PROBLEM TO BE SOLVED: To provide a kit for obtaining a foam-type external preparation for skin of constant quality regardless of quality of water to be used, in which agents are easily mixed uniformly in mixing, carbonic acid gas having blood circulation promoting effect is generated evenly in the mixing, and an extra work of measurement by a user is not required in the mixing.SOLUTION: There is provided a kit for obtaining a foam-type external preparation for skin in which a first agent is a composition containing an acid substance, a carbonic acid gas-generating substance that reacts with the acid substance to generate carbonic acid gas, and thickener, and a second agent contains water and/or moisturizing agent. It is preferable that the first agent is a solid composition, and the second agent is a liquid composition. It is preferable that an acid substance and a carbonic acid gas-generating substance, of the first agent coexist not to contact each other. It is preferable that the acid substance is citric acid and the carbonic acid gas-generating substance is sodium hydrogen carbonate. |
