Nonideality of Mixtures of Pure Nonionic Surfactants Both in Solution and at Silica/Water Interfaces

Micellization and phase separation in binary amphiphile mixtures

“…In addition, the different tail group types are evenly distributed throughout the micelle. The large cmc deviations from ideal mixing that are seen in some binary nonionic surfactant solutions are thought to be a result of demixing within an aggregate [48], so our observation is consistent with the cmc measurements suggesting that the mixture is ideal. The second type of mixture we studied contains R 7 (T 16 ) 2 and R 7 (T 8 ) 4 at T ¼ 11.0, both of which undergo a first-order phase transition between a low and high density liquid phase [45].…”

Mixtures of n-dodecyl-β-d-maltoside and hexaoxyethylene dodecyl ether — Surface properties, bulk properties, foam films, and foams

“…From a study of C 12 E 6 on oxidised silicon by neutron reflection, Penfold concluded that 'the exact nature and details of the surface treatment and its history will critically affect its adsorption properties'. Values reported for the limiting surface excess of C 12 E 6 on silica at neutral or ambient pH range from 0.5 to 5.4 µmol m − 2 [15,[25][26][27][28][29][30]. The situation with the adsorption of β-C 12 G 2 on silica is clearer: both published studies report weak adsorption with a maximum surface coverage of 0.2-1.0 µmol m − 2 [17,31].…”

Adsorption of mixtures of nonionic sugar-based surfactants with other surfactants at solid/liquid interfaces

“…Various interactions between solid substrates and cationic-nonionic or nonionic-nonionic surfactant systems have been reported [3][4][5][6][7][8].…”
