal contact and/or wearer motion and/or body heat. The cuffs are at least partially assembled using an oil resistant adhesive that is both material friendly and process friendly.

Abstract: An interlabial absorbent structure is disclosed. The interlabial absorbent structure comprises a pair of absorbent panels that are sufficiently flexible such that the panels can, at least partially, conform to the walls of a wearer's interlabial space. The panels are joined by an isthmus which is positioned farthest into a wearer's interlabial space when the interlabial absorbent product is worn. Alternative embodiments of the isthmus are also described which direct bodily fluids that are deposited thereon along the longitudinal length of the interlabial absorbent structure.
