Description

The present invention comprises a stock solution and a propellant, and the stock solution is an oil containing a water-soluble polymer, one or more selected from titanium oxide, zinc oxide, and iron oxide, water, and liquid oil. It is a medium-water type cosmetic, and the undiluted solution and the propellant have a mass ratio of 30:70 to 50:50, and it relates to an aerosol type cosmetic that is sprayed onto a sponge at the time of use and used on the skin.

In recent years, the number of hot days has increased in the summer. As a result, the demand for cosmetics that give a cool feeling is increasing. For example, aerosol-type cosmetics that give a cool feeling due to the heat of vaporization of liquefied gas as a propellant are preferred, and there are many products on the market. Water-in-oil cosmetics that are resistant to makeup loss due to sweat, etc. are preferred for makeup cosmetics, but many aerosol-type cosmetics are used for makeup including colorants, and so far. An aerosol-type make-up cosmetic that is filled with a water-in-oil emulsification composition containing a polyether-modified silicone having a branched silicone chain as an emulsifier and a propellant in the stock solution, and has excellent redispersibility without gelation and good spreadability. Techniques (Patent Document 1) and the like have been studied.

However, if an aerosol-type cosmetic, especially an aerosol cosmetic for make-up containing a coloring agent, is directly sprayed on the face, etc., it may stain hair and clothes, and it is not easy to apply it evenly. May be used by spraying. When an aerosol-type cosmetic is sprayed on a sponge, most of the undiluted solution is sucked into the sponge due to the strong force of the propellant, and the amount that can be applied to the skin is reduced, which impairs the make-up effect such as covering power, and further. There was a problem that a smooth feel could not be felt due to the friction between the sponge and the skin.
Therefore, it has been desired to develop an aerosol-type cosmetic that has a cool feeling but has a covering power for correcting unevenness and color tone of the skin, has a smooth feel, and is excellent in usability.

In view of such circumstances, as a result of diligent studies, the present inventor forms a cosmetic film having a high covering power capable of correcting a cool feeling and unevenness of the skin and the color tone of the skin, and realizes a smooth feel at the time of application. For that purpose, it was considered necessary to deposit the undiluted solution sprayed on the sponge on the sponge without being sucked. By containing the water-soluble polymer, the void structure formed by vaporization when the liquefied gas mixed in the bulk is injected is maintained, and the mass ratio of the undiluted solution and the propellant is 30:70 to By setting it to 50:50, it was found that the cosmetics were prevented from being sucked into the sponge and the cosmetics were deposited on the sponge, and the sponge did not burden the skin and had a smooth feel and cool feeling when applied to the skin. We have completed an aerosol-type cosmetic that can obtain a cosmetic film with high covering power that corrects unevenness and color tone.

A: Ingredients (1) to (13) are mixed and uniformly dispersed.
B: Ingredients (14) to (18) are mixed, added to A, and emulsified.
After filling 9 g of the undiluted solution obtained in C: B into an aluminum pressure-resistant container (cylindrical shape having a diameter of 35 mm and a height of 11 cm), the valve was fixed, and the propellant (LPG 0.15: 10 g, carbon dioxide gas: 1 g) was passed through the valve. Was filled to obtain an aerosol-type blusher.

The obtained aerosol-type blusher gives a cool feeling, cosmetics are deposited on the sponge, a cosmetic film having excellent covering power is obtained, and has a smooth feel at the time of application, and when the gas is used up. The bulk remaining amount was low.

(Production method)
A: Ingredients (1) to (14) are mixed and uniformly dispersed.
B: Ingredients (15) to (17) were mixed, added to A, and emulsified to obtain a stock solution.
After filling 9 g of the undiluted solution obtained in C: B into an aluminum pressure-resistant container (cylindrical shape with a diameter of 35 mm and a height of 11 cm), the valve is fixed, and the propellant (LPG 0.15: 10 g) is filled in the pressure-resistant container through the valve. Then, an aerosol type eye shadow was obtained.

The obtained aerosol-type eye shadow has a cool feeling, cosmetics are deposited on the sponge, a cosmetic film having excellent covering power is obtained, and it has a smooth feel at the time of application, and the gas is used up. The remaining amount of bulk was low.
