Cefixime trihydrate (CMT) has the usages to treat the bacterial infections of urinary tract, throat, ear &amp; tonsils. Herein, the current investigation describes the interaction of CMT with dodecyltrimethylammonium Bromide (DTAB) by means of the conductivity measurement method in H 2 O and aq. solutions of NaBr, Na 2 SO 4 , and Na 3 PO 4 . The experiments were carried out at 310.55 K for several concentrations of CMT/ salts and temperatures of 300.55−320.55 K for one particular concentration of CMT/ salts employed. In every case, a single critical micelle concentration ( CMC ) has been achieved. The addition of CMT augments the aggregation of DTAB. The  CMC  values of the DTAB + CMT mixture undergo a decrease in attendance of electrolytes in comparison to water medium. In the manifestation of electrolytes, the  CMC  values of DTAB + CMT mixed systems at 310.55 K and ionic strength of 1 mmol kg −1  follow the order: CMC (H 2 O + NaBr) &gt; CMC (H 2 O + Na 2 SO 4 ) &gt; CMC (H 2 O + Na 3 PO 4 ). The negative  ΔG ° m  values indicated that the micellization of DTAB + CMT mixture was spontaneous. The -Δ H ° m  and + ΔS ° m  values disclose that the assembly of DTAB + CMT mixture in aqueous medium is both enthalpy &amp; entropy-controlled process. The thermodynamics of transfer and enthalpy-entropy compensation have also been described in the ongoing study.
