Abstract

The critical micelle concentrations (cmcs) of chlorhexidine digluconate (CG) in aqueous solution were determined over the temperature range 15-40°C by a method based on deconvolution into Gaussians of the second derivative of the conductivity/concentration data. The mass-action model was modified in order to calculate the thermodynamic parameters (ΔG_m⁰, ΔH_m⁰, ΔS_m⁰) of micelle formation. To verify the theoretical predictions the enthalpy of micelle formation at 25°C was calorimetrically determined.
