DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a grease-removing film used to wipe off sebum and sweat secreted on the surface of the skin and suppressing the influence on the environment at the time of disposal.

[0002]

2. Description of the Related Art Conventionally, as a material used for wiping sebum and sweat secreted from the skin surface, a nonwoven fabric impregnated with a drug, a grease-absorbing paper, and a sebum-absorbing sheet using a porous film are known. ing. The non-woven fabric impregnated with the drug can sufficiently remove the sebum on the face. However, when used by women, there is a drawback that not only the sebum on the face but also the foundation is wiped off.

[0003] The fat-removing paper is similar to the foil stamping paper used when extending gold foil, and is used for ganpi, sampi, pulp,
Honey is also produced by adding an inorganic filler such as mud to plant fibers such as Manila hemp and animal fibers such as silk fibers. Further, a combination of vegetable fiber pulp and an inorganic filler has been devised so that when sebum is absorbed, the part that absorbs sebum is clearly distinguished from other parts.
However, because the need to increase the number of production of fat-removing paper, the amount of effort required to remove sebum compared to foil-pressed paper is less than that of foil-printed paper manufactured by many processes. However, there are disadvantages that the absorption effect of sebum is reduced and the paper is broken during several wiping operations.

On the other hand, the sebum-absorbing sheet has an advantage in that the above-described nonwoven fabric is impregnated with a drug and used, and the disadvantages of fat-absorbing paper are eliminated. The sebum-absorbing sheet contains an olefin-based resin such as polypropylene or low-density polyethylene having a porous structure and a filler such as an inorganic substance such as clay or calcium carbonate or a liquid hydrocarbon-based polymer. In this sebum absorbing sheet, since the resin film absorbs only sebum without absorbing sweat due to water impermeability, there is no decrease in strength or tearing, so that it can be used a plurality of times.

[0005]

However, in the above-mentioned conventional sebum absorbing sheet, since a water-impermeable resin film is used, the sweat cannot be wiped off. Therefore, the sweat must be wiped off with a handkerchief or the like. There was a point. In addition, there is a problem that harmful gas is generated when the used resin film is disposable, when it is incinerated as waste, or when it is left on a roadside or the like, it is almost permanently intact. There was also a problem that it remained in a state.

The present invention has been made in view of the above circumstances, and an object of the present invention is to wipe out sebum and sweat secreted on the surface of the skin such as the face and to determine the effect on the environment when disposed after use. An object of the present invention is to provide a grease removing film that is kept low.

[0007]

It is also possible to make the film easy to use.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, a grease removing film of the present invention and a method for producing the same will be described in detail.

The degreasing film according to the present invention comprises a polyolefin resin or a crystalline resin, vinyl acetate (EVA) and a biodegradable plastic as main components for forming the film, and further comprises an inorganic filler, a water-absorbing polymer, and The pigment is mixed to absorb sebum and sweat and to color the film.

Polyolefin resins include polyethylene, polypropylene and the like, and crystalline resins include polyester, polyethylene glycol, polyethylene terephthalate and the like.

[0011] Vinyl acetate is mixed to soften the synthesized degreasing film.

As the biodegradable plastic, those having plant starch as a main component can be used, and more specifically, those having corn corn starch as a main component and developed by Warner Lambert, Degra Novon (trade name) sold by Novon Japan Co., Ltd. can be used. Degra Novon contains corn corn starch, as well as an auto-oxidation catalyst and a binder resin.

As the inorganic filler, calcium carbonate, barium sulfate, silica, silicon, talc, kaolin, zinc oxide, alumina, magnesium hydroxide and the like can be used. These substances are mixed into the film to roughen the surface of the film.

The water-absorbing polymer is preferably a polyacrylate-based water-absorbing polymer. The water-absorbing polymer is preferably mixed as a raw material of the fat-removing film of the present invention in order to absorb sweat, but need not be mixed as a raw material.

As the pigments, oxides of zirconium, cerium or zinc, chromium oxide, iron oxides of black, yellow, red and brown, manganese violet, ultramarine blue,
Combination of titanium oxide with one selected from iron blue, chromium hydrate, metal oxide of silver powder or aluminum powder, carbon black, phthalocyanine blue, phthalocyanine green, azo pigment or cyan pigment, etc. Can be. Here, the reason for mixing the titanium oxide is to impart hiding power, eliminate the transparency of the film, and visualize the change in the color of the film when sebum is absorbed.

