Description
The hydroalcoholic solution containing 2% Chlorhexidine and 70% Ethanol is highly stable and demonstrates high antimicrobial efficacy.
This antiseptic is indicated for intermediate-level disinfection of surgical instruments and a wide range of medical devices through manual application within a short contact time. The product is intended for direct use, WITHOUT dilution and WITHOUT rinsing. It has been dermatologically tested, demonstrating 0 (zero) irritation.
Hydroalcoholic solutions of Chlorhexidine Digluconate exhibit bactericidal, fungicidal, and virucidal activity. Chlorhexidine remains stable at room temperature and within a pH range of 5 to 7. Extensive international literature supports that dermal absorption of chlorhexidine is minimal and that it provides a rapid onset of antimicrobial action. The presence of organic matter does not significantly impair its antimicrobial efficacy.
The antimicrobial mechanism involves disruption of microbial cell membranes and walls, leading to cell lysis. In addition, 70% ethyl alcohol enhances membrane disruption, resulting in a synergistic antimicrobial effect between chlorhexidine and ethanol.
Key advantages include rapid germicidal action and a prolonged residual effect, forming a persistent antimicrobial barrier (“chemical glove”) lasting approximately 5 to 6 hours.
In hydroalcoholic formulation, efficacy is enhanced against clinically relevant Gram-negative bacteria and, in particular, Gram-positive bacteria. The product is effective against both enveloped and non-enveloped viruses, including SARS-CoV-2 and viruses such as respiratory syncytial virus (RSV), influenza virus, human immunodeficiency virus (HIV), herpes simplex virus (HSV), and cytomegalovirus (CMV).
Chlorhexidine 2% is active against fungi, yeasts, and mycobacteria, achieving a biocidal reduction of 99.99% within 5 minutes of contact against Staphylococcus aureus, Salmonella choleraesuis, Escherichia coli, Pseudomonas aeruginosa, Trichophyton mentagrophytes, Mycobacterium smegmatis, and Candida albicans, according to studies conducted using internationally recognized methodologies.
