Abstract
A working disinfectant solution comprising peracetic acid and at least one surfactant, prepared by the dilution of either a single-part or two-part concentrate for use in the disinfection or sterilisation of reusable medical devices such as endoscopes. The working solution exhibits rapid wetting characterised by a dynamic surface tension of less than 50 mN/m at 250 ms and 46 mN/m at 500 ms.

A working disinfectant solution for the sterilisation or disinfection of a medical device comprising an aqueous dilution of a disinfectant concentrate, comprising:
- a. peracetic acid;
- and
- b. at least one surfactant,
- wherein said working disinfectant solution exhibits a dynamic surface tension less than about 50 mN/m at a surface age of 250 ms, and less than about 46 mN/m at a surface age of 500 ms, when measured by the Maximum Bubble Pressure method at 20-25° C.
A method of disinfecting or sterilizing a medical device, which method comprises contacting said medical device with a working disinfectant solution comprising an aqueous dilution of a disinfectant concentrate, comprising:
- a. peracetic acid;
- and
- b. at least one surfactant,
- wherein said working disinfectant solution exhibits a dynamic surface tension less than about 50 mN/m at a surface age of 250 ms, and less than about 46 mN/m at a surface age of 500 ms when measured by the Maximum Bubble Pressure method at 20-25° C.
