Description

  The present invention relates to an aerosol cosmetic.

  Aerosol cosmetics using carbon dioxide gas have been studied to promote blood flow, heat effects, and massage effects. For example, Patent Document 1 describes a foam cosmetic containing carbon dioxide, and Patent Document 2 describes a foam cosmetic that contains carbon dioxide and solid fat and has a warming effect. . Further, Patent Document 3 describes a cosmetic material that promotes percutaneous absorption of carbon dioxide gas with fine bubbles and has no stickiness immediately after spreading, and Patent Document 4 is easy to massage and rinse after massage. Aerosol-type cosmetics are described that have a good feel after a long time.

  However, the cosmetics described in Patent Document 1 and Patent Document 2 have a problem in spreading the foam, and do not assume that the foam containing carbon dioxide gas is quickly adapted to the skin. The cosmetic described in Patent Document 3 has fine foams and has reduced stickiness, but is not sufficient in terms of foam expansion and skin penetration. Although the massage agent described in Patent Document 4 has a good stretch for massaging, it does not assume a sense of penetration into the skin.

The dispersion was poured into a four-necked flask and purged with nitrogen for 30 minutes while stirring. The temperature inside the flask was heated to 80 ° C. with an oil bath. After reaching 80 ° C., polymerization was performed for 5 hours, and then cooled to room temperature. After neutralizing the dispersion of polymerized particles by dropwise addition of 3.9 g of 1N NaOH, the dispersion was freeze-dried and the particles were collected to recover resin powder A (lauryl methacrylate / ethylene glycol dimethacrylate). -Sodium methacrylate was obtained. This resin powder A had a carboxyl group neutralization degree of 11.2%.

(2) Foam penetration into 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 with a diameter of 3 cm for 10 seconds at a speed of 2 revolutions per second.
The immediately following friction (a) and the friction (b) after 1 minute were measured, and the value of (b)-(a) was calculated. The friction was measured using a handy rub tester manufactured by trilab with a load of 10N.
Friction takes a small value when the cosmetic is left on the skin because the resistance is low, and takes a large value when the cosmetic is not left because the resistance is increased. Therefore, by calculating the value of (b)-(a), it was evaluated how much the cosmetic penetrated into the skin from the remaining condition of the cosmetic. The larger the value of (b)-(a), the better the penetration feeling.

(3) Foam penetration into the skin (sensory evaluation):
Five professional panelists discharge 0.1g of each cosmetic material onto the skin inside the forearm, massage to a diameter of 3cm for 1 minute at a speed of 2 revolutions per second, touch the skin immediately after, and foam The penetration feeling of was evaluated. The standard was set to 5 levels, with 5 indicating “there is a clear feeling of foam penetration” and 1 being “not the feeling of foam penetration at all”. The penetrating feeling indicates that no cosmetic liquid remains on the applied skin. The result was shown by the total score of 5 persons.

(4) Skin feeling after application:
By 5 expert panelists, each cosmetic 0.1g is discharged onto the skin on the inner side of the forearm, massaged to a size of 3cm for 1 minute at a speed of 2 rotations per second, touching the skin immediately after, The feeling was evaluated. The criteria were five levels, with 5 being “feeling of film feeling clearly” and 1 being “not feeling film feeling at all”. The result was shown by the total score of 5 persons.

(5) Familiarity familiarity:

The aerosol cosmetics of Examples 3, 5 to 10 and 13 were evaluated in the same manner as in Test Example 2 for “familiarity with lotion”. The results are shown in Table 4.

Test Example 4 (Examples 15 and 16, Comparative Examples 5 to 8)
In the same manner as in Examples 1 and 2, aerosol cosmetics having the compositions shown in Table 5 were produced, and foam spread, foam penetration into the skin, and skin feel after application were evaluated. Further, in the same manner as in Test Example 2, “familiarity with lotion” was evaluated. The results are also shown in Table 5.

Test Example 5
In the case where the aerosol cosmetic of Example 1 and a commercially available lotion (hereinafter referred to as lotion 2) are used in combination (Method 1), and the case where only the lotion 2 is used (Method 2), the lotion is easily spread. The uniform adhesion to the skin and the familiarity of the lotion were evaluated. The results are shown in Table 6.

(Evaluation method)
(1) Ease of lotion:
(Method 1)
By spraying 0.1 g of the aerosol cosmetic composition of Example 1 onto the skin on the inner side of the forearm by 5 dedicated panelists, massaging the skin to a size of 5 cm for 1 minute at a speed of 2 revolutions per second, then lotion When 0.2 g of 2 was applied and similarly massaged for 20 seconds, the ease of spreading of the applied lotion 2 was evaluated. The criteria were five levels, with 5 being “easy to extend” and 1 being “not easy to extend”. The result was shown by the total score of 5 persons.
(Method 2)
Evaluation was performed in the same manner as in Method 1 except that the aerosol cosmetic composition of Example 1 was not used.

(2) Uniform adhesion to the skin:
(Method 1)
0.03 g of the aerosol cosmetic material of Example 1 was applied to the skin on the inner side of the forearm in a size of 3 × 7 cm ² and applied uniformly. Then, 0.01 g of skin lotion 2 in which 100 ppm of distyryl biphenyl disulfonic acid 2Na (Tinopearl CBS-X, manufactured by Ciba Specialty Chemicals), which is a water-soluble fluorescent agent, was applied and black light (black light blue FPL27BLB 27 Watts) was applied. Sanyo Denki Co., Ltd.) and a digital single-lens camera (model: EOS 60D, lens: EF100mm F2.8 Macro USM, manufactured by Canon Inc.) were used to take a picture of the coated area. From the photograph, the distribution of the cosmetic 2 was visually evaluated by five professional panelists. The criteria were 5 levels, with 5 being “uniformly attached” and 1 being “not uniformly attached”. The result was shown by the total score of 5 persons.
(Method 2)
Evaluation was performed in the same manner as in Method 1 except that the aerosol cosmetic composition of Example 1 was not used.
An image of the photograph taken is shown in FIG.

(3) Familiarity familiarity:
(Method 1)
Evaluation was conducted in the same manner as in Test Example 2 except that lotion 2 was used as the lotion.
(Method 2)
Evaluation was performed in the same manner as in Method 1 except that the aerosol cosmetic composition of Example 1 was not used.

Examples 17 and 18
In the same manner as in Examples 1 and 2, aerosol cosmetics having the compositions shown in Tables 7 and 8 were produced.
The obtained aerosol cosmetics have good foam spreading, excellent foam penetration into the skin, and a film feel on the coated skin. Moreover, the penetration feeling of the other cosmetics used after apply | coating the aerosol cosmetics of this invention to skin improves.

Reference example 1
The aerosol cosmetic composition of the present invention is applied or applied to the skin, and then applied or applied to another skin composition other than the present invention on the skin to which the aerosol cosmetic composition is applied or applied. The penetrating feeling is improved and the spread of the other cosmetics is improved.
Thus, although it does not restrict | limit especially as another cosmetics used after the aerosol cosmetics of this invention, As an example, the lotion of the composition shown in Table 9 is mentioned.
