Description

Technical Field

[0001] The present invention relates to a disintegrating granule composition or a cosmetic containing the same.

Background Art

[0002] Cosmetics have various dosage forms. In addition to functional requirements, there has been a demand for cosmetics with high aesthetic appearance that combine various colors and textures. Among them, in makeup cosmetics, there is a demand for cosmetics that emphasize aesthetic appearance by utilizing the color and texture of powders. As a specific example, in solid cosmetics, cosmetics that enhance aesthetic appearance by making full use of surface patterns are popular. Conventionally, efforts have been made in the shape maintenance of parts for making patterns and the improvement of filling techniques. Among them, in a powder-based dosage form, attempts have been made to obtain highly aesthetic cosmetics by combining a plurality of colors of a disintegrating granule composition. In a disintegrating granule composition, it is required to simultaneously have shape retention that can maintain the shape until it becomes a cosmetic, appropriate disintegration property that enables filling and molding, and good dispersibility for easy application during coating. On the other hand, in makeup cosmetics, darkening around the eyes is a major problem. In order to achieve a finish without darkening, it is necessary to cope with enhancing the impression around the eyes by blending a large amount of brightening powder or providing coverage for the skin around the eyes itself. Furthermore, around the eyes, in addition to fine movements, a cosmetic film with strong makeup retention against sweat and sebum is required. In order to solve such problems, a technique for obtaining a disintegrating granule composition for cosmetics by combining a cellulose-based water-soluble polymer and thin film pieces exhibiting a true pearl luster (brightening) due to a thin layer of optical interference color (see, for example, Patent Document 1), and a technique for obtaining spherical powder cosmetics by combining a powder and a water-swelling clay mineral as a binder (see, for example, Patent Document 2) are known.

Patent Document 1

[0004] However, in technologies such as Patent Document 1, which combine thin film fragments with a pearlescent luster with water-soluble polymers, while a remarkable cosmetic feel was achieved by realizing a pearlescent luster during use, the use of water-soluble polymers to maintain the shape of the granulated composition meant that the makeup did not last long enough against sweat. Furthermore, the use of water-soluble film-forming agents resulted in high cohesiveness of the powder, making uniform dispersion difficult and thus the effect of enhancing coverage was insufficient. Moreover, if the granulated composition was too hard, its disintegration properties were insufficient, sometimes causing problems with filling and molding in cosmetics. Additionally, in technologies such as Patent Document 2, which combine mica and mica titania with spherical powder and liquid oil, while improved usability was achieved, the level of shape retention was insufficient because only the liquid oil maintained the shape of the granulated composition. Therefore, the present invention aims to provide cosmetics that are excellent in terms of "coverage," "makeup longevity," and "aesthetic appearance" in the case of cosmetics, and in terms of "filling and molding properties" in the case of solid cosmetics, by using a granulated composition that can be used as a granulated composition and has "shape retention" which maintains a certain shape as a granulated composition before filling, and "disintegration properties" which allow the shape to be deformed during filling and have appropriate hardness that disperses and disintegrates when used. [Means for solving the problem]

[0005] In light of various circumstances, the inventors considered whether it would be possible to realize a granulated composition that achieves both shape retention and disintegration without using film-forming agents, etc., by using a semi-solid ester oil agent that has superior powder-to-powder bonding strength compared to liquid oil. As a result of diligent research, they found that by using a granulated composition that has "shape retention," which is the minimum standard of hardness that allows it to maintain a certain shape as a granulated composition before filling, and "disintegration," which is the upper standard of hardness that allows it to deform in shape during filling and disintegrate during use, the composition excels in "coverage," "makeup longevity," and "aesthetic appearance" in the case of cosmetics, and in "filling and molding properties" in the case of solid cosmetics, and thus completed the present invention.

[0006] Therefore, the present invention is as follows.

Examples of water-swellable clay minerals include smectite-type clay minerals such as bentonite, montmorillonite, heidellite, hectorite, saponite, stibnite, etc., kaolin, and swelling mica introduced with fluorine. These water-swellable clay minerals can be either of natural origin or synthetic products. For example, those mainly composed of magnesium aluminum silicate, sodium magnesium silicate, etc.

