The micellization of two heteropolar surfactants, 2-(decyldimethylammonio) ethanol bromide and 2-(decyldimethylammonio) butanol bromide, in aqueous solutions has been detected by conductometry and light scattering. The latter technique was used to characterize the size, the mass, and hence the aggregation number of the micelles formed. The comparison between micelles formed from two amphiphile molecules containing differently ...
