Effect of sodium salicylate, sodium oxalate, and sodium chloride on the micellization and adsorption of sodium deoxycholate in aqueous solutions

► Salicylate and chloride have similar effects on sodium deoxycholate micellization. ► Oxalate ions affect differently sodium deoxycholate micellization. ► Effect of oxalate on counterion binding to deoxycholate micelles is quite different. ► No obvious role of salicylate on deoxycholate micellization on its choleretic effect.
