Extended surfactant interaction
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. WebThis method using two compensating effects produced by a bi-dimensional variation has been carried out in the past 40 years with all variables susceptible to alter the surfactant interactions with oil and water, i.e., salinity, ACN, temperature, pressure, surfactant head, surfactant tail, surfactant intermediate for extended type, co-surfactant ...
