| abstract |
The invention is directed to a composition for preparing a carbon dioxide preparation for external use characterized by comprising a substance that produces an acid when being hydrolyzed, a carbonate, a thickening agent and water as essential components, and a composition for preparing a carbon dioxide preparation for external use characterized by comprising the essential components, a gelling agent for forming a gel by a calcium ion, and a calcium salt that is insoluble or sparingly soluble in water. According to the invention, the carbon dioxide preparation for external use, which contains sufficient amount of carbon dioxide, from which the carbon dioxide is absorbed transdermally or transmucosally in a sustained manner, and which has a more potent cosmetic or medicinal effect, can be easily prepared. In addition, the composition for preparing a carbon dioxide preparation for external use with a low production cost can be provided. |
