Dodecyltrimethy lammonium

Amiel et al. [85, 86] investigated the formation of ternary complexes of a water soluble epichlorohydrin-linked f-CD polymer, cationic surfactant dodecyltrimethy-lammonium bromide (DTAB), and a polyanion sodium salt dextran sulfate (NaDxS) by viscometry and small angle neutron scattering. They proposed a structure of polyion complexes between NaDxS and the supramolecular polycation formed from fi-CD polymer and DTAB. More recently, Amiel et al. [87] have characterized in detail the supramolecular polycation. 

X-ray scattering (SAXS) have yet been done. The interaction of L64 with three different cationic surfactants was investigated by Mahajan et al. using SANS [67]. These authors employed the surfactants hexadecyltrimethylammonium bromide (HDTAB), tetradecyltrimethylammonium bromide (TTAB), and dodecyltrimethy-lammonium bromide (DTAB). For all studied cationic surfactants and all ratios of L64 to surfactant, the authors report ellipsoidal micelles. Since this is the preferred shape of the micelles of the pure cationic surfactants, they conclude that in this case the shape is dominated by the surfactant [67].
