Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a degreasing paper for cosmetics, and more specifically, it is superior in apparent absorbency of skin oil (feeling degreased) and absorbability of true sebum.
The present invention relates to a degreasing paper for cosmetics which has a design property such as a picture and a character and which can clearly confirm that the sebum is removed at the time of use and gives a sufficient satisfaction to the user.

[0002]

2. Description of the Related Art In the human body, the face, especially around the nose, chin, eyebrows, etc., has a large amount of secreted sebum and tends to be oily. In general, cosmetics do not fit well on the skin when makeup is applied with sebum raised. Therefore, makeup is usually applied after removing oil. That is, when the makeup is removed or the makeup is reapplied, the portion where the sebum is raised is pressed by the makeup degreasing paper to absorb the fat from the makeup degreasing paper before applying makeup. In the commercially available degreasing paper for cosmetics that has been conventionally used, papers made of vegetable fibers such as hemp having an oil absorbing property are used. However, the paper made of hemp fiber has a large absorbency of sebum, but since the hemp fiber is relatively hard, it may irritate the skin during use. In order to reduce the irritation to the skin, a strong compression roll press is used during the production of the cosmetic degreasing paper,
For example, the surface of paper is coated with calcium carbonate powder or other inorganic powder. However, when roll-pressing at the time of manufacturing the degreasing paper for cosmetics to crush the fibers constituting the paper, the fibers become napped over time, which gives irritation to the skin. Further, in the case of a cosmetic degreasing paper coated with a calcium carbonate pigment or another inorganic pigment, there is a problem in that the skin oil is not irritated at the time of use, but the ability to absorb sebum is lost. This is because when the inorganic pigment is applied to the paper surface, the inorganic pigment and the adhesive are mixed and applied, and therefore the surface of the coated paper obtained is covered with the pigment and the adhesive having a small sebum absorbency. It is unavoidable that the degreasing effect of cosmetic degreasing paper decreases. In order to solve the above-mentioned problems, the present inventors have previously developed a degreasing paper for cosmetics, which has a high oil-sucking effect and has a significantly low irritation to the skin during use (JP-A-6-319664).
Issue).

[0003]

In the above-mentioned invention of the prior application, it has been confirmed for some time that the sebum was removed by making the paper transparent due to the oil absorbency of the oil removing paper. The present invention is based on the technique of the above-mentioned prior invention, and imparts a design property such as a pattern or a character to the oil removing paper before the oil removal, and as the paper absorbs oil and fat and becomes transparent, the image and the character etc. The purpose of the present invention is to provide a degreasing paper for makeup that can give the user further satisfaction by adding an indicator function so that the oil absorption effect can be more clearly confirmed by disappearance of the oil. It is what

[0004]

Means for Solving the Problems As a result of intensive studies in view of the above situation, the present inventors have used vegetable fibers having excellent sebum absorbability as a raw material for stock, and inorganic pigments having excellent oil absorbency. It has been found that a degreasing paper for cosmetics having a desired performance can be obtained by applying a clarifying agent in the form of a printed pattern such as a picture or a character on the surface of a paper having a specific tenacity used in combination with. The present invention has been completed based on such findings. That is, the present invention prepares a paper stock prepared by mixing (A) 100 parts by weight of a pulp raw material containing a vegetable fiber as a main component with 50 parts by weight or less of (B) an inorganic filler, and making a papermaking paper. Provided is a degreasing paper for makeup, which is obtained by applying a clarifying agent to a part of at least one surface of a paper having a degree of 0.6 or more.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION First, in the present invention, the pulp raw material of the component (A), which is used to prepare a paper material for making a degreasing paper for cosmetics, contains vegetable fiber as a main component, It is composed of this and at least one selected from wood pulp, polyolefin synthetic pulp and synthetic fiber. Here, various kinds of plant fibers can be mentioned, for example, Manila hemp, flax, cannabis, jute, mulberry, honey or bast fiber made of pelt, cotton, cotton such as cotton linter, and others, straw, bamboo , Esparto, bagasse, kenaf, etc. can be used.

[0006] These plant fibers are, of course, pulped by various pulping methods commonly used in the pulp manufacturing method, for example, chemical pulping methods such as Kraft method, soda method and sulfurous acid method, and other known pulping methods. It is taken out and used as a fiber. These plant fibers may be used alone or in a mixture of two or more kinds. Among these, vegetable fibers from Manila hemp are preferably used from the viewpoints of absorbency of sebum, availability, supply amount and the like. Then, this vegetable fiber is used in the preparation of a paper material so as to be blended with at least 50% by weight, preferably 70% by weight or more, relative to other pulp raw materials.

