acumedia® Letheen Broth Base, Modified

• Intended Use: Letheen Broth Base, Modified is used with Polysorbate 80 for the recovery of microorganisms from cosmetics.
• Product Summary and Explanation: In 1948, Weber and Black described the value of a highly nutritional solid medium containing neutralizing agents for quaternary ammonium compounds in sanitizers. The addition of Lecithin and Polysorbate 80 to Tryptone Glucose Extract (TGE) Agar resulted in a medium that effectively neutralizes quaternary ammonium compounds in testing of germicidal activity. Total neutralization of disinfectants is critical. Disinfectant residues can result in a false negative (no-growth) test.
Letheen Broth Base, Modified is based on the formula described in FDA Bacteriological Analytical Manual, and a modification of Letheen Broth Base. Letheen Broth Base, Modified is recommended by the FDA for use in the microbiological testing of cosmetics.
