The Structure of the Mixed Nonionic Surfactant Monolayer of Monododecyl Triethylene Glycol and Monododecyl Octaethylene Glycol at the Air–Water Interface

Adsorption of Nonionic Mixtures at the Air–Water Interface: Effects of Temperature and Electrolyte

“…We have previously measured the surface composition for the C 12 EO 3 /C 12 EO 8 nonionic surfactant mixture as a function of concentration for two different solution compositions (3,4), equimolar and a 30 mol% C 12 EO 3 /70 mol% C 12 EO 8 mixture; these results are reproduced in Table 4 and Fig. 2.…”

“…The adsorbed amounts were determined using Eqs. [4] and [5]. The temperature of the solution was controlled to ±1…”

“…Extending some earlier reported results on the adsorption of the C 12 EO 3 /C 12 EO 8 mixture at the air-water interface (3,4), we have also investigated the effect of temperature and electrolyte on the surface composition of the same nonionic surfactant mixtures. We have previously reported some preliminary results on the effects on temperature on the adsorption of nonionic surfactants and nonionic surfactant mixtures (5).…”

Comparison of the Coadsorption of Benzyl Alcohol and Phenyl Ethanol with the Cationic Surfactant, Hexadecyl Trimethyl Ammonium Bromide, at the Air–Water Interface

“…This approach has been used extensively by us to determine the structure of surfactant monolayers (21) and mixed monolayers (7,22) to a resolution ∼1-2Å.…”

Computer simulation studies of surfactant monolayer mixtures at the water/oil interface: charge distribution effects

“…However, most commercial products consist of mixtures of surfactants, which have richer properties than individual surfactants. Therefore, surfactant mixtures have also been investigated using several experimental techniques such as calorimetry, X-ray, neutron scattering, and surface tension measurements, among others [10][11][12][13][14][15][16][17][18][19][20][21][22]. Moreover, mixtures of anionic-anionic, cationic-cationic, and nonionic-nonionic surfactants and combinations of those molecules have been also treated from the theoretical point of view [23,24].…”
