Principle :- Letheen agar modified is composed of peptone, meat extract (equivalent of beef extract), tryptone, yeast extract, sodium chloride, dextrose, polysorbate 80, lecithin, sodium bisulfite and agar. Peptone, Meat extract, yeast extract and tryptone provide nitrogenous and carbonaceous compounds, long chain amino acids, vitamins and trace elements for the growth of microorganisms. Sodium chloride maintains osmatic equilibrium. Dextrose is carbon source. The lecithin and polysorbate 80 aids the recovery of bacteria from materials containing residues of disinfectant or preservatives used in cosmetics. Polysorbate 80 and lecithin nullify phenolic compounds, hexachlorophene, and formalin and neutralizes ethyl alcohol. Lecithin also neutralizes quaternary ammonium compounds present in the cosmetics. Sodium bisulfite enhances growth of microorganisms and neutralizes the preservative.

Use :- Recommended for screening cosmetic products for microbial contamination and evaluating the bactericidal activity of quaternary ammonium compounds.
