Description

Technical Field

[0001] This invention relates to cosmetics, kits, and liquid compositions. Background Technology

[0002] Previously, cosmetics such as two-component sheet masks, which are applied to the face after contacting a sheet made of non-woven fabric or similar material with a liquid cosmetic composition, were widely used. These cosmetics achieve significant cosmetic effects such as firming and skin care by covering the face with a sheet soaked in a liquid cosmetic composition for a certain period of time.

[0003] To date, dry-type masks are easy to apply and have excellent adhesion to the skin. They remain soft even when dry, adhere well to the skin, and are not prone to lifting off the skin. They also easily provide the effects of moisturizing and hydrating. As a technology to provide such sheet-like cosmetic masks, a cosmetic mask has been proposed, which consists of a dry sheet-like nonwoven fabric mask with a specific water-soluble polymer supported by a nonwoven fabric and a lotion containing specific ingredients. When applying the mask, the nonwoven fabric mask is moistened and softened with the lotion (see Patent Document 1).

[0006] [Patent Document 1] Japanese Patent Application Publication No. 2016-155764 Summary of the Invention

[0007] [The problem the invention aims to solve]

[0008] However, the current technology does not provide sufficient skin adhesion and there is still room for improvement.

[0009] In addition, in recent years, a type of oil-based cosmetic, namely oil-based beauty serum, has become quite popular in the market. However, sheet cosmetics soaked in oil-based beauty serum have not yet entered the market. It is speculated that this is because oil-based beauty serums, which are skin-friendly and feel good, have low surface tension and low viscosity, thus causing "liquid residue" when soaking sheet materials, and the sheet materials do not adhere closely to the skin.

[0010] In view of the above, one objective of the present invention is to provide a cosmetic that has excellent adhesion to the skin and is also applicable to oily liquid compositions.

[0011] [Methods for solving the problem]

[0012] To address the aforementioned issues, one aspect of the cosmetic product of the present invention comprises (A) a sheet containing an organically modified clay mineral and (B) a liquid composition containing a surfactant, wherein, prior to use, the (A) sheet containing the organically modified clay mineral is contacted with the (B) liquid composition containing the surfactant.

[0013] [The effects of the invention]

[0014] According to one aspect of the present invention, a cosmetic product can be provided that has excellent adhesion to the skin and is also suitable for oily liquid compositions. Detailed Implementation

[0015] Hereinafter, embodiments of the present invention will be described in detail. Furthermore, the embodiments are not limited to those described below, and appropriate modifications may be made without departing from the spirit of the present invention. Additionally, in this specification, the term "~" indicating a numerical range, unless otherwise specified, means that the values ​​described before and after it are included as a lower limit and an upper limit.

[0016] (cosmetic)

[0017] One embodiment of the cosmetic comprises (A) a sheet containing an organically modified clay mineral and (B) a liquid composition containing a surfactant, and may also contain other components as needed. Prior to use, the cosmetic comprises (A) the sheet containing the organically modified clay mineral and (B) the liquid composition containing the surfactant.

[0018] As mentioned above, sheet cosmetics made by impregnating sheets with oil-based beauty solutions have not yet entered the market. This is presumably because oil-based beauty solutions, which are skin-friendly and have a good feel, have low surface tension and low viscosity, resulting in "liquid residue" when impregnating sheets, and the sheets do not adhere closely to the skin.

[0019] Furthermore, it is very difficult to moderately thicken oil-based cosmetics. Therefore, thickened oil-based cosmetics are typically solid creams with very high viscosity. As a result, thickened oil-based cosmetics cannot impregnate sheets.

[0020] As mentioned above, the feasibility of sheet cosmetics made by impregnating sheet materials with oily liquid compositions is very low.

