We have studied the thermotropic and lyotropic phase behaviour of different monoalkyl glycosides using polarizing microscopy, differential scanning calorimetry and rheology. The dependence of the liquid crystal transition temperature and mesophase fo

Carbohydrate surfactants, such as n-alkyl β-D-glucopyranosides (CMG1) or 1-desoxy-1-N-methyldecanamido-D-sorbite (mega10), are nearly insoluble in n-alkanes and ternary mixtures of surfactant–water–n-alkane produce emulsions. On adding a cosurfa

The surface tensions of aqueous solutions containing sodium octylbenzenesulfonate were measured by means of a processor tensiometer at 20°, 25°, 30° and 35°C. A test for the layer model and thickness of the adsorbed phase is proposed. By means of
