LEAVE-ON TYPE AEROSOL COSMETIC COMPOSITION

Abstract

Provided is an aerosol cosmetic composition including carbon dioxide as a propellant and containing at least one ingredient selected from vegetable oil, animal oil and a fatty acid, or an aerosol cosmetic composition further including an alkaline ingredient. The aerosol cosmetic composition causes little skin irritation and can be formulated into a leave-on type formulation which allows direct absorption of a cosmetic product into the skin, and emits little odor unique to the content upon spraying and can provide a glossy foam shape by virtue of the incorporation of carbon dioxide as a propellant.

TEST EXAMPLE 1

Determination of Foam Shape

[0045] The content obtained from each of Examples 1-8 and Comparative Examples 1-8 was introduced to a pressure-resistant can container, valve was clapped thereto and a propellant was filled thereto.

[0046] After filling, the content was sprayed and checked whether it was sprayed in the form of foam (moose). The results are shown in the following Tables 3 and 4.

TABLE-US-00003 TABLE 3 Ex. 1 Ex. 2 Ex. 3 Ex. 4 Ex. 5 Ex. 6 Ex. 7 Ex. 8 Foam Glossy Glossy Glossy Glossy Glossy Glossy Glossy Glossy formation and and and and and and and and and state dense dense dense dense dense dense dense dense foam foam foam foam foam foam foam foam was was was was was was was was formed formed formed formed formed formed formed formed

[0047] As shown in the above Tables, the compositions of Table 1 and Table 2 provided foam upon spraying, and Comparative Examples 5-8 including carbon dioxide provided glossy foam but had a difficulty in absorption as a leave-on type formulation due to an irritating feeling and whitening. In addition, Comparative Examples 1 and 2 allowed use as a leave-on type formulation while forming foam, but it was not possible to obtain glossy foam on the surface, unlike Examples including carbon dioxide. On the contrary, Example 1 using carbon dioxide alone and Examples 2, 3 and 4 using carbon dioxide in combination with another propellant provided glossy foam in the same manner. In the case of Comparative Examples 3 and 4 using an excessive amount of carbon dioxide or a fatty acid. Comparative Example 3 using an excessive amount of carbon dioxide had a difficulty in filling due to a high internal pressure of the container and showed a content-flying phenomenon caused by the strong internal pressure, while not forming foam, when it was filled into a larger container. Thus, it is difficult to obtain foam to be realized according to the present invention. In the case of Comparative Example 4 using an excessive amount of fatty acid, it provided gloss and dense foam but had a difficulty in use to as a leave-on type formulation due to the production of a large amount of soap. Rather, Comparative Example 4 is like a cleansing product departing from the scope of the present invention.

[0048] Further, in the case of Examples, it was possible to obtain dense and glossy foam. When each Example was used for massaging and absorbed to the skin, it showed a soft massaging feeling without whitening and did not cause pruritis and reddish skin. However, in the case of Comparative Examples, it was possible to obtain foam-type content upon spraying but it was not possible to obtain dense and glossy content. Particularly, there was a significant difference between a formulation including carbon dioxide and a formulation including no carbon dioxide. Foam formed by an anionic surfactant capable of bubbling was rich but caused whitening upon massaging and absorption, and thus had a difficulty in commercialization as a leave-on type formulation. Particularly, such foam was problematic in that it caused skin irritation including pruritis after several minutes.

[0049] As can be seen from the Test Example for Examples and Comparative Examples, some combinations are cable of forming foam but there are limited combinations capable of providing glossy and dense foam. When approaching absorbable products, not wash-out products, the ingredients satisfying desired functions are more limited.

TEST EXAMPLE 2

Irritation Test

[0050] A skin patch test was carried out for comparison of irritation feelings. The test method is as follows. A patch was attached to a forearm for 24 hours. to Then, 30 minutes, 24 hours and 48 hours after removing the patch, the forearm was checked according to the terminology defined in the ICDRG guideline and evaluated according to the following criteria (Table 5). The evaluated score of response was calculated according to the following Formula 1 to determine the mean score of response for each content. The Results are shown in the following Table 7.

TABLE-US-00005 TABLE 5 Symbol(grade) Clinical observation (0) None (0.5) Doubtful reaction, faint erythema only +(1) Weak (non-vesicular) reaction, erythema, slight infiltration ++(2) Extreme (bullous or ulcerative) +++(3).sup. Intense erythema with edema & vesicles

[0051] The mean scores of response at 30 minutes, 24 hours and 48 hours were calculated by using the above Formula and the mean score of response for each sample was evaluated according to the criteria of Table 6.

TABLE-US-00006 TABLE 6 Range of Mean Score Criteria 0.00 R < 1.01 Low irritation 1.01 R < 2.01 Light irritation 2.01 R < 3.51 Medium irritation 3.51 R Strong irritation

[0052] As can be seen from Table 7, the aerosol cosmetic composition including, as a surfactant, a fatty acid or vegetable oil, or a fatty acid in combination with vegetable oil is shown to be low irritating and causes little irritation upon skin application, while Comparative Example 4 including an excessive amount of fatty acid and Comparative Examples 4-8 including another type of surfactant cause medium irritation upon skin application.
