BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the details of the present invention will be described with reference to the accompanying drawings.
FIG. 1 is a partially cutaway side view showing an embodiment of a makeup tool (makeup brush) according to the present invention, and FIG. 2 is a side view showing a storage state of the makeup tool (makeup brush) of FIG.
[0010]
The makeup tools to which the present invention is applied include makeup brushes (see FIGS. 1 and 2), compacts, lipsticks, and other publicly known makeup tools.
[0011]
The cosmetic tool body 1 of the present invention is made of an aluminum material, and after polishing the surface (for example, bath polishing) to a mirror surface state, it is alumite-treated a plurality of times, and then a sebum adhesion suppression layer is formed. It is. In this specification, the makeup tool body 1 refers to a handle and a cap in the case of a makeup brush, and a body and a lid when housed in a container such as a lipstick or a compact, that is, a portion that is mainly touched during use. say.
[0012]
In order to obtain the cosmetic tool of the present invention, first, the surface of the cosmetic tool body 1 made of an aluminum material is polished and mirror-finished.
[0013]
After mirroring, anodizing is performed multiple times. In order to form the alumite layer 2, first, a cosmetic tool whose surface is roughened in acetone, surfactant, alcohol, or the like placed in a bath set at a temperature between room temperature and boiling point. The cosmetic tool body 1 is degreased by immersing the body 1 for several minutes to several tens of minutes. Next, water is washed by spraying tap water onto the makeup tool body 1 by spraying or immersing the makeup tool body 1 in tap water. In addition, the temperature of the washing water at the time of washing with water may be about room temperature. Subsequently, the cosmetic tool body 1 is immersed in an aqueous electrolyte solution, and the alumite layer 2 is formed by an anodic oxidation method. After layer formation, drying is performed for several minutes to several tens of minutes.
[0014]
The surface roughness of the surface of the obtained alumite layer 2 may be in a known range.
[0015]
Next, the sebum adhesion suppression layer 3 is formed on the surface of the alumite layer 2, but before that, a part or most of the surface of the makeup tool body 1 located on the lower surface of the alumite layer 2 is processed with a satin finish. By dividing into a part that has been subjected to the mirror finish and a part that has been subjected to a satin finish, it is possible to display decorations, product names, product symbols, trademarks, and the like. That is, the region that maintains the mirror surface state is masked by masking printing, etc., anodized, peeled by chemical treatment in this state, and anodized, so that the makeup tool body other than the masked printed region The lower surface of the anodized layer, which is the surface, can be in a satin state.
[0016]
As the means for performing the satin processing, chemical processing is preferable, but there is one or a combination of two or more of hairline processing, sanding processing, sand blast processing, etching processing, knurling processing, press processing and the like.
[0017]
The satin processing may be performed after the first alumite treatment, may be performed after all the alumite treatment is completed, or may be performed a plurality of times.
[0018]
The sebum adhesion suppression layer 3 is applied to the surface of the alumite layer 2 after a plurality of alumite treatments and satin processing.
[0019]
In the sebum adhesion suppression method according to the present invention, a powder in which ion release components such as Ag ions and Cu ions are homogeneously contained on the glass particle surface in a stable manner on the surface of the anodized layer 2 of the cosmetic tool body 1 is formed with a transparent paint. In this method, the sebum adhesion suppression layer 3 is applied.
[0020]
A powder containing the ion-releasing component homogeneously on the glass particle surface in a stable form can be obtained, for example, by the following steps.
[0021]
(1) Glass raw material mixing step In this step, glass raw materials such as Ag ₂ O, ZnO and P ₂ O ₅ are accurately weighed and then mixed uniformly. When mixing, it is preferable to use a mixing machine (mixer) such as an alumina porcelain crusher, a ball mill, or a propeller mixer.
[0022]
(2) Glass raw material melting step In this step, glass raw material mixed uniformly is melted using a glass melting furnace or the like to create molten glass. From the viewpoint of increasing production efficiency and from the viewpoint of reducing yellowing of the soluble glass during production as much as possible, the melting temperature is 600-1500 ° C., and the melting time is 0.1-24. Adopt time conditions .
[0023]
(3) Dissolving glass pulverization step The molten glass obtained is pulverized into fine particles, that is, a powder. Specifically, it is preferable to perform coarse pulverization (including water pulverization) and fine pulverization from the viewpoint of efficiently obtaining glass particles having a uniform particle diameter. After this step, it is also preferable to carry out a classification step. For example, after obtaining a powder of 1 to 20 μm, it is preferable to classify and use a 3 μm powder.
[0024]
Next, the transparent paint used when applying the powder obtained by the above process is special if it is a publicly known and commonly used transparent paint applied to this type of cosmetic tool or cosmetic container. Can be used without limitation.
