Description

【Technical Field】 【0001】 The present disclosure relates to cosmetics, kits, and liquid compositions. 【Background Art】 【0002】 Conventionally, immediately before use, a two-part cosmetic such as a sheet mask is widely and commonly used, in which a liquid cosmetic composition is brought into contact with a sheet such as a non-woven fabric and then affixed to the face or the like. This cosmetic attempts to obtain high cosmetic effects such as lifting and skin care by covering the face or the like with a sheet impregnated with a liquid cosmetic composition for a certain period of time. 【0003】 So far, as a technology for providing a sheet-like cosmetic pack that is easy to handle in a dry type, has excellent adhesiveness to the skin, remains soft even after drying, has excellent adhesiveness and is difficult to lift from the skin, and is likely to exhibit a pack effect such as a heat retention effect and a moisturizing effect, a cosmetic pack has been proposed that consists of a dry sheet-like non-woven fabric mask in which a specific water-soluble polymer is supported on a non-woven fabric and a lotion containing specific components, and the non-woven fabric mask is moistened and softened with the lotion when packing (see Patent Document 1). 【Prior Art Documents】 【Patent Documents】 【0004】 【Patent Document 1】 Japanese Patent Application Laid-Open No. 2016-155764 【Summary of the Invention】 【Problems to be Solved by the Invention】 【0005】 However, in the conventional technology, the adhesiveness to the skin is not sufficient, and there is room for further improvement. 【0006】 In view of the above, one aspect of the present disclosure aims to provide a cosmetic having excellent adhesion to the skin. 【Means for Solving the Problems】 【0007】 To solve the above problems, one embodiment of the cosmetic composition according to the present disclosure comprises (A) a sheet containing an associative thickener and (B) a liquid composition, wherein the liquid composition (B) is brought into contact with the sheet containing the associative thickener (A) before use. [Effects of the Invention] 【0008】 According to one aspect of this disclosure, it is possible to provide a cosmetic product that has excellent adhesion to the skin. [Modes for carrying out the invention] 【0009】 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. 【0010】 (Cosmetics) A cosmetic composition according to one embodiment comprises (A) a sheet containing an associative thickener and (B) a liquid composition, and optionally includes other components. Before use, the cosmetic composition according to one embodiment is brought into contact with (B) the liquid composition on (A) the sheet containing the associative thickener. 【0011】 For example, a sheet mask designed for lifting requires the sheet, such as a non-woven fabric, to lift the skin and maintain that lifted position. At the same time, the sheet mask is expected to be impregnated with a moist cosmetic product, such as a serum. Therefore, the cosmetic product must be flexible, adhere to the skin, and maintain its shape with strong adhesion. 【0012】 Conventional lifting sheet masks, for example, have a structure that hooks over the ears to physically secure them and enhance adhesion. However, this presents the problem of putting strain on the ears. In addition, because the sheet is impregnated with cosmetics such as serum to become moist, there is the problem of resistance to the sheet coming into contact with the back of the ears or hair. 【0013】 Another method involves using highly stretchable nonwoven fabric for the sheet to lift the skin, but this method has the drawback of weak adhesion and poor fixation. 【0014】 On the other hand, it is also possible to improve adhesion to the skin by giving the liquid impregnated into the sheet mask high adhesion properties. In this case, it is possible to incorporate ingredients with adhesive properties, but in order to exhibit adhesiveness, it is necessary to have a relatively low water content, like a gel-like substance such as a poultice or tape. Another approach is to incorporate a large amount of thickener, but in that case, the viscosity of the liquid impregnating the sheet mask becomes high, resulting in poor impregnation efficiency and difficulty in uniformly impregnating the sheet. 【0015】 Therefore, the inventors conducted diligent research and found that a cosmetic product comprising (A) a sheet containing an associative thickener and (B) a liquid composition can be realized by bringing the (B) liquid composition into contact with the (A) sheet containing the associative thickener before use, thereby achieving a cosmetic product with excellent adhesion to the skin. More specifically, they found that by designing the (B) liquid composition to have low viscosity before contact with the (A) sheet containing the associative thickener and to change to high viscosity after contact, a cosmetic product with excellent impregnation into the sheet and excellent adhesion to the skin can be realized. 