Description

  The present invention comprises a stock solution comprising a silicone wax, a liquid silicone oil, water, and a water-in-oil cosmetic containing a metal oxide powder, and a propellant. The present invention relates to an aerosol type cosmetic that does not penetrate too much into the sponge when sprayed onto the sponge.

  In recent years, hot days have increased in summer. This increases the demand for cosmetics that can feel a cool feeling. For example, aerosol-type cosmetics that feel the cool feeling due to the heat of vaporization of liquefied gas as a propellant are preferred, and there are many products on the market. There are many aerosol-type cosmetics not only for skin care but also for makeup including colorants. Especially in summer, water-in-oil cosmetics that are resistant to makeup collapse due to sweat and the like are makeup cosmetics. Tend to be preferred as. When using aerosol type cosmetics for makeup, spraying directly onto the face may stain hair and clothes, and it is not easy to apply evenly. There is. So far, the water-in-oil emulsion composition containing a polyether-modified silicone having a branched silicone chain as an emulsifier in an undiluted solution and a propellant, an aerosol type that has excellent redispersibility without gelation and good elongation A makeup cosmetic technology (Patent Document 1) and the like have been studied.

  However, in the technique of Patent Document 1, when aerosol type cosmetic is sprayed on a sponge, when a porous sponge is used, most of the undiluted solution penetrates into the sponge, which reduces the amount that can be applied to the skin. The makeup effect such as force may be impaired, and there is a problem that a smooth feeling of use cannot be obtained due to friction between the sponge and the skin due to a small amount of the stock solution on the sponge surface. Therefore, there is a demand for the development of aerosol-type cosmetics that, when sprayed with aerosol-type cosmetics, do not penetrate into the sponge too much and do not impair the covering power, and can provide a smooth feeling when applied. It was.

  In view of such a situation, it is thought that by improving the viscosity of the stock solution first, when the aerosol type cosmetic is sprayed on the sponge, the stock solution will not permeate the sponge too much, and a large amount of powder is contained. However, although it thickens, there are cases where a smooth feeling of use cannot be obtained sufficiently. In addition, an attempt was made to include a water-soluble polymer in the stock solution, but the target quality was not achieved slightly. Therefore, as a result of intensive investigations so that the inside of the sponge other than the powder and the aqueous component does not penetrate too much, surprisingly, the water-in-oil containing the silicone oil, the metal oxide powder, and the water that are liquid at 20 ° C. By containing a silicone wax with a specific melting point in the stock solution of the mold, the stock solution is cooled and thickened by the heat of vaporization of the propellant at the time of spraying, so that the sprayed stock solution may penetrate too much into the sponge. The inventors found that it disappeared, and completed an aerosol-type cosmetic that has a smooth feeling during application and provides a decorative film with high covering power.

* 5: KSG-15 (manufactured by Shin-Etsu Chemical Co., Ltd.)

(Production method)
A: Components (1) to (7) were kneaded with three rollers.
B: Components (8) to (18) were heated to 65 ° C. and mixed with A and dispersed uniformly.
C: Components (19) to (22) were mixed, added to B and emulsified at room temperature to obtain a stock solution.
D: After filling the stock solution obtained in C into an aluminum pressure vessel (35 mm diameter, 11 cm high cylindrical shape), the valve was fixed and propellant (LPG 87.5%, mixed with DME 12.5%) through the valve To obtain an aerosol type foundation.
The stock solution and the propellant were filled at a ratio shown in the table so that the total amount was 32 g.

(Evaluation method 1: (I) The state of penetration of the stock solution into the sponge)
The aerosol type foundations of Examples 1 to 7 and Comparative Examples 1 to 7 were made of sponge (NBR material, length 45 mm, width 50 mm, thickness 8 mm, weight 3 g, specific gravity 0.16 g / cm ³ , and surface hole diameter was 350 μm on average. ) And an aerosol-type foundation injection port (injection port diameter: 0.5 mm) were sprayed for 2 seconds while maintaining a horizontal distance of 2 cm. After spraying, the back side of the sponge was visually evaluated, and the state of penetration of the stock solution into the sponge was evaluated in three stages according to the following evaluation criteria. A score was assigned to each sample, the same sample was repeatedly evaluated 10 times, and judged according to the following criteria.

[Evaluation criteria]
(Score): (Evaluation)
3 points: The stock solution is not observed from the back side of the sponge 2 points: The stock solution is slightly observed from the back side of the sponge 1 point: The stock solution is observed from the back side of the sponge

[Criteria]
(Judgment): (Average score)
◎: 2.5 points or more ○: 2.0 points or more and less than 2.5 points ×: 1.0 points or more and less than 2.0 points

(Evaluation method 2: (b) Smoothness when applied with a sponge, (c) Cover strength of the coated film, (d) Goodness of makeup of the coated film)
After spraying the aerosol-type foundations of Examples 1-7 and Comparative Examples 1-7 to sponge and aerosol spray ports at a distance of 2 cm for 2 seconds while maintaining the level for 10 seconds, 10 face panels specializing in cosmetics were evaluated. In the case of (2), whether or not it can be applied smoothly without feeling friction between the sponge and the skin; Evaluate and evaluate whether the coated film is sufficiently long, according to the following evaluation criteria, and give a five-point score for each sample. Furthermore, the average score of all panels according to the following criteria Judged.

  As is apparent from the results of Tables 1 and 2, the aerosol foundations of Examples 1 to 7 have less penetration into the sponge and correct skin irregularities and skin tone in the method of spraying onto the sponge and using it. A covering film that has a covering power that can be applied was obtained, had a smooth feel during application, and was sufficiently satisfactory for makeup. Although Example 1 has obtained sufficient evaluation in these evaluations, Example 2 including the component (e) is more preferable because it has a higher penetration and higher covering power than Example 1. On the other hand, in Comparative Example 1 containing no component (a), permeation into the sponge was observed, and the resistance to the skin due to the sponge at the time of application was felt, and the makeup lasting was insufficient. Comparative Example 2 containing no component (b) lacked smoothness during application, had a high feeling of burden on the skin, and the coating film was likely to be uneven, and the covering power and makeup lasting were insufficient. Comparative Example 3 containing no component (c) was not satisfactory because it lacked smoothness during application, had a high feeling of burden on the skin, and the coating film was slippery and the covering power was low. In Comparative Example 4 where the component (a) is a silicone wax having a different melting point, the penetration of the sponge is insufficient, and the resistance of the sponge is easily felt at the time of application. Was also not good. Although the melting points of the component (a) match, Comparative Example 5 and Comparative Example 6 containing a non-silicone paste-like or solid oily component have insufficient penetration into the sponge and have excellent cosmetic durability. It was not. This is presumably because the wax component is poorly compatible with component (b) and is micro-localized in the stock solution, so that the whole stock solution cannot be solidified during injection. . In Comparative Example 7, which is a non-silicone wax whose melting point of component (a) does not match, penetration into the sponge is observed, the resistance to the skin due to the sponge at the time of application is felt, the covering power is low, and the cosmetic durability is also low. It was insufficient. From the above results, by combining each component of the present invention, a cosmetic film having a covering power that does not penetrate too much into the sponge is obtained, and has a smooth feeling during use and excellent in long-lasting makeup. A mold foundation can be obtained.
