The true cost of a disinfectant can only be determined by taking into consideration the phenol coefficient and the cost of the disinfectant per gallon. The cost of a disinfectant per 100 units of efficiency as compared with pure phenol is obtained by first dividing the cost per gallon of the disinfectant by the cost per gallon of pure phenol; the efficiency ratio...
