2. Description of the Related Art Conventionally, facial treatment methods include (a) applying a lotion, an emulsion, a serum or a nourishing cream containing a facial agent to the face, or (b) a pack containing a facial agent on the face. It has been proposed to apply agents.

[0003] However, in the method (a), the facial treatment agent can hardly be absorbed into the skin due to the barrier effect caused by the stratum corneum, and the desired facial effect cannot be obtained. Although the method of b) has the effect of adsorbing and removing dirt on the skin surface with a pack agent, the method of (a)
Similarly to the above, the skin care agent can hardly be absorbed into the skin due to the barrier effect caused by the stratum corneum, and the desired skin care effect cannot be obtained.

[0004] In addition, in the above-mentioned beautifying methods (a) and (b), when these methods are employed in winter, the lotion or the pack is cold, and when applied to the face, it becomes cold and uncomfortable. I often feel it. For this reason, the degree of freedom in use is often limited, for example, the use is limited after bathing.

Therefore, as another beauty treatment method, a steamed towel is applied to the face, and the moisture and heat from the steamed towel are supplied to the face.

However, in this beauty treatment method, it is difficult to control the temperature of the steamed towel, and the heat retention time is short, the stratum corneum cannot be sufficiently retained, and the heating time required for the beauty treatment cannot be secured. It is necessary to repeat the application and removal of the towel a plurality of times, which leaves annoyance.

Therefore, recently, a facial mask and a facial treatment method described below have been proposed. That is, as a facial mask, at least the side that is in close contact with the face is made of a flexible sheet material, and a fastening mask is integrally provided on both the left and right sides of a hollow mask body that can accommodate hot water. (JP-A-59-14804).

[0008] This facial mask may be used in contact with a face coated with a facial cream containing a placenta extract, collagen or the like as a main component, or may be used alone without applying a facial cream or the like. Pressing while warming the entire face with warm water in the hollow part, extending the wrinkles of the face, removing fat, exudates, etc.This facial mask turns the tightening band to the left and right of the head, The fastening device is used in a state where the ear is exposed from the ear canal and is strongly pulled.

[0009] As a heat treatment pack, a heat treatment agent containing paraffin as a main component in a water-tight bag has been proposed (Japanese Utility Model Application Laid-Open No. 61-96911).

In this case, a shape preserving agent mainly composed of clay fine powder such as kaolin or bentonite is added as an auxiliary agent to the thermotherapeutic agent.

[0011] In this thermotherapy pack, a thermotherapy agent containing paraffin as a main component is stored in a water-tight bag so that the bag can be heated, and the thermotherapy pack is directly placed in warm water and heated. By taking out when the temperature reaches about 55-60 ° C and hitting the affected area,
A hyperthermia treatment is performed.

At this time, it has been proposed to previously apply olive oil or cream, a fragrance, turpentine oil or menthol to the face, or to add a fine powder of radioactive ore.

[0013] As a facial warming pack, a face-shaped bag is formed of a flexible substance, and the bag is provided with a penetrating eye-corresponding hole, a mouth-corresponding hole, and a nose protruding hole, and is provided on one surface of the bag. Holes with crystal breaks are drilled, and the bag is filled with a solution that repeats supercooling and crystallization and generates heat at the time of the break, and sealed, and the label is releasably adhered to the hole with crystal breaks. There has been proposed a closed type (Japanese Utility Model Laid-Open No. 63-180023).

In this method, heat generated when a supercooled liquid crystallizes is used as a heat source.

A projecting portion is formed on the left and right sides of the facial warming pack, and a string insertion hole for attachment to the face is formed in the projecting portion, and a string is attached to the string insertion hole. Is wound around the head, and the facial warming pack is attached to the face.

As a facial mask, a planar heating element that generates heat when energized is buried in a mask body that is shaped according to the shape of a person's face, and an electrode is provided on a sheet-like substrate as the planar heating element. A device using a printed wire and a heating material has been proposed (Japanese Patent Laid-Open No. 9-12 / 1997).
2166).

In this case, it is also disclosed that a substance which emits far-infrared rays is mixed into the heating material of the sheet heating element.

In this facial mask, a planar heating element using a power supply is used as a heating source, and a commercial power supply or a battery is used as the power supply.

This facial mask is used by putting it on the face of a person. At this time, a band is put on the back of the head, the mask is held against the face, and the surface heating element is energized in this state. Then, the planar heating element generates heat and heats the face.

As a facial cosmetic method, it has been proposed to heat a face by using a heating device using a sheet-like chemical heating element mounted on the face (Japanese Patent Application Laid-Open No. 56-85336). Gazette).

The sheet-like chemical heating element is formed by an oxidation reaction,
Alternatively, a drug or a composition that generates heat due to a phase change such as dissolution or hydration is used.

A heating device using the sheet-like chemical heating element is formed into a mask having holes or cuts in human eyes, mouth and nose. It is disclosed that the face is directly heated as it is, a cosmetic pack is applied to the face, or a nutrient / bleaching cream is applied to promote the cosmetic effect.

By the way, the mounting of the heating device comprising the sheet-like chemical heating element on the face may be carried out simply by putting the heating device on the face. Alternatively, it is disclosed that a rubber cord, a rubber band, or the like is provided on the heating device, and the heating device is fixed so as to be pressed against the face by an ear or a head.

In the heat-generating sheet, a heat-generating agent that generates heat in the presence of air is arranged between the adhesive sheet having an adhesive layer on the inner surface and the porous packaging material. A pressure-sensitively sealed sheet using an adhesive of an adhesive sheet has been proposed (Japanese Patent Publication No. 7-49937).

