Description

TECHNICAL FIELD The present invention relates to a sheet-like external preparation in which an oil-based external preparation is coated on a base sheet and protected with a coating film. The sheet-like external preparation of the present invention is suitable for containing an oil-based external preparation that can be applied to various sites containing keratin as a main component, such as the stratum corneum of the skin, hair, and nails. It does not easily adhere to the film side, and it is also excellent for finger removal of oil-based external preparations.

In recent years, through fashion magazines, the Internet, etc., awareness of makeup and beauty has spread to younger generations, especially teenagers, and demand for low-priced cosmetics that even children can easily purchase is increasing. Among them, small and thin ones that can be used up in a single use are not bulky even with a wide variety of variations and are highly portable, so they have the potential as new communication tools that can be exchanged with friends or given as gifts. is also hidden. In addition, at various recitals and events, there are more opportunities to challenge bold makeup that is different from usual, and it is required to have a wide range of cosmetics in various colors to complete the makeup as imagined. For this reason, disposable type make-up cosmetics that are rich in color variations and available at low cost are attractive not only to young people but also to adults.

In addition, external agents other than makeup, such as skin, hair, nail care, cleansing, and insect repellent, are small and thin, so they are not bulky and are highly portable, so they can be used when going out. This is especially convenient when traveling. Furthermore, the single-use type is excellent in terms of hygiene because it is used immediately after opening.
As described above, there is a demand to provide various external preparations in a small and thin form at a low cost regardless of user groups and applications.

As such an external preparation, many so-called "sheet-shaped preparations for external use" have been proposed, in which a sheet-shaped base material is coated with the preparation for external use and covered with a film.
For example, in Patent Document 1, a cosmetic sheet having a cosmetic (external agent) layer provided on a part of the surface of a base sheet, a protective sheet provided with an opening so that the surface of the cosmetic layer is exposed, A method for manufacturing a cosmetic sample laminated with a transparent film layer is described. According to Patent Document 1, it is possible to provide thin and compact cosmetic samples such as foundations and eye shadows at low cost.

Further, in Patent Document 2, a combination of multiple cosmetics such as foundation, eye shadow, and lipstick can be provided at the same time by stacking a plurality of laminates each composed of a sheet-like base material, cosmetics, and a coating sheet. , describes cosmetics that are said to enhance appeal by expressing predetermined letters and figures in cooperation with each other.

However, if an oil-based topical preparation containing a large amount of oil component is used as a topical preparation contained in a sheet-shaped topical preparation, the topical preparation will adhere to the film (or sheet) that covers the topical preparation, making it difficult to actually use the topical preparation. The amount of external preparation that can be applied may decrease, and the external preparation attached to the coating film may stain fingers and surrounding objects. In addition, there is also the problem that the oil contained in the topical preparation separates over time and oozes out during storage, impairing the quality, appearance, and usability of the sheet-like topical preparation. Therefore, although oily external preparations have the advantage of being widely applicable to various areas of application, there have been many problems in providing them in the form of sheets.

Therefore, in order to avoid such a problem, in Patent Document 2, a protective frame sheet is arranged between the sheet-like substrate and the covering film so that the cosmetics and the covering film do not come into direct contact. It is proposed to provide a gap. Similarly, a configuration in which a gap is provided between an oily external preparation and a coating film has been proposed in many documents such as Patent Documents 3 and 4. Furthermore, Patent Document 1 also illustrates a mode in which a protective sheet prevents 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 covering film, the thickness of the entire sheet-like external preparation is increased, making it bulky and impairing the handleability, and the member is also bulky. There is a problem that the manufacturing cost becomes relatively high due to the increase in number and the complexity of the structure.

On the other hand, as another measure for suppressing adhesion of the oil-based external preparation to the coating film, it is conceivable to increase the viscosity of the contained oil-based external preparation to harden the oil-based topical preparation layer itself. However, when the oil-based external preparation layer becomes hard, the oil-based external preparation is not easy to pick up with fingers, and spreadability when applied to the skin is impaired. There is a problem that color development cannot be obtained.

JP-A-2002-58528 JP 2017-29589 A JP-A-2000-287748 JP-A-2000-139558

The present invention is a sheet-like external preparation containing an oil-based external preparation that can be used in multiple applications, wherein the oil-based topical preparation adheres to the covering film without providing a gap between the covering film and the oil-based topical preparation layer. To provide a sheet-like preparation for external use which is difficult to remove and is excellent in finger removal of an oil-based preparation for external use.

