The effect of cephanone on the first critical micelle concentration (cmc1) and the second critical micelle concentration (cmc2) of CTAB have been studied by methods of conductivity and fluorescence polarization. The aggregation number of CTAB micelles and the distribution coefficient of cephanone between the CTAB micelle and the aqueous phase have been studied through the methods of the static fluorescence and UV spectra, respectively. The results show that with increasing cephanone concentration, cmc1 and cmc2 of CTAB micelle both increase, whereas the aggregation number of micelles and the viscosity of CTAB micelle system both decrease. The results are related to the interaction between cephanone and CTAB and the distribution of cephanone between CTAB micelle and the aqueous phase.
