Description

The present invention relates to aerosol cosmetics.

Aerosol cosmetics using carbon dioxide have been studied in order to promote blood flow, heat effect, and massage effect. For example, Patent Document 1 describes a foam-like cosmetic composition containing carbon dioxide gas, and Patent Document 2 describes a foam cosmetic composition containing carbon dioxide gas and solid fat and having a warming effect. .. Further, Patent Document 3 describes a cosmetic in which percutaneous absorption of carbon dioxide gas is promoted with fine bubbles and has no stickiness immediately after spreading, and in Patent Document 4, it is easy to massage and is rinsed off after massage. Aerosol type cosmetics having a good feeling after application are described.

However, the cosmetics described in Patent Document 1 and Patent Document 2 have a problem of foam spread, and it is not assumed that the foam containing carbon dioxide gas is quickly adapted to the skin. The cosmetics described in Patent Document 3 have fine bubbles and suppressed stickiness, but they were not sufficient in terms of the spread of the bubbles and the feeling of penetration into the skin. Although the massage agent described in Patent Document 4 has good spreadability for massaging, it does not assume a feeling of penetration into the skin.

Production Example 1 (Production of resin powder A)
82 g of lauryl methacrylate, 3 g of methacrylic acid, 15 g of ethylene glycol dimethacrylate, and 2 g of lauroyl peroxide were charged into a beaker and mixed and stirred to dissolve. 400 g of ion-exchanged water in which 0.75 g of sodium N-stearoyl-N-methyltaurine (SMT) was dissolved was added thereto, and dispersed with a homomixer until the average particle diameter became 2.2 μm. This dispersion was poured into a four-necked flask, and nitrogen replacement was carried out for 30 minutes while stirring. The temperature inside the flask was raised to 80° C. by an oil bath, and after reaching 80° C., polymerization was carried out for 5 hours and then cooled to room temperature. 3.9 g of 1N NaOH was added dropwise to the dispersion of polymerized particles for neutralization, and then the dispersion was freeze-dried and the particles were collected to obtain resin powder A (lauryl methacrylate/ethylene dimethacrylate). Glycol/sodium methacrylate) was obtained. This resin powder A had a carboxyl group neutralization degree of 11.2%.

Examples 1-2 and Comparative Examples 1-4
Aerosol cosmetics having the composition shown in Table 1 were produced, and the viscosity of the undiluted solution was measured at 25°C, and the spread of foam, the feeling of penetration of the foam into the skin, the feeling of skin film after application, and the familiarity with lotion were evaluated. did. The results are also shown in Table 1.

(Production method)
The components (A), (D) and (E) were stirred at 60° C., and a base was further mixed and stirred. Then, the components (B) and (C) and the rest of the components were added, and the mixture was stirred to homogenize it and cooled to 25°C to obtain a stock solution. The obtained stock solution was filled in a pressure resistant container, sealed, and then filled with the component (F) to obtain an aerosol cosmetic.

(Evaluation method)
(1) Spread of bubbles:
0.2 g of each cosmetic was discharged onto a black A4 size polypropylene underlay, placed so that the major axis of the underlay was perpendicular to the ground, and allowed to stand for 30 seconds. The length was measured and evaluated according to the following criteria. The results are shown as a total of 5 points.
5; extended longer than 20 cm.
4; extended from 18 cm to 20 cm or less.
3; extended from 16 cm to 18 cm or less.
2; extended from 14 cm to 16 cm or less.
1; it reached to 14 cm or less.

(2) Permeation of bubbles into the skin (quantitative evaluation):
0.1 g of each cosmetic was discharged onto the skin on the inner side of the forearm and massaged into a circle having a diameter of 3 cm at a speed of 2 rotations per second for 10 seconds.
The friction (a) immediately after and the friction (b) 1 minute after that were measured, and the value of (b)-(a) was calculated. The friction was measured with a handy rub tester manufactured by trilab under a load of 10N.
The friction has a small value when the cosmetic remains on the skin because the resistance is small, and has a large value when the cosmetic does not remain because the resistance increases. Therefore, by calculating the value of (b)-(a), the extent to which the cosmetic penetrated the skin was evaluated from the remaining condition of the cosmetic. The larger the value of (b)-(a), the better the permeation feeling.

(3) Permeation of bubbles into the skin (sensory evaluation):
Five professional panelists discharged 0.1 g of each cosmetic onto the skin inside the forearm, massaged it into a size of 3 cm in diameter at a speed of 2 revolutions per second for 1 minute, touching the skin immediately afterwards, and foaming. The feeling of penetration was evaluated. The criteria are 5 levels, with 5 being "there is a clear feeling of permeation of bubbles" and 1 being "no feeling of permeation of bubbles". In addition, the feeling of penetration means that the liquid of the cosmetic does not remain on the applied skin. The results are shown by the total score of 5 persons.

(4) Skin film feeling after application:
Five professional panelists discharged 0.1 g of each cosmetic onto the skin on the inside of the forearm, massaged it into a size of 3 cm in diameter at a speed of 2 revolutions per second for 1 minute, and touched the skin immediately afterwards to give a film. The feeling was evaluated. The criteria were 5 levels, with 5 being "clearly has film feeling" and 1 being "no feeling of film feeling". The results are shown by the total score of 5 persons.

(5) Facial lotion:
Five professional panelists discharged 0.1 g of each cosmetic onto the skin on the inside of the forearm and massaged into a size of 5 cm in diameter at a speed of 2 revolutions per second for 1 minute, and then commercial lotion ( 0.2 g of lotion 1) was applied and massaged for 20 seconds in the same manner, and the skin immediately after that was touched, and the familiarity was evaluated. Familiarity indicates that no skin lotion remains on the skin after massage. The criteria are 5 levels, with 5 being "clearly lacking lotion" and 1 being "clearly remaining lotion". The results are shown by the total score of 5 persons.