As a result of intensive research to solve the above-mentioned problems, the present inventors found that by making the oil-based external preparation contained in the sheet-shaped external preparation have a specific composition, it is difficult to adhere to the coating film, but it is easy to use on the finger. The present inventors have found that a sheet-like preparation for external use that is excellent in removal can be obtained, and have completed the present invention.

That is, the present invention
a base sheet;
an oil-based external agent layer formed on at least part of the surface of the base sheet;
A sheet-like cosmetic comprising a coating film laminated so as to protect the surface of the oily external agent layer,
The oil-based external agent that constitutes the oil-based external agent layer is
(A) 5 to 60% by mass of silicone oil, and (B) 3 to 45% by mass of powder component,
and the hardness of the oily external preparation is 35 to 170 gf.

By limiting the composition and hardness of the oil-based external preparation, the sheet-like external preparation according to the present invention can suppress the adhesion of the oil-based topical preparation to the coating film, and is also excellent in finger removal of the oil-based topical preparation. In addition, since the oil-based external preparation itself has the property of being difficult to adhere to the coating film, it is not necessary to provide a gap between the oil-based external preparation layer and the coating film in order to avoid adhesion. Therefore, a simple and thin structure in which the oily external preparation layer and the covering film are in direct contact can be achieved.

Since the sheet-like external preparation according to the present invention has a simple and thin structure as described above, it can be manufactured and provided at a relatively low cost. Therefore, even if multiple sheets are stacked and stored, they are not bulky and are excellent in portability, so that a wide range of consumers can easily purchase and use them. It is also suitable for attachment to magazines and leaflets as a sample for advertisement.
Furthermore, since the sheet-like external preparation according to the present invention is easy to remove with fingers, when the oil-based external preparation contains a coloring material, it exhibits excellent color development when applied to the skin or the like. In addition, when the oil-based external preparation contains a perfume, it exhibits an excellent effect in terms of persistence of the scent.

The sheet-like topical preparation of the present invention comprises a base sheet, an oil-based topical preparation layer formed on at least a part of the surface of the base sheet, and a coating film laminated so as to protect the surface of the oil-based topical preparation layer. have The present invention will be described in detail below.

<Base material sheet>
The base sheet is a mount for forming an oil-based external agent layer by applying an oil-based external agent to a part or the entire surface of the base sheet.
The material of the base sheet used in the present invention is not particularly limited, and paper, resin sheets, metal sheets, etc. can be used. For this reason, it is preferable that the surface forming the oily external agent layer is 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 outer shape and dimensions of the base sheet are not particularly limited. For example, a quadrilateral having a length and width of 2 to 5 cm and a thickness of 100 to 500 μm is preferable because it is not bulky and can provide a sheet-like external preparation excellent in portability.
The surface of the base sheet on which the oily external agent layer is to be formed may be roughened in order to prevent the oily external agent layer from slipping or falling off.

<Oil-based external agent layer>
The oil-based external agent layer is a solid thin film made of an oil-based external agent, which is formed by applying the oil-based external agent to a part or the entire surface of the base sheet and drying it.
A known application method can be used to apply the oily external preparation. Especially preferred is screen printing.
The thickness of the oily external preparation layer is preferably 10-200 μm, more preferably 40-140 μm. If the thickness of the oil-based external preparation layer is within this range, it is possible to supply a sufficient amount of the oil-based preparation for good finger-removability while suppressing adhesion of the oil-based external preparation to the coating film.

<Oil-based topical agent>
The oily external preparation constituting the oily external preparation layer essentially contains (A) a silicone oil and (B) a powder component, and has a specific numerical range of hardness at 25°C. In the present invention, an oil-based external preparation is a composition containing a large amount of an oil component and can be applied to various sites containing keratin as a main component, such as the stratum corneum of the skin, hair, and nails. Its use is not particularly limited, and includes cosmetics such as make-up and cleansing, pharmaceuticals containing various active ingredients such as insect repellent and acne care, quasi-drugs, and medicinal cosmetics. In addition, the mode of use is not particularly limited, and includes all modes such as simple application to the application site, washing off after application, and wiping off.

