Description

[Technical Field]

[0001] The present invention relates to an aqueous cosmetic preparation. [Background technology]

[0002] Among conventional water-based eye makeup cosmetics, eyeliners and eyebrow pencils containing glittering pigments are popular because of their effect of making the eyes look more vibrant. Generally, many of these cosmetics aim to create a highly luminous coating by incorporating a large amount of glittering pigment and a large amount of thickener to prevent the glittering pigment from settling. Cosmetics containing large amounts of glittering pigment and thickener are highly viscous and cannot be consistently dispensed from automatic brush pen containers that naturally dispense cosmetics. Therefore, they are typically used in mechanical pen-type containers equipped with a knock or dial to forcibly dispense the cosmetics (Patent Document 1). However, application is time-consuming and adjusting the amount of liquid is difficult, making them difficult to use for beginners.

[0003] On the other hand, an eyeliner cosmetic that can be continuously applied without clogging even in a cotton-filled brush pen container has been reported, for example, to contain carbon black as a pigment and silver-coated glass flakes as a glitter pigment (Patent Document 2). However, the glitter pigments that can be used with this cosmetic are limited, and it is not possible to accommodate a variety of color tones.

[0004] To solve the above problems, the present inventors have succeeded in developing a water-based eye makeup cosmetic that has high brightness similar to that of mechanical eyeliner cosmetic products and can be used with a pen-type container that discharges glitter naturally (Patent Document 3). However, this cosmetic product was not sufficient in terms of the stability of the discharge of glitter on the drawn line and its stability over time in a high-temperature environment.

[0005] [Patent Document 1] Patent No. 5430149 [Patent Document 2] Japanese Patent Application Laid-Open No. 2016-041674 [Patent Document 3] Japanese Patent Publication No. 2022-131500 Summary of the Invention [Problem to be solved by the invention]

[0006] An object of the present invention is to provide a water-based eye makeup cosmetic for use in a natural discharge container, which has improved discharge of a glitter pigment and improved stability over time. [Means for solving the problem]

[0007] As a result of extensive research, the inventors have discovered that by combining a specific glitter pigment, a coating agent, and a thickener, it is possible to stably eject glitter, prevent the applied lines from bleeding, and further improve stability over time.

[0008] Specifically, the present invention provides an aqueous cosmetic comprising the following components: (a) a brilliant pigment, (b) an acrylic resin emulsion, and (c) a thickener selected from the group consisting of cellulose gum, hydroxypropyl methylcellulose, and hydroxyethyl cellulose, wherein component (a) comprises (a1) an aluminum-based brilliant pigment having an average particle size of 10 to 150 μm, and the content of component (a) in the aqueous cosmetic is 1 to 20 mass%, the content of component (a1) is 0.1 to 20 mass%, the content of component (b) is 1 to 10 mass%, calculated as solids content, and the content of component (c) is 0.01 to 1 mass%.

[0009] The average particle size of the component (a1) is preferably 15 to 80 μm.

[0010] The component (a) preferably further contains (a2) a bright pigment based on glass or resin and having an average particle size of 10 to 150 μm.

[0011] In the aqueous cosmetic preparation, the content of component (a1) is preferably 0.3 to 14.5% by mass, and the content of component (a2) is preferably 0.5 to 14.7% by mass.

[0012] The aqueous cosmetic preferably further contains (d) an anionic or nonionic acrylic polymer.

[0013] The aqueous cosmetic preferably further contains (e) bentonite. [Effects of the Invention]

[0014] According to the present invention, it is possible to provide a water-based eye makeup cosmetic for a spontaneous discharge container that has high stability and ease of use. DETAILED DESCRIPTION OF THE INVENTION

[0015] The present invention will be described in detail below, but the present invention is not limited to the embodiments described in this specification.

