Abstract: An absorbent article is disclosed that has various leak-proof features. The absorbent article, for instance, includes containment flaps that hold body exudates within the garment. The containment flaps are attached to the absorbent article by a plurality of bond lines at each end of the containment flaps. In order to restrict fluids from flowing between the bond lines, the containment flaps are further bonded at each end by a transverse bond pattern. In one embodiment, the transverse bond pattern can be formed from ultrasonic point bonds. The transverse bond patterns not only restrict leaks but also is aesthetically pleasing.

Abstract: A water-dispersible injection-moldable composition includes a water-dispersible polymer, polyethylene glycol (PEG), plasticizer, and a hydrophobic polymeric component, wherein the composition has a melt flow index of 5-180. The water-dispersible polymer can be partially-hydrolyzed polyvinyl alcohol (PVOH) or ethylene-vinyl alcohol copolymer. The hydrophobic polymeric component can be a colorant within an ethylene matrix, polyethylene, a degradation product of glycerin/PVOH, erucamide, or poly(dimethyl siloxane). The plasticizer can be glycerin. The composition is flushable according to Guidance Document for Assessing the Flushability of Nonwoven Consumer Products (INDA and EDANA, 2006); Test FG 522.2 Tier 2—Slosh Box Disintegration Test.

Abstract: Superabsorbent particles have a median size of from about 50 to about 2,000 micrometers and contain a porous network that includes a plurality of nanopores having an average cross-sectional dimension of from about 10 to about 500 nanometers, wherein the superabsorbent particles exhibit a Vortex Time of about 80 seconds or less and a free swell gel bed permeability (GBP) of 5 darcys or more, of 10 darcys or more, of 20 darcys or more, of 30 darcys or more, of 60 darcys or more, or of 90 darcys or more. A method for forming such superabsorbent particles includes forming a composition that contains a superabsorbent polymer and a solvent system; contacting the composition with a non-solvent system to initiate formation of the porous network through phase inversion; removing non-solvent from the composition; and surface crosslinking the superabsorbent particles.
