Abstract

A non-irritating multi-ply absorbent article (110) made by treating an inner surface (122) with one or more antimicrobial agents (140) and treating the one or more outer surfaces (121) with one or more siloxane compositions (130), and methods of making and using the same. The antimicrobial agent will remain confined to the inner portion of the absorbent article, thereby preventing irritation to the user, and the siloxane treated ply(s) will provide a pleasing, soothing, non-irritating tactile quality. In one embodiment, the siloxane composition comprises an amine-modified polysiloxane, in which case the product will also entrap any absorbed fluid, holding it in contact with the antimicrobial agent, and preventing it from wetting through the product and contacting the user.

Claims (20)

1. A non-irritating, anti-microbial, mufti-ply absorbent article comprising:
a plurality of plies, at least one of said plies defining an outer ply;
at least one of said plies having a surface defining an inner surface;
at least one siloxane composition applied to at least a portion of said at least one outer ply; and an antimicrobially effective amount of at least one antimicrobial agent applied to said at least one inner surface.
2. The multi-ply absorbent article of claim 1, wherein said plurality of plies comprises three plies.
3. The multi-ply absorbent article of claim 2, wherein said three plies define two outer plies and an inner ply, respectively, and wherein a surface on said inner ply defines said inner surface.
4. The multi-ply absorbent article of claim 2, wherein said three plies define an outer ply, an inner ply, and a liquid-impermeable base ply, respectively, and wherein a surface on said inner ply defines said inner surface.
5. The multi-ply absorbent article of claim 2, wherein said plurality of plies comprises two plies.
6. The multi-ply absorbent article of claim 1, wherein said at least one siloxane composition comprises at least one polysiloxane.
7. The multi-ply absorbent article of claim 6, wherein said at least one polysiloxane comprises at least one amine-modified polysiloxane.
8. The multi-ply absorbent article of claim 7, wherein said at least one amine-modified polysiloxane is selected from the groups consisting of compounds having the formula:

14. An absorbent article comprising:
a first outer ply, an inner ply, and a second outer ply;
at least one siloxane composition applied to an outward surface of said first and second outer plies; and an antimicrobially effective amount of at least one antimicrobial agent applied to said inner ply.
15. The absorbent article of claim 14, wherein said at least one siloxane composition comprises at least one amine-modified polysiloxane.
16. The absorbent article of claim 15, wherein said at least one antimicrobial agent comprises at least one carboxylic acid.
17. A method for inhibiting the transfer of illness comprising:
providing a multi-ply absorbent article comprising a plurality of plies, at least one of said plies defining an outer ply; at least one of said plies having a surface defining an inner surface; at least one siloxane composition applied to at least a portion of said at least one outer ply; and an antimicrobially effective amount of at least one antimicrobial agent applied to said at least one inner surface;
contacting a fluid containing microbes with said absorbent article;
absorbing said fluid within said absorbent article; and entrapping said fluid in contact with said antimicrobial agent within said absorbent article.
18. The method of claim 17, wherein said fluid is a nasal discharge.
19. The method of claim 17, wherein said antimicrobial agent comprises at least one virucide.
20. The method of claim 17, wherein said at least one siloxane composition comprises at least one amine-modified polysiloxane.