[0018] Component (C) of the present invention is preferably a synthetic polymer compound as the water-soluble polymer, and more specifically, a carboxyvinyl polymer or (acrylates / alkyl acrylate (C10-C30)) crosspolymer is preferred, and an alkyl-modified carboxyvinyl polymer having the function of holding oil is more preferred. Examples of commercially available water-soluble polymers of such component (C) include Carbopol 980 and Carbopol 1382 (both manufactured by LUBRIZOL). Furthermore, among water-swellable clay minerals, magnesium aluminum silicate is particularly preferred. Examples of commercially available water-swellable clay minerals include Smecton SA-2, SA, SWN, SWF, and Kunipia G4 (manufactured by Kunimine Industries Co., Ltd.). These may be contained individually or in combination of two or more. Including these is preferable because it can further enhance the shape retention and disintegration properties in granulated compositions, and the coverage in cosmetics.

[0019] The content of component (C) in the composition is not particularly limited, but the lower limit is preferably 0.2% or more, more preferably 0.5% or more, and even more preferably 1% or more. The upper limit is preferably 3% or less, more preferably 2% or less, and even more preferably 1.5% or less. This range is preferable from the viewpoint of shape retention and disintegration properties as a granulated composition. The content of component (C) in the cosmetic is not particularly limited, but the lower limit is preferably 0.1% or more, more preferably 0.25% or more, and even more preferably 0.5% or more. The upper limit is preferably 3% or less, more preferably 2% or less, and even more preferably 1.5% or less. This range is preferable from the viewpoint of coverage and filling moldability as a cosmetic.

[0020] In this invention, the mass ratio (B) / (C) of component (B) and component (C) is not particularly limited, but the lower limit is preferably 0.3 or higher, more preferably 2.5 or higher, and even more preferably 5.3 or higher. The upper limit is preferably 150 or lower, more preferably 40 or lower, and even more preferably 15 or lower. Within this range, among the various effects, the balance between the longevity of the cosmetic in terms of its ability to handle sweat and sebum, and the coverage power are particularly improved, making it preferable.

[0021] The present invention can be used in combination with component (D) metal soap. The metal soap in the present invention is not particularly limited as long as it is a metal soap commonly used in cosmetics, and its general formula is (RCOO)nM (wherein R represents an aliphatic hydrocarbon group having 10 to 18 carbon atoms, and M is a divalent or trivalent metal such as aluminum, zinc, magnesium, calcium, or iron. n is 1 or more and is limited to the valence of the metal M, but is not necessarily the same as the valence of M. One or more of these can be used. In particular, from the viewpoint of coverage, zinc salts, aluminum salts, calcium salts, and magnesium salts of stearic acid, palmitic acid, lauric acid, myristic acid, or behenic acid are preferred, zinc salts, aluminum salts, calcium salts, and magnesium salts of lauric acid are more preferred, and zinc laurate is even more preferred. The inclusion of component (D) is preferred because it has the effect of further enhancing filling moldability and coverage.

[0022] The content of component (D) is not particularly limited, but the lower limit is preferably 0.2% or more, more preferably 0.6% or more, and even more preferably 0.8% or more. The upper limit is preferably 2% or less, more preferably 1.5% or less, and even more preferably 1.2% or less. This range is preferable from the viewpoint of coverage.

[0023] The method for producing the disintegrating granular composition of the present invention is not particularly limited. For example, a disintegrating granular composition can be obtained by mixing component (A), component (B), and optionally component (C), component (D), and other components using a conventional method, pulverizing and granulating the mixture using a granulator or the like, and drying it in a dryer or the like to remove the solvent. It is preferable to include a step of drying and granulating using water as the solvent, as this can adjust the shape retention and disintegration properties of the granular composition. Furthermore, it is even more preferable to pre-mix component (C), component (B), and water, add the dispersion to a powder layer containing component (A) to create a granular composition, and then dry it. When this method is used, the dispersibility of component (B) or (C) may be improved, and it is preferable to select them as appropriate. Granulation methods include, for example, agitation granulation using a super mixer, extrusion granulation using a granulation grinder, and spray drying. Equipment used for granulation includes, for example, a super mixer (SMP-2 / manufactured by Kawata Co., Ltd.) and a disc atomizer (Spray Dryer SD12 / manufactured by Mitsui Mining Co., Ltd.). When obtaining a disintegrating granular composition with large particle sizes, agitation granulation is preferred, and when obtaining a disintegrating granular composition with small particle sizes, fluidized bed granulation is preferred. Furthermore, in granulation grinding, the disintegrating granular composition can be adjusted to the desired particle size by selecting the screen diameter according to the desired particle size. Any of these granulation methods can be selected according to the desired particle size. The disintegrating granular composition of the present invention is preferably obtained by mixing component (A), dissolved component (B), and optionally components (C) and (D), granulating the mixture, and then removing the water by vacuum suction, drying, or the like.

