Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a cosmetic sheet used for wiping off sweat and oil from the face, neck, etc.

[Conventional technology]

BACKGROUND ART Grease-blotting paper has traditionally been used to wipe away oil from makeup-applied faces.

Although some beaten paper is used as oil-absorbing paper, mainly flexible thin paper made by beating chemical pulp and bast fibers to a highly viscous state and then passing them through a supercalender is used.

In addition, paper white powder and paper blusher, which are tissue paper coated with white powder, are used to suppress the oil on the face that has been made up and at the same time leave a slight white powder on the face, making it easy to touch up makeup.

[Problem to be solved by the invention]

Conventional oil absorbing paper has low water absorption, so it can absorb sebum but has a problem in that it has a poor ability to absorb sweat.

In addition, conventional paper white powders are mainly used to touch up makeup by selecting a color that matches the skin color, and can only remove oil to the extent that it can be removed.

As described above, with the conventional technology, it is impossible to simultaneously wipe away sweat and oil, and if an attempt is made to increase the absorbency, the water absorbency decreases and the sweat absorbency is inevitably impaired.

[Purpose of the invention]

An object of the present invention is to solve the above-mentioned problems and provide a cosmetic sheet that can absorb sweat and oil at the same time.

In other words, it not only absorbs and wipes sebaceous lipids (triglycerides, wax esters, squalene, etc.) and epidermal lipids (cholesterol derivatives, phospholipids, triglycerides, etc.), but also improves sweat absorption by imparting water absorption. The purpose of the present invention is to provide a decorative sheet with a unique appearance.

Another object of the present invention is to provide a method for easily and inexpensively producing a decorative sheet having such water-absorbing properties and oil-absorbing properties.

[Means to solve the problem]

According to the present invention, the porous powder impregnated with or adsorbed with a water-absorbing agent and the porous powder impregnated with or adsorbed with a fat-absorbing agent adhere to the surface or inside of a flexible sheet-like object. The above object has been achieved by means of a decorative sheet characterized by:

Further, according to the present invention, the above-mentioned cosmetic sheet is provided, which is characterized in that porous powder impregnated with or adsorbed with a water-absorbing agent is attached to the surface or inside of an oil-absorbing paper having oil-absorbing properties. achieved its purpose.

In the present invention, porous powder impregnated with or adsorbed with a water-absorbing agent or a fat-absorbing agent is microencapsulated,
This micro-encapsulated porous powder may be used as the porous powder.

In addition, in the present invention, in addition to the porous powder impregnated or adsorbed with water absorbing agents and fat absorbing agents, ultraviolet absorbers, fragrances, antiperspirants, bactericidal agents, antifungal agents, and deodorants are also used. A decorative sheet can be obtained by attaching porous powder impregnated with or adsorbing at least one kind to a flexible sheet-like material.

According to the method of the present invention, a porous powder impregnated with or adsorbed with a water-absorbing agent and a fat-absorbing agent is first prepared;
Next, this porous powder is attached to a flexible cosmetic sheet.

To make a porous powder impregnated with or adsorbed with a water-absorbing agent and a fat-absorbing agent, the water-absorbing agent and the fat-absorbing agent are impregnated or adsorbed into separate porous powders, or the water-absorbing agent and the absorbent are mixed together. The porous powder is impregnated or adsorbed with this mixed liquid by mixing with a fat absorbing agent. Further, after the porous powder is impregnated with or adsorbed with a water absorbing agent and a fat absorbing agent in this manner, the porous powder may be microencapsulated.

In order to attach the porous powder impregnated or adsorbed with a water absorbing agent and a fat absorbing agent to a sheet-like object, the porous powder and granular material can be dipped onto the sheet-like object together with a binder, or one side or one side of the sheet-like object can be attached. It can be coated or sprayed on both sides.

When the sheet-like material is paper, porous powder impregnated with or adsorbed with the water-absorbing agent and fat-absorbing agent may be added at the time of paper making.