[0016] The present invention is an aqueous cosmetic comprising the following components: (a) a brilliant pigment, (b) an acrylic resin emulsion, and (c) a thickener selected from the group consisting of cellulose gum, hydroxypropyl methylcellulose, and hydroxyethyl cellulose, wherein component (a) comprises (a1) an aluminum-based brilliant pigment having an average particle size of 10 to 150 μm, and the content of component (a) in the aqueous cosmetic is 1 to 20 mass%, the content of component (a1) is 0.1 to 20 mass%, the content of component (b) is 1 to 10 mass%, calculated as solids content, and the content of component (c) is 0.01 to 1 mass%.

[0017] The bright pigment component (a) of the present invention includes an aluminum-based bright pigment (a1) having an average particle size of 10 to 150 μm. If the average particle size of the bright pigment (a1) is less than 10 μm, sufficient brightness cannot be obtained. If it exceeds 150 μm, clogging may occur in a direct-fill or cotton-filled brush pen container, leading to poor discharge. To further improve brightness and discharge stability, the average particle size is preferably 20 to 130 μm, and more preferably 20 to 120 μm. Here, the "average particle size" refers to a value determined, for example, by measurement using a particle size distribution analyzer based on the laser diffraction / scattering method or observation using an ultra-high-voltage transmission electron microscope (TEM) or scanning electron microscope (SEM). When using a commercially available product, the average particle size indicated on the product may be used.

[0018] The bright pigment (a1) of the present invention has the above average particle size and is based on aluminum. Specifically, it may be, for example, aluminum flakes coated with silica or metal nanoparticles. The bright pigment (a1) of the present invention can be used alone or in combination of two or more types selected arbitrarily.

[0019] The bright pigment (a1) that can be used in the present invention is commercially available, and commercially available products can also be used. Preferred commercially available products include Cosmicolor Metallics Forest Silver (average particle size: 20 μm), Cosmicolor Metallics Crystal Silver (average particle size: 64 μm), Cosmicolor Metallics Velvet Silver (average particle size: 13 μm), Cosmicolor Celeste series (average particle size: 20 μm), and Cosmicolor Stratone series (average particle size: 20 μm) (all from Toyo Aluminum).

[0020] The content of the glittering pigment (a) in the aqueous cosmetic of the present invention is 1 to 20% by mass, and the content of the glittering pigment (a1) is 0.1 to 20% by mass, when the total mass of the aqueous cosmetic is taken as 100%. Within these ranges, both good cosmetic effects and stable ejection can be achieved. On the other hand, if the content of the glittering pigment (a) is less than 0.1% by mass, a sufficient glitter effect (dotted effect) cannot be obtained, and if the content of the glittering pigment (a) is more than 20% by mass, the glittering pigment clogs the flow path, resulting in ejection failure. Furthermore, if the content of the glittering pigment (a1) is less than 0.1% by mass, a sufficient glitter effect cannot be obtained, and the metallic effect (glossiness) is also reduced. The content of the glittering pigment (a) in the aqueous cosmetic of the present invention is preferably 5 to 15 mass%, particularly preferably 3 to 10 mass%, and the content of the glittering pigment (a1) is preferably 0.3 to 14.5 mass%, particularly preferably 0.5 to 9.0 mass%.

[0021] The brilliant pigment (a) in the aqueous cosmetic of the present invention preferably further comprises, in addition to the brilliant pigment (a1), a brilliant pigment (a2) based on glass or resin and having an average particle size of 10 to 150 μm. Specific examples of the brilliant pigment (a2) in the present invention include, but are not limited to, borosilicate (Ca / Al), borosilicate (Ca / Na), (PET / Al) laminate, and composite powders obtained by coating these powders (e.g., titanium oxide-coated borosilicate (Ca / Al), titanium oxide-coated borosilicate (Ca / Na)). The brilliant pigment (a2) in the present invention can be any of the above, and can be used alone or in combination of two or more.

