Tinted antiseptic solutions having improved stability
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.
1. An antiseptic solution comprising:

about 0.01% to about 0.15% w/v of an anionic tinting agent; and
a solvent,
wherein the polymer is selected from the group consisting of 2-propenoic acid, 2-methyl-, polymer with butyl 2-propenoate and methyl 2-methyl-2-propenoate and 2-propenoic acid, 2-methyl-, 2-methylpropyl ester, polymer with 2-propenoic acid and N-(1,1,3,3tetramethylbutyl)-2-propenamide, and
the cationic antiseptic agent, the film forming polymer, and the anionic tinting agent each remain solubilized within the solution for about 1 hour or more at 25° C. and 60% relative humidity.
2. The antiseptic solution of claim 1 , wherein the cationic antiseptic agent, the film forming polymer, and the anionic tinting agent each remain solubilized for about 24 hours or more at 25° C. and 60% relative humidity.
3. The antiseptic solution of claim 1 , wherein the cationic antiseptic agent, the film forming polymer, and the anionic tinting agent each remain solubilized for about 1 month or more at 25° C. and 60% relative humidity.
4. The antiseptic solution of claim 1 , wherein the cationic antiseptic agent, the film forming polymer, and the anionic tinting agent each remain solubilized for at 3 month or more at 25° C. and 60% relative humidity.
5. The antiseptic solution of claim 1 , wherein the antiseptic agent comprises an octenidine salt or chlorhexadine salt.
6. The antiseptic solution of claim 1 , wherein the antiseptic agent comprises octenidine dihydrochloride or clorhexadine gluconate.
7. The antiseptic solution of claim 1 , wherein the anionic tinting agent comprises an agent selected from the group consisting of Blue No. 1, Blue No. 2, Green No. 3, Red No. 3, Red No. 40, Yellow No. 5, Yellow No. 6, Yellow No. 8, Orange No. 4, and combinations thereof.
