Neogen® Letheen Broth with Tween
产品图片
Letheen Broth is primarily used for assessing the bactericidal activity of quaternary ammonium compounds, and is not intended for use in the diagnosis of disease or other conditions in humans.
Letheen Broth is used to determine the phenol co-efficient of cationic surfactants as recommended by the Official Methods of Analysis of the Association of Official Analytical Chemists (AOAC). It is also used in hygiene swabbing protocols where it is necessary to neutralize quaternary ammonium compounds.
A modification of FDA Broth, Letheen Broth contains lecithin to neutralize quaternary ammonium compounds and Polysorbate 80 to neutralize phenols, hexachlorophene, formalin and (with lecithin) ethanol.
Letheen Broth is easily prepared and has a clear appearance aiding in visual inspection for growth.
The American Society for Testing Materials (ASTM) specifies the use of Letheen Broth in the Standard Test Method for Preservatives in Water Containing Cosmetics.
