Description

Aerosol cosmetics

The present invention relates to an aerosol container having a foam discharge member and an aerosol cosmetic having a foamable composition filled in the aerosol container.

In foaming compositions such as facial soap, shampoo, shaving foam, etc. that produce a foam (foam) in which a gas and a large number of bubbles consisting of a liquid film surrounding the gas are connected by a predetermined operation, the foam is rich in creamy and elastic In order to lengthen the time until the body is formed or the foam disappears, an oil or fat component such as a fatty acid or a metal soap such as a fatty acid soap is included in the composition.
Patent Document 1 describes that a fatty acid salt is added to a cleaning composition, which is a foamable composition, in addition to N-acylglycine or a salt thereof and an inorganic salt.

In addition, various foamable compositions have been proposed in which an aerosol container is filled with a stock solution such as a cleaning composition and a propellant and discharged as a foam using a gas for injection. For example, Patent Document 2 discloses: There is described a foamable aerosol product comprising a foamable composition containing a stock solution and a liquefied gas, an aerosol container filled with the foamable composition, and a discharge member attached to the aerosol container.
The foamable aerosol product of Patent Document 2 is mainly intended for the formation of a lightweight foam. As the foamable composition, a mixture of an aqueous stock solution and a liquefied gas at a specific mass ratio is used. By using a discharge member that has a foaming space and a discharge surface that closes the foaming space and has a number of discharge holes, the foamable composition injected into the foaming space foams in the foaming space. Thus, the elongated first foam body that has passed through a large number of ejection holes is joined to the second foam body while entraining air outside the ejection surface.
Patent Document 2 also describes that an aqueous stock solution contains a fatty acid soap or the like as an anionic surfactant.

According to the aerosol cosmetic composition of the present invention, the foaming composition having the specific composition containing the components (A) to (D) is ejected from the aerosol container provided with the foam ejection member, whereby the ejection surface of the foam ejection member is provided. A wall-like stiff foam is discharged from each of the elongated discharge ports, and there are a plurality of discharge holes independently in the radial direction from the center of the discharge surface to the outer periphery of the discharge surface. When the foam discharged from the outlet forms a wall and foams, the foam is integrally formed in a state where air is taken in between the walls or in a state where the foam density is low.
Therefore, the foam formed by the aerosol cosmetic composition of the present invention has a soft touch per skin, and is creamy and rich in elasticity. “Creamy” means a state in which bubbles are dense and smooth. If the foam formed is creamy, the foam does not collapse and lasts long, so that there is an advantage that the coating effect is firmly adhered to the skin and the application effect is sustained. Also, if the foam that is formed is highly elastic, the foam becomes a cushion and the hand does not touch the skin directly, so there is less friction between the hand and the face, and massage can be continued for a long time without placing a burden on the skin. There is an advantage that the makeup effect is enhanced.
In particular, when using aerosol cosmetics as a cleaning agent, the foam does not collapse and lasts long, so the skin can be washed firmly, and the foam acts as a cushion so that the hand does not touch the skin directly. It has a low friction and gives a mild feeling of washing without imposing a burden on the skin.
Furthermore, the foaming agent composition foams in the shape of a wall, so that it becomes possible to increase the surface area of the foam. When the foaming agent composition contains a fragrance, the fragrance of the fragrance is improved and spraying is performed. There is an advantage that there is no problem that the odor derived from the propellant is sometimes felt strongly.

Furthermore, according to the aerosol cosmetics of the present invention, the following effects are also exhibited.
-It is easy to form highly aesthetic foams such as three-dimensional foams that simulate flowers and geometric three-dimensional foams.
-Bubbles are less likely to sag.
・ There is little clogging of the discharge hole.
-A sufficient amount of foam can be discharged just by pressing the pressing operation unit for a short time.
