Mesoscopic Simulation of Agglomeration Behavior of Laaurate Polyoxyethylene Ether and Sodium Dodecyl Sulfate(cas 151-21-3)

The interaction between lauryl alcohol polyoxyethylene ether (C12E10) and sodium dodecyl sulfate system(cas 151-21-3) was studied by MesoDyn density functional method. The microstructures of aggregates were simulated and the morphology of aggregates. The effects of shear on the phase behavior were studied, and the aggregation of the beads in the C12E10 /SDS complex system was discussed by means of two-dimensional density slices. On this basis, benzene and n-octanol were used as oil.

The results show that there is a strong synergistic effect between the nonionic surfactant C12E10 and the anionic surfactant sodium dodecyl sulfate system(cas 151-21-3), and when the concentration of C12E10 /SDS is very low, The effect of shear on the behavior of the system is explained to the extent that the difference between the real experiment and the simulation is explained. The observation of the density slice shows that the difference of the selected oil structure leads to the complex system The difference in the way of its solubilization.
