  • Publication number: 20140309606
    Abstract: The present invention relates to an absorbent article containing a topsheet; backsheet; an absorbent core disposed between the topsheet and backsheet, the absorbent core comprising a particulate superabsorbent polymer composition having improved stability comprising a polymer comprising from about 0.01 wt % to about 5 wt % of a neutralized aluminum salt solution applied to the surface of a particulate superabsorbent polymer composition; wherein an aqueous solution of the neutralized aluminum salt has a pH value from about 5.5 to about 8 and the particulate superabsorbent polymer composition has an original Free Swell Gel Bed Permeability (FSGBP) of about 20×10?8 cm2 to about 200×10?8 cm2 and a compressibility of from about 1.30 cm2/N to about 4 cm2/N prior to subjecting the particulate superabsorbent polymer composition to a Processing Test; and subsequent to subjecting to the Processing Test, the particulate superabsorbent polymer composition has a permeability stability index of from about 0.60 to about 0.

  • Patent number: 8079994
    Abstract: In one aspect, the present invention relates to an array of gender-specific disposable absorbent articles having gender-specific containment flaps. In one embodiment, the array of articles comprises a first disposable absorbent article adapted to be worn by males, and a second absorbent article adapted to be worn by females. The first disposable absorbent article comprises a first pair of containment flaps, and the second disposable absorbent article comprises a second pair of containment flaps. The first pair of containment flaps differs from the second pair of containment flaps in at least one structural feature. In particular embodiments, the structural feature that differs is selected from the group consisting of flap active length, flap active-portion longitudinal position, flap tension, flap height, distal-to-distal spacing, and proximal-to-proximal spacing.
