Extended surfactant interaction
WebHowever, the surfactant interactions in these systems are also inherently of great theoretical interest. Interaction between dissimilar surfactants in various aggregation processes is being investigated. ... Surfactants normally have a hydrophobic alkane tail and a hydrophilic head; in extended surfactants a group that is less hydrophobic then ... WebFeb 26, 2011 · The concept of extended surfactants (Fig. 2) originated from the effort to increase the surfactant-oil interaction. Attempting to increase this interaction by increasing surfactant hydrocarbon chain length is limited to 18 or fewer carbons due to surfactant phase separation beyond that point.
