“…In the glucamide series, C 11 -GA, C 12 -GA, C 13 -GA, and C 14 -GA, a sharp decrease in CMC value is seen with increasing alkyl chain length. A similar effect of the hydrophobic group on CMC was also reported for alkyl glucosides (13). However, the effect of the hydrophilic group of the molecule appears to be of unexpectedly minor significance.…”

The surface properties [effectiveness of surface tension reduction (γ CMC ), critical micelle concentration (CMC), efficiency of surface tension reduction (pC 20 ), maximal surface excess concentration (Γ max ), minimal area/molecule at the interface (A min ), and the (CMC/C 20 ) ratio] of some well-purified N-alkanoyl-N-methyl glucamines and related polyol-based Nmethyl amide-type surfactants, having the structural formula RC(O)N(Me)CH 2 (CHOH) x CH 2 OH, where RC(O) = undecanoyl, lauroyl, tridecanoyl, myristoyl, and x = 1, 3, and 4, were investigated at 25°C in distilled water and 0.1 M NaCl. Water solubility of these compounds does not simply depend on the number of hydroxyl groups in the molecule but is associated with the balance between intermolecular hydrogen bonds and hydrogen bonds formed with water molecules. The fundamental interfacial properties, such as CMC and γ CMC , and two thermodynamic parameters, standard free energy of adsorption and standard free energy of micellization, were found to be significantly dependent on the hydrophobic acyl chain rather than on the number of CHOH groups in the hydrophilic moieties. By contrast, the practical performance properties were greatly dependent on the nature of the hydrophilic group. As a whole, these surfactants had desirable foaming properties and efficient wetting abilities. Furthermore, synergism in foaming and wetting abilities was observed in a binary mixture of these surfactants with an alkyloxyethylene sulfate.

“…However, the poor solubility of GLUACO8 does not allow the determination of the critical micellar concentration following the criteria of Vollhard and colleagues, as we have previously done with nonreducible monosaccharidic surfactants. 20 For disaccharidic compounds, a split of the capacity peak is observed at c \ 1 ] 10~3 M for MALTACO8 and c \ 5 ] 10~4 M for MALTACS8. As proposed by Nikitas et al,30,31 this splitting, which appears above the CMC, is related to the formation of multilayers of micelles on the electrode surface.…”

“…In particular we will compare their adsorption properties at a mercury electrode, determined by AC polarography (tensammetry), to those previously observed with non-electroactive glycosidic surfactants. 20 Experimental NMR spectra were recorded on a Bruker AC 400 spectrometer. Infrared spectra were obtained with a Nicolet Impact 400 FT spectrometer.…”

“…Adsorption of glycosidic surfactants at Hg electrode was studied by means of differential capacitance measurements (tensammetry) [172,173]. Monosaccharidic surfactants formed a hemimicelle monolayer, while for disaccharidic compounds, the formation of a micellar multilayer throughout the electrical double layer was suggested.…”
