[Solution] One embodiment of the cosmetic composition according to the present disclosure comprises (A) a sheet containing an organically modified clay mineral and (B) a liquid composition containing a surfactant, wherein before use, the liquid composition containing the surfactant (B) is brought into contact with the sheet containing the organically modified clay mineral (A).

Description

[Technical Field] 【0001】 This disclosure relates to cosmetics, kits, and liquid compositions. [Background technology] 【0002】 Conventionally, two-part sheet masks and other cosmetics have been widely used, in which a liquid cosmetic composition is brought into contact with a nonwoven fabric or similar sheet immediately before use, and then applied to the face or other areas. These cosmetics aim to achieve high cosmetic effects such as lifting and skincare by covering the face or other areas with a sheet impregnated with a liquid cosmetic composition for a certain period of time. 【0003】 To date, a technology has been proposed to provide a sheet-type cosmetic pack that is easy to handle as a dry type, has excellent adhesion to the skin, remains soft and adheres well even when dry, does not easily lift away from the skin, and easily exhibits pack effects such as heat retention and moisturizing effects. This cosmetic pack consists of a dry sheet-type nonwoven fabric mask on which a specific water-soluble polymer is supported, and a lotion containing specific ingredients, and the nonwoven fabric mask is moistened and softened with the lotion before use (see Patent Document 1). [Prior art documents] [Patent Documents] 【0004】 [Patent Document 1] Japanese Patent Publication No. 2016-155764 [Overview of the Initiative] [Problems that the invention aims to solve] 【0005】 However, conventional technology does not provide sufficient adhesion to the skin, and there is room for further improvement. 【0006】 Furthermore, while oil-based beauty serums, a type of oil-based cosmetic, have become popular in the market in recent years, sheet cosmetics impregnated with oil-based beauty serums have yet to appear on the market. This is presumably because oil-based beauty serums, which are comfortable and suitable for the skin, have low surface tension and low viscosity, so impregnating them into a sheet would cause "dripping" and prevent the sheet from adhering properly to the skin. 【0007】 In view of the above, one aspect of this disclosure aims to provide a cosmetic composition that has excellent adhesion to the skin and is also applicable to oily liquid compositions. [Means for solving the problem] 【0008】 To solve the above problems, one embodiment of the cosmetic composition according to the present disclosure comprises (A) a sheet containing an organically modified clay mineral and (B) a liquid composition containing a surfactant, wherein before use, the liquid composition containing the surfactant (B) is brought into contact with the sheet containing the organically modified clay mineral (A). [Effects of the Invention] 【0009】 According to one aspect of this disclosure, it is possible to provide a cosmetic composition that has excellent adhesion to the skin and can also be applied to oily liquid compositions. [Modes for carrying out the invention] 【0010】 The embodiments of this disclosure will be described in detail below. However, the embodiments are not limited to the following description and can be modified as appropriate without departing from the gist of this disclosure. Furthermore, in this specification, the "~" indicating a numerical range means that the numbers before and after it are included as the lower and upper limits, respectively, unless otherwise specified. 【0011】 (Cosmetics) A cosmetic composition according to one embodiment comprises (A) a sheet containing an organically modified clay mineral and (B) a liquid composition containing a surfactant, and optionally includes other components. In the cosmetic composition according to one embodiment, before use, the liquid composition containing the surfactant (B) is brought into contact with the sheet containing the organically modified clay mineral (A). 【0012】 As mentioned above, sheet cosmetics impregnated with oil-based serums have not yet appeared on the market. This is presumably because oil-based serums that are comfortable and suitable for the skin have low surface tension and low viscosity, which would cause "dripping" when impregnated into a sheet, and the sheet would not adhere properly to the skin. 【0013】 Furthermore, it is extremely difficult to moderately thicken oil. As a result, thickened oil-based cosmetics tend to have a very high viscosity, similar to a solid cream. Consequently, these thickened oil-based cosmetics cannot be impregnated into the sheet. 【0014】 As described above, sheet cosmetics impregnated with an oily liquid composition were found to be highly impractical. 【0015】 Therefore, the inventors conducted diligent research and found that a cosmetic product comprising (A) a sheet containing organically modified clay minerals and (B) a liquid composition containing a surfactant can be realized by contacting the sheet containing (A) the sheet containing organically modified clay minerals with the liquid composition containing (B) the surfactant before use, thereby achieving a cosmetic product with excellent adhesion to the skin and applicable to oily liquid compositions. More specifically, the inventors found that by designing the liquid composition containing (B) the surfactant to have low viscosity before contact with the sheet containing (A) the organically modified clay minerals and to change viscosity to high after contact, a cosmetic product with excellent impregnation into the sheet, excellent adhesion to the skin, and applicable to oily liquid compositions can be realized. 【0016】 <(A) Sheet containing organically modified clay minerals> (A) Sheets containing organically modified clay minerals contain at least organically modified clay minerals and, if necessary, other components. 【0017】 <<Sheet>> (A) As the material of the sheet used for the sheet containing an organically modified clay mineral, there is no particular limitation, and it can be appropriately selected according to the purpose.

