Surface-Active Quaternary Ammonium Germicides accumulates in the pages of one volume a review of the history, chemistry, biology, and application of the quaternary ammonium salts that have appeared in print to date. The quaternary ammonium surface-active antiseptics have secured a prominent and important place in the fields of medicinal and general disinfection during the past decade. These compounds are of particular interest in that, unlike most other disinfectants, they exhibit not only germicidal action but also surface-active, detergent, and wetting properties.