(A) Silicone oil The (A) silicone oil used in the present invention is a silicone oil that is commonly used in cosmetics, and one or more of them can be arbitrarily selected and used.
Preferred silicone oils include dimethicone, trimethylpentaphenyltrisiloxane, diphenylsiloxyphenyltrimethicone, diphenyldimethicone, (perfluorooctylethyl/diphenyldimethicone) copolymer, cyclopentasiloxane, and the like.
Commercial products of silicone oil include, for example, dimethicone KF-96A-6cs, KF-96-100cs, KF-96-300cs, KF-96-1000cs, KF-96-5000cs (Shin-Etsu Chemical Co., Ltd.) , methylphenyl silicone PH-1555 (Dow Corning Toray Co., Ltd.) which is trimethylpentaphenyltrisiloxane, silicone KF56 (Shin-Etsu Chemical Co., Ltd.) which is diphenylsiloxyphenyl trimethicone, silicone KF54 which is diphenyl dimethicone, silicone KF-54HV ( Above, Shin-Etsu Chemical Co., Ltd.), FMPS (Momentive Performance Materials Japan LLC), a (perfluorooctylethyl/diphenyl dimethicone) copolymer, and Execol D-5, a cyclopentasiloxane (Shin-Etsu Chemical Co., Ltd.). can be mentioned.

(A) The amount of silicone oil to be blended is 5 to 60% by mass, more preferably 10 to 60% by mass, and still more preferably 10 to 30% by mass, based on the total oily external preparation. If it is less than 5% by mass, the adhesion of the oil-based external preparation to the coating film cannot be suppressed, and there is a tendency that sufficient finger removal and color development cannot be obtained. On the other hand, if the content exceeds 60% by mass, bleeding may occur during storage.

(B) Powder component The powder component (B) used in the present invention is not particularly limited as long as it can be used for 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 silica, spherical polyethylene, and spherical polyamide. Spherical powders such as resin powder (nylon spherical powder), crosslinked poly(meth)acrylate spherical resin powder; extender pigments such as talc, mica, kaolin, sericite, calcium carbonate, magnesium carbonate; dimethicone crosspolymer, (dimethicone /vinyl dimethicone) crosspolymer, polymer silicone powder such as polymethylsilsesquioxane, and the like.

The blending amount of the powder component (B) is 3 to 45% by mass, more preferably 4 to 40% by mass, relative to the total oily external preparation. If it is less than 3% by mass, it tends to be difficult to prevent the oily external preparation from adhering to the coating film. Surprisingly, it has been confirmed that when the oily external preparation contains a fragrance and the powder component (B) is blended in an amount of 3% by mass or more, the fragrance lasts for a longer period of time, which is an unexpected effect. On the other hand, if the powder component (B) is blended in an amount exceeding 45% by mass, the amount of powder is too much and the multi-use, which is an advantage of oil-based external preparations, cannot be achieved, and the feeling of use is significantly impaired, especially when applied to the lips. .

Hardness The hardness of the oily external preparation at 25°C is 35 to 170 gf (0.34 to 1.67 N), more preferably 40 to 150 gf. When the hardness of the oil-based external preparation is less than 35 gf, it tends to be difficult to prevent the oil-based external preparation from adhering to the coating film and bleeding. On the other hand, when the hardness of the oil-based external preparation exceeds 170 gf, the hardness is too high and the finger-removing preparation is difficult to apply smoothly.
The hardness in the present invention is defined by heating and dissolving an oily external preparation, filling it in a 10 ml ointment bottle and solidifying it, and measuring it at 25° C. with a rheometer manufactured by Rheotech (pressure sensitive axis 1φ, penetration speed 2 cm/min, It is a value measured with a penetration of 10 mm).

The oil-based external preparation may optionally contain other components that are usually blended in solid or semi-solid external preparations as long as they do not impair the effects of the present invention. Examples of such components include (A) oils other than silicone oil, coloring materials, thickeners, ceramides, vitamins, ultraviolet absorbers, chelating agents, bactericides, preservatives, amino acids, various drugs, Perfumes, lower alcohols such as ethanol, and the like can be mentioned.