[0024] In this invention, a disintegrating granulated composition is obtained by granulating powder and disintegrates easily upon external stimuli such as pressure. Disintegration in this invention means that, using a static / dynamic friction measuring instrument TL201Tt (manufactured by Trinity Lab. Inc.), when a force is applied in a vertical direction to each grain of the granulated composition (average of 10 grains) using a conical adapter with a diameter of 5 mm at a speed of 2 mm / second, the maximum vertical stress required for disintegration is less than 3 gf.

[0025] Furthermore, the average particle size of the disintegrating granulated composition of the present invention is the value (median diameter D50) obtained by taking an image with a stereomicroscope when the granulated composition is arranged in a single layer without overlapping or disintegrating, and measuring it with an image analysis device (Luzex AP, manufactured by Nireco Corporation), and refers to the longest diameter of the particles. The lower limit of the average particle size of the disintegrating granulated composition of the present invention is 0.5 mm or more, preferably 0.6 mm or more, more preferably 1 mm or more, and even more preferably 1.5 mm or more. The upper limit is 4.0 mm or less, preferably 3.5 mm or less, more preferably 3 mm or less, and even more preferably 2.5 mm or less. Within this range, it is preferable from the viewpoint of shape retention and disintegration as a granulated composition, fillability as a cosmetic, and appearance aesthetics.

[0026] Furthermore, the cosmetic composition using the disintegrating granular composition of the present invention preferably contains 50% or more of the disintegrating granular composition of the present invention, more preferably 80% or more, and preferably 100% or less as the upper limit. This range is preferable because it is superior in terms of appearance and aesthetics. There are no particular restrictions on the type of cosmetic composition as long as it has an appearance and aesthetics in which the presence of the disintegrating granular composition can be visually confirmed in the cosmetic composition. In particular, a powdered solid cosmetic composition is preferable because it has superior appearance and allows the shape retention and disintegration properties of the granular composition to be utilized.

[0027] Furthermore, the method for producing a solid powder cosmetic using the disintegrating granular composition of the present invention is not particularly limited. Examples include filling a container with one or preferably two or more disintegrating granular compositions and then dry-compressing them, or mixing them with a solvent to form a slurry and then wet-filling it. Dry-compression molding is particularly preferred because it enhances the packing and molding effect of the present invention. Specifically, this method is preferred because it makes it easier to achieve a smooth packing and molding on the press surface after packing and molding. If the granular composition is too hard, i.e., has poor disintegration properties, air may not escape easily, and swelling due to internal stress may occur. Furthermore, the press pressure during dry-compression molding should be 20-30 kg / cm². 2This is more preferable in that it further enhances the above-mentioned effects. In particular, in the present invention, when a solid powder cosmetic contains powder or other components in addition to the disintegrating granular composition, the disintegrating granular composition and the powder or other components may be mixed and filled into a container. Furthermore, it is preferable to use a combination of two or more disintegrating granular compositions with different colors or textures, as this allows the colors to be scattered and further enhances the aesthetic appearance. It is also possible to mix them in advance before filling into a container.

[0028] The disintegrating granular composition of the present invention may contain, in addition to the above-mentioned components (A) to (D), components commonly used in cosmetics, such as water-swellable clay minerals of component (A) and component (C), powders other than component (D), oily components other than component (B), aqueous components other than the water-soluble polymer of component (C), surfactants, ultraviolet absorbers, humectants, antioxidants, beauty ingredients, sugars, preservatives, fragrances, etc., as long as they do not interfere with the effects of the present invention.

[0029] The powders other than the water-swellable clay minerals of components (A) and (C) and component (D) are not particularly limited as long as they are commonly used in cosmetics. For example, they are not particularly limited in terms of shape such as spindle-shaped, needle-shaped, fibrous, or spherical; particle size such as aerosol, fine particles, or pigment grade; and particle structure such as porous or non-porous. Inorganic powders, organic powders, pigment powders, and composite powders can all be used.

One or more of these can be used. Furthermore, these powders may be used as a single or composite of two or more types, and may be surface-treated using known methods with fluorine compounds, silicone oils, surfactants, oils and fats, hydrocarbons, etc.

