Rideal-Walker coefficient
Encyclopedia
The Rideal-Walker coefficient is a figure expressing the disinfecting power of any substance and is obtained by dividing the figure indicating the degree of dilution of the disinfectant that kills a microorganism
in a given time by that indicating the degree of dilution of phenol that kills the organism in the same space of time under similar conditions. Although very similar to the phenol coefficient
, the Rideal-Walker coefficient determines the phenol coefficient
utilizing the method (test) developed by English chemists Samuel Rideal, (1863–1929) and J.T. Ainslie Walker, (1868–1930).
Microorganism
A microorganism or microbe is a microscopic organism that comprises either a single cell , cell clusters, or no cell at all...

Phenol coefficient
Phenol coefficient is a measure of the bactericidal activity of a chemical compound in relation to phenol. When listed numerically, the figure expressing the disinfecting power of a substance by relating it to the disinfecting power of phenol may be a function of the standardized test performed. ...
