Solubility (Water 0.1%w/v) Coenzyme Q10	95.0% min	96.37%	Distilled water is used to prepare water soluble Coenzyme Q10 solution (10ml) whose concentration is 1mg/ml . The solution should be extracted by ultrasonic for 1 hour and be centrifugal for 10 minutes at the speed of 2000r/min. The content of clear solution should be measured.
Dispersity (Water 0.1%w/v)	No suspended materials and sediments	Complies	Distilled water is used to prepare water soluble Coenzyme Q10 solution (10ml) whose concentration is 1mg/ml . The solution should be placed for 30 minutes after 15 seconds vibration. Appearance should be observed. No suspended materials and sediments should be found.