For example, (A) as an oil other than silicone oil, it is preferable to add a solid oil to adjust the hardness of the oily external preparation. As the solid oil, among the oils commonly used in cosmetics, those that are solid to semi-solid at room temperature and have a melting point of about 50°C or higher, more preferably 50 to 90°C. can be used. Solid oils and fats such as Japanese wax and hydrogenated castor oil; Waxes such as carnauba wax, beeswax, candelilla wax and jojoba wax; Hydrocarbon waxes such as polyethylene wax, paraffin wax, ceresin and microcrystalline wax; Behenyl alcohol, cetanol and batyl alcohol higher alcohols such as; silicon wax; and the like. In particular, hydrocarbon waxes such as microcrystalline wax and polyethylene wax are preferable because they are excellent in preventing adhesion to the coating film and preventing bleeding.

When solid oil is blended, 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, based on the total oily external preparation. If the amount exceeds 30% by mass, the oily external preparation will become too hard and will not be easy to pick up on the fingers, and there is a tendency that sufficient color development cannot be obtained when applied to the skin or lips.

Oils other than solid oils include olive oil, avocado oil, camellia oil, macadamia nut oil, evening primrose oil, jojoba oil, rapeseed oil, egg yolk oil, sesame oil, castor oil, safflower oil, cottonseed oil, soybean oil, teaseed oil, and rice bran. Liquid fats and oils such as oils and germ oils; Hydrocarbon oils such as squalane and liquid paraffin; Isopropyl myristate, 2-octyldodecyl oleate, diisostearyl malate, ethylene glycol di-2-ethylhexanoate, glyceryl tri-2-heptylundecanoate, glyceryl tri-2-ethylhexanoate, glyceryl diisostearate , glyceryl triisostearate, glyceryl diisostearate, glyceryl trioctanoate, glyceryl triisopalmitate, trimethylolpropane tri-2-ethylhexanoate, pentaerythritol tetra-2-ethylhexanoate; dimethyl polysiloxane , chain silicone oils such as methylphenylpolysiloxane (diphenylsiloxyphenyltrimethicone); cyclic silicone oils such as octamethylcyclotetrasiloxane and decamethylcyclopentasiloxane; triglycerin and fluorine-modified oils.

As the colorant, a colorant not corresponding to the powder component (B) above, and a pigment mainly composed of an organic compound is preferable. For example, organic pigments such as zirconium, barium or aluminum lakes (e.g. Red No. 201, Red No. 202, Red No. 204, Red No. 205, Red No. 220, Red No. 226, Red No. 228, Red No. 405, Orange No. 203 , Orange 204, Yellow 205, Yellow 401, and Blue 404, Red 3, Red 104, Red 106, Red 227, Red 230, Red 401, Red 505, Orange No. 205, Yellow No. 4, Yellow No. 5, Yellow No. 202, Yellow No. 203, Green No. 3 and Blue No. 1); natural pigments (eg, chlorophyll, β-carotene, etc.);

Examples of drugs include vitamin A oil, retinol, retinol palmitate, pyridoxine hydrochloride, benzyl nicotinate, nicotinamide, dl-α-tocopherol nicotinate, magnesium ascorbate phosphate, vitamin D2, dl-α-tocopherol, Vitamins such as pantothenic acid and biotin; anti-inflammatory agents such as azulene and glycyrrhizin; whitening agents such as arbutin, 4-methoxysalicylic acid, tranexamic acid, ethyl vitamin C, magnesium ascorbate phosphate, hormones such as estradiol; zinc oxide , astringents such as tannic acid; cooling agents such as L-menthol and camphor; lysozyme chloride, pyridoxine hydrochloride, sulfur and the like. Furthermore, various extracts exhibiting various medicinal effects can be blended. That is, Houttuynia cordata extract, Phellodendron bark extract, Glycyrrhiza extract, Peony extract, Botanpi extract, Loofah extract, Saxifrage extract, Eucalyptus extract, Clove extract, Horse chestnut extract, Cornflower extract, Seaweed extract, Thyme extract and the like can be mentioned.

In the present invention, dextrin fatty acid ester known as an organogelling agent should not be added to the oily external preparation. When a dextrin fatty acid ester is blended, it becomes impossible to form an oily external preparation layer with appropriate hardness, and there is a tendency that adhesion to the coating film cannot be sufficiently suppressed. Examples of dextrin fatty acid esters include Rheopearl series (Chiba Flour Mills Co., Ltd.).

