The micellization behavior of bile salts—sodium cholate and sodium deoxycholate was studied in aqueous methanol, ethanol and ethylene glycol mixtures (10–20 % v/v) over a temperature range (300–320 K) by surface tension and conductivity methods. Critical micelle concentration, extent of counter ion binding (α), interfacial property ( A min , ζ max , π‐CMC, G ad ∘ ) and thermodynamic parameters ( G m ∘ , H m ∘ , S m ∘ ) for the micellization process are reported and discussed.