[Effect]

According to the present invention, porous powder impregnated with or adsorbed with a water-absorbing agent or oil-absorbing agent is attached to the surface or inside of a flexible cosmetic sheet, so that the water-absorbing agent or oil-absorbing agent acts This makes it possible to create a cosmetic sheet that can absorb sweat and oil at the same time.

Therefore, normally, as time passes after applying makeup to the face, sebum builds up on the face and the makeup comes off due to sweating, but if the cosmetic sheet of the present invention is pressed against the face, the makeup can be removed. It absorbs sebum that stands out on the face without breaking it, and it also has water absorbency to improve sweat absorption, so it can also absorb sweat.

Even if the sheet itself does not have any of the water absorbency or oil absorbency required for a cosmetic sheet, such as a fabric made of synthetic fibers, such as a nonwoven fabric,
By attaching porous powder impregnated with or adsorbed with a water-absorbing agent or oil-absorbing agent to a decorative sheet, water-absorbing properties and oil-absorbing properties can be imparted to the sheet.

Further, although conventional oil-absorbing paper has oil-absorbing properties, it has little water-absorbing property, so according to the present invention, a porous powder impregnated with or adsorbed with a water-absorbing agent is used as a fat-absorbing paper. By adhering to the paper, it is possible to create a cosmetic sheet that can absorb sweat and sebum at the same time.

Water-absorbing agents and fat-absorbing agents are usually commercially available in liquid form.
Microcapsulating liquid water-absorbing agents and oil-absorbing agents is time-consuming, has poor production efficiency, and increases manufacturing costs. Just by soaking the powder,
A water-absorbing agent or a fat-absorbing agent can be easily impregnated or adsorbed into the porous powder. Therefore, compared to making microcapsules from liquid water-absorbing agents and oil-absorbing agents, it is possible to produce porous powder impregnated with water-absorbing agents and oil-absorbing agents at a much lower cost. Can be manufactured cheaply.

In the present invention, in addition to imparting oil-absorbing properties and water-absorbing properties (sweat-absorbing properties), the porous powder is impregnated with an antiperspirant, a bactericidal agent, an ultraviolet absorber, a fragrance, an antifungal agent, a deodorizing agent, etc. Alternatively, the porous powder may be attached to a sheet-like material by adsorption. As a result, body odor can be prevented by suppressing the sweat that comes out one after another, and by killing bacteria on the skin surface that act on sweat and oil and generate unpleasant odors.

As deodorants, SF500M (product of Shiraimatsu Shinyaku Co., Ltd.), Sumeral (product of Environmental Science Development Co., Ltd.)
etc. are used.

The porous powder used in the present invention may have micropores throughout the powder or may be a hollow porous powder. As the porous powder, the following may be used.

As the inorganic fine porous powder, alkaline earth metal carbonates (e.g., calcium carbonate, barium carbonate, cobalt carbonate, basic copper carbonate, etc.), alkaline earth metal silicates (e.g., calcium silicate, magnesium silicate, silicic acid) aluminum, etc.), metal oxides (for example, silicic anhydride, iron oxide, alumina, cobalt oxide, copper oxide, etc.), diatomaceous earth, ceramics, etc.

There are powder and granular materials, porous powder and granular materials made of synthetic fibers (for example, void-filled fiber powder), and the like.

Fine porous powder particles having a size of about 0.5 μ to 100 μ can be used, but those having a size of about 1 μ to 50 μ are preferable.

The shape of the powder or granules is not particularly limited, and any shape such as spherical, flat, amorphous, etc. can be used as long as it is microporous.

As a microporous powder currently available on the market,
For example, there are the following products.