Next, in the preparation of the stock material for the degreasing paper for cosmetics, the pulp raw material of the component (A) includes not only plant fibers but also wood pulp and polyolefin synthetic materials commonly used in the papermaking industry. At least one selected from pulp and synthetic fibers can be used. As the wood pulp, wood pulp produced from a softwood, a hardwood, etc. by a chemical pulping method such as a kraft method, a soda method, a sulfurous acid method or the like, and other known pulping methods can be used. Also, as the polyolefin synthetic pulp,
Those manufactured by various methods developed by many synthetic resin manufacturers can be used. Here, as the polyolefin, synthetic pulp such as polyethylene and polypropylene is suitable, and the supplyability to the market,
Polyethylene synthetic pulp is most suitable because of its homogeneity and availability.

[0008] For example, polyethylene synthetic pulp "SWP" (manufactured by Mitsui Chemicals, Inc.) is a typical one which is commercially available at present and can be easily obtained. As the synthetic fiber, one generally used in the production of chemical fiber paper, that is, a resin obtained by spinning a raw material resin of synthetic fiber by any method such as a wet method, a dry method, a melting method, etc., has an appropriately short length. Any of those cut into fibers can be used. Specifically, fibers such as polyethylene, polypropylene, polystyrene, polyvinyl chloride, polyvinyl alcohol, acrylic, polyester, nylon, rayon, or a composite fiber having a polyethylene core and a polypropylene sheath-sheath structure, ethylene.
Examples thereof include vinyl acetate copolymer fiber.

In order to improve the dispersibility in water, these synthetic fibers are prepared by subjecting a hydrophobic fiber surface to hydrophilic treatment beforehand, or branched (fibrillated) like plant fibers.
The processed one is used. Among these, for example,
The polypropylene fiber is a fiber obtained by melt-spinning an isotactic polymer obtained by polymerizing propylene with a Ziegler type catalyst, and cutting the fiber into a desired length. The polypropylene fiber thus obtained has a specific gravity of 0.
The melting point is 9 to 0.92, the melting point is 164 to 170 ° C, and the softening point is about 150 ° C. The fiber length of these synthetic fibers is usually 0.5 to 30 mm, and generally the one having a fiber length of about 3 to 6 mm is most often used. In the present invention, the polyolefin synthetic pulp and the synthetic fiber are effective in imparting true oil absorbency and flexibility to the degreasing paper for cosmetics.

The above-mentioned polyolefin synthetic pulp is melted by heat treatment, and the polyolefin synthetic pulp is
Alternatively, it is possible to obtain a paper-like sheet by heat-bonding and fixing a polyolefin synthetic pulp and a synthetic fiber to each other, or heat-bonding and fixing a polyolefin synthetic pulp to a synthetic fiber. Of course, it can be used in the same manner as ordinary pulp without heat treatment. In the case of heat treatment, the heat treatment temperature of the polyolefin synthetic pulp is preferably 150 ° C or lower. Further, the above synthetic fibers have a high lipophilicity and also have a heat-bonding property. Therefore, by using these by controlling the kind and the compounding ratio, it is possible to make them soft and lipophilic for cosmetic degreasing. You can get the paper. These wood pulps, polyolefin synthetic pulps or synthetic fibers may be used alone or in combination of two or more. And, the usage amount is 50% by weight or less with respect to the vegetable fiber,
It is preferably used in an amount of 5 to 50% by weight, particularly preferably 5 to 30% by weight.

It is used for the degreasing paper for cosmetics of the present invention (B)
As the inorganic filler of the component, it is possible to use one having an excellent oil absorbing property which is effective for enhancing the oil absorbing property of the cosmetic degreasing paper. For example, as the natural filler, clay, talc, kaolin or the like which is inexpensive and effective for imparting chemical resistance and smoothness can be used. As the artificial filler, calcium carbonate, titanium oxide, white carbon, etc., which are effective in imparting high whiteness and opacity, can be used. These inorganic fillers clogging the gaps between the fibers to impart opacity to the paper, increase the density of the paper, and smooth the paper surface. As a result, the absorption of sebum is improved,
It also has the effect of softening the paper quality.

