Abstract

The present invention provides a multiple, long-term use, antimicrobial glove. The glove is formed from one or more layers of material having a latex-based matrix with an antimicrobial agent, such as diiodomethyl-p-tolylsulfone, homogeneously incorporated therein. Optionally, the glove may also have additional antimicrobial agents incorporated therein. The glove of the present invention is capable of inhibiting molds and other microbes from proliferating on any surface of the glove, during both storage and use, which results in the prevention of malodor, discoloration, and degradation of the glove. Also, the glove of the present invention is believed to be capable of providing an antimicrobial effect to surfaces contacted by the antimicrobial glove.

Claims

1. An antimicrobial glove comprising:

a glove material; and

an antimicrobially effective amount of diiodomethyl-p-tolylsulfone homogeneously distributed throughout said glove material.

2. The glove of claim 1, wherein said diiodomethyl-p-tolylsulfone is about 0.001 wt. % to about 5 wt. % of the total weight of the glove.

3. The glove of claim 1, wherein said diiodomethyl-p-tolylsulfone is about 0.02 wt. % to about 0.5 wt. % of the total weight of the glove.

4. The glove of claim 1, wherein said glove material is selected from the group consisting of:

natural rubber, natural rubber latex, neoprene, polyvinyl chloride, nitrile, synthetic polymer, synthetic resin, synthetic rubber, acrylic-based polymer, and any mixtures thereof.

5. The glove of claim 2, wherein said glove material is selected from the group consisting of:

natural rubber, natural rubber latex, neoprene, polyvinyl chloride, nitrile, synthetic polymer, synthetic resin, synthetic rubber, acrylic-based polymer, and any mixtures thereof.

6. The glove of claim 2, wherein said glove material comprises about 50 wt. % to about 98 wt. % natural rubber latex, based on the total weight of the glove.

7. The glove of claim 1, wherein said glove material comprises about 50 wt. % to about 98 wt. % natural rubber latex, based on the total weight of the glove.

8. The glove of claim 1, wherein the glove is formed from one or more layers of said glove material.

9. The glove of claim 8, wherein at least one of said one or more layers of said glove material has an antimicrobially effective amount of diiodomethyl-p-tolylsulfone homogeneously distributed throughout.

10. The glove of claim 1, wherein the glove is formed from two or more layers of said glove material.

11. The glove of claim 10, wherein at least two of said two or more layers are formed from different glove materials.

12. The glove of claim 10, wherein at least two of said two or more layers are formed from the same glove material.

13. The glove of claim 12, wherein said same glove material in each of said two or more layers is present in different amounts.

14. The glove of claim 1, wherein the glove is formed from three or more layers of said glove material.

15. The glove of claim 14, wherein at least two of said three or more layers are formed from the same glove material.

16. The glove of claim 15, wherein said same glove material in each of said at least two layers is present in different amounts.

17. The glove of claim 1, further comprising at least one additional antimicrobial agent.

18. The glove of claim 17, wherein said at least one additional antimicrobial agent is selected from the group consisting of:

triclosan, fluorescent material, silver salt, biguanide, chlorohexidene salt, dextran sulfate, quaternary ammonium salt, benzalkonium, acriflavine, acridine dye, gentian violet, mercurochrome, extract of blue green algae, and any combinations thereof.

19. The glove of claim 1, wherein said glove material further comprises a component selected from the group consisting of one or more:

surfactants, cross-linkers, antidegradants, cure accelerators, activators, stabilizers, pigments, extenders, and any combinations thereof.

20. A method for forming an antimicrobial glove comprising the steps of:

(a) providing an aqueous dispersion of a glove material;

(b) incorporating a second dispersion having diiodomethyl-p-tolylsulfone in said aqueous dispersion of step (a), whereby a final dispersion is formed; and

(c) forming a glove from said final dispersion.

21. The method of claim 20, wherein said glove material is selected from the group consisting of:

natural rubber, natural rubber latex, neoprene, polyvinyl chloride, nitrile, synthetic polymer, synthetic resin, synthetic rubber, acrylic-based polymer, and any combinations thereof.

22. The method of claim 20, further comprising a step of incorporating at least one additional dispersion in said aqueous dispersion of step (a).

23. The method of claim 22, wherein said at least one additional dispersion comprises an antimicrobial agent selected from the group consisting of:

triclosan, fluorescent material, silver salt, biguanide, chlorohexidene salt, dextran sulfate, quaternary ammonium salt, benzalkonium, acriflavine, acridine dye, gentian violet, mercurochrome, extract of blue green algae, and any mixtures thereof.

24. The method of claim 20, wherein said glove material further comprises a component selected from the group consisting of one or more:

surfactants, cross-linkers, antidegradants, cure accelerators, cure activators, stabilizers, pigments, extenders, and any combinations thereof.