Among these, non-woven fabric is preferable in that it can enhance the adhesion of the cosmetic to the skin. 【0018】 As the fibers constituting the non-woven fabric, there is no particular limitation, and it can be appropriately selected according to the purpose. For example, synthetic fibers such as polyethylene terephthalate, polyethylene, polypropylene, etc.; cellulose-based fibers such as cotton, pulp, rayon, cupra, etc. may be mentioned. These may be used alone or in combination of two or more. 【0019】 (A) As the shape, structure, size, and thickness of the sheet used for the sheet containing an organically modified clay mineral, there is no particular limitation, and it can be appropriately selected according to the purpose. 【0020】 For example, it can be made into a shape that follows the shape of the face, such as a shape that follows the shape of a part of the face such as the cheek or the eye area, etc., a shape that matches the shape of the part to be pasted. Also, it is possible to increase the adhesion to the skin by cutting out the parts corresponding to the eyes, nose, and mouth, or making incisions in the parts corresponding to the eyes, nose, and mouth. Note that the timing of processing into the desired shape and size may be after making the sheet containing an organically modified clay mineral, or the sheet may be processed before adding the organically modified clay mineral agent. 【0021】 (A) The sheet used for the sheet containing an organically modified clay mineral may have a single-layer structure or a laminated structure in which a plurality of sheets are stacked.

Examples include components used when bringing a liquid composition containing (B) a surfactant into contact with a sheet containing (A) an organically modified clay mineral (e.g., sprayers, sponges, brushes). Furthermore, when bringing a liquid composition containing (B) a surfactant into contact with a sheet containing (A) an organically modified clay mineral, it is also possible to bring the liquid composition containing (B) a liquid composition containing (B) a liquid composition containing (B) directly into contact with the sheet containing (A) an organically modified clay mineral, without using any special components. 【0074】 There are no particular limitations on the method of bringing the sheet containing (A) organically modified clay minerals into contact with the liquid composition containing (B) surfactant before use, and such method can be appropriately selected depending on the purpose. Examples include applying or spraying the liquid composition containing (B) surfactant onto the sheet containing (A) organically modified clay minerals, or immersing the sheet containing (A) organically modified clay minerals in the liquid composition containing (B) surfactant. (B) When applying or spraying a liquid composition containing a surfactant, (A) the composition may be applied or sprayed before placing the sheet containing the organically modified clay mineral on the application site, or it may be applied or sprayed after placing the sheet. In this disclosure, "before use" means immediately before using the cosmetic product. 【0075】 (A) The amount of the liquid composition containing the surfactant that is brought into contact with the sheet containing the organically modified clay mineral is not particularly limited and can be appropriately selected depending on the purpose, but it is preferably 3 to 20 times, and more preferably 5 to 15 times, the mass of the sheet used with the sheet containing the organically modified clay mineral (the mass of the sheet before the organically modified clay mineral is added). 【0076】 There are no particular restrictions on the area where the sheet is applied, and it can be selected as appropriate depending on the purpose, but it is preferable to apply it to at least a part of the face. 【0077】 According to this disclosure, surprisingly, a gelation reaction occurs simply by bringing a liquid composition containing a surfactant (B) into contact with a sheet containing an organically modified clay mineral (A) and leaving it to stand. Therefore, even when applied to an oily liquid composition, dripping can be suppressed and insufficient adhesion can be resolved. Furthermore, since the gelled liquid composition remains on the application site even after the sheet is peeled off, a sense of satisfaction can be obtained. Accordingly, the cosmetic composition of this disclosure can be suitably used as a cosmetic composition such as a sheet mask for skincare, more preferably for preventing dryness. 【0078】 (kit) A kit according to one embodiment is a cosmetic kit used in which a liquid composition containing a surfactant is brought into contact with a sheet containing an organically modified clay mineral before use, and comprises (A) a sheet containing an organically modified clay mineral and / or (B) a liquid composition containing a surfactant, and optionally includes other components. The kit may contain either (A) a sheet containing an organically modified clay mineral or (B) a liquid composition containing a surfactant, or it may contain both. 【0079】 In this disclosure, "kit" means that each component of the kit exists independently. For example, a kit is not limited to a set consisting of (A) a sheet containing an organically modified clay mineral, (B) a liquid composition containing a surfactant, and other components as needed.

