Description

Tablet external preparation

The present invention relates to a sheet-like external agent in which an oily external agent is coated on a substrate sheet and protected by a coating film. The sheet external preparation of the present invention is suitable for accommodating oily external preparations which can be applied to various parts of the skin, such as the stratum corneum, hair, nails, etc., which have keratin as the main component. The oily external preparations are not easy to adhere to the side of the coating film. , And the oily topical is also excellent in finger picking.

In recent years, through fashion magazines or the Internet, the awareness of makeup and beauty has spread to the younger age group centered on teens, and the demand for low-price cosmetics that children can easily buy has increased. Among them, the small and thin people who use it up in one time do not take up volume even if they have many types, and have excellent portability, so they may also be used as a novel social tool for friends to exchange or give gifts to each other. Also, in various press conferences and events, there are more opportunities to challenge the bold makeup that is different from usual. In order to complete the same makeup as expected, a wide range of makeup materials must be prepared. Therefore, color cosmetics that are rich in color change, disposable, and cheap to buy are not only attractive to younger people, but also attractive to adults.

Moreover, as for external preparations other than cosmetics, for example, skin, hair, nail care, cleansing, insect repellent, and other external preparations, if they are small and thin, they do not take up volume and are excellent in portability. It is especially convenient when traveling or traveling. Furthermore, the type that is used up in one time is excellent in hygiene because it is used immediately after opening.
As described above, regardless of the user layer or the application, it is required to provide various external preparations inexpensively in a small and thin form.

As such external agents, various so-called "sheet external agents" in which an external agent is applied to a sheet-shaped substrate and covered with a film have been proposed.
For example, Patent Document 1 describes a method for manufacturing a cosmetic sample, which is a cosmetic sheet provided with a cosmetic (external agent) layer on a part of the surface of a base material sheet to make up makeup The surface of the material layer is exposed to form a protective sheet provided with an opening and a transparent film are laminated. According to Patent Document 1, it is possible to provide a thin and small cosmetic test sample such as a compact and eye shadow at a low cost.

Further, Patent Document 2 describes a cosmetic which can provide a plurality of cosmetic materials such as a powder foundation, an eye shadow, and a lipstick by laminating a plurality of layers of a laminated body composed of a sheet-like substrate, a cosmetic, and a covering sheet. In addition, the combination of each cosmetic material displays specific characters and graphics, thereby improving the temptation.

However, if an oily external preparation containing a large amount of oil component is used as the external preparation contained in the sheet-shaped external preparation, the external preparation is adhered on the side of the film (or sheet) covering the external preparation so that the external preparation can be actually used. If the amount is reduced, or if the agent adheres to the outside of the coating film and stains the fingers or surrounding objects. In addition, there is also a problem that the oil content contained in the external preparation is separated and exuded with time during storage, and the quality, appearance, and usability of the sheet-shaped external preparation are impaired. Therefore, although an oily external preparation has the advantage that it can be widely used in various application sites, there are many problems in providing it in the form of a sheet.

Therefore, in order to avoid such problems, the above-mentioned Patent Document 2 proposes to arrange a protective frame sheet between the sheet-shaped substrate and the coating film, and to provide a gap so that the cosmetic material and the coating film do not directly contact each other. Patent Literatures 3 and 4 and the like also propose a configuration in which a gap is provided between the oily external preparation and the coating film. Further, Patent Document 1 also illustrates a state in which the protective sheet is preventing direct contact between the cosmetic layer and the transparent film layer.
However, if a spacer member such as a protective frame sheet is arranged between the sheet-like base material and the coating film, not only the overall thickness of the sheet-like external preparation is increased, but the usability is impaired due to its volume. There are also problems such as relatively high manufacturing costs due to the increased number of components and the complicated structure.

On the other hand, as another countermeasure for suppressing the adhesion of the oily external agent to the coating film, it is also considered to increase the viscosity of the oily external agent contained therein, so that the oily external agent layer itself becomes hard. However, if the oily external preparation layer is hardened, the finger-applicability of the oily external preparation may be deteriorated, and the ductility may be impaired when applied to the skin. Color development and other issues.

[Problems to be solved by the invention]

An object of the present invention is to provide a sheet-form external preparation which accommodates an oily external preparation capable of coping with various applications, and even if no gap is provided between the coating film and the oily external preparation layer, the oil-based external preparation is not easily attached to It is covered with a film and has excellent finger picking ability with an oily external preparation.
[Technical means to solve the problem]

The present inventors have conducted intensive studies in order to solve the above-mentioned problems, and as a result, have found that by setting the oily external preparation contained in the sheet-shaped external preparation to a specific composition, it is possible to obtain not only a difficulty in adhering to the coating film, but also a finger dipping property. It is also an excellent external preparation in the form of a sheet, thereby completing the present invention.

