Improved skin-adhesive compositions for bonding a substrate, such as an absorbent article, to skin are disclosed. More particularly, the skin-adhesive composition has an improved, yet gentle, adhesion to the skin of a user, while maintaining strong, effective bonding to various inanimate, non-skin substrates. In one embodiment, the skin-adhesive composition can provide one or more skin benefit agents to the user. The skin-adhesive composition may be applied to an absorbent article, such as a panty-liner, sanitary napkin, or an incontinence article, for directly adhering the article to the skin of a user.

1. An absorbent article comprising a fluid impermeable substrate having a body-facing surface and a garment-facing surface, the body-facing surface having a skin-adhesive and absorbent gel composition thereon for adhering the substrate directly to a wearer and for absorbing bodily fluids, the gel composition comprises a hydrogel composed of monomers selected from the group consisting of N-vinyl pyrrolidone, hydroxyethyl methacrylate, methacrylic acid or its salt, styrene sulfonic acid or its salt, potassium sulfopropyl acrylate, dimethyl acrylamide, dimethyl amino ethyl methacrylate or its quaternary salt derivative, acrylamido methyl propane sulfonic acid or its salt and mixtures thereof, wherein the gel composition further comprises an adhesion modifier dispersed within the gel composition, wherein the adhesion modifier is selected from allyl methacrylates crosspolymer, allyl methacrylate/glycol dimethacrylate crosspolymer, lauryl methacrylate/glycol dimethacrylate crosspolymer and derivatives thereof, wherein the hydrogel is intertwined with a fibrous web, and wherein the ratio of the hydrogel to the fibrous web is from about 30:1 to about 100:1 by basis weight. 2. The absorbent article as set forth in claim 1, wherein the skin-adhesive and absorbent gel composition includes from about 5% to about 20% by total weight of the composition adhesion modifier. 3. The absorbent article as set forth in claim 1, wherein the skin-adhesive and absorbent gel composition is capable of absorbing at least 20% of its weight in water. 4. The absorbent article as set forth in claim 1, wherein the skin-adhesive and absorbent gel composition is capable of absorbing at least 100% of its weight in water. 5. The absorbent article as set forth in claim 1, wherein the skin-adhesive and absorbent gel composition is capable of absorbing at least 1000% of its weight in water. 6. The absorbent article as set forth in claim 1, wherein the hydrogel is formed from a precursor composition comprising a monomer, initiator, a cross-linking agent and a solvent. 7. The absorbent article as set forth in claim 1, wherein the hydrogel has a three-dimensional cross-linked structure. 8. The absorbent article as set forth in claim 1, wherein the skin-adhesive and absorbent gel composition comprises a skin benefit agent, wherein the skin benefit agent is selected from the group consisting of antiperspirants, deodorants, skin moisturizers, humectants, pH modulators, soothing agents, antimicrobials, preservatives, film formers, and combinations thereof. 9. The absorbent article as set forth in claim 8, wherein the skin-adhesive and absorbent gel composition comprises from about 0.001% to about 60% by total weight of the composition of the skin benefit agent. 10. The absorbent article as set forth in claim 1, wherein the substrate is composed of a material selected from the group consisting of a polymeric film, polymeric foam, woven fabric, nonwoven fabric and knitted fabric. 11. The absorbent article as set forth in claim 1, wherein the skin-adhesive and absorbent gel composition defines a central portion and a peripheral portion wherein the peripheral portion is more adhesive to the skin of the wearer than the central portion. 12. The absorbent article as set forth in claim 11, wherein the central portion is more absorbent than the peripheral portion.