[0021] Therefore, through careful research, the inventors discovered that a cosmetic product containing (A) a sheet comprising an organically modified clay mineral and (B) a liquid composition comprising a surfactant, wherein the sheet comprising (A) the organically modified clay mineral is brought into contact with the liquid composition comprising (B) the surfactant before use, can achieve excellent skin adhesion and is also suitable for oily liquid compositions. More specifically, it was discovered that by designing a change in viscosity from low before contact between the liquid composition comprising (B) the surfactant and the sheet comprising (A) the organically modified clay mineral, and high after contact, a cosmetic product can achieve excellent sheet impregnation, excellent skin adhesion, and is also suitable for oily liquid compositions.

[0022] <(A) Sheets containing organically modified clay minerals>

[0023] (A) Sheets containing organically modified clay minerals contain at least organically modified clay minerals and may contain other ingredients as needed.

[0028] For example, the shape can be designed to fit the face shape, the cheek, the area around the eyes, or other parts of the face. Furthermore, cutting out sections corresponding to the eyes, nose, and mouth, and making incisions in those sections, can improve the adhesion to the skin.

[0029] Furthermore, the processing of the sheet into the desired shape and size can be done either after it has been made into a sheet containing organically modified clay minerals, or before it has been made into a sheet containing organically modified clay minerals.

[0030] The sheet used for (A) the sheet containing organically modified clay minerals can be a single-layer structure or a multi-layered structure. In the case of a multi-layered structure, the sheets can be made of the same material or different materials.

[0138] (Examples 1-10)

[0139] <(A) Sheet Preparation>

[0140] As an example of an organically modified clay mineral, distearate dimethylammonium hydropyroxene (BENTONE 38V CG, Elementis Specialties) was used. Additionally, as an example of a sheet material, nonwoven fabric (nylon nanofibers, Toray Industries, Inc.) was used.

[0141] <<Coating>>

[0142] In a polydimethylsiloxane solution, the content of distearate dimethylammonium pyroxene in the nonwoven fabric was increased to 29 g / m³. 2 Then, the mixture is dispersed and adjusted to prepare the coating solution.

[0143] The coating solution is applied to a nonwoven fabric and dried to prepare a sheet containing distearate dimethylammonium hydropyrite.

[0144] <(B) Formulation of Liquid Compositions>

[0145] The liquid compositions (oil-based cosmetics) of Examples 1 to 10 were prepared by mixing the components with the composition and content (mass %) shown in Tables 1 and 2 below.

[0146] In addition, the viscosity of the prepared liquid composition was measured using a Type B viscometer (ViscoQC 100L, Anton Paar Japan) under the following test conditions.

[0147] -Determination Conditions-

[0148] Rotor: No.1

[0149] Rotation speed: 12 rpm

[0150] Measurement time: 1 minute

[0151] Temperature: 25℃

[0152] <Evaluation>

[0153] Impregnate a 5.65cm square sheet with 1.25g of the liquid composition (impregnation ratio: 5 times (relative to the mass of the nonwoven fabric itself)). Then apply it to the skin (face), and evaluate the adhesion after approximately 10 minutes by visually confirming the presence or absence of gel formation, based on the evaluation criteria below. The evaluation is determined by a specialized panel of 3 people. Furthermore, ○△, ○, and ◎ represent the applicable range, with ○ and ◎ being the preferred methods.

[0154] -Evaluation Criteria-

[0155] ◎: It forms a gel and feels very close to the skin.

[0156] ○: It forms a gel and feels very close to the skin.

[0157] ○△: Gel forms, giving a feeling of close adherence to the skin.

[0158] △: Slight gel formation, low adhesion to the skin.

[0159] ×: No gel formation, no skin adhesion.

[0160] Table 1

[0161]

[0162] Table 2

[0163]

[0164] As shown in Tables 1 and 2, it can be confirmed that cosmetics with high adhesion and excellent skin adhesion can be obtained in Examples 1 to 10. It was also confirmed that the adhesion can be improved even with a small amount of surfactant when two or more surfactants are used in combination.

[0165] (Comparative Examples 1-3)

[0166] <(A) Sheet Preparation>

[0167] As a sheet material, the same nonwoven fabric as in Examples 1-10 is used, except that it does not contain organically modified clay minerals.