That is, the present invention provides a sheet-shaped external preparation, which is a sheet-shaped cosmetic having the following structure:
Substrate sheet
An oily external agent layer is formed on at least a portion of the surface of the substrate sheet; and a coating film is laminated to protect the surface of the oily external agent layer; and the oily external agent constituting the oily external agent layer contains:
(A) 5 to 60% by mass of silicone oil, and
(B) The powder component is 3 to 45% by mass, and the hardness of the oily external preparation is 35 to 170 gf.
[Effect of the invention]

By limiting the composition and hardness of the oily external preparation, the sheet-shaped external preparation of the present invention can suppress the adhesion of the oily external preparation to the coating film. On the other hand, the oily external preparation is also excellent in finger picking. In addition, since the oily external preparation itself does not easily adhere to the coating film, it is not necessary to provide a gap between the oily external preparation layer and the coating film in order to avoid adhesion. Therefore, a simple and thin structure in which the oily external agent layer is in direct contact with the coating film can be adopted.

The sheet-form external preparation of the present invention has a simple and thin structure as described above, and thus can be manufactured and provided relatively inexpensively. Therefore, even if multiple sheets are stacked for storage, it does not occupy volume and is excellent in portability. It can be easily purchased and used by a wide range of customers. It is also suitable as a trial product for advertising and is included with magazines or leaflets.
Furthermore, since the sheet-like external preparation of the present invention has good finger-dipability, when the oily external preparation contains a colorant, it exhibits excellent color development when it is applied to the skin or the like. Moreover, when the oily external preparation contains a fragrance | flavor, it shows the effect which is also excellent in the sustainability of an aroma.

The sheet-form external preparation of the present invention includes: a base material sheet; an oily external preparation layer formed on at least a portion of the surface of the base material sheet; and a coating film laminated to protect the surface of the oil-based external preparation layer. Hereinafter, the present invention will be described in detail.

＜ Base material sheet ＞
The substrate sheet is a backing paper for forming an oily external agent layer by coating an oily external agent on a part or the entire surface thereof.
The material of the base material sheet used in the present invention is not particularly limited, and paper, resin sheet, metal sheet, etc. may be used, but in order to avoid the penetration of the oil agent contained in the oily external agent, the oily external agent layer is formed The surface is preferably made of polyester such as PET (polyethylene terephthalate) resin. For example, when a paper substrate is used, it is preferable that at least the surface forming the oily external agent layer is coated or laminated with a PET resin film or the like.

The shape or size of the base material sheet is not particularly limited. For example, a quadrilateral having a side of 2 to 5 cm and a thickness of 100 μm to 500 μm can provide a sheet-like external preparation that does not occupy volume and is also excellent in portability.
In order to prevent the oily external agent layer from slipping or falling off, the surface of the base sheet may be roughened.

＜ Oil-based external agent layer ＞
The oily external agent layer is a solid film containing an oily external agent, which is formed by coating an oily external agent on a part or the entire surface of the base material sheet and drying it.
The oily external preparation can be applied by a known coating method. Especially good for screen printing.
The thickness of the oily external agent layer is preferably 10 to 200 μm, and more preferably 40 to 140 μm. If the thickness of the oily external preparation layer is within this range, the adhesion of the oily external preparation to the coating film can be suppressed, and a sufficient amount of good finger dipability can be provided.

＜ Oil-based external agent ＞
The oily external preparation constituting the oily external preparation layer must contain (A) a silicone oil and (B) a powder component, and the hardness at 25 ° C has a specific numerical range. The so-called oily external preparation in the present invention is a composition containing a large amount of oil ingredients, and can be applied to various parts of the skin that have keratin as the main component, such as the stratum corneum of the skin, hair, and nails. Its application is not particularly limited, and it includes cosmetics such as make-up and cleaning products, or insect repellents or acne care products such as pharmaceuticals, quasi-drugs, and medicinal cosmetics formulated with various active ingredients. In addition, the use pattern is not particularly limited, and includes all patterns such as those applied only to the application site and those that are washed away or wiped off after application.

