| description | Surfactant mixtures are very often used in various cosmetic and
pharmaceutical products because they commonly act in synergism and provide
more favorable properties than the single surfactants. At the same time, the
9 presence of polymers in mixtures of surfactants may lead to molecular
interactions thereby affecting product stability and activity. For these
reasons it is very important to determine the surfactant interactions
influence on 1micellization and mixed micellization, as well as
polymer-surfactants mixed micelles interactions. In this work we examined
self-aggregation of nonionic surfactants, polysorbate 20 (Tween 20),
polyoxyethylene octylphenyl ether (Triton X100) and
polyoxyethylene-polyoxypropylene block copolymer (Pluronic F68) with ionic
surfactant, sodium dodecylsulfate, in aqueous solution at 40ºC using
conductometric titration method. It was found that concentration region for
mixed micelle formation depends on nonionic surfactant characteristics and
its concentration. Formation of surfactants mixed micelles in the presence of
nonionic polymer, hydroxypropylmethyl cellulose, and their binding to polymer
hydrophobic sites, were investigated too. Analysis of obtained results points
to different kinds of interactions in investigated systems, which are crucial
for their application. [Projekat Ministarstva nauke Republike Srbije, br. III