[0030] Furthermore, the mass ratio of component (A) to the total amount of powder containing component (A), (A) / total amount of powder, is not particularly limited, but the lower limit is preferably 0.23 or higher, more preferably 0.47 or higher, and even more preferably 0.64 or higher, while the upper limit is preferably 0.95 or lower, more preferably 0.93 or lower, and even more preferably 0.83 or lower. This range is preferable from the viewpoint of coverage.

[0031] Other oily components besides component (B) are not particularly limited as long as they are commonly used in cosmetics, and may include hydrocarbons, fats and oils, waxes, hydrogenated oils, ester oils, fatty acids, higher alcohols, silicone oils, fluorinated oils, lanolin derivatives, oily gelling agents, etc., regardless of their origin (animal oils, vegetable oils, synthetic oils, etc.) or their properties (solid oils, liquid oils, volatile oils, etc.).

[0032] Furthermore, the ratio of component (B) to the total amount of oil containing component (B) (B) / total amount of oil is not particularly limited, but the lower limit is preferably 0.16 or higher, more preferably 0.5 or higher, and even more preferably 0.6 or higher. The upper limit is preferably 1 or lower, more preferably 0.85 or lower, and even more preferably 0.66 or lower. This range is preferable from the viewpoint of shape retention.

[0033] Examples of the solid powder cosmetic composition of the present invention include makeup cosmetics and skincare cosmetics, and various cosmetic forms can be used depending on the purpose. More specifically, examples of solid powder cosmetic compositions include foundation, blush, face powder, eyeshadow, eyeliner, eyebrow powder, and body powder. While not particularly limited, blush, eyeshadow, and eyebrow powder are preferred, with blush and eyeshadow being more preferred. Furthermore, it is preferable to mix two or more disintegrating granular compositions of different colors and textures to enhance the appearance and aesthetic appeal. [Examples]

[0039] (Method for producing granulated compositions: Table 1, Table 2) A. Mix ingredients (1) to (7) and (21) to (24) uniformly. B. Dissolve components (8) to (17) uniformly at 65°C. C. Disperse components (18) to (19) and component (20) by adding B. Mix DA, C, and component (25). After granulating the ED in a super mixer, it is ground using a speed mill (screen diameter 2 mmφ, however, for granulated compositions Examples 19 and 20, the screen diameter is 4 mm). The FE was dried at 70°C for 10 hours to obtain a granulated composition.

[0040] (Cosmetics using each granulation composition: Method for producing powdered solid eyeshadow: Tables 1 and 2) A. The granulated composition (and other components) is uniformly mixed and filled into a metal tray. BA was compressed and molded to obtain a powdered solid eyeshadow.

[0041] (Evaluation method for granulated compositions) i. Shape retention Shape retention refers to the minimum hardness required for a granulated composition to maintain a certain shape before filling, making it suitable for use in cosmetics. 3g of each of Granulated Composition Examples 1-25 and Granulated Composition Comparative Examples 1-4 were placed in centrifuge tubes and shaken for 10 minutes using a shaker (Yayoi YS-8D) with a stroke width of 80mm and 180 reciprocations per minute. Each sample was then passed through a 600μm mesh, and the weight of the sample that did not pass through was measured to calculate the retention rate. Shape retention was then determined according to the following criteria. The retention rate was calculated using the weight of the material that did not pass through the 600μm mesh as the numerator and the amount of material added as the denominator. (Judgment criteria) (Judgment): (Survival rate) ◎: 70% or more ○: 50% or more but less than 70% △: 30% or more but less than 50% ×: Less than 30%

[0042] b. Disintegration Disintegration refers to the upper limit of hardness required for a granulated composition to be included in a cosmetic, deformable during filling, and disintegrate during use. Disintegration was evaluated for each of the granulated composition examples 1-25 and comparative examples 1-4 using a static / dynamic friction measuring instrument TL201Tt (manufactured by Trinity Lab. Inc.). Using a 5 mm diameter conical adapter, the maximum vertical stress required for disintegration was measured when a force was applied perpendicularly to one granulated composition particle at a speed of 2 mm / second, and this was evaluated as disintegration. The above measurement was repeated three times for each sample, and the average maximum stress value was judged according to the following criteria. Judgment criteria: [Judgment]: [Average maximum stress value] ○: Less than 3gf × :3gf or more

