The cosmetic composition containing a fatty acid or a fatty acid soap has a problem in that when it is spit out from an aerosol container, the formed foam is heavy, and the skin of the foam is felt to be hard. Therefore, as in Patent Document 2, it is also conceivable to release the foam from a plurality of discharge ports, and thereafter to combine the discharged bubbles, thereby containing air inside to improve the foam, but consisting of a fatty acid or a fatty acid soap. The foam produced by the cosmetic composition is difficult to bond due to the fact that the foam itself is hard, so that it is difficult to sufficiently improve the foam. Further, the cosmetic composition containing a fatty acid or a fatty acid soap has a weak aroma emission even when it contains a fragrance, and when a propellant having a odor such as dimethyl ether is used, the odor from the propellant is strongly felt upon ejection. The question of taste, but there is no research on these issues. On the other hand, in Patent Documents 3 and 4, an aerosol container in which discharge ports of various shapes are formed has been proposed from the viewpoint of aesthetics, but there has been no research on controlling foam and aroma emission.

The present invention is directed to providing an aerosol cosmetic that solves the problems of the above-described prior art.

The inventors of the present invention have found that a specific foaming composition containing a fatty acid or a salt thereof is discharged from an aerosol container having a bubble discharge member having a discharge hole having a specific shape, thereby becoming a soft-feeling foam. The effect of improving the foam quality and the aroma emission are also improved, thereby completing the present invention.

[evaluation standard]

5 points: very good

4 points: better

3 points: Unable to judge (equivalent to Comparative Example 1)

2 points: poor

1 point: very bad

[Evaluation of cleaning effect]

The iron oxide colored simulated sebum was applied to the back of the hand, and after 30 minutes passed, the sample 1 g was used, and the back of the hand was massaged for 1 minute at a certain force and speed, and then rinsed with water. For the cleaning effect after rinsing, the standard was divided into four stages, and the state in which the coloration caused by the simulated sebum was largely removed was set to 4, and the state in which the coloring caused by the simulated sebum was not largely removed was evaluated as 1. The results are shown in Tables 1 and 2 in the form of an average score of 5 people (the second place after the decimal point is rounded off).

[Evaluation of foam durability (shape maintenance)]

After the foam was discharged, the foam was allowed to stand for 3 minutes, and the shape change of the foam was visually observed, and the foam durability (shape maintainability) was evaluated based on the following evaluation criteria. The evaluation results are shown in Tables 1 and 2.

[evaluation standard]

A: Maintain the shape that is roughly the same as when it is spit.

B: Although the shape of the bubble end is rounded compared with the time of discharge, the overall shape is maintained.

C: The overall shape is deformed compared to when it is spit.

X: It is completely impossible to maintain the shape when spitting.

* 1: The bubble is soft and the bubble is immediately deformed after the discharge, so that the shape change cannot be evaluated.

* 2: The bubble is too hard, so the bubble is not sufficiently ejected when it is spouted, and each shape does not form a certain shape.

[Evaluation of the difficulty of clogging]

After the foam is spit out, the bubbles on the discharge surface are removed and placed in the room. After one day, it was confirmed whether or not there was a blockage of the discharge hole, and when there was a blockage, it was also investigated whether or not the discharge property was affected. The evaluation results based on the evaluation criteria described below are shown in Tables 1 and 2.

[evaluation standard]

A: No blockage occurred.

B: Blockage was observed, but spit out from all the discharge holes.

X: Blockage was observed, and a spit hole which was not sputtered was observed.

[Bubble hardness]

The foam was discharged and filled into a 100 mL beaker up to 90 mL, and measured using a B-type viscometer (VISMETRON viscometer: Model VS-A1, manufactured by Shibaura System Co., Ltd.) under spindle number 4, 12 rpm (revolutions per minute), 30 seconds. The viscosity of the bubble.

[Neutralization rate]

The neutralization ratio was calculated from the saponification value X of each fatty acid by the following formula.

Neutralization rate (%) = potassium hydroxide content / Σ ((X / 1000) × fatty acid content)

(industrial availability)

According to the aerosol cosmetic of the present invention, the foaming composition containing the specific composition of the components (A) to (D) is discharged from the aerosol container having the bubble discharge member, and the discharge is provided from the bubble discharge member. A plurality of discharge holes are formed in the radial direction of the outer peripheral portion of the discharge surface from the center portion of the discharge surface, and the discharge port is discharged from the discharge port. The foam body is formed into a wall shape and foamed, thereby integrating the air into a state between the walls or a state in which the bubble density is small to form a bubble body. Therefore, the foam formed by the aerosol cosmetic of the present invention becomes a soft, thick and elastic touch. Furthermore, the term "thick" refers to a state in which the bubbles are dense and smooth. If the formed foam is thick, there is an advantage that the foam is kept for a long time without being broken, so that it is closely adhered to the skin, and the application effect is long-lasting. Moreover, if the formed bubble body is elastic, it has the following advantages: the bubble becomes a buffer The hand does not directly contact the skin, so the friction between the hand and the face is less, and the massage can be continued for a long time without exerting a burden on the skin. Especially when the aerosol cosmetic is used as a cleaning material, since the foam is kept for a long time without being broken, the skin can be surely cleaned, and since the bubble becomes a buffer and the hand does not directly contact the skin, the hand and the face are between It has less friction and does not put a burden on the skin, so you can get a gentle wash. Further, by foaming the foaming agent composition into a wall shape, there is an advantage that the surface area of the foam body can be enlarged, and when the foaming agent composition contains a flavor, the fragrance of the flavor is increased, and when it is sprayed. It is strongly felt that the problem of the odor from the propellant also disappears.

Further, the aerosol cosmetic according to the present invention also exerts the following effects.

. It is also easier to form a bubble having a higher aesthetic value, such as a bubble shape of a three-dimensional shape of a flower or a bubble body of a geometric three-dimensional shape.

. It is not easy to cause dripping of bubbles.

. There is less blockage in the spit hole.

. A sufficient amount of bubbles can be discharged by performing an operation such as pressing the operation portion for a short period of time.
