Abstract

A surgical scrub includes a polyurethane foam sponge impregnated with a composition which includes iodine, iodide and a nonionic surfactant in a polar vehicle. The scrub may be attached to a plastic handle and may be supplied along with other optional scrubbing items in a package wrapped in plastic film.

Claims

1. A surgical scrub comprising a polyurethane sponge and a germicidal composition impregnated in said sponge, said composition comprising iodine, iodide, a polar vehicle and at least 12% of a nonionic surfactant when the composition if essentially water free and at least 21% of said nonionic surfactant when the composition includes water.

2. The scrub of claim 1 wherein the percentage of said iodine in the composition is about 0.5 to 1.5%.

3. The scrub of claim 1 wherein the percentage of said iodide is about 0.5 to 1.0%.

4. The scrub of claim 1 wherein said nonionic surfactant is selected from the group consisting of a polyoxyethylene sorbitan, polyoxyethylene-polyoxypropylene polyol and an alkylphenoxypolyoxyethylene alcohol.

5. The scrub of claim 1 wherein said polar vehicle is selected from the group consisting of an alcohol, a glycol, a liquid polyalkyleneglycol, a liquid alkyl ether or ester of a polyalkyleneglycol, a mixture thereof and a mixture thereof containing water.

6. The scrub of claim 1 further comprising a molded polymeric handle having said sponge attached thereto.
