Please help me. I want ways to kill germs by using disinfectants. Thanks in advance
The 'Phenol coefficient", is now largely of historical interest, although the principles upon which it is based are still used. It is a measure of the antimicrobial (disinfection) activity of a chemical compound in relation to phenol. When listed numerically, the figure expressing the power of a substance by relating it to the disinfecting power of phenol may be a function of the standardized test performed. For example, the Rideal–Walker method, introduced in 1903 gives a Rideal–Walker coefficient.
One way to compare disinfectants is to compare how well they do against a known disinfectant and rate them accordingly using the Phenol coefficient. The disinfectant to be tested is compared with phenol on a standard microbe (usually Salmonella typhi or Staphylococcus aureus). Disinfectants that are more effective than phenol have a coefficient greater than 1; those that are less effective have a coefficient less than 1.