[0043] (Evaluation method for cosmetics containing granulated compositions) H. Makeup longevity Cosmetic Examples 1-25 and Cosmetic Comparative Examples 1-4 were each applied in 0.1g portions to a 2cm x 3cm area of ​​black artificial leather (manufactured by Ideatex Japan Co., Ltd.). Then, 0.5ml of simulated sebum was dropped onto the area, and after 1 minute, the area was rubbed five times with a tissue. The condition of the cosmetic film was visually evaluated, and the area of ​​black where the film had peeled off was noted. Sebum resistance was determined according to the following criteria. An example of the evaluation results is shown in the figure. (Judgment criteria) (Judgment): (Evaluation) ◎: The remaining makeup film on the rubbed area is 80% or more. ○: The remaining percentage of the cosmetic film on the rubbed area is between 50% and 80%. △: The remaining percentage of the cosmetic film on the rubbed area is between 20% and 50%. ×: Less than 20% of the cosmetic film remains on the rubbed area.

[0044] 2. Coverage The surface color of unused molded products filled with cosmetic examples 1-25 and cosmetic comparative examples 1-4, and the surface color (L*a*b*) after applying 0.1g to a 2cm x 3cm area of ​​artificial leather (manufactured by Ideatex Japan Co., Ltd.) were measured using a colorimeter (manufactured by Nippon Denshoku Co., Ltd.), and the color difference ΔE was calculated to determine the coverage according to the following criteria. (Judgment criteria) (Judgment): (Evaluation) ◎ :ΔE≧55 〇 :55>ΔE≧50 △ :50>ΔE≧45 × :45>ΔE

[0045] E. Filling and molding properties Cosmetic composition examples 1-25 and cosmetic composition comparative examples 1-4 were each filled with 10g of each into a circular metal dish with a diameter of 6cm and a thickness of 5mm. They were then automatically pressed at 200N at a speed of 3cm / second for 1.5 seconds, and after release, the swelling was observed after 1 hour. The filling moldability was then determined according to the following evaluation criteria. Five pieces were pressed, and the worst-pressed piece was evaluated. Swelling is a phenomenon that occurs when the granulated composition does not collapse sufficiently during pressing and attempts to return to its original shape when the pressure is removed. It was used as an indicator to confirm the filling moldability of the granulated composition. (Judgment criteria) (Judgment): (Evaluation) ◎: No swelling. ○: Less than 0.1 cm from the surface and almost no bulge. △: There is a bulge of 0.1 cm or more but less than 1 cm from the surface. ×: There is a bulge of 1 cm or more from the surface.

[0046] To, the aesthetic appearance Cosmetic Examples 1-25 and Cosmetic Comparative Examples 1-4 were each subjected to usage tests by a panel of 20 cosmetic experts. All evaluators visually assessed each sample, evaluating whether the granulated composition's shape remained clearly defined and filled, and whether the boundaries were blended. Each evaluator assigned a score on a 5-point scale according to the following evaluation criteria, and the average score from all panel members was calculated to determine the aesthetic appearance according to the following criteria. (Evaluation Criteria) (Rating): (Content) 4: Very good 3: Quite good 2: Good 1: Bad 0: Very bad (Judgment criteria) (Judgment): (Average score) ◎: 3 points or more ○: 2 points or more but less than 3 points △: 1 point or more but less than 2 points ×: Less than 1 point [Brief explanation of the drawing]

[0048] As is clear from the results in Tables 1 and 2, the granulated compositions of the present invention, Examples 1 to 26, were excellent in all aspects of shape retention and disintegration. In contrast, Comparative Example 1, which did not contain component (B), was weak against external stimuli and had poor shape retention. Furthermore, Comparative Example 2, which used a non-polar semi-solid ester oil instead of component (B), and Comparative Examples 3 and 4, which used solid oil, had good shape retention but poor disintegration.

[0049] Furthermore, the eyeshadows of cosmetic examples 1 to 26, made using 100% of each of the granulated composition examples 1 to 26, were excellent in all aspects of makeup longevity, coverage, filling and moldability, and aesthetic appearance, as is clear from the results in Tables 1 and 2. In contrast, cosmetic comparative example 1 was particularly inferior in terms of makeup longevity, coverage, and aesthetic appearance. Cosmetic comparative example 2 was inferior in makeup longevity, and cosmetic comparative examples 3 and 4 were inferior in makeup longevity, coverage, and filling and moldability.
