Aqueous stock solution A and aqueous stock solutions H to O shown in Table 3 were prepared, and the obtained aqueous stock solution, liquefied gas, and carbon dioxide gas were filled in a pressure-resistant container with the formulation shown in Table 4 to produce a test aerosol product. Evaluation of said (1)-(5) was performed about the obtained aerosol product for a test. The evaluation results are shown in Table 4. In Table 4, the content of each aqueous undiluted solution and liquefied gas is expressed in parts by mass, and the content of carbon dioxide gas is expressed as the equilibrium pressure in the pressure vessel after filling.

Formulation Example 1 Facial Wash Foam 95 g of the following aqueous stock solution was filled into a transparent glass pressure-resistant container and an aluminum pressure-resistant container, a valve was attached, and 5 g of liquefied petroleum gas (* 9) was filled from the valve. Next, carbon dioxide was filled from the valve, and the container was shaken to dissolve the carbon dioxide in the aqueous stock solution and liquefied petroleum gas. The equilibrium pressure at 25 ° C. in the pressure vessel after filling with carbon dioxide was 0.55 MPa.
