Abstract

A process for making a stable chemical complex of iodine, an iodide ion and a dermatologically acceptable room temperature tacky pressure-sensitive adhesive which is substantially free of acidic components. The resulting composition exhibits broad-spectrum antimicrobial activity when placed in contact with mammalian skin.

Claims

1. In a process for making a composition which exhibits antiseptic broad-spectrum antimicrobial activity when placed in contact with the skin, the improvement comprising forming a solution of an iodide, a solvent and iodine, and reacting said solution with a dermatologically acceptable pressure-sensitive adhesive.

2. In a composition which exhibits antiseptic broad-spectrum antimicrobial activity when placed in contact with the skin, the improvement comprising a stable chemical complex of an iodide, iodine and a dermatologically acceptable pressure-sensitive adhesive.

3. The composition of claim 2 wherein said dermatologically acceptable pressure-sensitive adhesive is substantially free of acidic components.

5. The composition of claims 2 and 4 wherein said pressure-sensitive adhesive is a copolymer comprising isooctyl acrylate and N-vinyl-pyrrolidone.

4. In a flexible sheet material having attached thereto a dermatologically acceptable pressure-sensitive adhesive, the improvement comprising said dermatologically acceptable, pressure-sensitive adhesive being a stable chemical complex of an iodide, iodine and a dermatologically acceptable pressure-sensitive adhesive.

6. The sheet material and adhesive of claim 4 in the form of a medical device.

7. The sheet material and adhesive of claim 4 in the form of a tape.

8. The sheet material and adhesive of claim 4 in the form of a drape.
