Cooling agents are small organic molecules known to evoke a sensation of cold by interaction with the transient receptor. In the present study, we demonstrate experimentally that some cooling agents could behave as hydrotropes in aqueous solutions in the absence of surfactants, and also as co‐surfactants/co‐solvents in aqueous solutions in the presence of a surfactant forming an interfacial film. The hydrotropy and co‐surfactancy/co‐solvency effect depends strongly on the type of perfumery ingredient. The hydrotrope concentration, the concentration at which the water solubility of the perfumery compound is enhanced, is surprisingly low, in the mmol/L range.

某些常用冷却剂的助表面活性剂，助溶剂和水溶性质

冷却剂是已知的小有机分子，可通过与瞬态受体相互作用而引起冷感。在本研究中，我们通过实验证明了某些冷却剂在不存在表面活性剂的情况下在水溶液中可作为水溶助长剂，在存在形成界面膜的表面活性剂的情况下在水溶液中也可作为助表面活性剂/助溶剂。亲水性和助表面活性剂/助溶剂的作用在很大程度上取决于香料成分的类型。出众的水溶助长剂浓度，即提高香料化合物的水溶性的浓度，在mmol / L范围内令人惊讶地低。