In this case, in order to form a heat generating sheet for a beautiful face, the face, the eye, the cutout portion of the mouth, and the cutout of the nose are provided along the face to form the face.

By the way, when attaching the heat generating sheet for beauty treatment to the face, holes are provided at the left and right ends thereof, and the fixing sheet is fixed with a fixing tool such as a string or a rubber string attached to the hole. It is formed in a structure provided with a notch or the like.

In addition, by applying an adhesive layer or a far-infrared ray generating substance or the like to the outer surface of the base sheet in the heat generating sheet, it can be used on the curved surface of the body, or a compress is provided on the outer surface of the base sheet. It describes that an agent, a medicinal ingredient or the like is applied or adhered and integrated to form a hot compress.

[0028]

The above-mentioned facial mask is formed in a hollow shape and warms the face by putting warm water therein. However, this requires an apparatus for producing warm water and is troublesome. It cannot be used anytime, anywhere.

When hot water is used in this way, it is heavy,
In addition to feeling uncomfortable during use, it must be thick and strong enough to withstand the impact of falling or handling, but if the facial mask breaks, the warm water in the mask will cause the face and surrounding area to break. This can cause problems such as burns, stains on the face, clothing, and the surrounding area.

[0030] Furthermore, the present invention can be applied by applying a facial cream containing a placenta extract, collagen or the like as a main component to the face, and then applying a facial mask to the face. Poor adhesion between the face and the face, creating a gap between the mask and the face, barrier properties based on the stratum corneum, and further, the cream applied to the face is immediately dried by the heat of the facial mask, resulting in placental extract Are difficult to be absorbed percutaneously.

In particular, a tightening band is attached to this facial mask, and the band is tightened to fix the facial mask to the face. This causes inconvenience such as pain in the occiput.

The above-mentioned thermotherapy pack is designed so that the thermotherapy agent containing paraffin as a main component can be heated together with the bag.
It is stored in a water-tight bag, and this heat treatment pack is directly put in warm water and heated. When the temperature reaches an appropriate temperature of about 55 to 60 ° C., it is taken out and used by hitting the affected part. Now you need a device to make hot water,
It cannot be used anytime, anywhere.

When the thermal therapeutic agent containing paraffin as a main component is used as described above, if the bag is broken by dropping or the impact during handling, the thermal therapeutic agent in the thermal treatment pack scatters on the face and surroundings, In addition to burns, the face and clothes and the surrounding area are not only stained, but also because paraffin is used, the stains are persistent and post-treatment is extremely difficult.

[0034] Furthermore, after the face is coated with olive oil or cream, a fragrance, turpentine oil or menthol, etc., a heat treatment pack can be applied to the face. Poor adhesion to the face, a gap is formed between the pack and the face, a barrier property based on the stratum corneum, and further, menthol and the like applied to the face by the heat of the heat treatment pack immediately dry, resulting in menthol and the like. There are problems such as difficulty in transdermal absorption.

In particular, this device does not have a fixture for the heat treatment pack on the face and is unstable, and the pack is slipped or moved by slightly moving the face left or right or back and forth during use. Is required, which is extremely troublesome and lacks in convenience or the like. In addition, if a fine powder of radioactive ore is added, there is a risk of being exposed to radiation.

In the above-mentioned hot pack for facial beauty, the heat generated when the supercooled liquid is crystallized is used as a heat source, but this requires a long time for the temperature to rise and the temperature is not stable. However, there arises a problem that a required heating effect cannot be obtained.

In this case, the facial heat pack is used by applying it to the face. However, in this case, the adhesiveness between the facial heat pack and the face is poor, and the face can be sufficiently heated. Therefore, the required thermal effect cannot be obtained.

Furthermore, a string is attached to the facial warming pack, and the string is wrapped around the head and the facial warming pack is attached to the face. In addition, inconvenience such as pain in the temporal and occipital regions occurs.

In the above-mentioned facial mask, a planar heating element that generates heat when energized is embedded in a mask body that is shaped according to the shape of a person's face. And batteries are used, but this cannot be used unless there is a portable battery or a commercial power source, and the portability is extremely poor, it can not be used easily anytime, anywhere, and if it breaks down There are problems such as difficulty in treatment.

In this type of facial mask, such a problem becomes a very serious problem since the user is a woman.

Furthermore, this facial mask is used by putting it on a person's face. At this time, the band is hung on the back of the head, and the mask is held and fixed by putting the mask on the face. In addition to the poor properties, there are problems such as discomfort to the face and pain in the temporal and occipital regions when used.

In the above-described facial cosmetic method, a heating device using a sheet-like chemical heating element is attached to the face to heat the face. A hole is formed in the nose, or a mask is formed with a cut in it, and with this heating device, the face can be directly heated, or a makeup pack can be applied to the face,
Or apply nutrient and bleach cream.

However, in this case, the adhesion between the heating device and the face was poor, a gap was formed between the heating device and the face, the barrier property based on the stratum corneum, and the face was applied by the heating of the heating device. As a result of immediate drying of the cream or the like, there is a problem that the nutrient or the like is difficult to be percutaneously absorbed.

When the heating device is worn on the face, the heating device is put on the face and pressed with a mask that applies pressure, or an elastic cord, rubber band, or the like is provided on the heating device. Since the heating device is fixed to the face with your ear or head, it is difficult to handle.
During use, problems such as discomfort to the face, pain in the ears, the temporal region, and the back of the head occur, and the feeling of use is poor.

In the heat generating sheet described above, the heat generating sheet for a beautiful face is provided with eyes, a cutout in the mouth, and a cut in the nose along the face so that the face can be worn on the face. It is formed in.

