水性泡沫在我们日常生活中使用的许多商业产品中都会遇到，并被广泛研究。然而，使用高醇含量（>75%）溶剂如乙醇形成和稳定泡沫仍然是一个科学挑战。在此，我们首次报道了基于高乙醇含量的泡沫，通过使用天然脂肪酸晶体显示出长期稳定性。片状晶体被吸附在空气-水表面，保护气泡免于聚结。晶体的熔化触发泡沫的去稳定化，导致热刺激的高乙醇含量泡沫。这些泡沫可用作酒精基洗手液的新配方策略，以更好地清洁双手，通过脂肪酸的存在保护皮肤，并限制病毒和其他病原体的传播。
Aqueous foams are encountered in many commercial products used in our everyday lives and are widely studied. However, the formation and stabilization of foams using high alcohol content (>75%) solvents such as ethanol is still a scientific challenge. Herein, we report for the first-time foams based on high ethanol content showing long-term stability by using natural fatty acid crystals. The platelet-shape crystals are adsorbed at the air-water surface protecting the bubbles against coalescence. The melting of crystals triggers the foam destabilization leading to thermostimulable high ethanol content foams. These foams can be used as a new formulation strategy for alcohol-based hand sanitizers to better clean hands, protect the skin by the presence of fatty acids, and limit the transmission of virus and other pathogens.
