†WT is the mass fraction of the total surfactant in solution; RLA is the mass fraction of LA to total surfactant composition (RLA = wLA/(wLA + wC12EO4)).
‡cT is the molar concentration of the total surfactant in the solution; RnSL is the mole ratio of SL to the surfactant mixture (RnSL = nSL/(nSL + nTTABr)).
