A method of sterilizing a material, said method comprising the steps of: a) providing a sterilizing composition comprising (i) peracetic acid and (ii) a stabilizer selected from the group consisting of citric acid, isocitric acid, aconitic acid and propane-1,2,3-tricarboxylic acid; b) introducing such sterilizing composition into a hot gaseous stream to produce a peracetic acid vapor; and c) contacting such peracetic acid vapor with the material to be sterilized. The use of such an organic acid stabilizer results in an unexpected reduction in the amount of residue deposited on the heating surface employed to vaporize the sterilizing composition.

Sterilization method

The invention relates to anti-microbial compositions useful against a wide range of microorganisms undesirable on a wide variety of materials, including food, food contact and non-food contact surfaces, and surfaces in industrial, recreational, health care, and other institutional environments. More particularly, the anti-microbial compositions comprise peracetic acid in combination with a) citric acid or a salt and b) salicylic acid or a salt in aqueous solution.