(A) Silicone oil (A) The silicone oil used in the present invention is a silicone oil generally used in cosmetics, and one or two or more kinds can be arbitrarily selected for use.
Examples of preferred silicone oils include polydimethylsiloxane, trimethylpentaphenyltrisiloxane, diphenylsiloxyphenyl polytrimethylsiloxane, and diphenyl polydisiloxane. Methylsiloxane, (perfluorooctylethyl / diphenylpolydimethylsiloxane) copolymer, and cyclopentasiloxane.
Examples of commercially available silicone oils include KF-96A-6cs, KF-96-100cs, KF-96-300cs, KF-96-1000cs, and KF-96-, which are polydimethylsiloxanes. 5000cs (the above is Shin-Etsu Chemical Industry Co., Ltd.); Methylphenyl silicone PH-1555 as trimethylpentaphenyltrisiloxane (Toray Dow Corning Corporation); as diphenylsilyloxyphenyl polytrimethyl ether Siloxane KF56 (Shin-Etsu Chemical Industry Co., Ltd.); Silicone KF54, Silicone KF-54HV as diphenyl polydimethylsiloxane (Shin-Etsu Chemical Co., Ltd.); FMPS (Japan Momentive Advanced Materials Co., Ltd.) based on ethyl ethyl / diphenyl polydimethylsiloxane; and Execol D-5 (Shin-Etsu Chemical Industry Co., Ltd.) as cyclopentasiloxane.

(A) The blending amount of the silicone oil is 5 to 60% by mass, more preferably 10 to 60% by mass, and still more preferably 10 to 30% by mass relative to all oily external agents. If it is less than 5% by mass, there is a tendency that the adhesion of the oily external preparation to the coating film cannot be suppressed, or sufficient finger dipping or color development cannot be obtained. On the other hand, if it exceeds 60 mass%, penetration may occur during storage.

(B) Powder component The powder component (B) used in the present invention is not particularly limited as long as the powder component can be used in cosmetics, pharmaceuticals, and quasi-drugs. Examples of such powder components include inorganic pigments such as titanium dioxide, zinc oxide, iron oxide, and chromium oxide; pearlescent agents such as titanium oxide-coated mica and titanium oxide-coated borosilicate glass; spherical silicon dioxide and spherical polyethylene Spherical powders such as polyamide spherical resin powder (nylon spherical powder), crosslinked poly (meth) acrylate spherical resin powder, etc .; talc, mica, kaolin, sericite, calcium carbonate, magnesium carbonate, etc. Constitution pigments; and polydimethylsiloxane cross-linked polymers, (polydimethylsiloxane / vinyl polydimethylsiloxane) cross-linked polymers, polymethylsilsesquioxane, etc. Molecular silicone powder and so on.

(B) The blending amount of the powder component is 3 to 45% by mass, and more preferably 4 to 40% by mass, with respect to the entire oily external preparation. If it is less than 3% by mass, it tends to be difficult to suppress the adhesion of the oily external preparation to the coating film. Furthermore, it was surprising that when the oily external preparation contains a fragrance, it was confirmed that if the powder component (B) is blended with 3% by mass or more, an unexpected effect is maintained for a longer time. On the other hand, if the powder component (B) is blended in excess of 45% by mass, there are too many powders to cope with the multipurpose application which is an advantage of an oily external preparation, especially in the case of lips, etc., and there is a noticeable damage to the touch.

Hardness The hardness of the oily external agent at 25 ° C is 35 ~ 170 gf (0.34 ~ 1.67 N), more preferably 40 ~ 150 gf. If the hardness of the oily external agent is less than 35 gf, it is difficult to suppress the adhesion or penetration of the oily external agent to the coating film. On the other hand, if the hardness of the oily external preparation exceeds 170 gf, the wettability of the fingers may be deteriorated due to the excessive hardness, and it may not be applied smoothly. tendency.
Furthermore, in the present invention, the so-called hardness refers to heating and melting the oily external preparation, filling it into a 10 ml ointment pot and curing it, and using a rheometer (pressure sensing shaft 1 f, needle (2 cm / min penetration speed, 10 mm penetration).

As long as the effect of the present invention is not hindered, other components usually formulated in a solid or semi-solid external preparation can be arbitrarily mixed with the oily external preparation. Examples of such other components include oils other than the aforementioned (A) silicone oil, colorants, thickeners, ceramides, vitamins, ultraviolet absorbers, chelating agents, fungicides, preservatives, and amino groups. Lower alcohols such as acids, various chemicals, perfumes, ethanol, etc.

