Description

The present invention mainly relates to water-in-oil type aerosol cosmetics.

In recent years, in the cosmetics industry, aerosol formulations incorporate gas as a propellant, making it possible to create foam-like cosmetics, cosmetics that give a refreshing feeling, and cosmetics that can be easily applied without staining hands. Therefore, demand is increasing. Foam cosmetics have been used for a long time, especially in hair cosmetics.
For example, as shown in Patent Document 1, it is preferred by general consumers because it does not easily drip when applied to the palm of the hand and provides a light feel when spread. By incorporating a water-soluble polymer, it has a good feeling of use and foam quality, has appropriate setting properties, and can suppress flaking when applied to hair. There is a technology for aerosol-type foam hair cosmetics that leave a small amount of hair in the hair.
On the other hand, for non-foamy aerosol cosmetics, from the viewpoint of usability and quality improvement, for example, as described in Patent Document 2, silicone wax with a specific melting point is added to a water-in-oil stock solution. It was discovered that by containing the undiluted solution, the heat of vaporization of the propellant during injection cools and thickens the undiluted solution, preventing the injected undiluted solution from penetrating too much into the sponge. Aerosol-type cosmetics and the like have been proposed, which provide a cosmetic film with a long-lasting feel and high coverage.

However, aerosol foam hair cosmetic technology such as Patent Document 1 often uses a large amount of surfactant as a foaming agent, and even if the foam has good foam retention, it becomes sticky and tends to run off into sebum and sweat. However, when applied in a similar manner to cosmetics applied to the skin, there was a problem in that makeup did not last long. Furthermore, they are often water-based or oil-in-water type stock solutions, and especially when they contain powder, they tend to spread poorly on the skin. Therefore, in order to improve spreadability, when a water-in-oil composition with an oil outer layer is used as a stock solution, the foam retention is even worse than that of a water-based or oil-in-water stock solution. It has been difficult to realize the lightness of the feeling of use due to the inclusion of .
In addition, it has been impossible to improve foam retention only by adding a wax having a specific melting point as in Patent Document 2 to create a thickening effect.
Therefore, as mentioned above, an aerosol cosmetic that uses a water-in-oil composition as its backbone, maintains a non-sticky cosmetic film and long-lasting makeup, and can achieve sufficient foam retention even if powder is added. development was desired.

Therefore, the object of the present invention is to develop an aerosol cosmetic that forms a non-sticky cosmetic film after application, has good makeup retention, and has excellent foam retention.

In view of the above circumstances, the present inventor conducted intensive research and found that the thickening effect produced by blending solid oil and a certain amount of water, and the thickening effect produced by blending an oil-soluble film-forming agent, Focusing on the fact that the stringability of water-in-oil cosmetics can be improved, and that the stringiness of aqueous solutions can be improved by incorporating water-soluble polymers, we have searched for materials that can improve the foam retention of water-in-oil cosmetics. As a result, an oil phase containing a solid oil with a melting point of 25 to 60°C and an oil-soluble film forming agent having a silicone skeleton, and an anionic and nonionic water-soluble polymer having a carbonyl group and/or a hydroxyalkoxy group are selected. Mixing a liquefied gas into a water-in-oil composition obtained by emulsifying one or more types of oil and an aqueous phase containing 30% by mass (hereinafter abbreviated as %) or more of water based on the total amount of the stock solution. We have discovered that it is possible to maintain a non-sticky makeup film and long-lasting makeup while creating a long-lasting foam that spreads well when applied. In addition, we discovered that oil-soluble film-forming agents and water-soluble polymers play a major role in foam retention, and also help with emulsification, and that by keeping the active agent in a certain amount, makeup retention can be further improved. Ta. Furthermore, the present inventors have found that the inclusion of phenyl-modified silicone improves the uniformity of the oily component, resulting in the above-mentioned effects being superior, and the present invention has been completed.

