The adsorption of methanol, ethanol and propan-1-ol at the solution-air and solid-solution interfaces, their aggregation in the aqueous media as well as wetting properties regarding their applications as additives or co-surfactants in the surfactants aqueous solution were discussed based on the literature data. Mutual influence of alcohols and surfactants on the solution-air and solid-solution interface tension was considered. For this purpose there were used different methods allowing to describe or predict changes of water surface tension as a function of alcohols concentration. These, in turn, as a function of alcohol and/or surfactant concentration were also analyzed by means of the methods applied for prediction of surface tension of aqueous solution of the classical surfactants mixture. The same considerations related to the behaviour of alcohol and surfactant at the solid-solution and solution-air interfaces were made. To explain the behaviour of alcohols and surfactants mixture at the solution-air and solid-solution interfaces the components and parameters of water, alcohols, surfactants and solids surface tension as well as the Gibbs free energy changes during the adsorption process were taken into account. It was proved that wettability of some solids can be predicted based on alcohol and surfactants adsorption as well as surface tension components and parameters. As follows the mutual influence of alcohol and surfactant on their adsorption at the solution-air and solid-solution interfaces as well as on the wetting properties at the alcohol concentration from zero to its critical aggregation concentration (CAC) is different from that at its concentration higher than CAC.
基于文献数据，讨论了甲醇、乙醇和 1-丙醇在溶液-空气和固液界面的吸附、在水介质中的聚集以及作为添加剂或共表面活性剂在表面活性剂水溶液中的润湿性能。还考虑了醇和表面活性剂对溶液-空气和固液界面张力的相互影响。为此，使用了不同的方法来描述或预测水表面张力随醇浓度的变化。这些方法又可以通过用于预测经典表面活性剂混合物水溶液表面张力的方法进行分析。还对醇和表面活性剂在固液和溶液-空气界面上的行为进行了相同的考虑。为了解释醇和表面活性剂混合物在溶液-空气和固液界面上的行为，考虑了水、醇、表面活性剂和固体表面张力的组成和参数，以及吸附过程中的吉布斯自由能变化。证明可以根据醇和表面活性剂的吸附以及表面张力的组成和参数来预测某些固体的润湿性。因此，在零到临界聚集浓度（CAC）的醇浓度下，醇和表面活性剂在溶液-空气和固液界面上的吸附以及润湿性能的相互影响与高于 CAC 的浓度下的相互影响不同。