[0025]
For example, it is a paint containing the transparent resin shown below.
Preferred transparent resins include polyethylene resin (PE), polypropylene resin (PP), polyethylene terephthalate resin (PET), polybutylene terephthalate resin (PBT), polycarbonate resin (PC), styrene resin (PS), vinylidene chloride resin, List one or more of vinyl acetate resin, polyvinyl alcohol resin, fluorine resin, polyarylene resin, acrylic resin, epoxy resin, transparent vinyl chloride resin, ionomer resin, polyamide resin, polyacetal resin, etc. be able to.
[0026]
In addition, when using such kind of transparent resin, it is preferable to use what has the light transmittance specifically defined by the following formula within the range of 50 to 100%, more preferably 80 to 100%. One having a light transmittance in the range of 100% is used. Further, the transmitted light amount and the incident light amount can be measured using an absorptiometer or a light meter (power meter). In the measurement, for example, a transparent resin having a plate shape with a thickness of 1 mm can be used.
Light transmittance (%) = transmitted light amount / incident light amount × 100
[0027]
The amount of powder mixed into the transparent paint is appropriately determined depending on the type of makeup tool used, etc. For example, the amount of powder mixed per 100 parts by weight of resin is a value within the range of 0.01 to 10 parts by weight. To do. The reason for this is that when the amount of mixed powder is less than 0.01 parts by weight, the effect of suppressing sebum adhesion may be reduced. On the other hand, when the amount of mixed powder exceeds 10 parts by weight, the mechanical strength of the surface coating film is reduced. This is because there is a case where mixing is difficult, mixing is difficult, or transparency is lowered. Therefore, from the viewpoint of more preferable balance between sebum adhesion inhibiting effect and mechanical strength in the transparent resin composition, the amount of powder mixed per 100 parts by weight of resin is a value within the range of 0.3 to 5 parts by weight. It shall be the.
[0028]
Next, as a method of applying the powder with a transparent paint, a publicly known means or method for applying a transparent paint to the surface of the makeup tool body 1, that is, the surface of the alumite layer 2, can be employed. Such a coating method is not particularly limited, and a bar coating method, a spray coating method, a knife coating method, a gravure coating method, a dipping method, and the like can be employed. In that case, a transparent paint is laminated | stacked on the surface of the makeup | decoration tool main body 1, ie, the surface of the alumite layer 2, by the thickness of 20-1000 micrometers. The reason for this is that when the thickness of the transparent coating is less than 20 μm, the adhesion to the surface of the cosmetic tool body 1, that is, the surface of the alumite layer 2 may be reduced, while when the thickness exceeds 1000 μm, This is because it may be difficult to uniformly laminate the surface, or may be detached from the surface of the makeup tool body 1, that is, the surface of the alumite layer 2. Note that you the thickness of the toilet set body 1 a value within the range of 5 ~ 500 μm. After coating, the solution in the coating film is volatilized by heating and drying, and then the coating film is cured by heating, humidification, ultraviolet irradiation, electron beam irradiation, and the like.
[0029]
Since the surface of the cosmetic tool body 1 is anodized, the adhesion of the sebum adhesion inhibiting layer 3 to the anodized layer 2 that is the surface of the cosmetic tool body 1 is high. This is because the alumite layer 2 is composed of transparent hexagonal crystals, each crystal has holes with a diameter of about 1500 nm, and the alumite layer 2 is formed with the holes unsealed. This is because, since the sebum adhesion suppressing layer 3 is formed on the surface, the transparent paint of the sebum adhesion suppressing layer 3 enters the hole and an anchor effect is obtained.
[0030]
A hard coat layer may be provided between the alumite layer 2 and the sebum adhesion suppression layer 3 in order to improve the hardness of the surface of the cosmetic tool body 1 and prevent scratches due to scratches.
