Micellar dispersion of α-monoglycerides in benzene and chlorobenzene

The Number-Average and Weight-Average Molecular Weight of Some Nonionic Surface-Active Agents

“…A c.n~.c. of 0.12 g/100 g solvent agrees well with the value 0.14 g/100 1111 obtained for the pure a-monostearin from light-scattering determinations by Debye and Prins (2). Considering that some impurities may be present in the coillinercial substailce it is difficult to ascribe too inuch significance to the c.m.c.…”

Quantitative Solubility Relationships and the Effect of Water Uptake in Triglyceride/Monoglyceride Microemulsions

“…Lipid mixtures containing monoglycerides such as the 1-monocaprylin/benzene mixture have been shown to possess a critical micelle concentration (CMC) at which reverse micelles of monocaprylin form (59)(60)(61)(62)(63)(64). However, these studies also showed that in chloroform no CMC exists because it is a very good solvent for 1-monocaprylin.…”

Aggregation response of triglyceride hydrolysis products in cyclohexane and triolein

“…Third, the presence of residual water and variations in water content in experiments make comparisons between different systems difficult as many reverse micellar systems exhibit considerable sensitivity to water 11,20,21 . Finally, impurities in especially nonionic surfactants can influence the system behaviour via introducing additional surface active components into the system 22 .…”

“…Experimentally, the self-assembly of monoglycerides in nonpolar media has been studied extensively 15,22,[25][26][27][28][29][30][31][32] in various hydrocarbon and triglyceride solvents but only a few works address aggregate formation of diglycerides and fatty acids 21,[33][34][35] . Vapor pressure osmometry, calorimetry, light scattering, and small angle X-ray scattering (SAXS) studies indicate that small to medium sized reverse micelles of monoglycerides form in a wide range of hydrocarbon solvents 15,22,[25][26][27][28][29] . The morphology of the aggregates can be controlled through temperature, solvent structure, and polar impurities 22,26,28,36 .…”

The morphology of the aggregates can be controlled through temperature, solvent structure, and polar impurities 22,26,28,36 . In vegetable oils, monoglycerides can form inverse lamellar structures [30][31][32] , which dissolve to form an isotropic fluid-like phase at a temperature dependent on the surfactant structure, concentration, and water content 30,31 .…”
