The effect of structural variation of alcohols on water solubilization in nonionic microemulsions

Microstructure and structural transition in microemulsions stabilized by aldonamide-type surfactants

“…They did not acquire significant influence of the isomery of cosurfactant (n-propanol vs iso-propanol) on the microemulsion area. In some cases, however, the phase behavior of a sugar surfactant was found to be influenced by the cosurfactant branching [45,46]. Nevertheless, it is clear that iso-butanol is the optimal alcohol as a cosolvent in a N -alkyl-N -methylgluconamide/ cosurfactant/iso-octane/water system.…”

Improved solubilization of Celecoxib in U-type nonionic microemulsions and their structural transitions with progressive aqueous dilution

“…The alcohol facilitates formation of multipurpose transformable systems [38][39][40]. In the water-poor region the alcohol migrates to the interface and competes with the drug on the free interfacial sites.…”

Fully dilutable microemulsions embedded with phospholipids and stabilized by short-chain organic acids and polyols

“…The interfacial properties of the surfactant or surfactant mixture is affected by several factors such as type of head group [38], type of tail group [39], number of tail groups [39], and length of tail groups [40][41][42][43]. Thus, changes in the composition of this surfactant/PG mixture will affect the phase behavior of the microemulsion systems.…”