*Product name: Zeolum (Material: Aluminum silicate, Manufacturer: Toyo Soda Co., Ltd.), *Product name: Zeolite (Material: Aluminum silicate, Manufacturer: Nippon Builder Co., Ltd.), *Product name: Carplex (Material: Silicon oxide,
Manufacturer: Shionogi Pharmaceutical Co., Ltd.), *Product name: Silica #6-B (Material: Diatomaceous earth, Manufacturer: Chuo Silica Co., Ltd.), *Product name: Gottu Ball (Material: Silicic anhydride, Manufacturer: Suzuki Yushi Kogyo Co., Ltd.), *Product name: Chitosan ball (Material: Chitosan,
Manufacturer: Fujibo Co., Ltd.), *Product name: Polyethylene porous (Material: Polyethylene, Manufacturer: Spacey Chemical Co., Ltd.), *Product name: Fluorite (Material: Calcium silicate, Manufacturer: Tokuyama Soda Co., Ltd.), *Product Name: Avicel (Material: Cellulose-based porous powder, Manufacturer: Asahi Kasei Corporation).

The porous powder described above may be impregnated with or adsorbed with a water-absorbing agent, a fat-absorbing agent, or other functional treatment agent in the following manner.

Mix the porous powder and the water absorbing agent or fat absorbing agent or other functional processing agent in the desired ratio, stir thoroughly, and leave as it is for several hours to remove the water absorbing agent or fat absorbing agent or other functional processing agent. The treatment agent is uniformly permeated into the porous powder, and the water-absorbing agent, fat-absorbing agent, or other functional treatment agent is impregnated or adsorbed into the fine pores of the porous powder. If necessary, it may be heated to 70 to 80° C. to speed up the penetration of the water absorbing agent, fat absorbing agent, or other functional processing agent into the porous powder.

Alternatively, porous powder can be prepared by mixing porous powder, a water absorbing agent, a fat absorbing agent, optionally other functional treatment agents, and an appropriate liquid (e.g., water, solvent, etc.). Water-absorbing agents, fat-absorbing agents (and other functional treatment agents), and liquids are impregnated or adsorbed into the micropores of the body. In this case, excess liquid may then be removed by spray drying.

In addition, when impregnating or adsorbing a relatively viscous water-absorbing agent, oil-absorbing agent, or other functional treatment agent into porous powder, it is necessary to When mixed with powder or granules, or by adding an appropriate liquid to them, the mixture is placed in a container, the pressure is reduced, and the pressure is returned to atmospheric pressure. The processing agent penetrates well into the porous powder. That is, when the pressure is reduced, the air inside the fine pores of the porous granular material escapes due to the pressure difference between the inside and outside of the porous granular material. Thereafter, when the pressure is returned to atmospheric pressure, a water-absorbing agent, oil-absorbing agent, or other functional processing agent is forced into the air-free micropores by the atmospheric pressure.

In addition, in the present invention, a porous powder impregnated with or adsorbed with the above-mentioned water-absorbing agent, oil-absorbing agent, or other functional processing agent is used as a core material, and this core material is surrounded by microcapsules. You may also use this. Since the porous powder is a solid powder, it can be easily and efficiently microencapsulated by spray drying.

The materials for the microcapsules include gelatin, gum arabic, pectin, sodium alginate, CMC,
polystyrene, polyurethane, methylol urea,
Methylolmelamine, polyamide, calcium silicate, etc. can be used.

Comparing the case where a water-absorbing agent or oil-absorbing agent is impregnated or adsorbed into porous powder as in the present invention and the case where the water-absorbing agent or oil-absorbing agent itself is microencapsulated as a core material, the following results are obtained. There is a difference.

Water-absorbing agents and fat-absorbing agents are usually commercially available in liquid form, or can be easily made into liquid form by dissolving them in a solvent, so just by immersing the porous powder in the solution,
A water-absorbing agent or a fat-absorbing agent can be easily impregnated or adsorbed into the porous powder. On the other hand, in order to form microcapsules using a liquid as a core material, interfacial polymerization method, phase separation method (coacelvation method),
There are interfacial precipitation methods, but all of them are time-consuming, have poor production efficiency, and are expensive to manufacture.

