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.
La présente invention concerne un papier de soie antiviral comportant de l'acide carboxylique de pyrrolidone en tant qu'agent antiviral. Lorsqu'il est additionné à du papier de soie l'acide carboxylique de pyrrolidone présente une activité permettant de tuer certaines souches de virus venant en contact avec le papier. En sus de son efficacité antivirale, l'acide carboxylique de pyrrolidone possède une douceur vis-à-vis de la peau permettant ainsi d'atténuer l'irritation cutanée. Par ailleurs, lors de son transfert sur la peau, l'acide carboxylique de pyrrolidone aide à la rétention de l'humidité naturelle de la peau tout en continuant à tuer les virus nuisibles.