[0031]
The hard coat layer needs to be made of a polymer containing a polyfunctional monomer containing a (meth) acryloyloxy group as a main component. Examples of the polyfunctional monomer include 1,4-butanediol di (meth) acrylate, 1,6-hexanediol di (meth) acrylate, neopentyl glycol (meth) acrylate, ethylene glycol di (meth) acrylate, tri Ethylene glycol di (meth) acrylate, tripropylene glycol di (meth) acrylate, dipropylene glycol di (meth) acrylate, 3-methylpentanediol di (meth) acrylate, diethylene glycol bis β- (meth) acryloyloxypropionate, tri Methylolethane tri (meth) acrylate, trimethylolpropane tri (meth) acrylate, pentaerythritol tri (meth) acrylate, dipentaerythritol hexa (meth) acrylate, tri (2 Hydroxyethyl) isocyanate di (meth) acrylate, pentaerythritol tetra (meth) acrylate, 2,3-bis (meth) acryloyloxyethyloxymethyl [2.2.1] heptane, poly 1,2-butadiene di (meth) Acrylate, 1,2-bis (meth) acryloyloxymethylhexane, nonaethylene glycol di (meth) acrylate, tetradecane ethylene glycol di (meth) acrylate, 10-decanediol (meth) acrylate, 3,8-bis (meth) Acryloyloxymethyltricyclo [5.2.10] decane, hydrogenated bisphenol A di (meth) acrylate, 2,2-bis (4- (meth) acryloyloxydiethoxyphenyl) propane, 1,4-bis (meta ) Acryloyloxime Examples include chill) cyclohexane, hydroxypivalate ester neopentyl glycol di (meth) acrylate, bisphenol A diglycidyl ether di (meth) acrylate, and epoxy-modified bisphenol A di (meth) acrylate. Only one type of polyfunctional monomer may be used, or two or more types may be used in combination. Further, if necessary, it can be copolymerized in combination with a monofunctional monomer.
[0032]
A (meth) acryloyloxy group means an acryloyloxy group or a methacryloyloxy group, a (meth) acrylate means an acrylate or a methacrylate, and the other compounds described above are the same.
[0033]
If the film thickness of the hard coat layer is 3 μm or more, the strength is sufficient, but a range of 5 to 7 μm is preferable from the viewpoint of transparency, coating accuracy, and handling.
[0034]
For the hard coat layer, an inorganic or organic fine particle having an average particle size of 0.01 to 3 μm is mixed and dispersed. Alternatively, a light diffusing treatment generally called anti-glare can be performed by making the surface shape uneven. These fine particles are not particularly limited as long as they are transparent, but a low refractive index material is preferable, and silicon oxide and magnesium fluoride are preferable in terms of stability, heat resistance, and the like. As long as these hard coat layers are uniformly coated, any coating method may be used.
[0035]
The cosmetic tool obtained by the method for suppressing sebum adhesion according to the present invention described above is the attachment of fingerprints to the surface of the cosmetic tool when handled with bare hands, that is, the fingerprint of the user's fingers due to the oil content (sebum). Not only the adhesion but also the adhesion of fingerprints can be suppressed not only by the cosmetics adhered to the finger or the cosmetic tool when handling the cosmetics.
[0036]
【Example】
Hereinafter, a film was applied to the surface of an aluminum tube (length: 10 cm, diameter: 2 cm, wall thickness: 0.5 mm) corresponding to the makeup tool body, and the sebum adhesion property was examined.
[0037]
Example 1
The surface of the makeup tool body 1 made of an aluminum tube was polished by a bath to obtain a mirror surface.
Next, after anodizing, masking printing was performed, anodizing was performed, and the surface of the cosmetic tool body 1 was textured by chemical treatment. After anodizing again, the masking was peeled off to form an anodized layer 2.
Next, 5 parts by weight of a powder that contains ion release components such as Ag ions and Cu ions in a stable form on the surface of glass particles classified to 3 μm is contained and dispersed in a transparent paint consisting of 100 parts by weight of an acrylic resin. The obtained transparent paint was applied to the surface of the alumite layer 2 with a thickness of 50 μm to form a sebum adhesion suppression layer 3.
[0038]
Comparative Example 1
Example 1 except that a transparent paint made of an acrylic resin was applied without using a powder containing an ion release component such as Ag ion or Cu ion in a stable form on the surface of glass particles classified to 3 μm. And so on.
[0039]
About the aluminum tube of Evaluation Example 1 and Comparative Example 1, a finger was pressed for a few seconds to attach a fingerprint, and a visual judgment was made as to whether the finger was easily attached or noticeable. While the attached fingerprint was not noticeable at all, Comparative Example 1 could easily recognize the adhesion of the fingerprint.
[0040]
Next, when a finger with a foundation was pressed for several seconds and a visual determination was made in the same manner, the adhesion of the fingerprint was recognized but not noticeable, whereas the comparative example 1 was clearly It was noticeable that the fingerprint was attached, and it was noticeable.
[0041]
【The invention's effect】
ADVANTAGE OF THE INVENTION According to this invention, the sebum adhesion suppression method of a cosmetic tool and a cosmetic tool which do not reduce a clean feeling and aesthetics by suppressing adhesion of sebum can be provided.
That is, not only fingerprints on the surface of cosmetic tools when handling with bare hands, that is, fingerprints due to oils (sebum) on user's fingers, but also on fingers and cosmetic tools when handling cosmetics. Since the attachment of fingerprints can be suppressed even with the cosmetics that have been made, the cleanliness and aesthetics or high-class feeling required of the cosmetic tool are not impaired.
