​Across healthcare proper disinfection is imperative. Since the outbreak of the pandemic patients have also become more conscious about sterilisation and handwashing. It is therefore no surprise that researchers have been inspired to develop effective, easy-to-apply, disinfectants.

The media outlet EurekaAlert! explains, “Foam-type disinfectants are a leading candidate in this regard since they do not drip, keep the disinfected area visible, and are less likely to reach the user’s eyes.”

But foam disinfectants have their issues. Usually, foam disinfectants are stabilized with the absorption of a surfactant at the air/liquid interface, high ethanol concentrations and can be destabilized by foams in aqueous solutions.

Researchers from Tokyo University of Science (TUS) in partnership with Life Science Products Division, NOF Corporation, sought to solve these issues.

By adding an anionic (negatively charged) surfactant, long-chain alcohols, and an inorganic electrolyte to an aqueous solution containing a high concentration of ethanol (60 vol. per cent).