When the heat generating sheet for beauty treatment is mounted on the face, holes are provided at the left and right ends thereof, and the heat generating sheet is fixed with a fixing tool such as a string or a rubber string attached to the holes. In addition, there are inconveniences such as discomfort to the face and pain in the ears, the temporal region, and the occipital region.

By the way, in the heat generation sheet for a beautiful face,
There has also been proposed a device in which a notch is simply provided at a position corresponding to the temple or the left and right of the chin, but this device has no means for fixing to the face, is unstable, and moves the face left or right or back and forth during use. However, the sheet is slipped or moved only by itself, so that the sheet needs to be reworked, which is extremely troublesome and lacks convenience and the like.

Further, in the heat generating sheet obtained by applying a poultice or a medicinal ingredient to the outer surface of the base sheet, the poultice applied to the face is immediately dried by the heat of the heat generating sheet. Are difficult to be absorbed percutaneously.

In addition, the above-mentioned items have poor adhesion to the face, and even when applied to the face, the effect of cleaning or beautifying the application site is extremely poor, and the desired facial effect cannot be obtained. is there.

The present invention has a moderate adhesiveness to the face,
By sticking on the face, it can be used easily anytime, anywhere, and it has a good feeling of use without tightening the head and ears, and it adheres to the face and has a sealing effect (so-called ODT effect) and a heating sheet The synergistic effect of the heat effect removes dirt and waste on the face easily and effectively, cleans the application site and effectively absorbs facial cosmetics, effectively activating the facial skin itself And enhances the attractiveness by beautifying the facial skin and keeping the skin healthy and beautiful.In addition, if the adhesive layer contains moisture, the moisture will be heated to increase the It is an object of the present invention to provide a pressure-sensitive adhesive heat generating sheet for facial beauty, which further enhances the effect.

[0051]

In order to achieve the above object, the present invention provides a pressure-sensitive adhesive heat generating sheet for a beauty treatment according to the present invention.
An adhesive heat generating sheet adhered to a specific portion or the entire surface of the face, the adhesive heat generating sheet has a heat generating sheet that generates heat by the presence of air, and an adhesive layer laminated on the entire surface or a part of one surface thereof. The heat generating sheet is composed of a flat wrapping material having air permeability and a paste-like heat generating composition enclosed in the wrapping material, and the adhesive layer cleans and beautifies a portion to be attached to the face. The present invention is characterized in that a cosmetic cosmetic material for enhancing attractiveness or keeping skin healthy is compounded.

This adhesive heat-generating sheet for facial use is used by being adhered to a specific portion or the entire surface of the face.
A shape that covers the entire face, or a specific part of the face, specifically, for example, the forehead, the periphery of the eyes, the outer or outer corner of the eye,
It is formed in a shape that covers the nose, the nose and its periphery, the chin, the periphery of the mouth or the cheek.

Further, in the present invention, there is provided a heat generating sheet which generates heat by the presence of air and an adhesive layer laminated on the whole surface or a part of one surface of the heat generating sheet. And a beautifying cosmetic material to enhance the attractiveness of the skin and keep the skin healthy.

The heating sheet used in the present invention includes:
Examples include a flat wrapping material having air permeability and a paste-like heat-generating composition sealed in the wrapping material.

[0055] The flat air-permeable packaging material refers to a case where at least one of the base material and the coating material constituting the packaging material has air permeability over the entire surface or a part thereof.

The flat wrapping material is composed of a base material and a coating material, and the base material and the coating material are formed of the same type of film or sheet, or the base material and the coating material are of different types. Or a sheet or a sheet or a sheet formed by folding a single film or sheet to form a base material and a covering material.

As the substrate and the coating material, at least one of them may be in the form of a film or a sheet having a water absorbing property.

The flat packaging material has air permeability. To control the air permeability with high accuracy, it is necessary to control the air permeability of the film or sheet (base material and / or coating material) with moisture permeability. It is preferable that the moisture permeability is determined by the Lissi method (L
50 to 10,000 using the yssy method (L80-4000H type)
The range of 0 g / m ² · 24 hr is generally used, but is not particularly limited because it differs depending on the use and purpose of the heat-generating adhesive heat-generating sheet.

When the substrate and / or the covering material are composed of a plurality of layers of a breathable film, the moisture permeability as a whole is determined to be 50 to 10,000 g / m ² by the Lissy method.
-It is preferable to set the range to 24 hours.

When the water vapor transmission rate is less than 50 g / m ² · 24 hr, the calorific value becomes small and a sufficient heating effect cannot be obtained, which is not preferable. On the other hand, 10,000 g / m ² · 2.
Exceeding 4 hours is not preferable because the heat generation temperature becomes high and a problem may occur in safety.

Incidentally, the Lissi method (Lyssy method) is a method based on industrial standards in various countries around the world.
In SZ0208, a temperature of 40 ° C. and a relative humidity difference of 90% R
H, it is set to 10
A measurement sample is inserted into the boundary between the lower chamber in a state of 0% relative humidity and the upper chamber in which a highly sensitive humidity sensor is installed, and the relative humidity of the upper chamber with the humidity sensor is adjusted to 10% RH (100% -90). %), And about ± 1% width (％ R
H), that is, the time required for the humidity to increase from about 9% to about 11% (several seconds) is measured and compared with the result of calibration performed under the same conditions using a standard sample whose transmittance is known in advance. This is a method of obtaining the transmittance.

By the way, in the conventional powdery heat-generating composition, each component such as metal powder and moisture is blended in an optimum state, and the heat-generating composition is a powdery and porous body, and therefore has a small surface area. Because of its large size and extremely good contact with air, an oxidation reaction, that is, an exothermic reaction occurs immediately upon contact with air.

