Reduced coenzyme q10-containing composition and the manufacturing method and the stabilizing method thereof

The present invention is a terpene in having a high solubility in oxidized coenzyme Q10 and reduced coenzyme Q10, when reducing oxidized coenzyme Q10 with a reducing agent, an alcohol, water, surfactant relates to a method for producing reduced coenzyme Q10, characterized in that the coexistence of at least one additive selected from the group consisting of active agents and diacylglycerol. The alcohols, water, surfactant and at least one selected from the group consisting of diacylglycerol compositions terpenes with a reducing agent containing reduced coenzyme Q10, furthermore, reduced coenzyme to the composition It relates to the stabilization method of enzyme Q10.