[0022] When the glittering pigment (a) in the aqueous cosmetic of the present invention contains glittering pigments (a1) and (a2), it is preferable that the average particle size of the glittering pigment (a1) and the average particle size of the glittering pigment (a2) are different. The difference in average particle size between the two pigments results in a non-uniform shine, resulting in a more glittery appearance. The difference in average particle size between the glittering pigment (a1) and the glittering pigment (a2) may be, for example, 20 μm or more. The blending ratio of the glittering pigments (a1) and (a2) can be appropriately determined taking into account the average particle sizes of the two pigments and the type of container.

[0023] The bright pigment (a2) that can be used in the present invention is commercially available, and commercially available products can also be used. For example, Glare Crystal Nova Silver GL-9091B (average particle size 39.785 μm), Glare Crystal Nova Silver GL-9091P (average particle size 82.5 μm) (CQV), DK PEARL-GFAG (average particle size 70 μm), DK PEARL-GFIF BLUE (average particle size 73.8 μm) (all from Daito Kasei Kogyo), Microglass Metashine MT1018ZB (average particle size 18 μm), Microglass Metashine MT1018ZR (average particle size 18 μm), Microglass Metashine MT1018ZG (average particle size 18 μm), Microglass Metashine MT1030ZB (average particle size 30 μm), Microglass Metashine MT1030ZR (average particle size 30 μm), Microglass Metashine MT1030ZG (average particle size 30 μm), Microglass Metashine MT1080ZB (average particle size Preferred commercially available products include Microglass Metashine MT1080ZR (average particle diameter 80 μm), Microglass Metashine MT1080ZG (average particle diameter 80 μm), Microglass Metashine MT1120ZB (average particle diameter 120 μm), Microglass Metashine MT1120ZG (average particle diameter 120 μm), Microglass Metashine MT1120ZR (average particle diameter 120 μm) (all Nippon Sheet Glass), and Aluminum Flake NO Silver 0.125 mm (average particle diameter 125 μm) (Kakuhachi Fish Scale Foil).

[0024] The content of the glittering pigment (a2) in the aqueous cosmetic of the present invention may be, for example, 0.1 to 19.9% ​​by mass, preferably 0.5 to 14.7% by mass, and particularly preferably 1.0 to 9.5% by mass, when the total mass of the aqueous cosmetic is taken as 100%. By including the glittering pigment (a2) in the above range, the glittering effect and metallic effect of the glittering pigment (a1) can be further improved.

[0025] Component (b) is an acrylic resin emulsion. Component (b) is incorporated as a film-forming agent. The acrylic resin emulsion (b) of the present invention is not particularly limited as long as it can be incorporated into cosmetics. However, it is preferably an emulsion of a resin whose raw monomer is one or more compounds selected from (meth)acrylic acid or its alkyl esters, or styrene. Specific examples include alkyl (meth)acrylate (C1-4 and C8) copolymer emulsions, acrylic ester-methacrylic ester copolymer emulsions, and alkyl (meth)acrylate-styrene copolymer (styrene / acrylates) copolymer) emulsions. Any one of these emulsions can be used alone or in combination. Note that "(meth)acrylic" refers to "methacrylic or acrylic." The acrylic resin emulsion (b) in the aqueous cosmetic of the present invention is preferably a styrene / acrylates copolymer emulsion, an acrylates copolymer, or an acrylates / ethylhexyl acrylate copolymer.

[0026] The acrylic resin emulsion (b) usable in the present invention is commercially available, and commercially available products can also be used. Preferred commercially available products include DAITOSOL 5000STY, DAITOSOL 5000AD, DAITOSOL 5000SJ, DAITOSOL 4000SJT, DAITOSOL 5500GX, and DAITOSOL 5000PO (all manufactured by Daito Chemical Industry Co., Ltd.), Yodosol GH34F and Yodosol GH800F (manufactured by Nouryon Japan Co., Ltd.), Vinizol 1086DB, Vinizol 1087FT, Vinizol 1089HT, Vinizol 1012JC, Vinizol 1013JH, Vinizol 2140L, Vinizol 2140LH, Vinizol 1086WP, Vinizol 1087FT, and Vinizol 1089HT (manufactured by Daido Chemical Industry Co., Ltd.).