[0016] To prepare the degreasing film of the present invention,
55-70wt of polyolefin resin or crystalline resin
%, Vinyl acetate: 5 to 15 wt%, biodegradable plastic containing corn starch as a main component, degra novon (trade name): 20 to 30 wt%, inorganic filler such as calcium carbonate, 5 to 30 wt%, water absorbing polymer 1 to 10 wt% of a polyacrylic acid, and 0.5 to 1
It is preferable that each raw material is blended at a ratio of 0 wt%.
The raw materials blended in these ratios are stirred by a stirrer, and each raw material is uniformly mixed. At this time,
Since frictional heat generated by stirring causes softening of the material and adversely affects uniform stirring, it is desirable not to use a blender, a mixer, or the like.

The shape of the fat removing film according to the present invention is not particularly limited, and may be any size that can be held by hand and that is easy to use. For example, it may be in the form of a sheet as shown in FIG. 1, may be in the form of a bag as shown in FIG. 2, or may be in the form of a cylinder as shown in FIG. FIG.
3, the three ends of the film 1 are sealed by heat welding as heat-sealed portions 2, and the ends of both sides of the film 1 are heat-sealed portions 2 in a cylindrical shape shown in FIG. The grease-removing film is made easy to hold by sealing by welding so that a finger can be inserted into a bag or a tube. When a finger is inserted into the tubular grease removing film, the tip of the finger protrudes from the opening 12 at the end opposite to the mouth 11 of the grease removing film into which the finger has been inserted. It differs from the structure of the bag-shaped grease removal film that does not come out of the bag. In the case of a bag-shaped grease removing film, the shape is not limited to a rectangular shape as shown in FIG. 2 and may be a triangular shape as shown in FIG. 4 (A). As shown, the end 21 of the bag may be rounded. Further, the shape is not limited to these shapes, and the form is not limited as long as it has the structure and function of the grease removing film of the present invention.

The method of producing a film from a mixture of a biodegradable plastic, an inorganic filler, a water-absorbing polymer, and a pigment is not particularly limited.For example, a uniformly stirred raw material is put into a hopper of an extruder, Heating to a temperature range that does not exceed 200 ° C above the temperature at which the raw material melted,
An extrusion method of cooling and winding a tubular material extruded from the tip of a die by a screw is common. The extruded tube is cut as it is by a bag making machine, or is cut with a seal and finished into a bag or a tube.

[0019]

The degreasing film according to the present invention comprises one or more polyolefin resins selected from polyethylene, polypropylene and the like, or one crystalline resin 55 selected from polyester, polyethylene glycol, polyethylene terephthalate and the like. ~ 70wt%, vinyl acetate 5 ~ 15wt%, biodegradable plastic 20 ~ 30
wt%, 5-30 wt% of one inorganic filler selected from calcium carbonate, barium sulfate, silica, silicon, talc, kaolin, etc., 1-10 wt% of a water-absorbing polymer such as polyacrylic acid, and zirconium, cerium or zinc. Oxide, chromium oxide, black, yellow, red & brown iron oxide,
One kind of pigment selected from manganese violet, ultramarine blue, iron blue, chromium hydrate, metal oxide of silver powder or aluminum powder, carbon black, phthalocyanine blue, phthalocyanine green, azo pigment, cyan pigment, etc. And a mixture of titanium oxide with 0.1.
It is molded with a mixture containing 5 to 10% by weight. The grease removing film is different from the conventional grease removing film made of a porous film, and the surface of the film mainly composed of polyolefin resin or crystalline resin, vinyl acetate and biodegradable plastic is roughened by adding an inorganic filler. Thus, the effect of adsorbing sebum on the film was enhanced. In addition, by mixing the water-absorbing polymer, it has become possible to simultaneously absorb sweat that could not be removed by the conventional fat removing film.

It has also been found that the surface resistivity is reduced by mixing a biodegradable plastic with a polyolefin resin or a crystalline resin and vinyl acetate, as compared to a film containing only a polyolefin resin. As a result, it becomes difficult to remove fine dust in the air, and even if the grease removing film according to the present invention is slightly left on a desk or the like, it becomes possible to suppress dirt due to dust as compared with the conventional one. . Furthermore, since the biodegradable plastic is mixed, the biodegradable plastic is easily decomposed by microorganisms, so that it is easy to dispose.

Further, by making the grease removing film according to the present invention into a bag-like or tubular shape, the grease removing film fits on a finger, thereby making it easier to use than when using a sheet-like grease removing film. it can. And, in the case of a cylindrical grease removing film, since the grease removing film can be slid around the finger, the sheet portion without sebum dirt can be removed without performing the work of repeatedly holding the sheet. Just slide it to the center of your finger, making it very easy to use.