<Coating film>
The covering film is a film laminated to protect the oily external preparation layer formed on the base sheet.
The material of the covering film used in the present invention is not particularly limited, and polyester film, polyethylene film, polypropylene film and polycarbonate film can be used. Among them, a polyester film is preferable, and a PET resin film is particularly preferable, because it is excellent in preventing permeation of oil in an oily external preparation.
The outer shape and dimensions of the covering film are not particularly limited as long as they can completely cover the oil-based external agent layer formed on the base sheet, and for example, they can have the same shape and dimensions as those of the base sheet.

<Manufacturing method of sheet-like external preparation>
An oil-based external preparation is prepared by dissolving and mixing each raw material, and the obtained oil-based external preparation is applied to a part or the entire surface of a base sheet according to a known method such as screen printing, and dried to obtain an oil-based preparation for external use. form a layer.
Next, a coating film is laminated so as to cover the oily external preparation layer on the base sheet. Here, in order to prevent the covering film from slipping or coming off, the covering film and the base sheet may be releasably adhered to each other at the peripheral edge portion outside the oily external agent layer with a pressure-sensitive adhesive or the like.

EXAMPLES The present invention will be described in more detail below with specific examples, but the present invention is not limited to the following examples. In addition, unless otherwise specified, the blending amounts in the following examples and the like are shown in % by mass.

(Examples 1 to 13 and Comparative Examples 1 to 14)
On a base sheet made of a PET resin film having a thickness of 135 to 350 μm, an oil-based external preparation (cosmetics) having the composition shown in Table 1 below is applied in a substantially square shape so that each sheet-shaped preparation for external use contains 8 to 20 mg. was applied by screen printing. This was dried at room temperature to form an oily external agent layer with a thickness of 40 to 135 μm. Next, a film made of PET resin was put on the layer of the oil-based external preparation, and the film was cut to prepare a sheet-shaped external preparation of 27 mm long and 27 mm wide.
The following items were evaluated for each sheet-shaped external preparation obtained.

<Hardness of Oily External Agent>
In order to examine the hardness of the oil-based external preparation used to prepare each sheet-like external preparation, the oil-based external preparation was heated and dissolved, filled in a 10 ml ointment bottle, and allowed to stand at 25° C. for 1 day to solidify. Later, the hardness at 25° C. was measured with a rheometer manufactured by Rheotech (pressure-sensitive axis 1φ, penetration speed 2 cm/min, penetration 10 mm).

<Attachment rate of oil-based topical agent to coating film>
Each sheet-shaped external preparation was placed vertically and stored at 25° C. for 7 days. Then, the coating film was rolled up by touching one side of the sheet-shaped external preparation with a finger, and the coating film was completely peeled off from the base sheet. The amount (adhesion rate) of the oily external preparation adhering to the coated film was evaluated according to the following criteria. For each oil-based external preparation, 6 sheet-like external preparations were evaluated, and the one with the worst evaluation among the 6 sheets was taken as the evaluation result. Evaluations A to B were judged to be acceptable.

Evaluation Criteria A: The weight of the oily external preparation attached to the coating film is less than 10% of the total amount of the oily topical preparation B: The weight of the oily topical preparation adhering to the coating film is 10% or more and less than 30% of the total weight of the oily topical preparation C : The weight of the oil-based external preparation attached to the coating film is 30% or more and less than 45% of the total amount of the oil-based topical preparation D: The weight of the oil-based topical preparation adhering to the coating film is 45% or more and less than 70% of the total amount of the oil-based topical preparation E : The weight of the oil-based topical preparation adhering to the coating film is 70% or more of the total amount of the oil-based topical preparation.

<Ease of finger picking, good color development>
An actual use test was conducted by 10 expert panels for each sheet-like external preparation. Specifically, a panel of specialists was asked to actually pick up the oil-based external preparation from the base sheet with their fingers and apply it to the lips. Finger removal and good color development were evaluated according to the following criteria. Evaluations A to B were judged to be acceptable.
Judgment Criteria A: 9 to 10 panelists recognized good finger removal and good color development.
B: 7-8 expert panelists recognized good finger removal and color development.
C: 5 to 6 panelists recognized good finger removal and good color development.
D: 3 to 4 panelists recognized good finger removal and color development.
E: Not more than 2 panelists recognized good finger removal and color development.
