Patent number: 6517849Abstract: This application relates to antiviral tissue paper comprising pyrrolidone carboxylic acid as an antiviral agent. When added to tissue paper pyrrolidone carboxylic acid has the ability to kill certain strains of viruses which come into contact with the tissue. In addition to its antiviral efficacy, pyrrolidone carboxylic acid tends to be mild to the skin thus mitigating the potential for skin irritation. Furthermore, upon transfer to the skin, pyrrolidone carboxylic acid assists in retention of the natural moisture of the skin while continuing to kill deleterious viruses.Type: GrantFiled: September 12, 2000Date of Patent: February 11, 2003Assignee: The Procter & Gamble CompanyInventors: Geoffrey Eugene Seger, Kimberly Ann Biedermann, Kamilah Apewaiye Gbadamosi, Stephen Robert Kelly, Paul Thomas Weisman
