bibechana-13887	Bhattarai, Ajaya; Pathak, Kavita; Dev, Bikash	Micellization behavior of mixed surfactants in pure water and methanol-water mixed solvent media by density methods	2015	7	.pdf	application/pdf	2744	136	54	While here, in our case new improvement has been done by measuring density in both higher and lower concentration range of mixed surfactants and the cmc has been calculated (fig 2) and the cmcs are found to be increased for both the anionic-rich and cationic-rich mixtures by the addition of methanol in pure water. It is evident that density exhibits almost increase with increasing concentration of anionic-rich (SDS-DTAB) and cationic-rich (DTAB-SDS) solutions as shown in Figs 1A and 1B. In fact, the variation of density with mixed surfactant concentrations is always found to be linear in higher concentration range and such trend was also observed previously [9] whereas in the lower concentration range, a break can be seen with the decreasing pattern in densities.	cache/bibechana-13887.pdf	txt/bibechana-13887.txt
