Letheen Broth Modified is based on the formula described in FDA Bacteriological Analytical Manual, and is a modification of Letheen Broth Base. It is a highly nutritious liquid medium recommended for use in the microbiological testing of cosmetics. This medium is also recommended by ISO 21149, ISO 21150, ISO 18415, ISO 22718, ISO 22717 and ISO 18416 normatives for the enrichment of aerobic bacteria, yeast and molds in cosmetic products. Beef extract and casein peptone provide nitrogen, vitamins, minerals and amino acids essential for growth. Yeast extract is the source of vitamins, particularly of the B-group. Sodium chloride supplies essential electrolytes for transport and osmotic balance. Lecithin, polisorbate 80 and sodium bisulfite neutralize quaternary ammonium compounds and partially neutralize the preservative system commonly found in cosmetics. The medium is also used for microbiological samples from surfaces that have been treated with disinfectants.
