Abstract
A novel bis-biguanide compound suitable for use as a disinfectant has the following formula: ##STR1## where n is an integer from 2 to 10 inclusive. A pharmaceutically acceptable salt, particularly gluconate salt of the compound is also useful as a disinfectant. The bis-biguanide compound has germicidal activities comparable to those of widely used chlorhexidine with respect to width of antibacterial spectrum and is superior to chlorhexidine in immediate effectiveness. It exhibits excellent germicidal activities against Pyocyaneus bacilli, on which chlorhexidine has poor effect.