There are no particular restrictions on the shape of these inorganic fillers, and various types such as granular, tension, spindle-shaped, plate-shaped, and amorphous can be used, and the particle size can be varied in terms of gloss and paper flexibility. Since it is related to the quality and the smoothness of the paper surface,
Usually, those having a thickness of 3 μm or less are preferably used. And when it is necessary to color, for example, red iron oxide,
Ultramarine blue, various iron oxides, etc. may be used in appropriate amounts, and finer particles are preferable. In the preparation of the stock material for the degreasing paper for cosmetics, the inorganic filler of the component (B) is 5 parts by weight per 100 parts by weight of the pulp material of the component (A).
It is mixed in the range of 50 parts by weight. If the amount is less than 5 parts by weight, the effect of improving sebum absorbability is not so noticeable. On the other hand, if it exceeds 50 parts by weight, the strength is lowered and it is not preferable in practical use.

The degreasing paper for cosmetics of the present invention is characterized in that a clarifying agent is applied to at least one surface of the degreasing paper having the above composition, and preferably to a part of one surface. As the clarifying agent that can be used in the present invention,
It is preferable that the printed part coated with the clarifying agent has the same color as the non-printed part made transparent by the oil-absorbing paper for cosmetics absorbing skin oil, for example, a petroleum hydrocarbon resin or the petroleum hydrocarbon resin. Paraffin wax, saturated hydrocarbons such as isoparaffin, rapeseed oil, soybean oil, beef tallow fatty acid animal and vegetable oils, stearic acid, phthalic anhydride, tetrahydrophthalic anhydride, isophthalic acid, terephthalic acid, trimellitic acid, pyromellitic acid, etc. The thing which mix | blended 1 type or 2 types or more of saturated or unsaturated fatty acid can be mentioned. Here, petroleum-based hydrocarbon resins include alicyclic saturated hydrocarbons such as 1,4-bis (hydroxymethyl) cyclohexane and 2,2′-di (4-hydroxyphenyl) propane, and aromatic unsaturated hydrocarbons. The obtained resin and other resins having various substituents such as amino group, hydroxyl group, vinyl group, nitro group and carbonyl group are meant. In addition, substances known to have a refractive index almost equal to that of cellulose, such as liquid paraffin, polybutene, dioctyl phthalate, tricresyl phosphate, phenol resin, urea resin, and melamine, which are known as general clarifying agents. Resin, alkyd resin, epoxy resin, styrene maleic anhydride copolymer, thermosetting resin such as polystyrene resin, unsaturated polyester resin, unsaturated alkyd resin, modified acrylic resin, modified epoxy resin, modified urethane resin, etc., Examples thereof include an ultraviolet curable resin containing an appropriate vinyl monomer and a photosensitizing substance, and a resin containing an olefin polymerized oil as a main component. Among these clarifying agents, a petroleum-based hydrocarbon resin or a mixture of the petroleum-based hydrocarbon resin with one or more of saturated hydrocarbons, animal and vegetable oils, saturated or unsaturated fatty acids is preferably used. it can. The clarifying agent can be applied on a greasing paper in the form of a coating solution diluted with a suitable solvent,
The concentration in the coating liquid is generally 1 to 30% by weight. Examples of the solvent include alcohols such as toluene, water and isopropyl alcohol, but the solvent is not limited to these, and an appropriate solvent can be selected and used according to the type of the clarifying agent. Further, the coating liquid containing a clarifying agent, for the purpose of giving an additional function, an aromatic agent such as jasmine, mint, rosemary, a deodorant such as catechin which is an extract of tea, titanium oxide, etc. An appropriate amount of antibacterial agent or the like can be added.

It is sufficient for such a clarifying agent to be applied to at least a part of the surface of the paper, and the application area is appropriately determined from the viewpoint of the balance thereof within the range where the oil absorbency of the degreasing paper is not impaired. For example, 10% or less of the total area of the greasing paper is suitable. The amount of the clarifying agent applied to the applied portion of the oil-cleaning paper for cosmetics of the present invention is preferably 10 g / m ² or less. If the coating amount is more than 10 g / m ² , the original oil-and-oil property of the degreasing paper itself may be impaired. From this point, the coating amount of the clarifying agent is more preferably 5 g / m ² or less. The coating method is not particularly limited, and for example, any conventionally known printing method such as gravure printing, flexo printing, letterpress printing, and a coating machine such as a roll coater can be used. After applying the coating solution containing the clarifying agent, the coating is dried to complete the application.
