Descrição geral

Dodecyltrimethylammonium bromide is a single-chain surfactant.

Aplicação

Dodecyltrimethylammonium bromide has been used in a study to assess the relation between counterion distribution and miscibility of counterions at the solution surface. This was deduced for surfactant mixtures containing common surfactant ions but different counterions. It has also been used in a study to investigate its micelle formation throughout the entire composition range of water-dimethylsulfoxide (DMSO) mixtures using conductimetry, density measurements, and small angle neutron scattering.

Polyelectrolytes with amphiphilic counterions, PEACs, are water insoluble because the amphiphiles self-assemble into highly charged micelles that strongly associate with the equally highly charged polyions. However, in the presence of water soluble cyclodextrins (CDs) that form inclusion complexes with the
