Patent

CA 2371328

The invention concerns an oxidising aqueous composition useful in particular for disinfection, hygiene and depollution purposes, and for surface treatment (particularly a metal surface to be stripped and/or passivated), and said composition, containing in water hydrogen peroxide, a RCO2H/RCO3H mixture (wherein R is a C1-C6 aliphatic radical with linear or branched hydrocarbon chain, saturated or unsaturated), a stabilising agent which is an acid and, as the case may be, Ag+ ions. The invention is characterised in that it contains ions of at least one metal M which are ions of AgII, AgIII, VV, NbV, TaV, MoVI, WVI, CoIII, InIII or TlIII. Advantageously, said composition can be in gel form. The invention also concerns the method for preparing said composition.

La présente invention concerne une composition aqueuse oxydante, qui est utile notamment dans le domaine de la désinfection, de l'hygiène et de la dépollution, d'une part, et dans le domaine du traitement du surface (en particulier une surface métallique pour son décapage et/ou sa passivation), d'autre part, ladite composition, qui contient dans le l'eau du peroxyde d'hydrogène, un mélange RCO¿2?H/RCO¿3?H (ou R est un reste aliphatique en C¿1?-C¿6? à chaîne hydrocarbonée linéaire ou ramifiée, saturée ou insaturée), un agent stabilisant qui est un acide, et, le cas échéant, des ions Ag?+¿, étant caractérisée en ce qu'elle renferme des ions d'au moins un métal M qui sont des ions de Ag?II¿, Ag?III¿, V?V¿, Nb?V¿, Ta?V¿, Mo?VI¿, W?VI¿, Co?III¿, In?III¿ ou T1?III¿. De façon avantageuse cette composition pourra se présenter sous la forme d'un gel. L'invention concerne également le procédé de préparation de ladite composition.
