Volume behavior of mixed micelles of dodecyltrimethylammonium chloride and bromide [PDF]
Journal of Solution Chemistry, 1991 Densities of aqueous solutions of mixtures of dodecyltrimethylammonium chloride (DTAC) and dodecyltrimethylammonium bromide (DTAB) have been measured as a function of total molality at constant composition and the apparent molar volumes of the mixtures were derived from the density data.

Lubrication in aqueous solutions using cationic surfactants ? a study of static and dynamic forces
, 2002 This paper concerns lubrication in aqueous surfactant systems where the surfactants adsorb at surfaces, in relative motion, forming either a surfactant monolayer or a multi- (liquid crystalline) layer.

Mix-and-Match Diols: Adjusting Self-Assembly of Micellar Phases in Choline Chloride Eutectics
Crystals, 2022 The common Deep Eutectic Solvent (DES) ‘ethaline’ (1:2 choline chloride:ethylene glycol) was examined here as a basis for the self-assembly of the surfactant dodecyltrimethylammonium bromide (C12TAB). A phase diagram was constructed, showing evidence for

Probing competitive interactions in quaternary formulations [PDF]
, 2015 Hypothesis The interaction of amphiphilic block copolymers of the poly(ethylene oxide)–poly(propylene oxide)–poly(ethylene oxide) (PEO–PPO–PEO) group with small molecule surfactants may be “tuned” by the presence of selected alcohols, with strong ...