【0016】 <(A) Sheet containing an associative thickener> (A) A sheet containing an associative thickener contains at least an associative thickener and, if necessary, other components. 【0017】 <<Sheet>> (A) The sheet used for the sheet containing the associative thickener is not particularly limited and can be appropriately selected according to the purpose. However, in terms of being able to further enhance the adhesion of the cosmetic to the skin, it is preferably one with low extensibility. For example, when the sheet is pasted while being pulled up along the face line, by using a sheet with low extensibility, it is possible to suppress the stretched sheet from stretching and returning to its original state during use. Also, because the adhesion is very strong, it can be fixed in a stretched state. Therefore, excellent adhesion can be obtained even without making the structure of the sheet a structure that fits over the ear. 【0018】 (A) The elongation rate of the sheet used for the sheet containing the associative thickener is not particularly limited and can be appropriately selected according to the purpose. However, when a tensile test is performed at a speed of 10 mm / min for 3 minutes, the elongation rate (length in the stretching direction after the tensile test / length in the stretching direction before the tensile test × 100) is preferably less than 120%, more preferably less than 110%, and particularly preferably less than 105%. 【0019】 In the present disclosure, the stretching direction (tensile direction) in the tensile test refers to the direction in which the sheet stretches the most when the sheet is pulled. For example, when a non-woven fabric is used as the sheet, the direction parallel to the fiber length direction is the stretching direction. 【0020】 Note that the tensile test is performed on the sheet itself (the sheet before adding the associative thickener). Also, for the tensile test, a sheet in a dry state (water content of 10 mass% or less) is used. 【0021】 The apparatus used for the tensile test is not particularly limited, and a known apparatus can be appropriately selected. For example, FUDOH Rheometer RTC (manufactured by Rheotech Co., Ltd.) and the like can be mentioned. 【0022】 (A) The material of the sheet used for the sheet containing the associative thickener is not particularly limited and can be appropriately selected according to the purpose. For example, non-woven fabrics, woven fabrics, paper, water-containing gel sheets, and the like can be mentioned. Among these, non-woven fabrics are preferred in terms of being able to further enhance the adhesion of the cosmetic to the skin. 【0023】 The fibers constituting the non-woven fabric are not particularly limited and can be appropriately selected according to the purpose. For example, synthetic fibers such as polyethylene terephthalate, polyethylene, and polypropylene; cellulose-based fibers such as cotton, pulp, rayon, and cupra can be mentioned. These may be used alone or in combination of two or more. 【0024】 (A) The shape, structure, size, and thickness of the sheet used for the sheet containing the associative thickener are not particularly limited and can be appropriately selected according to the purpose. 【0025】 For example, it can be made into a shape following the shape of the face, such as a shape following the shape of a part of the face like the cheek or the area around the eyes, etc., a shape adapted to the shape of the part to be pasted. Also, the adhesion to the skin can be improved 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 the associative thickener, or the sheet may be processed before adding the associative thickener. 【0026】 (A) The sheet used for the sheet containing the associative thickener may have a single-layer structure or a laminated structure with multiple sheets stacked. In the case of a laminated structure, the materials of the sheets of each layer may be the same or different. 【0027】 (A) The basis weight of the sheet used for the sheet containing the associative thickener is not particularly limited and can be appropriately selected according to the purpose. 【0028】 (A) Commercially available products may be used for the sheet used for the sheet containing the associative thickener, or those manufactured by known methods may be used. 【0029】 <<Associative thickener>> An "associative thickener" is a copolymer having a hydrophilic portion made of a water-soluble monomer and a hydrophobic portion made of a hydrophobic monomer, which acts as a macromolecule that is physically cross-linked by associating through hydrophobic interactions in an aqueous solvent, thereby thickening the system (see, for example, paragraph 0014 of Japanese Patent Publication No. 2000-239120). 