CASE STUDY

Evaluation of Antibacterial and Antifungal Effectiveness in Hand Sanitisers

Hand hygiene is an essential component of infection control and plays a crucial role in preventing the transmission of microorganisms. Proper hand hygiene practices, including the use of hand sanitizers, can significantly reduce the spread of infections and diseases.

This study aimed to investigate the effectiveness of different concentrations of active ingredients in hand sanitizers, isopropyl alcohol (IPA) and benzalkonium chloride (BKC), against various bacterial species and fungi.

Qualitative analysis was conducted by observing the macroscopic growth of these microorganisms after exposure to different concentrations of IPA and BKC. The results indicated that most of the tested microorganisms were effectively disinfected at the optimal antimicrobial concentration ranges of both IPA (60%-90%) and BKC (0.1%-0.14%) present in hand sanitizers.

However, the study also revealed reduced susceptibility of E. faecium to BKC at concentrations of 0.1% and 0.05%. Therefore highlights the importance of using an effective antimicrobial concentration of the active ingredient in hand sanitizers for maximum effectiveness against microbial contamination.