In terms of morphology, the porous powder is an open capsule, and the microcapsule is a closed capsule. In other words, porous powder cannot seal the water-absorbing agent or fat-absorbing agent, but microcapsules can completely seal it.

Therefore, the bleeding effect of water absorbing agents, fat absorbing agents, etc. in both cases is greater in porous powder, and when microcapsules are broken, water absorbing agents, fat absorbing agents, etc. come out.

Since porous powder is an open capsule,
Impregnated or adsorbed water-absorbing agents, fat-absorbing agents, etc. can be released more easily than in microcapsules. Therefore, according to the present invention, the water-absorbing agent, fat-absorbing agent, or other functional treatment agent is a substance that is particularly easily volatilized or bleed,
If the water-absorbing agent, oil-absorbing agent, etc. easily volatilizes or bleeds simply by impregnating or adsorbing the porous powder or granular material as mentioned above, use the porous powder-granular material impregnated with or adsorbing the water-absorbing agent, oil-absorbing agent, etc. This may be microencapsulated using as a core material. In this way,
The water-absorbing agent, oil-absorbing agent, etc. inside the micropores are less likely to be released, and the performance life of the water-absorbing agent, oil-absorbing agent, etc. is extended.

According to the present invention, a porous powder impregnated with or adsorbed with a water absorbing agent, a fat absorbing agent, and other functional treatment agents as desired is prepared as described above, and the porous powder is mixed with a binder. and attach it to a sheet-like object.

Examples of the binder include synthetic resin emulsion, synthetic resin solution, etc., such as polyurethane aqueous dispersion, NBR latex, acrylic ester emulsion, polybutene emulsion,
CMC, gelatin, PVA, gum arabic, etc. may be used.

Porous powder is mixed into a binder, and the porous powder is attached to a flexible sheet-like material by an appropriate method such as dipping, coating, or spraying.

Alternatively, when the sheet-like material is paper, porous powder impregnated with or adsorbed with a water-absorbing agent, a fat-absorbing agent, etc. prepared as described above is added at the time of paper making. In this way, it is possible to produce a sheet (paper) in which the porous powder is contained inside. In this case, there is no need to use a binder.

In addition, in each of the above-mentioned methods, if the sheet-like foam is to have two or more functionalities (water absorbency and oil absorbency, and other functionality as necessary), for example, treatment agents with different functions may be used. (Water absorbing agents, fat absorbing agents, etc.) are impregnated or adsorbed into separate porous powders, and the porous powders impregnated with or adsorbed with these different water absorbing agents, fat absorbing agents, etc. are made into a single sheet. It may be attached to objects in a divided state.

For example, a water-absorbing agent and a fat-absorbing agent are impregnated or adsorbed into separate porous powders, and the porous powder impregnated with or adsorbing the water-absorbing agent is placed on one side of a sheet, and the fat-absorbing agent is placed on the opposite side. The impregnated porous powder may be coated to provide different functions to the front and back sides of the sheet-like material. Alternatively, porous powder impregnated with or adsorbed with each water-absorbing agent or fat-absorbing agent may be printed in the shape of a divided pattern on only one side of the sheet.

Alternatively, water absorbing agents, fat absorbing agents, etc. may be impregnated or adsorbed into separate porous powders, and the porous powders impregnated with or adsorbing these different water absorbing agents, fat absorbing agents, etc. may be mixed in advance. It may also be attached to a flexible sheet-like material.

Instead of impregnating treatment agents with different functions into separate porous powders as described above, treatment agents with different functions (water absorbing agent,
After mixing a fat absorbing agent, etc., it may be used by impregnating or adsorbing it into porous powder.

The cosmetic sheet of the present invention may be used as it is like conventional oil-absorbing paper, or it may be used like conventional paper white powder by applying white powder to the sheet-like product.

