Estimating the term…
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.
An aqueous oxidizing composition (I) which is useful in the field of disinfection, hygiene and decontamination, and in the field of treating, cleaning, stripping and/or passivating surfaces, said composition, which comprises, in water, hydrogen peroxide, an RCO2H/RCO3H mixture in which R is a C1-C6 aliphatic residue containing a linear or branched, saturated or unsaturated hydrocarbon-based chain, and a stabilizer which is an acid and, optionally, Ag+ ions, being characterized in that it contains ions of at least one metal M selected from the group consisting of AgII, AgIII, VV, NbV, TaV, MoVI, WVI, CoIII, InIII and TlIII ions, the source L of the metal M, which gives AgII ions or AgII+AgIII ions, wherein starting with 100 g of silver and 1 liter of demineralized water, the concentration of Ag++Ag2+ or Ag++Ag2++Ag3+ ions in the resulting solution gives a redox potential of greater than 1,000 mV.