【0030】 There are no particular restrictions on the associative thickener, and it can be appropriately selected depending on the purpose, but hydrophobic modified polyether urethanes are preferred, and compounds represented by the following general formula (1) are more preferred. [ka] However, in the general formula (1) above, R represents a hydrophobic portion, X represents a hydrophilic portion obtained by addition polymerization of an alkylene oxide containing ethylene oxide to an organic compound having at least two active hydrogen groups, B represents a bonding portion containing an ether group or an ester group, and n represents an integer from 1 to 5. 【0031】 Among these, copolymers with a mass ratio of hydrophilic portion to hydrophobic portion [hydrophilic portion:hydrophobic portion] of 5:1 to 1,000:1 are preferred as associative thickeners, copolymers in which the hydrophilic portion X is polyethylene oxide are more preferred, and copolymers in which the hydrophobic portion R is a monovalent hydrocarbon group having 6 or more carbon atoms or a monovalent fluorinated carbon group having 4 or more carbon atoms, and the hydrophilic portion of the copolymer is polyethylene oxide in units of 30 to 6,000 (integers), are particularly preferred. 【0032】 Among these, the hydrophobic modified polyether urethane represented by the general formula (1) is particularly preferred if its INCI name is "(PEG-240 / Decyltetradeceth-20 / HDI) Copolymer (PEG-240 / HDI Copolymer Bis-Decyltetradeceth-20 Ether)". "HDI" is an abbreviation for hexamethylene diisocyanate. 【0033】 The hydrophobic modified polyether urethane represented by general formula (1) may be synthesized as appropriate by known methods, or a commercially available product may be used. Examples of commercially available hydrophobic modified polyether urethanes represented by general formula (1) include Adekanol GT-700 ((PEG-240 / decyltetradeceth-20 / HDI) copolymer) and Adekanol GT-730 ((PEG-240 / decyltetradeceth-20 / HDI) copolymer) (both from ADEKA Corporation). 【0034】 (A) There are no particular restrictions on the content of the associative thickener in a sheet containing the associative thickener, and it can be appropriately selected depending on the purpose, but 1 to 20 g / m² 2 Preferably, 2-15 g / m 2 More preferably, 3-12 g / m 2 This is particularly preferable. Being within the aforementioned preferred range is advantageous because it allows for greater adhesion of the cosmetic product to the skin. 【0035】 <<Other components in the sheet>> (A) Other components in the sheet containing the associative thickener are not particularly limited as long as they do not impair the effects of the present disclosure, and known components used in cosmetics can be appropriately selected. (A) Other components in the sheet containing the associative thickener may be used alone or in combination of two or more.

However, a preferred method is to prepare a solution by dissolving the associative thickener in a solvent, bring the solution into contact with the sheet, and then dry it. By first dissolving the associative thickener and then drying it, (B) a cosmetic can be made that swells rapidly and forms a gel network simply by coming into contact with a liquid composition. 【0037】 There are no particular restrictions on the solvent used to dissolve the associative thickener; it can be appropriately selected depending on the purpose, and examples include water and alcohol. 【0038】 There are no particular restrictions on the concentration of the associative thickener in the solution; it can be appropriately selected depending on the amount to be included in the sheet. 【0039】 The solution may contain other components besides the associative thickener. Examples of such other components include dipropylene glycol. 【0040】 There are no particular restrictions on the method of bringing the solution into contact with the sheet; known methods can be appropriately selected, such as coating, spraying, or immersion. These methods may be used individually or in combination of two or more. 【0041】 There are no particular restrictions on the drying method, and any known method can be appropriately selected, such as heating drying or forced-air drying. These methods may be used individually or in combination of two or more. 【0042】 (B) The sheet containing (A) the associative thickener before contact with the liquid composition is preferably in a dry state. Being in a dry state means that the water content is 10% by mass or less. 【0043】 <(B) Liquid composition> (B) The liquid composition is a composition that is brought into contact with the sheet containing (A) the associative thickener, and may also be referred to as a liquid cosmetic composition (cosmetic liquid, lotion, beauty serum, etc.). (B) The liquid composition may contain known ingredients used in cosmetics as appropriate. 【0044】 Known ingredients used in cosmetics include, for example, thickeners; moisturizing ingredients, sebum-absorbing ingredients, active ingredients such as pharmaceuticals; surfactants; oils; water; alcohol; buffering agents; chelating agents; preservatives; polymers; powders; neutralizing agents; stabilizers; and fragrances.

