HYDROPHOBIGALLY ASSOCIATIVE POLYMERS AND THEIR CONTROL OF PROPERTIES OF SURFACTANT MESOPHASES AND LIPOSOMES

摘要

The control of complex fluid rheology, phase behavior, and stability is often of concern in cosmetics, Pharmaceuticals and personal care formulations. Water-soluble polymers with discrete hydrophobic anchoring sites offer significant flexibility in tuning the properties of these systems. The hydrophobic moiety can couple to the interior of surfactant micelles, lipid bilayers or oil phases while the hydrophilic regions of the chain provide entropic barriers that control distances between structures. We consider three systems: concentrated surfactant lamellar phases, rod-like micelle phases, and liposomes,.
