Document Type and Number:
WIPO Patent Application WO/2002/090304
Kind Code:
A1
Abstract:
By maintaining reduced coenzyme Q, which has not been employed in practice so far because of being liable to undergo oxidation and hydrophobic, stable against oxidation, a composition of a practically usable solution of reduced coenzyme Q, a method of preparing the same and a method of storing the same are provided. A solution of reduced coenzyme Q which can be stored at a low temperature or room temperature over a long time can be prepared by coating reduced coenzyme Q with liposomes made of refined soybean lecithin, etc. and solubilizing, or solubilizing or emulsifying reduced coenzyme Q by using a surfactant at a low concentration.