[0027] The content of acrylic resin emulsion (b) in the aqueous cosmetic of the present invention is 1 to 10% by mass, calculated as solid content, when the total mass of the aqueous cosmetic is taken as 100%. Within this range, both good cosmetic effects and stable ejection can be achieved. On the other hand, if the content of acrylic resin emulsion (b) is less than 1% by mass, durability decreases and liquid leakage occurs over time. Furthermore, if the content of acrylic resin emulsion (b) exceeds 10% by mass, ejection failure and liquid leakage over time occur. The content of acrylic resin emulsion (b) in the aqueous cosmetic of the present invention is preferably 2 to 9% by mass, and particularly preferably 3 to 8% by mass.

[0028] Component (c) is a thickener selected from the group consisting of cellulose gum, hydroxypropyl methylcellulose, and hydroxyethyl cellulose. The thickener (c) in the present invention can be used alone or in combination of two or more selected from the above.

[0029] The thickener (c) that can be used in the present invention is commercially available, and commercially available products can also be used. For example, CMC Daicel <1330> (Daicel Corporation), HEC Daicel SE600 (Daicel Corporation), HEC Daicel SE900 (Daicel Corporation), Metrose 60SH-4000 (Shin-Etsu Chemical Co., Ltd.), Sangelose 60L (Daido Chemical Industry Co., Ltd.), Sangelose 90L (Daido Chemical Industry Co., Ltd.), and the like can be given as preferred commercially available products.

[0030] The content of thickener (c) in the aqueous cosmetic of the present invention is 0.01 to 1% by mass, assuming the total mass of the aqueous cosmetic to be 100%. By using a thickener selected from the above within this range, it is possible to obtain uniform glitter and non-smearing lines, and to improve stability over time in high-temperature environments. On the other hand, if the content of thickener (c) is less than 0.01% by mass, leakage over time and bleeding during application occur. Furthermore, if the content of thickener (c) exceeds 1% by mass, poor discharge of the glitter and bulk occurs, resulting in smearing. The content of thickener (c) in the aqueous cosmetic of the present invention is preferably 0.02 to 0.5% by mass, and particularly preferably 0.08 to 0.2% by mass.

[0031] The aqueous cosmetic preparation of the present invention may optionally further comprise component (d), an anionic or nonionic acrylic polymer. The anionic or nonionic acrylic polymer (d) may be blended into the aqueous cosmetic preparation of the present invention as an optional film-forming agent.

[0032] The anionic acrylic polymer may preferably be an AMP (2-amino-2-methyl-1-propanol) salt of a copolymer formed from one or more compounds selected from (meth)acrylic acid or its alkyl esters as raw material monomers. Specific examples include acrylate copolymer AMP and (C1-4 and C8 alkyl acrylate / diacetone acrylamide) copolymer AMP. Nonionic acrylic polymers include (hydroxyethyl acrylate / methoxyethyl acrylate) copolymer and (dimethylacrylamide / hydroxyethyl acrylate / methoxyethyl acrylate) copolymer. The anionic or nonionic acrylic polymer (d) of the present invention may be one or a combination of two or more selected from these.

[0033] The anionic or nonionic acrylic polymer (d) is preferably dissolved in any solvent that can be used in cosmetics, usually water, ethanol, propylene glycol, a mixture of these, or denatured alcohol.

[0034] The anionic or nonionic acrylic polymer (d) that can be used in the present invention is commercially available, and commercially available products can also be used. For example, P-7279A (Acrylates Copolymer AMP: Daido Chemical Industry Co., Ltd.), Dynamics (Akzo Nobel), Plassize L-3200B (Gooh Chemical Industry Co., Ltd.), Plassize L-53P (Gooh Chemical Industry Co., Ltd.), Plassize L-6010 (Gooh Chemical Industry Co., Ltd.), Plassize L-2700 (Gooh Chemical Industry Co., Ltd.), etc. can be mentioned as preferred commercially available products.

