Product Usage:
Used as a surface-active fungicide, it has quite strong broad-spectrum bacteriostatic and bactericidal action, effective against gram-positive bacteria and Gram-negative bacteria. Antiseptic and antiseptic. Surface active dosage form fungicide.
Biological activity Chlorhexidine hydrochloride(NSC-185) is used as a preservative,Effective against most Gram-negative and positive organisms.Although it is less effective against some gram-negative bacteria, it is effective against both gram-positive and Gram-negative bacteria. It has both bactericidal and bacteriostatic mechanisms, and the mechanism of action is cell membrane interference rather than inactivation. It is also effective against fungi and enveloped viruses, although the effect is not widely studied.Chlorhexidine is harmful in high concentrations, but safe at low concentrations in many products, such as mouthwashes and contact lens treatments. Uses As a surface active fungicide, it has a very strong broad spectrum bacteriostatic and bactericidal effect, and is an effective antiseptic for Gram-positive and gram-negative bacteria. Uses surface active dosage form fungicide
