PROBLEM TO BE SOLVED: To provide preparation compositions that enable preparation in a short time and easily, does not soil clothes, and enable preparation of a carbon dioxide external preparation that can give a stronger cosmetic and medical effect in a short time.SOLUTION: A composition for preparing carbon dioxide external preparations contains a water soluble acid, a thickener, and a water-soluble dispersant, as essential ingredients； contains a granulate in which the thickener is mixed with the water soluble acid and the water-soluble dispersant, carbonate, and water as well as a specific thickener, as an essential ingredients； and consists of a viscous composition that is mixed with a granulate when using. A composition for preparing the carbon dioxide external preparations consists of one or more water-soluble dispersants selected from lactose, sucrose, D-mannitol, fructose, or urea, and one or more carbonates selected from ammonium carbonate, ammonium bicarbonate, potassium carbonate, potassium bicarbonate, sodium carbonate, sodium bicarbonate, sesquisodium bicarbonate, and the like.SELECTED DRAWING: None【課題】調製が短時間で容易に行え、衣服等を汚すことがなく、より強い美容及び医療効果が短期間で得られる二酸化炭素外用剤を調製できる調製用組成物の提供。【解決手段】水溶性酸、増粘剤及び水溶性分散剤を必須成分とし、増粘剤が水溶性酸及び水溶性分散剤と混合されている粒状物と、炭酸塩、水及び特定の増粘剤を必須成分とし、使用時に粒状物と混合する粘性組成物とからなる二酸化炭素外用剤調製用組成物。水溶性分散剤として、乳糖、白糖、Ｄ－マンニトール、果糖又は尿素から選択される一種以上であり、炭酸塩として炭酸アンモニウム、炭酸水素アンモニウム、炭酸カリウム、炭酸水素カリウム、炭酸ナトリウム、炭酸水素ナトリウム、セスキ炭酸水素ナトリウム等から選ばれる炭酸塩等から選ばれる１種以上の炭酸塩からなる二酸化炭素外用剤調製用組成物。【選択図】なし
