Fluidity of the interfacial region

Role of the Fluidity of the Interfacial Region in Water-in-Oil Microemulsions... [Pg.75]

The behavior of water in oil microemulsions has been studied using different techniques light scattering, electrical conductivity, viscosity, transient electrical birefringence, ultrasonic absorption. All these experiments lead us to propose a picture of the microemulsions structure which assignes an important role to the fluidity of the interfacial region. [Pg.75]

The preceding analysis assigns an important role to the interaction between droplets or equivalently the fluidity of the interfacial region in the microemulsions structure. [Pg.84]

The cosurfactant molecules are polar enough to be surface active and reside between the tails of the surfactants, thereby increasing the buUdness of the tail group region. Cosurfactants have widely different hydrocarbon moiety sizes compared with the surfactants. Typical examples of cosurfactants are medium-chain alcohols, acids, and amines. The role of a cosurfactant is to (1) lower the interfacial tension down to a very small (near zero) value and increase the fluidity, (2) adjust the hydrophile-lipophile balance (HLB) and spontaneous curvature of the interface by controlling surfactant partitioning, (3) destroy the liquid crystalline and/or gel structures, and (4)... [Pg.409]
