Abstract
An antiseptic solution including, a cationic antiseptic agent, a film forming polymer, an anionic tinting agent, and a solvent, wherein the cationic antiseptic agent, the film forming polymer and the anionic tinting agent each remain solubilized within the solution for greater than about 1 hour at 25° C. and 60% relative humidity. The antiseptic agent is preferably octenidine dihydrochloride or chlorhexadine gluconate. The film forming polymer is preferably an acrylate polymer. The solvent is preferably ethanol, isopropanol, and n-propanol. When a drape is adhered to a dried surgical film via the antiseptic solution, the force required to peel the drape from the surgical film is at least about 105 g/25 mm.
