The results are shown in Table 1. The rate of volatilization of carbon dioxide gas and the evaluation of the amount of volatilization are to explain the amount of carbon dioxide gas contained in the foam discharged from the aerosol cosmetic, and to reach a certain amount about 5 minutes after the discharge of the foam.
