Intended Use
Letheen Broth Base, Modified is specifically designed for use with Polysorbate 80, facilitating the recovery of microorganisms from cosmetic products.
Product Summary and Explanation
Originally described by Weber and Black in 1948, Letheen Broth Base has proven to be invaluable in microbiological testing. This highly nutritional medium contains neutralizing agents that effectively counteract the impact of quaternary ammonium compounds found in various sanitizers. By incorporating Lecithin and Polysorbate 80 into Tryptone Glucose Extract (TGE) Agar, this product creates an optimal environment for the total neutralization of disinfectants. This is essential in achieving accurate test results; residues from disinfectants can lead to false negatives (no-growth results).
Based on the formulation outlined in the FDA Bacteriological Analytical Manual, Letheen Broth Base, Modified is a refined alternative of the original Letheen Broth Base. It comes highly recommended by the FDA for microbiological testing of cosmetics, ensuring compliance with safety and efficacy standards.
