Aqueous solution properties of nonionic n-dodecyl β-D-maltoside micelles

Abstract

Several properties of aqueous solutions of n-dodecyl β-D-maltoside (DM) have been investigated. Phase diagrams of DM and n-dodecyl β-D-cellobioside (DC) were constructed, and both showed extensive isotropic aqueous solution domains. As well, solutions of DM were studied by a fluorescence quenching technique, viscosity measurements, and a lipoidal pH indicator method to examine micelle size, intermicelle interactions and the micellar intefacial microenvironment, respectively. In addition, mixtures of DM with octakis(ethylene glycol) mono-n-dodecyl ether (C12E8) and several other additives were examined in order to ascertain their effect on the solution properties. As with earlier results the ..
