Abstract These behaviors reflect the dependence of the dispersion power on the presence of surfactant molecules in the soluble form rather than micelles [Adal et al. (1994)]. This can be attributed to the solubilization of crude oil into the hyDROPhobic interior core of micelle [Naylar (1986)]. A real improvement in the percentage of dispersed oil was observed for the blends when compared to the individual MPA-PEG600 performance. The interactions between components of dispersant 1 are favorable for interface stabilization and give a quite good dispersion test. Finally, The lowering of IFT and the improved stability of O/W emulsions combining surfactants with high and low HLB have been explained through some specific molecular association of surfactants at the interfaces [Takamura et al. (1979) and Tenhu et al. (1992/1993)]. |
