Description: Biguanide group. It is a divalent cation. A clinically relevant biocide used as antiseptic, preservative, detergent, disinfectant. It is one of the more widely used disinfectants. It is used mainly in 3 salt forms such as Digluconate 20% solution, Diacetate and Dihydrochlorhide. A 4% emulsion of chlorhexidine gluconate is used as a skin cleanser, a 0.5% (w/v) solution in 70% isopropanol as a general antiseptic, and a 0.5% solution in 70% isopropanol with emollients as a hand rinse.

It has potent antimicrobial activity against most gram-positive and some gram-negative bacteria but not against spores. A 0.1% aqueous solution is bactericidal against Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa in 15 sec. However, it is relatively ineffective against other gram-negative organisms, spores, fungi, and most viruses.
