Abstract

The present invention relates to a personal care absorbent article comprising at least two substrates each having an internal and external surface, wherein at least one substrate is a fluid permeable bodyside substrate selected from spunbond, meltblown, coform, airlaid, bonded-carded web, spunlace materials and combinations thereof; at least one substrate is an impermeable backsheet; and an absorbent core disposed in between said substrates; wherein at least the external surface of at least one substrate has applied to it a benefit agent selected from an additive composition wherein said additive composition is a polymer dispersion selected from polyolefin dispersions, polyisoprene dispersions, polybutadiene-styrene block copolymer dispersions, latex dispersions, polyvinyl pyrrolidone-styrene copolymer dispersions, polyvinyl alcohol-ethylene copolymer dispersions, and combinations thereof; an enhancement component selected from microparticles, expandable microspheres, fibers, additional polymer dispersions, scents, anti-bacterials, moisturizers, medicaments, soothers and combinations thereof; and combinations thereof.

Claims (20)

1 . A personal care absorbent article comprising at least two substrates each having an internal and external surface,

wherein at least one substrate is a fluid permeable bodyside substrate selected from spunbond, meltblown, coform, airlaid, bonded-carded web, spunlace materials and combinations thereof;

at least one substrate is an impermeable backsheet; and

an absorbent core disposed in between said substrates;

wherein at least the external surface of at least one substrate has applied to it a benefit agent selected from an additive composition wherein said additive composition is a polymer dispersion selected from polyolefin dispersions, polyisoprene dispersions, polybutadiene-styrene block copolymer dispersions, latex dispersions, polyvinyl pyrrolidone-styrene copolymer dispersions, polyvinyl alcohol-ethylene copolymer dispersions, and combinations thereof; an enhancement component selected from microparticles, expandable microspheres, fibers, additional polymer dispersions, scents, anti-bacterials, moisturizers, medicaments, soothers and combinations thereof; and combinations thereof.

2 . The personal care article of claim 1 wherein said fluid permeable bodyside substrate has a basis weight from about 5 gsm to about 200 gsm.

3 . The personal care article of claim 1 wherein the benefit agent is frothed and bonded to the external surface of at least one substrate through a creping process.

4 . The personal care absorbent article of claim 1 wherein the external surface of at least one substrate is applied with from about 3% to about 20%, by weight of the substrate, of a benefit agent.

5 . The personal care absorbent article of claim 1 wherein the additive composition may be applied onto the external surface of at least one substrate at a level from about 50 mg/m 2 to about 50,000 mg/m 2 .

6 . The personal care article of claim 1 wherein the benefit agent is an additive composition comprising from about 10% to about 32%, by weight of the benefit agent, a polyolefin dispersion.

7 . The personal care absorbent article of claim 1 wherein the benefit agent is an enhancement component.

8 . The personal care absorbent article of claim 6 wherein the benefit agent is a combination further comprising an enhancement component that is added to the polymer dispersion in an amount from about 0.5% to about 30%, by weight of the benefit agent.

9 . The personal care absorbent article of claim 1 wherein the additive composition is a water-insoluble polyolefin copolymer selected from ethylene-acrylic acid, polyethylene-octene copolymer, and combinations thereof.

10 . The personal care absorbent article of claim 1 wherein the additive composition is selected from a synthetic water-soluble polymer, a natural water-soluble polymer and mixtures thereof.

11 . The personal care article of claim 1 wherein said fluid permeable bodyside substrate has a saline or menses simulant fluid absorbent capacity greater than from about 1 g/g to about 10 g/g.

12 . The personal care article of claim 1 wherein said fluid permeable bodyside substrate is provided with a plurality of apertures extending from said external surface through said internal surface for fluid passage to said absorbent core

13 . The personal care article of claim 1 wherein said article is a product selected from a feminine hygiene product, a diaper, a training pant, and an adult incontinence product.

14 . The personal care article of claim 7 wherein said article is a product selected from a feminine hygiene product, a diaper, a training pant, and an adult incontinence product.

15 . The personal care article of claim 11 wherein said article is a product selected from a feminine hygiene product, a diaper, a training pant, and an adult incontinence product.

16 . The personal care article of claim 1 wherein the benefit agent does not leave or transfer from the fluid permeable bodyside substrate to a user.
