阳离子和阴离子表面活性剂与聚乙二醇醚的相互作用之间的主要差异已被发现从测量的表面张力，电导率，染料溶解，和介质的pH值的变化的影响。由于该实验背景，陈述了以下离子表面活性剂与聚乙二醇醚在水中的相互作用的假设。在水中，阳离子表面活性剂和聚乙二醇醚之间仅形成弱的可逆疏水键，随着疏水表面活性剂基团的疏水性和温度的降低而增加。与阳离子表面活性剂不同，阴离子表面活性剂与聚乙二醇醚的络合非常显著。在这里，除了疏水键，电力似乎是非常重要的。的相互作用可能是由于部分正电荷转移到醚氧基团，因此，增加的阴离子表面活性剂的亲水基团的吸引力。
A principal difference between the interaction of cationic and anionic surfactants with polyglycol ethers has been found from measurements of surface tension, conductivity, dye solubilization, and the effects of change in pH of the media. Due to this experimental background, the following hypothesis of interaction between ionic surfactants and polygylcol ethers in water is stated. In water, only weak reversible hydrophobic bonding between cationic surfactants and polyglycol ethers is formed, increasing with hydrophobic character of the hydrophobic surfactant group and a decrease in temperature. Unlike cationic surfactants, complexing of anionic surfactants with polyglycol ethers is very marked. Here, besides hydrophobic bonding, electrical forces seem to be very important. The interactions are probably due to a partially positive charge transfer to the ether oxygen group and, consequently, an increased attraction of the hydrophilic group of the anionic surfactant.
