Modified Letheen Broth intended for use in the isolation of microorganisms from cosmetics. Total neutralisation of disinfectants is critical as disinfectant residues can result in a false negative result. Sodium bi-sulphite, Lecithin and Polysorbate 80 (Tween 80) inactivate quaternary ammonium compounds. Tween 80 neutralises phenols, formalin, hexachlorophene and, in combination with the Lecithin, ethanol.
