100 W, 120 s	210.5±1.93	0.59±0.15	−29.6±1.94	Good transparence and dispersity
200 W, 120 s	203.8±2.37	0.37±0.09	−30.9±2.08	Good transparence and dispersity
300 W, 120 s	179.2±2.09	0.26±0.12	−32.1±3.07	Generation of bubbles during sonication
100 W, 240 s	181.9±1.72	0.31±0.07	−31.7±1.82	Good transparence and dispersity
