Tryptic Soy Broth (TSB) with Lecithin and Polysorbate 20(Tween®20) is a complex medium designed for the enumeration of total microbial count present in the test sample. Lecithin along with Polysorbate 80 is effective against quaternary ammonium compounds, amphoteric surfactants, benzamidines, chlorhexidines, and dequadin. Polysorbate 80 inactivates benzyl alcohol, carbanilides, di-chlorobenzyl alcohols, benzoic acid, p-hydroxybenzoic acid and its esters, phenols, phenylethyl alcohols, and Solbrol (PHB esters). Upon incubation, the enumerated microflora can be plated, isolated, and identified.
