Vitamin C composition stabilized with cationic material, anionic material and caffeic acid derivative

The present invention relates to a composition containing vitamin C. The composition according to the present invention includes cationic material and anionic material as a primary stabilizing agent of the vitamin C; and a caffeic acid derivative as a secondary stabilizing agent of the vitamin C. The caffeic acid derivative is water-soluble and, preferably, a new caffiec acid derivative as denoted by the chemical formula 1 below is used. According to the present invention, the cationic material and the anionic material generate an electrical double layer to stabilize the vitamin C primarily; water-soluble caffeic acid derivative stabilizes the vitamin C secondarily. Accordingly, the vitamin C is stabilized double so that the vitamin C is protected from being oxidized by air, heat and moisture.