In this disclosure, "before use" means immediately before using the cosmetic product. 【0078】 (A) The amount of (B) liquid composition to be brought into contact with the sheet containing the associative thickener is not particularly limited and can be appropriately selected depending on the purpose, but is preferably 3 to 20 times, and more preferably 5 to 15 times, the mass of the sheet used for the sheet containing the associative thickener (the mass of the sheet before the associative thickener is added). 【0079】 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. 【0080】 According to this disclosure, by bringing a liquid composition (B) into contact with a sheet containing an associative thickener (A), the associative thickener swells rapidly, forming a gel network between the skin to which the sheet is applied and the sheet, resulting in high adhesion. Therefore, an excellent skin-lifting effect (improved lifting effect) can be expected, and it can be suitably used as a cosmetic such as a sheet mask for skincare, and more preferably for lifting. 【0081】 (kit) A kit according to one embodiment is a cosmetic kit used in which a liquid composition is brought into contact with a sheet containing an associative thickener before use, and comprises (A) a sheet containing an associative thickener and / or (B) a liquid composition, and optionally includes other components. The kit may include either (A) a sheet containing an associative thickener or (B) a liquid composition, or it may include both. 【0082】 In this disclosure, "kit" means that each component of the kit exists independently. For example, a kit is not limited to a set comprising (A) a sheet containing an associative thickener, (B) a liquid composition, and other components as needed.

For example, they could include an explanation of the contents of this disclosure as described above. 【0087】 (Liquid composition) One embodiment of the liquid composition is used by bringing it into contact with a sheet containing an associative thickener before use. 【0088】 The liquid composition is the same as the liquid composition (B) described in the (cosmetics) section above. [Examples] 【0089】 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. 【0090】 (Examples 1-10, Comparative Examples 1-6) <(A) Preparation of Sheet> As an example of a sheet, nonwoven fabric A (CQT-70, Daiwa Spinning Co., Ltd.) or nonwoven fabric B (nylon nanofiber, Toray Industries, Inc.) was used. 【0091】 <<Sheet stretch ratio>> The elongation rates of nonwoven fabrics A and B were measured as follows. The nonwoven fabric strips, while dry (before the coating process described later), were cut into strips measuring 3 cm x 10 cm. The strips were cut so that the longer side (10 cm) was parallel to the length of the fibers. The top and bottom 2.5 cm of the long side of the cut nonwoven fabric piece were clamped with a rheometer (FUDOH Rheometer RTC, Rheotec Co., Ltd.) and fixed in a position where there was no slack. A tensile test was performed at a speed of 10 mm / min for 3 minutes, and the length of the test piece was measured after the test. 【0092】 The measurement results showed that the length of the test specimens after testing was 15.3 cm for nonwoven fabric A and 10.4 cm for nonwoven fabric B (both were average values ​​from three tests). Therefore, the elongation rate was 153% for nonwoven fabric A and 104% for nonwoven fabric B, confirming that nonwoven fabric A is a nonwoven fabric with good elongation and nonwoven fabric B is a nonwoven fabric with poor elongation. Furthermore, when the nonwoven fabric was cut so that the longer side was perpendicular to the length direction of the fibers, and the same tensile test was performed, there was almost no difference in length between nonwoven fabrics A and B before and after the test. 【0093】 <<Coating>> A coating solution (see below for formulation) was prepared by adjusting the amount of the components listed in Tables 1-3 so that their content in nonwoven fabric A or B was as indicated in Tables 1-3. Specifically, the amount of the components required for the nonwoven fabric to be processed was calculated from the weight per unit area and dissolved in a solution of water and dipropylene glycol (DPG). This solution was applied to a nonwoven fabric and dried to prepare a sheet containing the components listed in Tables 1-3. -Coating solution formulation- • Alcohol 30% by mass · DPG 5% by mass • Ingredients (Adjusted to the amounts listed in Tables 1-3) • Deionized water remaining amount Total 100% by mass 【0094】 The details of the ingredients contained in the sheet are as follows: • Associative thickener: (PEG-240 / decyltetradeceth-20 / HDI) copolymer (Adekanol GT-700, ADEKA Corporation) • Polysaccharides: Xanthan gum (Celtrol, CP Kelco) • Electrostatic repulsive thickener: (Dimethylacrylamide / Sodium acryloyldimethyl taurate) crosspolymer (SU-GEL, Toho Chemical Co., Ltd.) 