Patent ID: 7235252

Claim:
A system for a fast-rate preparation just before use of organic peroxyacids, in a hydroalcoholic environment, by mixing at a temperature lower than 40° C., a first reactant and a second reactant, kept separate from each other during storage, to obtain an activated solution, wherein: said first reactant is an activator in solid or liquid state at a temperature from 5° C. to 45° C., is lipophilic, and comprises at least one acyl donating group, and said second reactant is in liquid state, at least in the temperature range from 5° C. and 40° C., is hydrophilic, and comprises a peroxide anion source in a concentration such as to provide at least 10-fold molar excess of peroxide with respect to the stoichiometric amount of said at least one acyl-donor, a biocidal agent comprising at least one C 1 –C 18 linear or branched aliphatic and/or aromatic alcohol, and a stabilizing buffer component suitable for keeping said second reactant at a desired pH value.