For example, in order to adjust the hardness of an oily external preparation, it is preferable to mix solid oil as an oil component other than (A) silicone oil. As the solid oil component, an oil component which is generally solid to semi-solid at normal temperature and has a melting point of about 50 ° C. or higher among the oil components generally used in cosmetics, and more preferably a melting point of 50 to 90 ° C. can be used. Examples include: solid oils such as wood wax and hydrogenated castor oil; waxes such as carnauba wax, beeswax, candela wax, jojoba wax, etc .: hydrocarbon waxes such as polyethylene wax, paraffin wax, ceresin wax, and microcrystalline wax ; Higher alcohols such as behenyl alcohol, cetyl alcohol, and shark liver alcohol; and silicone wax. Particularly preferred are hydrocarbon waxes such as microcrystalline wax and polyethylene wax in terms of excellent adhesion prevention or penetration prevention to the coating film.

In the case of blending solid oil, the blending amount is 30% by mass or less, more preferably 5 to 30% by mass, and still more preferably 5 to 20% by mass relative to all oily external agents. If the content exceeds 30% by mass, the oily external preparation will become too hard, which will result in poor finger pick-up, and when applied to the skin or lips, there is a tendency that a sufficient color cannot be obtained.

Examples of oils other than solid oils include olive oil, avocado oil, camellia oil, Australian walnut oil, evening primrose oil, jojoba oil, rapeseed oil, egg butter, sesame oil, castor oil, safflower oil, cottonseed oil, Liquid oils such as soybean oil, tea seed oil, rice bran oil, germ oil; hydrocarbon oils such as squalane, liquid paraffin; isocetyl isostearate, cetyl 2-ethylhexanoate, palmitic acid 2- Heptyl undecyl ester, diisobutyl adipate, 2-hexyldecyl sebacate, isopropyl myristate, 2-octyldodecyl oleate, diisostearyl malate Ester, ethylene glycol di-2-ethylhexanoate, glyceryl tri-2-heptyl undecanoate, glyceryl tri-2-ethylhexanoate, glyceryl diisostearate, glycerol triisopropyl Stearate, glyceryl diisostearate, glyceryl tricaprylate, glyceryl triisopalmitate, trimethylolpropane tri-2-ethylhexanoate, pentaerythritol tetra-2-ethylhexanoate Ester oils, etc .; Polydimethylsiloxane, methylphenyl polysiloxane (diphenylsiloxyphenyl polytrimethylsiloxane) and other chain silicone oils; octamethylcyclotetrasiloxane Siloxane, Decamethyl Cyclic silicone oils such as cyclopentasiloxane; and triglycerides, fluorine-modified oils, etc.

Moreover, as a coloring material, the coloring material which does not belong to said (B) powder component, and is a pigment mainly containing an organic compound is preferable. Examples include organic pigments such as zirconium, barium, or aluminum lakes (e.g., red 201, red 202, red 204, red 205, red 220, red 226, red 228, red 405, orange Organic pigments such as 203, orange 204, yellow 205, yellow 401, and blue 404, red 3, red 104, red 106, red 227, red 230, red 401, and red 505 No. 205, Orange No. 4, Yellow No. 5, Yellow No. 202, Yellow No. 203, Green No. 3, Blue No. 1, etc.); and natural pigments (such as chlorophyll, β-carotene, etc.).

As a medicament, for example, vitamin A oil, retinol, retinyl palmitate, pyridoxine hydrochloride, benzyl nicotinate, nicotinamide, dl-α-tocopheryl nicotinate, and ascorbic acid can be formulated. Vitamins such as magnesium phosphate, vitamin D2, dl-α-tocopherol, pantothenic acid, biotin; anti-inflammatory agents such as chamomile and glycyrrhizin; arbutin, 4-methoxysalicylic acid, tranexamic acid, Whitening agents such as ethyl vitamin C and magnesium ascorbate; hormones such as estradiol; astringents such as zinc oxide and tannic acid; cooling agents such as L-menthol and camphor; and chlorinated lysozyme, pyridoxine hydrochloride, sulfur Wait. Furthermore, various extracts exhibiting various medicinal effects can be formulated. That is, extracts of Houttuynia cordata, Cork extract, licorice extract, peony root extract, peony peel extract, loofah extract, saxifraga extract, eucalyptus extract, clove extract, horse chestnut Extract, cornflower extract, seaweed extract, thyme extract, etc.

Furthermore, in the present invention, a dextrin fatty acid ester known as an organic gelling agent should not be formulated into an oily external preparation. When a dextrin fatty acid ester is blended, an oily external preparation layer having an appropriate hardness cannot be formed, and the adhesion to a coating film cannot be sufficiently suppressed. Examples of the dextrin fatty acid ester include Rheopearl series (Chiba Flour Mill).