For this reason, while the exothermic composition is compounded at an appropriate compounding ratio, and a powdery exothermic composition is produced, the exothermic composition is dropped on a substrate and coated with a coating material to produce a heating element. Until the exothermic reaction occurs, causing loss due to the exothermic reaction of the exothermic composition and deteriorating the quality of the exothermic composition,
The product generated by the exothermic reaction solidifies, causing various adverse effects. Specifically, as this evil, for example,
Variations in the amount of exothermic composition dropped, reduced yield due to removal of coagulated material, difficulty in handling, complicated maintenance of manufacturing equipment, restrictions on operating time of working equipment or working hours of workers, difficulty in coagulated material processing And the like.

In order to solve such problems, when the exothermic composition is formed into a paste, free water prevents contact between the exothermic substance such as metal powder and air, that is, free water acts as a barrier layer. Expressing the function, while producing the exothermic composition, and producing a paste-like exothermic composition,
After laminating and transferring this on the base material by printing or coating such as screen printing, the exothermic reaction hardly occurs until the heating element is manufactured by covering with the coating material, and the exothermic composition Loss due to the exothermic reaction and deterioration of the quality of the exothermic composition are prevented, and solidification of the exothermic composition is prevented.

For this reason, the present inventor has obtained the knowledge that the yield and handleability are improved, that the maintenance of the manufacturing apparatus is easy, and that there is no restriction on the operating time of the manufacturing apparatus or the working hours of the worker. Has proposed a heating element using a paste-like heating composition (Japanese Patent Application No. 8-17740).
No. 4).

In the present invention, the paste-like heat-generating composition comprises a heat-generating substance, a water-absorbing polymer and / or a thickener, a carbon component and a metal chloride and water as essential components, Are formed. In this case, if necessary, a pH adjuster, an inorganic water retention agent and the like may be further blended to form a paste as a whole.

The paste-like exothermic composition is not particularly limited as long as it is composed of a component which reacts with oxygen in the air to cause an exothermic reaction and has a property of flowing when an external force is applied. is not.

Specifically, for example, those formed as a paste as a whole, including a heating substance, a water-absorbing polymer and / or a thickener, a carbon component, a metal chloride and water as essential components, are mentioned. The mixing ratio of the water-absorbing polymer is 0.1 to 7.5 with respect to 100 parts by weight of the heating substance.
Parts by weight and / or 0.1 to 10 parts by weight of a thickener, 1.5 to 15 parts by weight of a carbon component and 1 to 10 parts by weight of a metal chloride as essential components, and water Examples thereof include those formed in a paste form. In this case, if necessary, furthermore, 0.01 to 10 parts by weight of a pH adjuster and 0.5 to 10 parts by weight of an inorganic water retention agent with respect to 100 parts by weight of the exothermic substance.
It is also possible to mix parts by weight and form a paste as a whole.

The exothermic composition is formed into a paste, as described above, and its viscosity (temperature: 20 ° C.)
In the following manner, generally, 50,000 to 9,500,0
If the viscosity of the heat-generating composition is too low, such as less than 50,000 cps, the transferability of the heat-generating composition by printing or coating becomes poor, or the water becomes extremely excessive, and the other heat-generating composition becomes extremely excessive. Insufficient amount of component transfer, short heating time, exothermic composition seeping out of predetermined area on substrate, need to absorb large amount of water after transfer to packaging material, special structure It is not preferable because it is necessary to use a wrapping material or to complicate the structure of the heating element. On the other hand, if it exceeds 9,500,000 cps, the transferability deteriorates, the amount of transfer varies, and a heat generation reaction occurs on the surface. This is not preferable because there is a possibility of occurrence.

The viscosity is defined as R1 manufactured by Toki Sangyo Co., Ltd.
10 type viscometer, RE110U system, detection head RE
100U, controller RC100A) and SP
Using a P rotor, the number of rotations was 0.2 rpm (D = 0.4
(1 / S)) and a value measured at a measurement temperature of 20 ° C. This viscosity is a value at the time of transfer and lamination.

As another example of the paste-like exothermic composition, there is a specification attached to the application filed on Jun. 17, 1996 by the present applicant (specification of Japanese Patent Application No. 8-177404).
(Ink-like or cream-like exothermic compositions).

When the exothermic composition is formed in the form of a paste, the above-mentioned advantages can be obtained, and the merit that the paste-like exothermic composition can be easily and reliably transferred and laminated on a substrate by printing or the like. It happens.

That is, since the exothermic composition is in the form of a paste, for example, thick coating printing, gravure printing, offset printing,
Printing using known printing techniques such as screen printing and spraying, and coating and coating with a head coater, roller, applicator, etc., are extremely easy to transfer and laminate, and produce ultra-thin heating elements at high speed. As compared with the powdered material, the measurement accuracy is remarkably improved because of not including a non-uniform air layer, and the exothermic composition can be evenly distributed in the packaging material.

As the exothermic substance, an organic substance can be used, but iron powder, zinc powder, aluminum powder, magnesium powder or an alloy of two or more of these metals, which does not generate an odor due to the reaction. Powders, and further, mixed metal powders in which two or more of these are mixed are used. In particular, among these metal powders, safety, handleability, cost, storage stability, stability and the like are considered. It is desirable to use the best iron powder overall.

