The standard NHS Clostridium difficile ( C.diff ) test EN 13704 test does not accurately reflect the efficacy of disinfectants currently test against C Diff.

NHS – Dudley Road Laboratories (A.P.Fraise and Tina Bradley) have developed a new more stringent testing method detailed for evaluating disinfectants against C Diff. The results below have been carried out using the New testing Method.( “A.P. Fraise et al Journal of Hospital Infection 89(2015) 2-15”). BluTest Laboratories Ltd – is a leading microbiology research organization who are the preferred testing facility for the NHS.

We have partnered with the University of the West of Scotland – UWS (Prof. Andrew Hursthouse and Dr.M Yassen) and they are currently producing stability and materials compatibility reports.

Our initial assessment is that the product will not irritate or sensitive skin, it will be compatible with the materials it is likely to come into contact with in a healthcare situation and will have good long term stability.

We also believe that the product will have good long term stability when applied to a surface preventing reinfection for many hours following application.