＜ Coated film ＞
The coating film is a film laminated to protect the oily external agent layer formed on the base material sheet.
The material of the coating film used in the present invention is not particularly limited, and a polyester film, a polyethylene film, a polypropylene film, and a polycarbonate film can be used. Among them, a polyester film is preferred, and a PET resin film is particularly preferred in terms of excellent permeability avoidance of oil in the oily external preparation.
The shape or size of the coating film is not particularly limited as long as it can completely cover the oily external agent layer formed on the base material sheet. For example, the shape and size of the coating film can be the same as the base material sheet.

＜ Method for manufacturing tablet external preparation ＞
Each raw material is melted and mixed to prepare an oily external preparation, and the obtained oily external preparation is coated on a part or the entire surface of a base material sheet and dried according to a known method such as screen printing to form an oily external preparation layer. .
Next, the coating film is laminated so as to cover the oily external agent layer on the base material sheet. Here, in order to prevent the coating film from shifting or falling off, the coating film and the substrate sheet may be peeled off and bonded to the outer peripheral portion of the oily external agent layer by a pressure-sensitive adhesive or the like.
[Example]

The present invention will be described in more detail with specific examples below, but the present invention is not limited to the following examples. In addition, unless otherwise stated, the compounding quantity in the following examples etc. shows the mass%.

(Examples 1 to 13 and Comparative Examples 1 to 14)
On a base material sheet containing a PET resin film having a thickness of 135 to 350 μm, an oily external preparation (cosmetic) having the composition disclosed in Table 1 below is 8 to 20 mg per sheet external preparation. This is done by screen printing into a roughly square shape. It was allowed to dry at room temperature to form an oily external preparation layer having a thickness of 40 to 135 μm. Next, a coating film made of PET resin was coated so as to cover the oily external agent layer, and cut into a sheet-like external agent having a length of 27 mm by 27 mm.
Each of the obtained sheet external agents was evaluated for the following items.

＜ Hardness of oily external agent ＞
In order to find out the hardness of the oily external preparations used to make each sheet of external preparations, the oily external preparations were heated and melted and filled into 10 ml ointment pots respectively, and left to stand at 25 ° C for 1 day. A rheometer (pressure sensing shaft 1 f, penetration speed 2 cm / min, penetration 10 mm) manufactured by Otec was used to measure the hardness at 25 ° C.

＜ Adhesion rate of oily external agent to coating film ＞
Each sheet-form external preparation was arrange | positioned vertically, and it stored at 25 degreeC for 7 days. Next, a finger is brought into contact with one side of the sheet-shaped external preparation, the coating film is lifted, and the coating film is completely peeled from the base material sheet. The amount (adhesion rate) of the oily external preparation adhered to the coating film was evaluated based on the following criteria. Regarding each oily external preparation, 6 pieces of sheet external preparations were evaluated, and the worst evaluation among the 6 pieces was taken as the evaluation result. Judgment and evaluation A to B are qualified.

Evaluation benchmark
A: The weight of the oily external preparation adhered to the coating film is less than 10% of the total amount of the oily external preparation.
B: The weight of the oily external preparation adhered to the coating film is 10% to 30% of the total amount of the oily external preparation
C: The weight of the oily external preparation adhered to the coating is 30% or more and less than 45% of the total amount of the oily external preparation.
D: The weight of the oily external preparation adhered to the coating film is 45% or more and less than 70% of the total amount of the oily external preparation.
E: The weight of the oily external preparation adhered to the coating film is more than 70% of the total amount of the oily external preparation

＜ Ease of finger dipping and good color development ＞
The actual use test of each sheet external preparation was carried out by 10 professional functional inspectors. Specifically, a professional functional inspector is required to actually dip an oily external preparation from the substrate sheet with a finger and apply it to the lips. The finger pickability and color development were judged according to the following criteria. Judgment and evaluation A to B are qualified.
Judgment criteria
A: 9 ~ 10 professional functional inspectors approve the finger picking and good color development.
B: 7 ~ 8 professional sensory inspectors recognized that the finger picking and color development were good.
C: 5 ~ 6 professional inspectors approve the finger picking and good color development.
D: 3 ~ 4 professional functional inspectors approve the finger picking and good color development.
E: Two or less professional functional inspectors recognize that the fingers have good dipability and good color development.

The composition and evaluation results of the oily external preparations used in Examples and Comparative Examples are shown in Tables 1 and 2 below.
