Objective: Currently used alcohol-based hand sanitizers and surgical hand rubs are not effective against alcoholresistant microorganisms. We reported previously that nontoxic antioxidant food additive compounds derived from green tea polyphenols, particularly epigallocatechin-3-gallate-palmitate (EC16), are suitable for use in alcohol formulations to effectively inactivate nonenveloped viruses and bacterial spores. However, whether EC16 influences the bactericidal and fungicidal activity of alcohol is not clear. The objective of the current study was to determine the bactericidal and fungicidal activities of ProtecTeaV hand sanitizer and surface spray prototypes containing EC16. Methods: The prototypes were tested according to the guidelines from the Food and Drug Administration (FDA) and the Environmental Protection Agency (EPA). Results: As expected, EC16 did not reduce the bactericidal and fungicidal activities of ethanol. The hand sanitizer gel formulation was equally effective as 70% ethanol and met the tested standard, and the surface spray prototype met the EPA performance standard. Conclusions: EC16 can be combined with ethanol without reducing antibacterial or antifungal activity, and the ProtecTeaV prototypes could be further developed into novel hand hygiene and surface disinfectant products with virucidal, bactericidal, fungicidal and sporicidal activities.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
