Phenol coefficient compares the agent to phenol under the same conditions.
See Fig 7.6 3. Standard preparations of test bacteria are added to tubes containing dilutions of the agent being tested - incubate and observe presence of absence of growth. Most effective agents prevent growth at the highest dilutions D. Qualities of good disinfectant 1. Fast acting, even in presence of organic material 2.