(Evaluation method 1: (a) Good foam retention)
Aerosol cosmetics with good foam retention maintain small, well-sized bubbles in the cosmetic after being sprayed, while aerosol cosmetics with poor foam retention have some of the bubbles coalescing within the cosmetic after spraying. However, large bubbles are generated and burst after a certain period of time. In order to quantitatively evaluate the above-mentioned phenomenon, the following evaluation method of calculating the median size and standard deviation of the bubble size contained in the sprayed cosmetic was used. That is, the aerosol type foundations of Examples 1 to 15 and Comparative Examples 1 to 7 were sprayed onto a glass plate measuring 10 cm long, 12 cm wide, and 250 μm thick so that the weight of the cosmetic was 0.6 g. After 10 seconds had elapsed, a glass plate identical to the above-mentioned glass plate was placed on top of the cosmetic and sandwiched, and the sandwiched cosmetic was adjusted to have a thickness of 100 μm. A still image of the cosmetics sandwiched between the glass plates was taken from the glass plate side using a camera with an effective pixel count of 19.2 million pixels, and the makeup recorded in the above-mentioned still image was taken using the image editing software "Adobe Photoshop". The area of each bubble in the membrane was calculated. Specifically, by measuring the length of the major axis of a specific bubble and calculating the number of pixels of the major axis of the bubble on the same still image as this bubble, the length of one side of one pixel and the area are calculated. did. Then, after calculating the number of pixels of each bubble recorded in the still image, the area of each bubble was calculated by multiplying the number of pixels by the area of 1 pixel. The median value and standard deviation of the area of each bubble were calculated, and each value was evaluated in three ranks according to the evaluation criteria below. Furthermore, the combination of evaluation ranks for each value was determined according to the following criteria.
[Evaluation criteria for the median value of the area of each bubble]
(Rank): (Average score)
A: 0.05 to 1.0 mm ² B: 1.0 to 5.0 mm ² C: Value larger than 5.0 mm ² [Evaluation criteria for standard deviation in area of each bubble]
(Rank): (Average score)
A: 0.05 to 5.0 mm ² B: 5.0 to 12.0 mm ² C: Value larger than 12.0 mm ² [Judgment criteria]
(Judgment): (combination of evaluation ranks)
◎: Median value A and standard deviation A
○: Median value A and standard deviation B, or median value B and standard deviation A
△: Median value B and standard deviation B
×: Either the median or standard deviation is C

(Evaluation method 2: (b) Good spreadability during application, (c) Non-stickiness of the cosmetic film, (d) Good makeup retention of the applied film)
The aerosol type foundations of Examples 1 to 31 and Comparative Examples 1 to 7 were sprayed on a panel of 10 cosmetics evaluation specialists for 2 seconds with the palm of the hand held horizontally at a distance of 2 cm from the aerosol nozzle, and then sprayed on the entire face. Ask them to stretch it out and use it, and check (B) whether the cosmetic can be applied smoothly without feeling any friction between the fingers that are being stretched and the skin, and (C) whether or not the finished makeup film feels sticky when you touch it with your fingers. For items 2 and 2, we asked them to re-evaluate 6 hours later, and each person evaluated whether the coating film had lasted sufficiently on a 5-point scale according to the evaluation criteria below, gave a score to each sample, and then gave a score for all panels. The average score was determined according to the following criteria.

[Evaluation criteria]
(Rating): (Result)
5 points: Very good 4 points: Good 3 points: Fair 2 points: Slightly poor 1 point: Poor

[Judgment 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

This is an example of the present embodiment, and is an evaluation photograph of Example 1 and Comparative Example 4 of the present embodiment, evaluation method 1: (a) foam retention.

As is clear from the results in Table 1, the aerosol foundations of Examples 1 to 31 had good foam retention after spraying, could be fully felt to spread when applied, and did not feel sticky in the applied film, and the makeup retention was also fully satisfactory. On the other hand, in Comparative Example 1, which does not contain component (a), the temperature sensitivity was reduced, so even if the heat of vaporization at the time of spraying was cooled, the thickening effect was insufficient and the foam retention was not satisfactory. In Comparative Example 2, which contains a small amount of component (b), and Comparative Example 4, which contains a small amount of component (c), the foam was prone to coalescence and the foam retention was insufficient. In Comparative Example 3, which contains a large amount of component (b), the makeup film was strongly sticky, which is characteristic of a film-forming agent, friction was felt when applied, and the spread was insufficient. In Comparative Example 5, which contains a large amount of component (c), the stickiness characteristic of a water-soluble polymer was strongly felt, the applied film was easily mixed with sweat over time, and the makeup retention was insufficient. In Comparative Example 6, which contains a small amount of component (d), the thickening effect due to emulsification was not fully obtained, so the foam was prone to coalescence and the foam retention was insufficient. Comparative Example 7, which did not contain component (B) and used only a propellant other than liquefied gas, did not generate enough heat of vaporization when sprayed, so the cosmetic did not thicken and the foam retention was not satisfactory. From the above results, it can be seen that by combining the components of the present invention, it is possible to achieve foam retention that is sufficiently good at spreading when applied, and to obtain an aerosol-type foundation that is non-sticky and has excellent makeup retention.
