Investigation to Increase the Viricidal Capacity of Disinfectant, Germicidal and Fungicidal, Phenolic, Dry-Type
Abstract
The straight O-D-1435 Type II disinfectant had little capacity to inactivate the poliovirus type I when used in concentrations up to 15,000 mg/l with contact times up to 24 hours. The Coxsackie A9 and Echo 12 viruses showed no inactivation with 10,000 mg/l of disinfectant and contact times of 30 minutes. An increase of the pH to more than 12 did potentiate the disinfectant for poliovirus inactivation. The survival at a pH of 12.1 with 10,000 mg/l of disinfectant was less than 0.01 percent after 5 minutes of contact. The survival at this pH without the disinfectant was 58%. Anionic surfactants in concentrations from 100 to 10,000 mg/1 had little capacity for increasing the viricidal capacity of the disinfectant. Cationic and nonionic surfactants had no enhancement ability.
