The present invention relates to a process for the preparation of a solution comprising a first peroxy acid comprising performic acid and a second peroxy acid, said process comprising forming a carboxylic acid solution comprising a first carboxylic acid comprising formic acid, a second carboxylic acid and hydrogen peroxide, wherein the amount of formic acid is from 0.5 to 20% by weight of the amount of the second carboxylic acid, and allowing the components to react to form a solution comprising performic acid and said second peroxy acid, the amount of peroxy acids being at least 5% by weight. The invention also relates to a storable solution comprising performic acid and said second peroxy acid. The solution can be used as a disinfecting agent for controlling micro-organisms.
A storable solution comprising a first peroxy acid comprising performic acid, a second peroxy acid, a first carboxylic acid comprising formic acid, a second carboxylic acid comprising acetic acid, hydrogen peroxide, and a stabilizer, the total amount of formic acid and performic acid being from 0.5 to 20% by weight of the total amount of the second carboxylic acid and the second peroxy acid, the molar ratio of the peroxy acids and carboxylic acids to hydrogen peroxide being 2:1 to 8:1, and the total amount of peroxy acids being at least 5% by weight.
