Interaction of cefalexin monohydrate with cetyldimethylethylammonium bromide

Conductivity and fluorescence studies on the micellization properties of sodium cholate and sodium deoxycholate in aqueous medium at different temperatures: Effect of selected amino acids

“…Therefore the results observed indicate that the contribution of the chemical part towards micellization or stability of the micelle formed is enhanced in the presence of amino acids and this effect is more pronounced with leucine and NaDC as well. Similar (enthalpy + entropy) compensation has also been observed in case of (SDS + amino acid) aqueous systems [50].…”

“…Further, both types of hydrations are known to decrease with increase in temperature [49]. However, a decrease in hydrophilic hydration favors the micellization while a decrease in hydrophobic hydration disfavours the micelle formation with rise in temperature [50,51]. Consequently, the dominance of these two factors will determine whether the CMC (or X CMC ) values increase or decrease over a particular temperature range.…”

Effect of temperature and salts on the interaction of cetyltrimethylammonium bromide with ceftriaxone sodium trihydrate drug

“…Table 1 gives details about the compounds used including the CAS numbers, molar mass, supplier and mass fraction purity. The measurement of the specific conductances of (CFT+CTAB) system was done using a 4510 conductivity meter (Jenway, UK) with a dip cell (glass electrode) of cell constant 0.97 cm -1 (the value is provided by manufacturer) and with alternating current (AC) voltage source at frequency of 60 Hz following the procedure reported in the literatures [4][5][6][7][11][12][13].…”

“…It can also be used to treat gonorrhea. Although a number of studies on the interaction of surfactants with different solute molecules including drugs are reported in the literature [3][4][5][6][7][8][9], to the best of our knowledge very little is known about the interaction of CFT with CTAB. In our previous papers, interaction of cephalosporin and beta lactum antibiotic drugs with ionic surfactants such as hexadecyltrimethylammonium bromide (HDTAB), dodecyltrimethylammonium bromide (DTAB), cetyldimethylethylammonium bromide (CDMEAB) and sodium dodecyl sulfate (SDS) in water and in aqueous solution of different salts were reported [4][5][6][7].…”

Micellization behavior of mixtures of amphiphilic promazine hydrochloride and cationic aniline hydrochloride in aqueous and electrolyte solutions

“…Both types of hydrations are known to reduce with increase in temperature [31]. Only hydrophilic dehydration favors the micelle formation at lower temperature, while with the increase in temperature; hydrophobic dehydration disfavors the micelle formation [32,33]. As a result, the magnitude of these two factors determines whether the CMC values increase/decrease at a particular temperature.…”
