WebFor example, quaternary ammonium compounds and phenol have a concentration exponent of 1 and 6, respectively; thus, halving the concentration of a quaternary ammonium compound requires doubling its disinfecting time, but halving the concentration of a phenol solution requires a 64-fold (i.e., 2 6) increase in its disinfecting time 365, 413, 420. WebPhenol coefficient definition, the number indicating the effectiveness of a disinfectant as a germicide relative to phenol, which is arbitrarily assigned the number 1: based on the time required to kill a given quantity of a specific type of bacteria.

WebLysol consists of a mixture of the three cresol isomers solubilized using a soap prepared from linseed oil and potassium hydroxide, to form a clear solution on dilution. Most vegetative pathogens, including mycobacteria, are killed in 15 minutes by 0.3—0.6% lysol. Lysol has a phenol coefficient of 2. Bacterial spores are very resistant.

WebPhenol coefficient. The Phenol coefficient, is now largely of historical interest, although the principles upon which it is based are still used. [1] It is a measure of the bactericidal activity of a chemical compound in relation to phenol. WebA dilution of Lysol at 1:150 does not produce growth after 10 minutes, while a dilution of phenol at 1:90 does not produce growth after 10 minutes. Lysol therefore has a 5 times higher phenol coefficient than phenol, meaning that it is 5 times more effective than phenol. Filter Paper Method
WebPhenol coefficient can be similar or different for different microorganism. It can be understood by the example of Lysol. Lysol shoes no growth at 10 minutes when used as 1:450 dilution, while phenol shows no growth at 10 minutes when used as 1:90 dilutions. …
