Microstructure of alkyl glucoside microemulsions: Control of curvature by interfacial composition
(2003) In Langmuir 19(26). p.10692-10702- Abstract
- The phase behavior of water/n-octane/n-octyl-beta-D-glucopyranoside (C(8)G(1))/1-octanol (C8E0) permits formulating temperature-insensitive microemulsions spanning the whole water-oil composition range. The types of microstructures formed along the trajectory of the middle-phase microemulsion are examined by NMR diffusometry, yielding the respective diffusion coefficients of all the components. The diffusion experiments provide clear evidence of the transition from oil-in-water to water-in-oil microemulsions via bicontinuous structures in a remarkably large range around phase inversion. Small-angle neutron scattering (SANS) along the same path confirm the picture. Furthermore, SANS curves on the absolute scale permit extracting the... (More)

When the composition of the internal interface is known, the mean area per surfactant molecule is determined. It is found that as the interfacial film becomes increasingly ri
h in C8E0, that is, the phase inversion is passed, the mean area per surfactant molecule C(8)G(1) decreases along the same progression. (Less)
