Description

The present invention comprises a stock solution consisting of silicone wax, liquid silicone oil, water, water-in-oil cosmetic containing metal oxide powder, and a propellant, which is sprayed onto a sponge at the time of use and used on the skin. 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, 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, which is 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 make-up containing colorants. Especially in the summer, water-in-oil cosmetics that are resistant to makeup loss due to sweat etc. are used as make-up cosmetics. Tends to be preferred as. When using an aerosol-type cosmetic for make-up, spraying it directly on the face may stain hair and clothes, and it is not easy to apply it evenly. There is. So far, the undiluted solution 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, and is an aerosol type that does not gel and has excellent redispersibility and good elongation. Makeup cosmetic technology (Patent Document 1) and the like have been studied.

Japanese Unexamined Patent Publication No. 2011-148757

However, in the technique of Patent Document 1, when an aerosol type cosmetic is sprayed on a sponge, most of the undiluted solution permeates the sponge when a porous sponge is used, and the amount that can be applied to the skin is reduced. There is a problem that the make-up effect such as force may be impaired, and further, the amount of the undiluted solution on the surface of the sponge is small, and the friction between the sponge and the skin makes it impossible to obtain a smooth feel. Therefore, it is desired to develop an aerosol-type cosmetic that does not allow the undiluted solution to permeate too much into the sponge when the aerosol-type cosmetic is sprayed onto the sponge, and that gives a smooth feel at the time of application without impairing the covering power. It was.

In view of this situation, we thought that by first improving the viscosity of the undiluted solution, the undiluted solution would not permeate the sponge too much when the aerosol-type cosmetic was sprayed onto the sponge, and a large amount of powder was contained. However, although the viscosity is increased, a smooth feeling of use may not be sufficiently obtained in some cases. In addition, we tried to contain a water-soluble polymer in the stock solution, but the target quality was slightly not achieved. Therefore, as a result of diligent studies so that other than powder and water-based components do not penetrate too much into the sponge, surprisingly, water in oil containing liquid silicone oil, metal oxide powder, and water at 20 ° C. By containing silicone wax with a specific melting point in the undiluted solution of the mold, the undiluted solution is cooled and thickened by the heat of vaporization of the propellant at the time of injection, so that the injected undiluted solution permeates too much into the sponge. We have found that it will disappear, and have completed an aerosol-type cosmetic that has a smooth feel when applied and can provide a cosmetic film with high covering power.

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

(Production method)
A: Ingredients (1) to (7) were kneaded with three rollers.
In B: A, the components (8) to (18) were heated to 65 ° C. and mixed, and uniformly dispersed.
C: Ingredients (19) to (22) were mixed, added to B, and emulsified at room temperature to obtain a stock solution.
D: After filling the undiluted solution obtained in C 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 (mixed with LPG 87.5% and DME 12.5%) is passed through the valve. Was filled to obtain an aerosol-type foundation.
The stock solution and the propellant were filled in the ratio shown in the table so as to have a total of 32 g.

(Evaluation method 1: (a) Permeation state of undiluted solution into the sponge)
The aerosol type foundations of Examples 1 to 7 and Comparative Examples 1 to 7 were sponge (NBR material, length 45 mm, width 50 mm, thickness 8 mm, weight 3 g, specific gravity 0.16 g / cm ³ , surface hole diameter of 350 μm on average. ) And the injection port of the aerosol type foundation (injection diameter 0.5 mm) were kept horizontal at a distance of 2 cm and injected for 2 seconds. After spraying, the back side of the sponge was visually evaluated, and the permeation state of the undiluted solution into the sponge was evaluated on a three-point scale according to the following evaluation criteria. A score was given to each sample, and the same sample was repeatedly evaluated 10 times to make a judgment according to the following criteria.

[Evaluation criteria]
(Score): (Evaluation)
3 points: Undiluted solution is not observed from the back side of the sponge 2 points: Undiluted solution is slightly observed from the back side of the sponge 1 point: Undiluted 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) Covering power of the coating film, (d) Good cosmetic durability of the coating film)
After spraying the aerosol-type foundations of Examples 1 to 7 and Comparative Examples 1 to 7 on a cosmetic evaluation panel at a distance of 2 cm at a distance of 2 cm for 2 seconds, the entire face. For b, whether it can be applied smoothly without feeling friction between the sponge and the skin, for c, whether it has the covering power of the coating film, and for d, again after 6 hours. After receiving the evaluation, each person evaluates whether the coating film is sufficiently sustained on a 5-point scale according to the following evaluation criteria, gives a score for each sample, and further averages the scores of all panels according to the following criteria. Judged.

[Evaluation criteria]
(Score): (Result)
5 points: Very good 4 points: Good 3 points: Normal 2 points: Slightly bad 1 point: Bad

[Criteria]
(Judgment): (Average score)
◎: 4.5 points or more ○: 3.5 points or more and less than 4.5 points △: 2.5 points or more and less than 3.5 points ×: 1.0 points or more and less than 2.5 points

As is clear from the results in Tables 1 and 2, the aerosol-type foundations of Examples 1 to 7 have less penetration into the sponge in the method of spraying and using the foundations on the sponge, and correct the unevenness of the skin and the color tone of the skin. A cosmetic film having a covering power that can be applied was obtained, and the skin had a smooth feel when applied, and the makeup lasting was sufficiently satisfactory. Although Example 1 has been sufficiently evaluated in these evaluations, Example 2 containing the component (e) is more preferable because it has higher non-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, resistance to the skin by the sponge at the time of application was felt, and the makeup lasted insufficiently. Comparative Example 2 which does not contain the component (b) lacks smoothness at the time of application, gives a high feeling of burden on the skin, tends to cause unevenness in the application film, and has insufficient covering power and makeup retention. Comparative Example 3 which does not contain the component (c) lacks smoothness at the time of application, has a high feeling of burden on the skin, and the coating film is slippery and has low covering power, which is not satisfactory. In Comparative Example 4, in which the component (a) is a silicone wax having a different melting point, the infiltration into 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 oil-based component have insufficient penetration into the sponge and have excellent makeup retention. It wasn't. It is presumed that this is because the wax component has poor compatibility with the component (b) and is micro-localized in the stock solution, so that the entire stock solution cannot be solidified at the time of injection. .. Comparative Example 7, which is a non-silicone wax whose melting point of the component (a) does not match, permeates into the sponge, feels resistance to the skin by the sponge at the time of application, has low covering power, and has long-lasting makeup. It was inadequate. Based on the above results, by combining the components of the present invention, an aerosol that does not penetrate too much into the sponge, provides a cosmetic film with covering power, has a smooth feel when applied, and has excellent makeup retention. You can get a mold foundation.
