  • Patent number: 8343525
    Abstract: An antiseptic cleaning agent, generally, comprising chlorhexidine acetate and a solvent, such as an alcohol and/or water. The chlorhexidine acetate acts as a highly effective biocide. Additionally, the chlorhexidine acetate allows the cleaning agent to dry without leaving a tacky residue. Where the cleaning agent comprises one or more alcohols, the alcohols may comprise any suitable alcohols, including lower alcohols having from 1 to 6 carbon atoms, such as ethanol and isopropanol. Where the ratio of ethanol to isopropanol may be from between about 1:1000 to about 1000:1. In addition to chlorhexidine acetate, the cleaning agent optionally comprises another non-alcohol biocide, such as triclosan. The cleaning agent can be used in any suitable manner. For instance, the cleaning agent may be impregnated in an absorbent material, such as a towelette, swabstick, or gauze. Additionally, the absorbent material may comprise a positively charged or a non-ionic substance, such as polypropylene or polyester.

  • Patent number: 5763412
    Abstract: An antimicrobial film forming surgical site preparation composition includes a film forming material and an antimicrobial agent soluble in a fugitive solvent. The composition when applied to the skin surface forms a substantially water insoluble, substantially tack-free flexible film adherent to the skin surface. The film is capable of releasably retaining the antimicrobial agent to substantially inhibit microbial growth on the skin surface. The film releases sufficient antimicrobial agent to substantially eliminate the microorganisms normally present on the skin surface to prepare the surface for the procedure and continues to release the antimicrobial agent during the procedure and subsequent wound healing. The composition can be easily washed from fabric and does not stain the fabric even where the fabric is treated with chlorine bleach. In addition, a smooth continuous film is formed without the use of a separate plasticizer.

  • Patent number: 5547662
    Abstract: A film forming composition for preparation of a skin surface as a surgical site includes a film forming material and a antimicrobial agent soluble in a fugitive solvent. The composition when applied to the skin surface forms a substantially water insoluble, substantially tack-free flexible film adherent to the skin surface. The film is capable of releasably retaining the antimicrobial agent to substantially inhibit microbial growth on the skin surface. The film releases sufficient antimicrobial agent to substantially eliminate the microorganisms normally present on the skin surface to prepare the surface for the procedure and continues to release the antimicrobial agent during the procedure and subsequent wound healing. A preferred embodiment of the composition includes at least one compound for providing a first color indicative of the skin surface area covered by the composition and develops a second color upon the substantial elimination of the fugitive solvent indicating that the site is ready.