The water-absorbing polymer is mainly
A polymer material that absorbs water and an aqueous solution of a metal chloride smoothly and in large amounts can be mentioned. Specifically, for example, a self-cross-linked polyacrylate disclosed in JP-B-54-30710, Reaction products of a polyvinyl alcohol-based polymer and a cyclic anhydride disclosed in Japanese Patent Application Laid-Open No. 54-20093 and a crosslinked polyacrylate disclosed in Japanese Patent Application Laid-Open No. 59-84305 are mentioned. is there. Among these water-absorbing polymers, there are those which absorb water or a metal chloride aqueous solution to increase viscosity, but mainly have a function of smoothly absorbing a large amount of water or a metal chloride aqueous solution. Things.

A good example of a commercially available product of this water-absorbing polymer is Sunfresh ST-30MP manufactured by Sanyo Chemical Industries.
S, ST-100MPS, ST-500MPS, etc.
It is particularly preferable because it rapidly absorbs water and an aqueous solution of a metal chloride and has a high absorption amount.

Examples of the thickener include substances which absorb water or an aqueous solution of a metal chloride to increase the consistency or impart thixotropic properties. Examples of the thickener include bentonite, polyacrylate, polyethylene oxide and the like. , Polyvinyl alcohol, polyvinylpyrrolidone, tragacanth gum, locust bean gum, guar gum,
Gum arabic, alginate, pectin, carboxyvinyl polymer, polysaccharide thickener, CMC, cellulose derivative thickener such as ethyl acetate, hydroxyethyl cellulose, methyl cellulose or hydroxypropyl cellulose, water-soluble cellulose ether, etc. Or a mixture of two or more.

The water-soluble cellulose ethers include
For example, water-soluble cellulose ethers such as methyl cellulose in which cellulose is etherified with a methoxyl group, hydroxypropylmethyl cellulose in which cellulose is etherified with a hydroxypropoxyl group, and hydroxyethyl methyl cellulose in which cellulose is etherified with a hydroxyethoxy group, manufactured by Daiichi Kogyo Seiyaku Water-soluble cellulose ethers such as cellogen EP, cellogen BSH-12, Cesca MC, Cesca MHEC, and Cesca MHPC.

In the above-mentioned water-absorbing polymer and thickener, if desired, these may be treated with a surfactant or a surfactant may be combined therewith to improve the hydrophilicity.

As the carbon component, carbon black,
Examples thereof include graphite and activated carbon.Examples of metal chlorides include alkali metal chlorides such as sodium chloride and potassium chloride, and alkaline earth metal chlorides such as calcium chloride and magnesium chloride. Can be mentioned.

As described above, if the exothermic substance, which is a component of the paste-like exothermic composition, is covered with free water and the contact with air is obstructed,
In other words, if free water expresses a function as a barrier layer, even if a sticky heat generating sheet is manufactured using this kind of heat generating composition, the free water prevents contact with air, and almost all exothermic reactions occur. Therefore, it cannot be used as an adhesive heat generating sheet.

However, in this case, when a part of the moisture in the paste-like heat-generating composition is absorbed by the packaging material, free water, that is, a barrier layer is lost, and the moisture is absorbed by the packaging material, thereby generating heat. As a result of the composition becoming porous,
The contact with air becomes good, and a sticky heat generating sheet having good heat generation characteristics can be obtained.

On the other hand, in such a paste-like heat-generating composition in which the rate of heat generation is suppressed by free water, if the free water becomes excessive, the base material or the coating material is removed in order to remove the barrier layer of the heat-generating composition. It is necessary that the water absorption of the base material or the coating material is excessively large, and in this case, care must be taken not to absorb the water required for the exothermic reaction of the exothermic composition. Is important.

From the above viewpoints, in particular, assuming that the transfer thickness of the paste-like heat-generating composition is 0.1 to 1 mm, the water-absorbing amount of the substrate or the coating material having the water-absorbing property is assumed to be 0.1 to 1 mm. The range of amounts is generally from 1.5 to 1000 g /
m ² , preferably 3 to 650 g / m ² , particularly preferably 5 to 550 g / m ² .

The amount of water absorption of the heat-generating composition was determined based on the condition of the optimum moisture content, based on the conventional powdery heat-generating composition. Is measured depending on whether a lot of
The excess water amount is converted into the water absorption amount (g / m ² ).

In other words, the basis of the measurement conditions is such that when moisture in the exothermic composition is absorbed, the component ratio is such that an optimum moisture content can be obtained when a conventional powdery exothermic composition is obtained. However, this optimum moisture content is measured based on the excess amount of water and the heat generation characteristics.

By adjusting the amount of water absorption of the base material and / or the coating material (flat packaging material) as described above, it is possible to absorb the excess water in the paste-like heat-generating composition, thereby making it suitable for the exothermic reaction. When the excess moisture is absorbed by the flat packaging material as described above, the exothermic composition becomes porous, so that the contact with the air becomes better and the exothermic characteristics become better. is there.

That is, when such a water-absorbing base material and / or coating material is used to absorb water in the paste-like heat-generating composition, the amount of water absorbed is 1% of the water amount in the heat-generating composition. 0.5-60% by weight, preferably 2-5%
It is desirably in the range of 0% by weight, particularly preferably in the range of 2.5 to 45% by weight.

A packaging material for a heating element of water in the heat-generating composition
The absorption rate (k weight%) into the (flat packaging material) was measured by the following method. Using a water-absorbing base material and a coating material used for this packaging material, punching this into a circle having a diameter of 65 mm, and drying at 55 ° C. under reduced pressure of 1 to 2 mmHg for 24 hours, the base material piece and the coating material piece And the weight of each of them is measured. In this case, the weight of the base material piece is A ₁ (g), and the weight of the coating material piece is B ₁
(g).