[Examples] 【0086】 The embodiments will be described in more detail below with reference to examples and comparative examples, but the embodiments are not limited to these examples and comparative examples. 【0087】 (Examples 1-10) <(A) Preparation of Sheet> As an example of an organically modified clay mineral, distearyldimonium hectorite (Benton 38V CG, Elements Specialties) was used. As an example of a sheet, nonwoven fabric (nylon nanofiber, Toray Industries, Inc.) was used. 【0088】 <<Coating>> The dimethicone solution contains 29 g / m² of distearyldimonium hectorite in the nonwoven fabric. 2 A coating solution was prepared by dispersing and adjusting it in such a manner. This coating solution was applied to a nonwoven fabric and dried to prepare a sheet containing distearyldimonium hectorite. 【0089】 <(B) Preparation of liquid composition> The liquid compositions (oil-based cosmetics) of Examples 1 to 10 were prepared by mixing each component according to the composition and content (mass%) shown in Tables 1 and 2 below. Furthermore, the viscosity of the liquid compositions prepared under the following measurement conditions was measured using a Type B viscometer (ViscoQC 100L, Anton Paar Japan). -Measurement conditions- Rotor: No.1 Rotation speed: 12 rpm Measurement time: 1 minute Temperature: 25℃ 【0090】 <Rating> A sheet measuring 5.65 cm square was impregnated with 1.25 g of the liquid composition (impregnation ratio: 5 times (relative to the mass of the nonwoven fabric itself)). It was then applied to the skin (face), and after approximately 10 minutes, the adhesion strength was evaluated, and the presence or absence of gel formation was visually confirmed. The evaluation was based on the following criteria. The evaluation was determined by a panel of three experts. ○△, ○, and ◎ represent a range that is practically usable, while ○ and ◎ represent a preferred embodiment. -Evaluation Criteria- ◎: It forms a gel and feels very strong in its adhesion to the skin. ○: It forms a gel and feels very close to the skin. ○△: It forms a gel and feels like it adheres well to the skin. △: There is slight gel formation, but the adhesion to the skin is low. ×: No gel is formed, and it does not adhere to the skin. 【0091】 [Table 1] 【0092】 [Table 2] 【0093】 As shown in Tables 1 and 2, it was confirmed that in Examples 1 to 10, cosmetics with high adhesive strength and excellent adhesion to the skin could be produced. It was also confirmed that using two or more surfactants in combination increased adhesive strength even with a small amount of surfactant. 【0094】 (Comparative Examples 1-3) <(A) Preparation of Sheet> The same nonwoven fabric as in Examples 1-10 was used as the sheet, except that it did not contain organically modified clay minerals. 【0095】 <(B) Preparation of liquid composition> Each component was mixed according to the composition and content (mass%) shown in Table 3 below to prepare the liquid compositions (oil-based cosmetics) of Comparative Examples 1 to 3. Furthermore, the viscosity of the prepared liquid compositions was measured in the same manner as in Examples 1 to 10. 【0096】 <Rating> In the same manner as in Examples 1 to 10, 1.25 g of the liquid composition was impregnated into the sheet (impregnation ratio: 5 times), and the evaluation was performed. 【0097】 [Table 3] 【0098】 As shown in Table 3, in Comparative Examples 1-3, where the sheet did not contain organically modified clay minerals, adhesive strength was not achieved, and it was not possible to create a cosmetic product that adhered to the skin. 【0099】 (Examples 11-14, Comparative Example 4) <(A) Preparation of Sheet> The distearyldimonium hectorite content in the nonwoven fabric is 60 g / m². 2 Except as otherwise stated, sheets containing organically modified clay minerals were prepared in the same manner as in Procedures 1 to 10. 【0100】 <(B) Preparation of liquid composition> The liquid compositions (oil-based cosmetics) of Examples 11-14 and Comparative Example 4 were prepared by mixing each component according to the composition and content (mass%) shown in Table 4 below. Furthermore, the viscosity of the prepared liquid compositions was measured in the same manner as in Examples 1 to 10. 【0101】 <Rating> The evaluation was carried out in the same manner as in Examples 1 to 10, except that 1.5 g of the liquid composition was impregnated into the sheet (impregnation ratio: 6 times (relative to the mass of the nonwoven fabric itself)). 【0102】 [Table 4] 【0103】 As shown in Table 4, it was confirmed that even when the content of organically modified clay minerals in the sheet was changed, it was possible to create a cosmetic with high adhesive strength and excellent adhesion to the skin. It was also confirmed that even when using a sheet containing organically modified clay minerals, if the liquid composition does not contain a surfactant, it will not exhibit adhesive strength and cannot be made into a cosmetic with good adhesion. 【0104】 The details of each component used in the liquid composition (B) of the above examples and comparative examples are as follows.
