Contribution to the study of the combined effects of aqueous solution containing surfactants and biopolymers on some physical and rheological parameters

Abstract

The study of interactions between micellar systems in the presence of additives (polymer electrolyte) has attracted great scientific interest because of the many practical applications in the food, pharmaceutical, cosmetic, and petroleum industries, especially in enhanced oil recovery. In the latter case, the oil droplets are trapped in porous media and can be moved only under the combined effect of viscous and interfacial forces. This is an aim that can only be achieved with mixed polymer/surfactant systems mixed with other additives. Moreover, in other industries, the formulation of stable emulsions tends increasingly to the use of polymers having significant surface properties alone or mixed with surfactants that provide a medium viscosity and stability to the system. This work is a contribution to the study of the interactions and the effect of these latest on the physicochemical and rheological properties of systems containing soluble biopolymers: Arabic gum, cetomacrogol 1000 and starch, an anionic surfactant, sodium dodecylbenzene sulfonate (LABSNa), and olive oil.
