Letheen agar w/ Triton X-100 is recommended for screening cosmetic products for microbial contamination. It supports luxuriant growth of most organisms including detection of yeast and molds. Triton X-100 acts as a surfactant. Lecithin and polysorbate 80 to the medium enables the recovery of bacteria from materials containing residues of disinfectant compounds or preservatives used in cosmetics. Cosmetics contain preservatives hence they should be at least partially inactivated during the plating and this medium helps in dilution as well as neutralizing. Enrichment in this medium should be done for 7 days at 30-32°C and then subcultured on Letheen Agar, Modified (M946) and/or MacConkey agar (M081). Application: For Laboratory Chemicals, Analytical Purpose, Biochemical Analysis Appearance: Cream to yellow homogeneous free flowing powder Gelling: Firm, comparable with 1.5% Agar gel Color and Clarity of prepared medium: Yellow colored, clear to slightly opalescent gel forms in Petri plates Cultural ResponseM1642: Cultural characteristics observed after an incubation at 35-37°C for 18-48 hours
