The effect of Tan δ on frequency (Hz). (a) The Tan δ of the emulsions on frequency (Hz) for 10% oil phase concentration. Surfactant concentration; 5% (black-shaded square), 6% (red diamond), 7% (blue-shaded triangle), 8% (sky-blue-shaded triangle), 9% (brown decagon) and 10% (green diamond). (b) The Tan δ of the emulsions on frequency (Hz) for 20% oil phase concentration. Surfactant concentration; 5% (black-shaded square), 6% (red diamond), 7% (blue-shaded triangle), 8% (sky-blue-shaded triangle), 9% (brown decagon) and 10% (green diamond). (c) The Tan δ of the emulsions on frequency (Hz) for 30% oil phase concentration. Surfactant concentration; 5% (black-shaded square), 6% (red diamond), 7% (blue-shaded triangle), 8% (sky-blue-shaded triangle), 9% (brown decagon) and 10% (green diamond).
