WebbTo sum up, some researchers have found that the theoretical phenol coefficient of Dettol is 1 (Sharif, 2014), which means that Dettol is more effective than Phenol. Nevertheless, the results obtained in this laboratory with a PC of 5 shows that this detergent is less effective than the Phenol, the reasons for the possible failed were explained previously. WebbA disinfectant with a phenol coefficient of 1.0 has the same effectiveness as phenol (Dorland s Illustrated Medical Dictionar). A coefficient less than 1.0 means that the disinfectant is less effective than phenol and greater than 1.0 is more effective than phenol. Phenol coefficients are reported separately for the different test organisms.
