Abstract
An antimicrobial skin composition comprised of an antimicrobial agent, an alcohol, one or more pH sensitive viscosity builders, a plasticizer and water. Preferably, the viscosity builders of the present invention are comprised of pH sensitive methacrylic polymers which are alcohol compatible and have pH controlled water solubility. The composition combines the advantages of an antimicrobial agent and an alcohol, and has a viscosity of from 100 cp to 1,000. This viscosity is sufficiently low for purposes of dispensing and applying the preparation, yet sufficiently high to cause the solution to remain in the area of the wound and not flow away or pool under the patient. The preparation further forms a water-resistant film that is difficult to remove during wound irrigation, but can be easily removed upon completion of the procedure. In addition, the preparation is fast drying so as to take advantage of the fast high initial kill properties of alcohol. Finally, with the addition of a plasticizer (such as PEG 400), the film formed by the composition resists flaking in medical procedures requiring substantial skin manipulation.
