PP1380 – D/E Neutralising Agar

Dey & Engley Agar has the ability to neutralise antimicrobial chemicals and is used for environmental sampling for the detection and enumeration of microorganisms present on the surface of sanitary importance. In this formulation the agar has been modified by the addition of Tween 80 (Polysorbate 80) and Lecithin. It is recommended for use in environmental testing, particularly in areas subjected to surface disinfection, and conforms to the requirements of the British Pharmacopeia for sterility testing of appropriate pharmaceutical products. Lecithin and Polysorbate 80 (Tween 80) inactivate surface disinfectants (Lecithin neutralises quaternary ammonium compounds and Tween 80 neutralises phenols, formalin, hexachlorophene and in combination with the Lecithin ethanol).
