摘要：

The present invention has an object to provide coenzyme Q-containing particles, which can be easily and simply dispersed into water without any surfactants or other additives, and their production method. The present invention makes it easier to prepare an aqueous dispersion containing coenzyme Q, which is hard to disperse in water, as fine particles by modifying coenzyme Qinto a coenzyme Q-containing fine particle comprising coenzyme Qcovered with a biocompatible polymer. Therefore, compositions containing dispersed coenzyme Qin water, such as drinkable preparations, lotions, etc., can be produced in easy and simple manners.
