The relative arrangement and interaction of the cationic butane-1,4 bis(dodecyl dimethyl ammonium chloride) gemini (12–4–12) with nonionic sugar-based surfactant n-dodecyl-β-d-maltoside (DM) was studied by NMR techniques. It is shown that the methylene group next to the ammonium head in the gemini is close to the penultimate sugar ring of DM in their mixed micelles, and the hydrophobic chain of DM...
Microstructures of the micelles of cationic surfactants, dodecyltrimethyl ammonium chloride (DTAC), alkane-bis(dodecyl dimethyl ammonium chloride) (12-4-12 and 12-8-12 geminis) in aqueous solutions, as well as the mixed micelles of their mixtures respectively with nonionic sugar-based surfactant n-dodecyl-β-d-maltoside (DM) were studied using NMR by 1 H chemical shift, self-diffusion coefficient,...
Nuclear magnetic resonance (NMR) spectroscopy is a versatile technique at a molecular level for the study of surfactants. Mixed micellization of nonionic sugar-based surfactant n-dodecyl-β-d-maltoside (DM) and cationic surfactant octane-1,8 bis(dodecyl dimethyl ammonium chloride) gemini (12-8-12) was studied using NMR by self-diffusion coefficient, spin–spin and spin–lattice relaxation time, and two-dimensional...
