As the world adapts to the post-COVID era, disinfectants have become an irreplaceable part of life. Foam disinfectants are excellent but suffer from foam destabilization when mixed with high ethanol concentrations. To address this issue, researchers from Japan have added an anionic surfactant, a long-chain alcohol, and an inorganic electrolyte to aqueous solutions with high ethanol concentrations, demonstrating enhanced foam stability. Their strategy could enable the formulation of stable, foam-type hand sanitizers.
