PRODUCT INTRODUCTION
description
Chlorhexidine is a bisbiguanide compound with a structure consisting of two (p-chlorophenyl)guanide units linked by a hexamethylene bridge. Chlorhexidine is a disinfectant that is added to soaps, cosmetics, toothpaste, and similar products. Veterinarians use it as a topical disinfectant for animals’ wounds. It is active against Gram-positive and Gram–negative bacteria, but not viruses.