[0035] The content of the anionic or nonionic acrylic polymer (d) in the aqueous cosmetic of the present invention is preferably 0.35 to 1.75 mass%, and particularly preferably 0.5 to 1.5 mass%, when the total mass of the aqueous cosmetic is taken as 100%. Within this range, a good cosmetic can be obtained. On the other hand, if the content of the anionic or nonionic acrylic polymer (d) is less than 0.35 mass%, friction resistance may decrease. Furthermore, if the content of the anionic or nonionic acrylic polymer (d) is more than 1.75 mass%, ejection failure may occur.

[0036] The aqueous cosmetic preparation of the present invention may optionally further contain bentonite as component (e). Bentonite (e) may be blended into the aqueous cosmetic preparation of the present invention as an optional thickener.

[0037] The content of bentonite (e) in the aqueous cosmetic of the present invention is, for example, 0.05 to 1% by mass, preferably 0.08 to 0.5% by mass, and particularly preferably 0.08 to 0.29% by mass, when the total mass of the aqueous cosmetic is taken as 100%. Within the above range, a good cosmetic can be obtained. On the other hand, if the content of bentonite (e) is less than 0.05% by mass, poor glitter ejection may occur. Furthermore, if the content of bentonite (e) exceeds 1.75% by mass, ejection may become unstable or liquid leakage may occur over time.

[0038] In addition to the above-mentioned components, the aqueous cosmetic preparation of the present invention can contain other components commonly used in cosmetics, quasi-drugs, pharmaceutical compositions, etc., as long as the effects of the present invention are not impaired. Examples of such other components include colorants (powder and pigments other than the above component (a)), humectants, thickeners other than the above components (c) and (e), dispersants, dyes, lower alcohols, ultraviolet absorbers, organic acids, organic amines, sequestering agents, pH adjusters, antioxidants, preservatives, fragrances, and water.

[0039] The method for producing the aqueous cosmetic composition of the present invention is not particularly limited, and the composition can be produced using a mixer or disperser that is commonly used for mixing and dispersing aqueous cosmetics.

[0040] The aqueous cosmetic composition of the present invention can be used for eye makeup cosmetics and can be made into a product form by filling it into a pen-shaped container, for example. The pen-shaped container that can be used in the present invention is a direct-fill or padded automatic pen-shaped container that naturally dispenses the cosmetic composition by the action of the surface tension and capillary action of the cosmetic composition. The specific product form of the aqueous cosmetic composition of the present invention is not particularly limited, but is preferably an eyeliner. [Example]

[0041] The present invention will be further described below with reference to examples, which should not be construed as limiting the scope of the present invention.

[0042] <Examples 1 to 30 and Comparative Examples 1 to 15: Eyeliner Cosmetics> Eyeliner cosmetics were prepared using the compositions shown in Tables 1 to 4 and the manufacturing methods described below. Examples 1 to 8 and 20 to 30 and Comparative Examples 1 to 4 and 13 to 15 were evaluated for three items: "bleeding of drawn lines," "discharge of glitter pigment," and "leakage over time." Examples 9 to 19 and Comparative Examples 5 to 12 were evaluated for the above three items plus "metallic effect" and "glitter effect," a total of five items, using the evaluation methods and criteria described below. The results are also shown in the tables. The values ​​in the tables are in mass %.

[0048] [Manufacturing method] Purified water was added to components (a) to (c), and the mixture was dispersed using a disperser (Homodisper 2.5 type DH-2.5, manufactured by PRIMIX Corporation), after which the other components were added and mixed to prepare the emulsion.

[0049] [Evaluation method and criteria] a. Bleeding (Evaluation method) The prepared cosmetic was filled into a container and applied to the front of the forearm in a line of approximately 3 cm. At this time, it was visually confirmed that the cosmetic did not spread along the wrinkles or grooves of the skin, and that the boundary between the line and the skin was clear. (Evaluation criteria) ◎: The lines do not smudge and the boundary between the lines and the skin is clear Good: The lines are barely smudged, and the boundary between the lines and the skin is slightly unclear. ×: The lines are blurred and the boundary between the lines and the skin is unclear.

