Abstract

The impregnation of a foam rubber, or similar polymeric material, insole with an effective antibacterial and antifungal agent along with a deodorant provides a simple, clean source of active ingredients for curative and prophylactic treatment of infections of the feet and reduces odors during the course of the treatment. The agent of choice in such a product must be stable to the conditions of use and be sufficiently non-volatile to be retained in the insole over a period of days or weeks.

Claims

1. A foam rubber insole comprising from about 0.5% to about 5% by weight of tris(para-chloro-metaxylenol)borate, from about 0% to about 10% by weight of a deodorizing agent, and from about 85% to about 99.5% by weight of a cured latex.

2. The foam rubber insole of claim 1 which comprises from about 1% to about 10% by weight of a deodorizing agent.

3. The foam rubber insole of claim 1 or 2 wherein said deodorizing agent is sodium bicarbonate.

4. The foam rubber insole of claim 1 or 2 wherein said cured latex is selected from the group consisting of a cured rubber latex, a cured polyurethane-latex combination, a cured polypropylene-latex combination, and a butyl foam-latex combination.

5. The foam rubber insole of claim 3 wherein said cured latex is selected from the group consisting of a cured rubber latex, a cured polyurethane-latex combination, a cured polypropylene-latex combination, and a cured butyl foam-latex combination.

6. A method for the treatment of microbial infections, including athletes foot, on a human foot by inserting a foam rubber insole comprising from about 0.5% to about 5% by weight of tris(para-chloro-meta-xylenol)borate, from about 0% to about 10% by weight of a deodorizing agent, and from about 85% to about 99.5% by weight of a cured latex into a shoe and subsequently contacting said foot with said insole.

7. The method of claim 6 wherein said foam rubber insole comprises from about 1% to about 10% by weight of a deodorizing agent.

8. The method of claim 6 or 7 wherein said deodorizing agent is sodium bicarbonate.

9. A method of inhibiting the growth of bacteria or fungi in a shoe by inserting a foam rubber insole comprising from about 0.5% to about 5% by weight of tris(para-chloro-meta-xylenol)borate, from about 0% to about 10% by weight of deodorizing agent, and from about 85% to about 99.5% by weight of a cured latex into said shoe.

10. The method of claim 9 wherein said foam rubber insole comprises from about 1% to about 10% by weight of a deodorizing agent.

11. The method of claim 9 or 10 wherein said deodorizing agent is sodium bicarbonate.
