Patent

CA 2413088

An object of the present invention is to provide safe preservatives by combining components widely used as additives of aqueous liquids. Preferred preservatives are obtained by combining boric acid and/or borax, ethylenediaminetetraacetic acid or a salt thereof and polyvinyl pyrrolidone. Preservation effects can be enhanced by further combining cellulosic polymers with the preservatives.

L'invention vise à produire des agents aseptiques extrêmement fiables par combinaison de composés utilisés communément comme additifs dans des préparations liquides aqueuses. Des agents aseptiques favorables peuvent être obtenus par utilisation combinée d'acide borique et/ou de borax, d'acide d'éthylènediaminetétra-acétique ou de ses sels et de pyrrolidone polyvinylique. L'effet aseptique peut être potentialisé par utilisation complémentaire de polymères de cellulose.