〔Effect of the invention〕

According to the present invention, porous powder impregnated with or adsorbed with a water-absorbing agent or oil-absorbing agent is attached to the surface or inside of a flexible cosmetic sheet, so that the water-absorbing agent or oil-absorbing agent functions effectively. This allows it to absorb sweat and oil at the same time. That is, normally, as time passes after applying makeup to the face, sebum builds up on the face or sweats, causing the makeup to come off, but if the cosmetic sheet of the present invention is pressed against the face, the makeup will come off. It absorbs the sebum that stands out on the face, and also has water absorbency to improve sweat absorption, so it can also absorb sweat.

In the cosmetic sheet of the present invention, even if the sheet-like material itself does not have any water absorption or oil absorption properties required for a cosmetic sheet, such as a fabric made of synthetic fibers, water absorbing agents or oil absorbing agents may be used. By attaching porous powder impregnated with or adsorbed to a decorative sheet, it is possible to impart water absorbency and oil absorbency to the sheet.

Further, although conventional oil-absorbing paper has oil-absorbing properties, it has little water-absorbing property, so according to the present invention, a porous powder impregnated with or adsorbed with a water-absorbing agent is used as a fat-absorbing paper. By adhering to the paper, it is possible to create a cosmetic sheet that can absorb sweat and sebum at the same time.

Water-absorbing agents and fat-absorbing agents are usually commercially available in liquid form.
Microcapsulating liquid water-absorbing agents and oil-absorbing agents is time-consuming, has poor production efficiency, and increases manufacturing costs. Just by soaking the powder,
A water-absorbing agent or a fat-absorbing agent can be easily impregnated or adsorbed into the porous powder. Therefore, compared to making microcapsules from liquid water-absorbing agents and oil-absorbing agents, it is possible to produce porous powder impregnated with water-absorbing agents and oil-absorbing agents at a much lower cost. Can be manufactured cheaply.

According to the present invention, the porous powder particles are made to have fat absorption properties, water absorption properties (sweat absorption properties), and also contain antiperspirants, disinfectants, ultraviolet absorbers, fragrances, antifungal agents, deodorants, etc. This porous powder material can be attached to a sheet-like material by impregnating or adsorbing it onto a body. As a result, it suppresses sweat that comes out one after another, sterilizes bacteria on the skin surface that acts on sweat and oil and produces unpleasant odors, prevents body odor, and achieves other desired effects. Functions can be imparted to decorative sheets.

Further, according to the present invention, when a fabric such as a nonwoven fabric or a woven fabric is used as the sheet-like material, it is economical because if the sheet-like material becomes dirty, it can be washed and used repeatedly. Furthermore, its functionality does not deteriorate even after repeated washing, and it can perform its functions for a long period of time. In other words, since water-absorbing agents, fat-absorbing agents, etc. are impregnated or adsorbed into the porous powder, even if the cosmetic sheet is repeatedly rubbed and washed, the fine particles of the porous powder adhering to the sheet will be removed. Water absorbing agents, fat absorbing agents, etc. that are impregnated or adsorbed inside the pores are not washed away.

The water-absorbing agent, fat-absorbing agent, etc. impregnated or adsorbed inside the micropores of the porous powder are gradually released (for example, similar to Oiles bearings, they gradually ooze out from the inside), prolonging their function. It can be performed over a period of time. Therefore, the water-absorbing agent and fat-absorbing agent of the decorative sheet of the present invention are durable.

According to the method of the present invention, a porous powder is impregnated with or adsorbed with a water absorbing agent, a fat absorbing agent, etc., and then attached to a sheet material, so that it is not affected by the properties of the water absorbing agent, fat absorbing agent, etc. , a decorative sheet can be easily produced.

Furthermore, according to the method of the present invention, porous powder impregnated with or adsorbed with a water-absorbing agent or a fat-absorbing agent can be directly added during paper making. That is, since the water-absorbing agent, oil-absorbing agent, etc. are impregnated or adsorbed in the porous powder, moisture and heat during paper making have little effect on the water-absorbing agent, oil-absorbing agent, etc. In this way, the decorative sheet of the present invention can be easily produced by directly adding powder to the paper production process.