【0095】 <(B) Preparation of liquid composition> The liquid compositions (aqueous cosmetics) of Examples 1 to 10 and Comparative Examples 1 to 6 were prepared by mixing each component according to the composition and content (mass%) shown in Tables 1 to 3 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℃ 【0096】 The details of the thickener used in the liquid composition (B) of the above examples and comparative examples are as follows. [Thickener] • (PEG-240 / Decyltetradeceth-20 / HDI) Copolymer (Adekanol GT-700, ADEKA Corporation) • Xanthan gum (Celtrol, CP Kelco) • Carbomer (Carbopol 981, Lubrizol) 【0097】 <Rating> For evaluation, sheets cut into the shape of a face were used. Immediately before evaluation, the sheet was impregnated with a liquid composition to a ratio eight times its weight (impregnation ratio: 8 times). Then, without delay, the sheet was applied to the face, and its adhesion was evaluated based on the following evaluation criteria. The evaluation was determined by a panel of three experts. -Evaluation Criteria- A: I feel that it adheres very strongly. B: I feel it has strong adhesion. C: I don't feel it adheres very well. D: I feel the adhesion is weak. 【0098】 [Table 1] 【0099】 [Table 2] 【0100】 [Table 3] 【0101】 As shown in Tables 1-3, it was confirmed that including an associative thickener in the sheet increases the adhesion of the cosmetic to the skin. Furthermore, it was confirmed that including an associative thickener in the liquid composition further enhances adhesion to the skin. Moreover, the effect of improving adhesion was confirmed even in sheets that are not easily stretched. 【0102】 Examples of the types of disclosures include the following: <1> (A) A sheet containing an associative thickener, (B) A liquid composition comprising, This cosmetic involves bringing the liquid composition (B) into contact with the sheet containing the associative thickener (A) before use. <2> The (B) liquid composition contains an associative thickener, <1> It is a cosmetic product as described above. <3> The concentration of the associative thickener in the liquid composition (B) is 0.1 to 1.0% by mass, <2> It is a cosmetic product as described above. <4> The associated thickener is a hydrophobic modified polyether urethane, <1> from <3> It is a cosmetic product as described in any of the following. <5> The content of the associated thickener in the sheet containing the associated thickener described in (A) above is 1 to 20 g / m². 2 The above <1> from <4> It is a cosmetic product as described in any of the following. <6> The sheet used in the sheet containing the (A) associative thickener has an elongation rate (length in the elongated direction after the tensile test / length in the elongated direction before the tensile test × 100) of less than 120% when subjected to a tensile test at a speed of 10 mm / min for 3 minutes. <1> from <5> It is a cosmetic product as described in any of the following. <7> The sheet used in the sheet containing the (A) associative thickener is a nonwoven fabric, <1> from <6> It is a cosmetic product as described in any of the following. <8> The viscosity of the liquid composition (B) is 1,000 mPa·s or less, <1> from <7> It is a cosmetic product as described in any of the following. <9> The above (B) liquid composition is an aqueous cosmetic, <1> from <8> It is a cosmetic product as described in any of the following. <10> A kit for use in cosmetics, which involves contacting a liquid composition with a sheet containing an associative thickener before use, The kit comprises (A) a sheet containing an associative thickener and / or (B) a liquid composition. <11> The (B) liquid composition contains an associative thickener, <10> This is the kit described in [the document / page]. <12> The concentration of the associative thickener in the liquid composition (B) is 0.1 to 1.0% by mass, <11> This is the kit described in [the document / page]. <13> The associated thickener is a hydrophobic modified polyether urethane, <10> from <12> It is a kit as described in one of the following. <14> The content of the associated thickener in the sheet containing the associated thickener described in (A) above is 1 to 20 g / m². 2The above <10> from <13> It is a kit as described in one of the following. <15> The sheet used in the sheet containing the (A) associative thickener has an elongation rate (length in the elongated direction after the tensile test / length in the elongated direction before the tensile test × 100) of less than 120% when subjected to a tensile test at a speed of 10 mm / min for 3 minutes. <10> from <14> It is a kit as described in one of the following. <16> The sheet used in the sheet containing the (A) associative thickener is a nonwoven fabric, <10> from <15> It is a kit as described in one of the following. <17> The viscosity of the liquid composition (B) is 1,000 mPa·s or less, <10> from <16> It is a kit as described in one of the following. <18> The above (B) liquid composition is an aqueous cosmetic, <10> from <17> It is a kit as described in one of the following. <19> This is a liquid composition that is used by bringing it into contact with a sheet containing an associative thickener before use. 【0103】 As described above, this disclosure has been explained based on specific embodiments and examples, but these embodiments and examples are merely presented as examples, and this disclosure is not limited to the above embodiments and examples.