Next, a diameter of 60 was placed on the dried substrate piece.
The exothermic composition is laminated by screen printing so as to have a circular shape of mm and a thickness of about 850 μm, and the weight A ₁ (g) of the base piece is subtracted from the total weight C (g) after lamination to generate heat. The lamination amount D (g) of the composition is determined. Assuming that the moisture content of the heat generating composition is P% by weight, the total water content (g) in the laminated heat generating composition is D × P / 100.

Further, after a dried coating material piece was laminated on the exposed surface of the heat-generating composition on the base material piece, an acrylic plate having a thickness of about 1 mm was placed thereon, and 2.5 kg of an acrylic plate was further placed thereon.
And leave it for 5 hours.

Thereafter, the base material piece and the coating material piece are peeled off, and the exothermic composition adhering thereto is almost completely removed with tweezers. Then, the weight of each of the base material piece and the coating material piece is reduced. Is measured. In this case, the weight of the base material piece is A ₂ (g), and the weight of the coating material piece is B ₂ (g).

Next, the base material piece and the coating material piece that have absorbed water are dried at a temperature of 55 ° C. under a reduced pressure of 1 to 2 mmHg for 24 hours, and the weight of each is measured. The weight of this substrate piece is A
₃ (g), and the weight of the coating material piece is B ₃ (g). K = [(A ₂ + B ₂ ) − (A ₃ + B ₃ )] ÷ The value determined by D × 100 was defined as the water absorption.

The water-absorbing substrate or covering material may be any of non-breathable and breathable ones, regardless of whether the material itself has water absorbency or not. Is not particularly limited as long as it has water absorbency.

As the substrate or covering material having water absorption, one or both sides of a non-breathable or breathable film or sheet on the side capable of absorbing moisture in the heat generating composition may be used.
It is desirable to laminate a water-absorbing material having a water-absorbing property, thereby imparting the water-absorbing property and preventing the exudation of water.

Specific examples of the water-absorbing material include foamed films or sheets having water-absorbing properties (foams such as water-absorbing foamed polyurethane), papers, and nonwoven fabrics and woven fabrics formed of fibers having water-absorbing properties. Or, in addition to nonwoven fabrics and woven fabrics containing water-absorbing fibers, or water-absorbing porous films or sheets, with or without water absorption, foamed films or sheets, nonwoven fabrics, woven fabrics or porous films or sheets Into, containing, impregnating, kneading, transferring or carrying a water absorbing agent to impart or increase water absorption, or this kind, cut the water absorbing material into its planar shape on which the exothermic composition is laminated, The cut pieces of the water-absorbing material are laminated and fixed on one or both sides (the inner surface of the packaging material) of a non-breathable or breathable film or sheet, and thereby, on one or both sides of the exothermic composition. That water absorption is imparted wants Te and the like.

The water-absorbent nonwoven fabric is formed of lyon, pulp, cotton, or the like, from the viewpoints of exhibiting excellent flexibility, extremely excellent feeling, and good feeling on the face. Things.

In the above flat packaging material, the joining portion between the base material and the covering material constituting the packaging material is bonded or adhered by an adhesive such as a heat adhesive, a heat fusion adhesive or a hot melt adhesive. However, it is desirable because there is no peeling during use, the quality is stable, and the exudation of moisture and the exothermic composition is prevented.

In the flat wrapping material, the base material and the coating material constituting the wrapping material are not particularly limited as long as they have water absorption as described above. In general, the base material and the coating material having no heat-fusing property have no or almost no heat-fusing property.

Therefore, in such a case, a layer of a hot-melt adhesive or a layer of a pressure-sensitive adhesive such as a hot-melt pressure-sensitive adhesive, What is necessary is just to heat-bond or adhere the base material and the coating material with an adhesive layer interposed therebetween.

When the base material and the coating material are thermally bonded or adhered in this way, a highly heat-sensitive adhesive heat-generating sheet for a beautiful face, which is extremely flexible and has a remarkably excellent feeling and feeling of use, is desirable.

Further, the use of a heat-sealing base material and a coating material capable of heat-sealing or heat-bonding improves the productivity,
This is desirable because the production cost can be reduced.

More specifically, for example, the water-absorbing base material is a laminate comprising a heat-sealing nonwoven fabric, a water-absorbing nonwoven fabric, and a synthetic resin film or sheet (air-permeable or non-air-permeable film or sheet). Formed, when the heat generating composition is laminated on the heat sealable nonwoven fabric in the substrate, a part of the moisture in the heat generating composition permeates the heat sealable nonwoven fabric, migrates to the water absorbent nonwoven fabric, and is absorbed. As a result, the barrier layer caused by the free water disappears, so that the exothermic composition is always in a water state suitable for the exothermic reaction, and the exothermic reaction causes the water in the water-absorbent nonwoven fabric to be sequentially exothermic as the exothermic composition is consumed. , A stable exothermic reaction is obtained.

In the present invention, at least one of the base material and the coating material is provided with a non-woven fabric which comes into contact with the heat-generating composition. The non-woven fabric comprises a heat-sealing non-woven fabric and a water-absorbing non-woven fabric. It is desirable that the heat-sealing nonwoven fabric be hydrophobic and the water-absorbing nonwoven fabric be hydrophilic because it exhibits excellent heat-sealing properties and water absorption.

Examples of the heat-sealing nonwoven fabric include a composite nonwoven fabric of polyester and polyethylene. More specifically, for example, a laminated nonwoven fabric of polyester fiber and polyethylene fiber (“FULVALE” manufactured by Daiki Shoji Co., Ltd.) and a composite nonwoven fabric -Type spunbonded nonwoven fabric or other composite-type spunbonded nonwoven fabric [made by Asahi Kasei Kogyo Co., Ltd. (trade name: Full Veil), using heat-adhesive fibers].

