ASSOCIATION PHENOMENON OF ESTERS IN WATER/SURFACTANT/CO-SURFACTANT/HYDROCARBON SYSTEM [PDF]

Journal of Dispersion Science and Technology, 1996
The pseudoternary phase diagrams of water/sodium dodecyl suphate(SDS) :hexan-1-ol(35 :65)/hydrocarbon/esters were prepared. The esters used are ethyl-n-butyrate, ethyl benzoate, methyl oleate and methyl linolenate. While the hydrocarbons are n-decane and p-xylene.

Phase-field modeling droplet dynamics with soluble surfactants [PDF]

, 2010
Using lattice Boltzmann approach, a phase-field model is proposed for simulating droplet motion with soluble surfactants. The model can recover the Langmuir and Frumkin adsorption isotherms in equilibrium.

Micellization of Fluorocarbon and Hydrocarbon Surfactant Mixtures

Journal of Japan Oil Chemists' Society, 1992
Micellization of fluorocarbon and hydrocarbon surfactant mixtures in aqueous solution is reviewed. Simple fluorocarbon surfactant micelles can be characterized by growth from sphere to rod-and disk-like form, which is explained by packing constraint.
