Abstract: Abstract Effect of the numbers of oxypropylene on dynamic interfacial tensions (IFT) of five extended surfactants C12-14PmE2S (m = 0, 3, 5, 8 and 12) were investigated. The effects of electrolyte (NaCl and CaCl2) concentration, salinity, surfactant… read more here.

Abstract: HYPOTHESIS The properties of conventional surfactants (c-surfactants) are generally accepted to be amphipathicity-dominated, but extended surfactants (e-surfactants) are additionally polypropylene oxide (PPO)-dependent; this additional property makes us wonder how an intramolecular PPO spacer would be… read more here.