Other heat-sealable nonwoven fabrics include
A fibrous core, and a nonwoven fabric formed of a double-structured fiber whose outer periphery is covered with a coating layer, wherein the core is formed of polyester fine fiber or polypropylene fine fiber; One in which the layer is formed of polyethylene is exemplified. An example of the nonwoven fabric formed of the fibers having the double structure is a spunbond nonwoven fabric (product name: ELEVES) manufactured by Unitika Ltd. Examples of the composite heat-bondable fiber having a double structure include UNK polypro fiber UC fiber manufactured by Ube Nitto Kasei Co., Ltd., and Chisso Polypro ES manufactured by Chisso Corporation.

Examples of the ultrafine fibers include Spunbond (trade name: Alcima) manufactured by Unitika Ltd.

As the flat packaging material, there is generally mentioned one in which the base material is composed of three layers of A layer / B layer / C layer, and the coating material is composed of two layers of D layer / E layer. In this case,
A layer is a reinforcing layer, B layer is a ventilation control layer and a seepage prevention layer,
Layer C is a water-absorbing layer, layer D is a water-absorbing layer, and layer E is a breathable or non-breathable film or sheet.

The layer A is a so-called reinforcing layer and includes various nonwoven fabrics. The layer B is a layer for controlling air permeability and preventing the exothermic composition from seeping out. And a breathable film or sheet formed of a synthetic resin such as

The layer C is a layer having water absorbency and air permeability, and examples thereof include nonwoven fabrics formed of a water-absorbent material such as paper, cotton, and rayon.

The layer D may be the same as the layer C, and the layer E may be a gas-permeable or air-impermeable film or sheet made of a synthetic resin such as polyolefin or polyester. No.

For forming the polyolefin resin film, a usual molding apparatus and molding method may be used.
An inflation molding machine, a T-die molding machine and the like are suitably applied. In order to impart air permeability to the polyolefin resin film thus obtained, the film is stretched uniaxially or biaxially to form a porous film. The stretching may be performed by a conventional method using an ordinary stretching apparatus, and examples include roll stretching, simultaneous biaxial stretching, and sequential biaxial stretching.

In this case, as the polyolefin-based porous film, in addition to a polyolefin-based resin film directly formed by uniaxial stretching or biaxial stretching, a polyolefin-based porous film is obtained by stretching. The filler may be formed by eluting the filler with alkali, water, or the like.

The barrier layer is lost, so that the exothermic composition 5 is made porous so as to make good contact with the air. In this case, the flat wrapping material 6 becomes non-breathable. And a coating material 8 having air permeability.

The base material 7 is made of a nonwoven fabric layer made of a hydrophobic and heat-sealable polyester fiber and polyethylene fiber (manufactured by Unitika Ltd., trade name: Alsima A0504WTO, basis weight 50 g / m 2) so as to obtain sufficient flexibility. ² )

After bonding and laminating the entire surface with a polymer hot-melt adhesive (trade name: Despomelt PT-3, manufactured by NSC Japan Ltd.), the same bonding method is used (however, the bonding pattern intersects at a right angle with the previous angle). as), basis weight 50 g / m ^2, and a hydrophilic-absorbent cotton nonwoven, basis weight 50 g / m ^2, hydrophobicity and heat-sealable polyester fibers and polyethylene fibers composite spun bonded nonwoven fabric (manufactured by Unitika Ltd., Alcima cotton entangled product (trade name: Alcima A0504WTO) (trade name: Alcima cotton entangled product AC5050, manufactured by Unitika) Were sequentially bonded. The moisture permeability of the coating material 8 was 400 g / m ² · 24 hr by the Lissi method.

In the present invention, a paste-like heat-generating composition 5 to be described later is laminated in an elliptical shape by screen printing at a predetermined position on the heat-sealable composite nonwoven fabric in the base material 7, and the coating is performed from above. The covering material 8 is covered so that the heat-sealable composite nonwoven fabric of the material 8 comes into contact with the heat-generating composition 5, and the sealing portion between the base material 7 and the coating material 8 is heat-sealed around the heat-generating composition 5. In addition, a part of the moisture in the paste-like heat-generating composition 5 is absorbed by the cotton nonwoven fabric of the base material 7 and the cotton nonwoven fabric of the coating material 8 to lose the barrier layer,
Thereby, the exothermic composition 5 is configured to be porous so that contact with air is improved.

The paste-like exothermic composition 5 was produced by the following method. That is, iron powder which is a heating substance
(DKP manufactured by Dowa Tekko Co., Ltd.) 100 parts by weight of CMC (Cerogen EP, manufactured by Daiichi Kogyo Co., Ltd.) as a thickener
1.2 parts by weight, 0.3 parts by weight as a water-absorbing polymer (manufactured by Sanyo Chemicals Co., Ltd., Sun Fresh ST-500MPS), and 3.0 parts by weight of bentonite (manufactured by Hoyo Bentonite Co., Ltd., Yutaka 300) as an inorganic thickener Parts, activated carbon (SA-Super manufactured by Norit) 8.0 parts by weight, 4.0 parts by weight of sodium chloride as a metal chloride, 0.15 parts by weight of calcium hydroxide as a pH adjuster, and 34 parts by weight of water. It is kneaded and adjusted.

