1H NMR Study of a U-Type Nonionic Microemulsion

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

“…The O/W interface is less capable of accommodating the clxb molecules and its total solubilization load decreases dramatically. Confirmation of the existence of these three areas of microstructures in empty systems and in systems into which nutraceuticals were solubilized was obtained from SAXS and SD-NMR results that have been published elsewhere [21,[25][26][27][28]34,36,37].…”

Structural Polymorphism in a Four-Component Nonionic Microemulsion

“…50 wt% water (W 0 Å 74.8). It is noteworthy that for lines W5 and W6 no exceptional change in conductivity is observed near 60 wt% water (W 0 Å 89.7 for W5), where we could demonstrate for W5 and infer for W6 the occurrence of an inversion to O/W microemulsion (37,48). C 0 , the conductivity of the brine used ( 0.004 M NaCl) is 479 mS / cm.…”

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

“…However, as C 12 (EO) 8 is highly purified, it can hardly be commercially viable for full-scale applications. It would thus be more suitable for microstructure studies [27,[34][35][36]. For solubilization experiments, we preferred the second-best surfactant, C 18:1 (EO) 10 should be noted that the water solubilization achieved with the balanced surfactants of type C 18:1 (EO) j benefits from the presence of the double bond in the surfactant alkyl chain, as was discussed in our previous article [6].…”

“…The construction of pseudo-ternary phase diagrams for the systems studied was conducted by titration of selected combinations of surfactant, cosurfactant, and oil (cosurfactant/oil weight ratio was usually fixed at 1:1) with water at 27 ± 0.2 • C. The entire procedure is described elsewhere [6,12,13,[26][27][28].…”