[0050] b. Discharge stability of bright pigments (Evaluation method) The prepared cosmetic was filled into a container and left to stand horizontally for one week at room temperature or 50°C. A writing test (three lines of approximately 3 cm each were drawn on high-quality paper) was conducted on the cosmetic after one week of storage and the cosmetic immediately after preparation, and the state of ejection of the glitter pigment was compared visually. (Evaluation criteria) ◎: Luminous pigment is evenly distributed on the drawn lines ◯: There are some uneven areas, but the luster pigment is almost uniformly distributed on the lines. △: The luster pigment is unevenly distributed on the drawn lines. ×: The glittering pigment is not present in the drawn lines, or the amount of glittering pigment discharged has clearly decreased over time compared to immediately after production.

[0051] c. Leaking liquid (Evaluation method) The prepared cosmetic was filled into a container and stored face down at room temperature or 50°C for one week. After one week of storage, the inside of the container cap was visually inspected to check for leakage from the brush tip. Furthermore, the presence or absence of liquid pooling at the brush tip was also checked. (Evaluation criteria) ◎: No liquid leaks inside the cap, and no liquid pools on the tip of the brush. 〇: No liquid leaks inside the cap, but there is some liquid pooling at the tip of the brush. ×: Liquid is leaking inside the cap.

[0052] d.Metallic feel (Evaluation method) A writing test similar to that in b above was conducted, and the drawn lines were visually inspected to see whether the entire drawn line had a glossy feel (metallic feel). (Evaluation criteria) 1: There is enough metallic feeling 2: Has a metallic feel 3: Has a slight metallic feel 4: Slight metallic effect 5: No metallic feel at all

[0053] e. Glitter (Evaluation method) A writing test similar to that in b above was conducted, the drawn lines were visually inspected, and the scattered feel of glitter in the drawn lines was confirmed. (Evaluation criteria) 1: Plenty of glitter 2: Has a shimmery feel 3: Has a slight shimmer 4: Slightly glittery 5: No glitter at all

[0054] [result] As is clear from the results in Tables 1 to 4, Examples 1 to 30, which are embodiments of the present invention, were aqueous cosmetics that excelled in all of the categories of "line bleeding," "discharge of glitter pigment," "leakage over time," "metallic effect," and "glitter effect." On the other hand, Comparative Example 1, which did not contain component (c), Comparative Example 2, which contained more than 1% by mass of component (c), and Comparative Examples 3 and 4, which used a thickener different from component (c), significantly impaired the evaluations of line bleeding, discharge of glitter pigment, and leakage over time (Table 1). With regard to the glitter pigment, Comparative Example 9, which used a glitter pigment different from component (a), failed to achieve either a metallic or glitter effect, while Comparative Examples 5 to 8, which contained only component (a2) but not component (a1), only achieved either a glitter effect or a metallic effect (Table 2). In Comparative Example 10, where the content of component (a1) exceeded 20% by mass, ejection properties were significantly impaired, and in Comparative Examples 11 and 12, where the content of component (a) (i.e., the total amount of components (a1) and (a2)) was less than 1% by mass, no metallic or glittery effect was obtained (Table 3). In Comparative Example 13, which did not contain component (b), Comparative Example 14, where the content of component (b) was less than 1% by mass, and Comparative Example 15, where the content of component (b) exceeded 10% by mass, the evaluations of line bleeding, ejection of the luster pigment, and leakage over time were significantly impaired (Table 4).

[0055] <Prescription example> Based on the above examples, the following formulations are excellent in all aspects, including line bleeding, luster pigment ejection, liquid leakage over time, metallic effect, and glitter effect. The numerical value for each component is the mass % of that component when the total mass of the cosmetic is taken as 100%. The symbols indicate the corresponding essential components.
