Growth rates of ibuprofen crystals grown from ethanol and aqueous ethanol

► Ibuprofen crystal growth rates in ethanol and aqueous ethanol measured. ► Growth kinetics are first order. ► Growth rate coefficient varies with temperature with an activation energy of 13.7 kJ/mol. ► With aqueous ethanol the growth rate coefficient varies log-linearly with water content depending on the temperature. ► Material exhibits growth rate dispersion (GRD).
