Description

The present invention relates to an external composition that has good skin compatibility at the time of application and can impart an excellent glossiness.

In recent years, in response to increasing demand for improved functionality and diversification of skin care products, skin care products having various functionalities have been developed. In particular, among the functionality of skin care products, giving a glossy feeling (that is, the glossiness of a fresh and moist texture) is one of the functions that consumers are highly interested in and demanding.

Conventionally, various skin care products that give a glossy feeling to the skin have been studied. For example, Patent Document 1 describes a skin care or cleansing composition containing a predetermined amount of solid single crystal flat plate particles having a refractive index of 1.8 to 2.2 and having an impermeable property of less than about 20%. , It is disclosed that it can give a glossy feeling to the skin. However, in the composition of Patent Document 1, the flat plate-like particles merely give the skin a glossy appearance, and do not enhance the function inherently possessed by the skin to give a glossy feeling. Further, Patent Document 2 contains a higher alcohol, a higher fatty acid, a base, a (alkyl-modified) carboxyvinyl polymer, a polysaccharide, an oil agent (other than the higher alcohol and the higher fatty acid), and an aqueous solvent in a predetermined ratio and content. It is disclosed that skin cosmetics can form a uniform and flexible lamellar α-gel structure film on the skin surface to give a glossy feeling to the skin. However, even with the skin cosmetics of Patent Document 2, the skin is merely provided with a glossy feeling by forming a film on the skin, and the skin is not given a glossy feeling by enhancing the function of the skin itself. ..

As described above, in the techniques of Patent Documents 1 and 2, since the appearance of the component itself applied to the skin merely artificially expresses a glossy feeling, there is a drawback that the glossy feeling is lost when the skin is washed. There is.

In recent years, there has been an increasing demand for higher functionality and improved usability of external compositions, and the glossiness artificially expressed as in Patent Documents 1 and 2 can sufficiently follow the demands of consumers. It's gone. Therefore, in order to meet the demands of consumers, it is desired to develop an external composition that can give a glossy feeling by enhancing the original function of the skin and has a good usability.

Test Example 1
1. 1. Preparation of External Composition (Liquid) An external composition (liquid) having the compositions shown in Tables 1 to 3 was prepared. Specifically, a predetermined amount of the senkyu extract, egg yolk lecithin, macadamia nut oil, jojoba oil, and polyoxyethylene hydrogenated castor oil 60 shown in Tables 1 to 3 are mixed, and this is added to purified water and stirred. , An external composition (liquid agent) was obtained.

2. Evaluation and evaluation of skin familiarity and glossiness The skin familiarity and glossiness of each liquid agent were evaluated by 10 monitors. Specifically, 0.5 g of each liquid was applied to the back of the hand, and the perceived skin familiarity and glossiness were evaluated.

The evaluation of skin familiarity was performed by conducting a questionnaire using the Visual Analogue Scale (VAS), with "1" indicating that the skin was not familiar to the skin at the time of application and "10" being the feeling that the skin was familiar to the skin at the time of application. The evaluation results were summarized by averaging the questionnaire results and rounding off to the first decimal place.

In addition, the glossiness is evaluated 5 minutes after the first application on the first day in a state where the skin is not washed (that is, a state in which the external composition is applied), and continuous use for 7 days (every morning and evening). Evaluation was made in the state after washing the skin after application) (that is, the state in which the external composition was not applied). The glossiness was evaluated by conducting a questionnaire using the Visual Analogue Scale (VAS), with the feeling of poor glossiness being "1" and the feeling of glossiness being "10". The evaluation results were summarized by averaging the questionnaire results and rounding off to the first decimal place. The evaluation in the state where the external composition was applied was performed only in Examples 8, 13, 14, 19, 20 and Comparative Examples 4, 9, and 10. In this test, the glossiness in the "state in which the external composition is applied" is not only the glossiness of the skin itself, but also the glossiness exhibited by the presence of the external composition on the skin. The glossiness in the "state where the external composition is not applied" is evaluated only by the glossiness of the skin itself (that is, the glossiness based on the function that the skin originally has). You will be doing.

The results obtained are shown in Tables 1 to 3. As is clear from Table 1, the external composition containing the Senkyu extract alone did not show a satisfactory effect on both skin compatibility and glossiness (Comparative Examples 1 to 4). In addition, when animal oil and vegetable oil were used alone, the skin compatibility was improved and the glossiness when the external composition was applied was higher than that when the senkyu extract was used alone, but the external composition was improved. The glossy feeling in the uncoated state was not a satisfactory result (Comparative Examples 5 to 10). On the other hand, when 0.0001% by weight or more of Senkyu extract in terms of dry weight is used in combination with animal oil and / or vegetable oil, it is familiar to the skin and glossy when the external composition is not applied. Both feelings were improved (Examples 1 to 20). In particular, when 0.0001% by weight or more of Senkyu extract, egg yolk oil, and macadamia nut oil or jojoba oil are combined in terms of dry weight, they are familiar to the skin and have a remarkably glossy feeling when no external composition is applied. (Examples 17 to 20). Further, in Examples 17 to 20, the improvement rate of the glossiness in the state where the external composition is not applied is high, and it gives the impression that the entire skin is covered with the oil produced by the skin. It was able to give a moist and glossy feeling.
