According to the aerosol cosmetic of the present invention, by discharging a foamable composition of a specific composition comprising components (A) to (D) from an aerosol container provided with a foam discharging member, the elongated shape of the discharge surface provided by the bubble discharging member A hard foam body on the wall is discharged from each outlet of In a state in which air is blown in or the foam density is small, it is integrated to form a foam body.

Therefore, the foam formed by the aerosol cosmetic of the present invention has a soft skin feel, creamy, and abundant elasticity. In addition, "creamy" means a state in which the foam is dense and smooth. If the foam body to be formed is creamy, the foam does not collapse and lasts for a long time, so there is an advantage in that it firmly adheres to the skin and the application effect is maintained. In addition, if the foam body formed is rich in elasticity, the foam becomes a cushion and the hand does not directly touch the skin, so there is little friction between the hand and the face, and the massage can be continued for a long time without burdening the skin. It has the advantage of increasing.

In particular, when an aerosol cosmetic is used as a cleaning agent, since the foam does not collapse and lasts for a long time, the skin can be washed reliably, and the friction between the hand and the face is reduced because the foam is a cushion and the hand does not directly touch the skin. There is little, and a mild feeling of washing is obtained without burdening the skin.

In addition, when the foaming agent composition forms a wall and foams, it becomes possible to increase the surface area of the foam, and when the foaming agent composition contains a fragrance, the fragrance of the fragrance is improved, and the odor derived from the propellant at the time of spraying is eliminated. It has the advantage that there is no problem to feel strongly.

Moreover, according to the aerosol cosmetics of this invention, the following effects also appear.

· It is also easy to form highly esthetic foam bodies such as a three-dimensional foam body modeled after a flower or a geometric three-dimensional foam body.

· Foam does not flow easily.

· Less clogging of the discharge hole.

· A sufficient amount of foam can be discharged only by short-time operations such as pressing of the pressing unit.
