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.

Copper salts of ion exchange materials provide copper ions at levels suitable for use as an anti-infective agent. The copper salts of ion exchange materials may be formed using ether and ester derivatives of cellulose, such as carboxymethyl cellulose (CMC), ethylcellulose (EC), methylcellulose (MC), hydroxypropyl cellulose (HPC), hydroxypropyl methyl cellulose (HPMC), hydroxyethyl methyl cellulose (HEMC), cellulose acetate, and cellulose triacetate. Wound dressings having copper salts of ion exchange materials incorporated therein are also provided, and may be used to reduce the incidence of infection in wounds. The wound dressings may also be used to prevent infections in long-term wounds, such as those formed at wound drain, catheter, and ostomy entry sites. Copper salts of ion exchange materials may be used to kill microorganisms, and may optionally be used with additional anti-infective agents.

An applicator for reducing the concentration of unwanted chemicals such as para-chloroaniline (PCA) from an antiseptic solution includes an antiseptic solution in amount sufficient to have an antimicrobial effect on a surface and at least one hydrophobic or hydrophilic material. The hydrophobic or hydrophilic material selectively removes undesired by-products from the antiseptic solution when the antiseptic solution contacts the hydrophobic or hydrophilic material. A method for selectively removing unwanted by-products from an antiseptic solution includes the steps of providing an antiseptic solution in amount sufficient to have an antimicrobial effect on a surface and contacting the antiseptic solution with at least one hydrophobic or hydrophilic material that selectively removes the unwanted by-products from the antiseptic solution.

Liquid applicator and method for reducing the concentration of by-products from antiseptic

Applicators and a method for reducing the concentration of unwanted chemicals, such as para-chloroaniline (PCA) from an antiseptic solution. More specifically, the applicator includes antiseptic solution in amount sufficient to be applied to a desired surface and to have an antimicrobial effect on the desired surface and a porous element. The porous element selectively removes undesired by-products from the antiseptic solution when the antiseptic solution contacts the at least one porous element.
