Description

Technical Field

[0001] This invention relates to cosmetics. More specifically, this invention relates to cosmetics comprising a combination of a glycine derivative and a specific surfactant. Background Technology

[0002] Cosmetics come in various forms such as toners, lotions, and creams, with toners becoming an indispensable part of basic makeup. Toners contain various ingredients, including water and water-soluble moisturizing agents, as well as non-water-soluble substances such as fragrances, oils, and oil-soluble pharmaceuticals. Various surfactants are used to ensure the stable combination of these ingredients. Furthermore, by using specific surfactants in toners and similar products, superior toners have been developed that remain stable even under harsh conditions such as freezing and high-temperature storage, and exhibit minimal stickiness (Patent Document 1).

[0003] However, toners are required to have a wide variety of properties, which are then matched with various ingredients. In such cases, improving a particular property can sometimes compromise other properties. For example, even when adjusting the surfactant formulation to provide moisture to the skin, a sticky residue or other negative effects may occur after application. Furthermore, while most cosmetics require moisturizing properties, this trade-off can be even more pronounced when using polyols or similar moisturizers.

[0075] The amount of oil in the cosmetic of the present invention is 0.01 to 3% by mass, preferably 0.1 to 1% by mass, and more preferably 0.2 to 0.8% by mass. When the amount of oil is less than 0.01% by mass, the desired effect cannot be obtained, and when it exceeds 3% by mass, the surfactant used to emulsify it also increases, which tends to result in a sticky feel.

[0076] (E) Water

[0077] The cosmetic of the present invention comprises (C) water. The water used in cosmetics, quasi-pharmaceuticals, etc., can be, for example, purified water, ion-exchanged water, tap water, etc.

[0078] (F) Other ingredients

[0079] In addition to the above-mentioned ingredients, the cosmetics of the present invention may also contain any ingredients commonly used in cosmetics and pharmaceuticals. Examples of such ingredients include moisturizers, lower alcohols, thickeners, metal ion chelating agents, neutralizing agents, pH adjusters, antioxidants, preservatives, pharmaceuticals, ultraviolet absorbers, powder components, and (daily) fragrances. As long as the effects of the present invention are achieved, one or more of these ingredients may be used.

[0080] Among these, the cosmetics of the present invention preferably contain moisturizers, particularly polyols. In applications such as toners, moisturizing properties are generally desired; however, moisturizers can sometimes contribute to stickiness when applied to the skin. But in the cosmetics of the present invention, by combining ingredients (A) to (E), stickiness can be suppressed. Therefore, the effects of the present invention are more satisfactory when moisturizers such as polyols are included.

[0081] The cosmetics of the present invention are preferably oil-in-water emulsion cosmetics. The effects of the present invention are particularly advantageous when formulated into transparent or semi-transparent water-based cosmetics such as lotions. The viscosity of the cosmetics of the present invention is not limited, but is generally below 1000 mPa·s, and particularly preferably below 500 mPa·s, which is preferred in terms of skin-friendliness.

[0082] In this invention, "transparent or translucent" refers to a cosmetic product with an L value of 50 or higher in the Hunter Lab colorimetric system. The L value represents the transparency when the transparency of purified water is set to 100 and the condition of no light transmission is set to 0. That is, the closer the L value is to 100, the higher the transparency. The L value can be measured, for example, using a colorimeter such as the Spectrocolor meter SE2000 (manufactured by Nippon Denshoku Co., Ltd.) or the COLOR-EYE 7000A (manufactured by Gretag Macbeth Co., Ltd.).

[0083] Examples of cosmetics that can be exemplified by this invention include skincare products (such as toners, serums, and dressings) and skin cleansers (such as facial cleansers and makeup removers). It should be noted that these are merely examples, and the cosmetics described in this invention are not limited to these methods.

[0084] The cosmetics of the present invention can be manufactured according to conventional methods. When the cosmetics of the present invention are emulsified cosmetics, the emulsification method is not particularly limited.

[0085] Example

[0086] The invention is illustrated by the following examples, but is not limited to these examples. Unless otherwise specified, the content is expressed as a percentage of mass relative to the total amount.

[0087] [Examples 1-4 and Comparative Examples 1-3]

[0088] Oil-in-water cosmetics of Examples 1-4 and Comparative Examples 1-3 were prepared using the formulations shown in Table 1.

[0089] For each cosmetic product, the moisturizing sensation immediately after application was evaluated. Regarding the evaluation, 10 members of the expert panel applied the cosmetic to their skin, and the number of people who rated it as effective compared to the control (Comparative Example 1) was used as the evaluation result.

[0090] In addition, the appearance was observed, and the transparency of the cosmetics was evaluated visually.

[0091] The results are shown in Table 1.