That is, the mixing ratio was determined by using activated carbon, a thickener,
Water absorbent polymer, bentonite, sodium chloride, PH
In the order of the adjusting agent, a mixing machine (T.K.
K. (Hivis Mix 2P-100 type, capacity 100 liters), stir for 5 minutes, add water while stirring, knead for 10 minutes, add iron powder and knead for 5 minutes, then clean off deposits in container And kneading again for 15 minutes, followed by discharging.

The exothermic composition 5 is in the form of a paste, has a small surface area, and has a limited contact area with air. In addition, the free water functions as a barrier layer for suppressing the contact between iron powder and air, so that the composition per unit time can be improved. As a result, the amount of oxidation per unit is remarkably limited. As a result, the oxidation reaction until the film-like or sheet-like coating material is laminated thereon to obtain a sticky heat-generating sheet for facial care is almost prevented.

00 (5.0% by weight), L-ascorbic acid 1.0% by weight, jojoba oil 2.0% by weight, squalane 2.0% by weight,
5.0% by weight of titanium oxide, 5.0% by weight of talc, 8.0% by weight of ethanol, 1.0% by weight of POE sorbitan monostearate and 37.0% by weight of ion-exchanged water
It consists of

Titanium oxide and talc were added to ion-exchanged water and sufficiently dispersed, and then sorbitol and PEG 400 were added.
Is added to make a uniform mixture, which is heated to 70 to 80 ° C., and then a polyvinyl acetate emulsion and polyvinyl alcohol are added and dissolved. Hereinafter, this is referred to as an aqueous phase mixture.

On the other hand, L-ascorbic acid, jojoba oil, squalane and POE sorbitan monostearate are added to ethanol and mixed until uniform. Hereinafter, this is referred to as an oil phase mixture.

This oil phase mixture is added to the above aqueous phase mixture, mixed until uniform, and then cooled to room temperature. The mixing was all performed by a homomixer.

[0169] Each of the cut adhesive heat-generating sheets for facial beauty is subsequently sent to a packaging step and enclosed in an airtight outer bag (not shown).

By the way, the paste-like exothermic composition 5 comprises:
After screen printing on the upper surface of the base material 7, a part of the water is gradually absorbed by the base material 7, and the coating material 8 is coated thereon. However, the time from when the paste-like exothermic composition 5 is screen-printed on the base material 7 to when it is sealed in the outer bag is extremely short, and during this time, the paste-like exothermic composition is sufficiently large to allow an exothermic reaction. The moisture of the object 5 is hardly absorbed by the substrate 7.

Therefore, there is no possibility that heat generation of the paste-like exothermic composition 5 occurs in the manufacturing process, and there is no risk of loss due to an exothermic reaction in the manufacturing process or deterioration of the quality of the exothermic composition 5. Further, in the process from the mixing of the paste-like heat-generating composition 5 to the screen printing on the base material 7, there is almost no possibility that the paste-like heat-generating composition 5 solidifies due to an exothermic reaction, the yield decreases due to solidification, the operation is interrupted, It is possible to prevent various adverse effects such as restrictions on operation time, difficulty and danger of cleaning the manufacturing apparatus, frequent cleaning of the manufacturing apparatus, and difficulty in coagulation treatment.

By the way, the free water in the paste-like heat-generating composition 5 is covered with the base material 7 by the time the cosmetic adhesive heat-generating sheet is sealed in a non-breathable bag and reaches the user through distribution. Since the moisture content is absorbed by the material 8 and the moisture content ratio is suitable for obtaining a predetermined heat generation temperature, the quality of the heat generation composition 5 does not deteriorate before the air-impermeable bag is broken and comes into contact with air. In addition, the quality of the exothermic composition 5 can be maintained at a high level, and the exothermic reaction is started immediately after the non-breathable bag is broken and the adhesive heat generating sheet for facial treatment is taken out, and the temperature is quickly raised to a predetermined exothermic temperature.

By the way, this paste-like exothermic composition 5
Was measured by the above-mentioned method, and found to be 3.0% by weight.

Example 2 In Example 1, instead of the whitening adhesive used in Example 1, a layer (thickness: 5) formed of the following whitening adhesive was used.
Except that 50 μm) was used, the same procedure as in Example 1 was carried out to obtain an adhesive heat-generating sheet 1 for a beautiful face to be used by sticking to a forehead.

That is, as a whitening adhesive, 17.5% by weight of polyvinyl alcohol, 7.5% by weight of carboxymethyl cellulose, 7.5% by weight of 1,3-butylene glycol, 1.0% by weight of L-ascorbic acid, 12% by weight of ethanol
Wt%, sodium lactate 0.3 wt%, POE oleyl alcohol ether 0.7 wt% and ion exchange water 5
It consists of 3.5% by weight.

Sodium lactate and 1,3-butylene glycol are added to ion-exchanged water to form a uniform mixture. After the mixture is heated to 70 to 80 ° C., polyvinyl alcohol and carboxymethyl cellulose are added, and the mixture is stirred and dissolved. Hereinafter, this is referred to as an aqueous phase mixture.

On the other hand, L-ascorbic acid and POE sorbitan monostearate are added to ethanol and mixed until uniform. Hereinafter, this is referred to as an oil phase mixture.

This oil phase mixture is added to the above aqueous phase mixture, mixed until uniform, and then cooled to room temperature. The mixing was all performed by a homomixer.

Example 3 As shown in FIG. 3, in Example 1, a substrate 7 similar to that used in Example 1 was used, and on this substrate 7, a material similar to that used in Example 1 was used. When screen-printing the paste-like heat-generating composition 5, a screen plate having a thickness of 850 μm is used, and the paste-like heat-generating composition 5 is screen-printed in a shape that covers the periphery of the eyes except for the eyes. The heat-generating composition 5 is heat-sealed with the base material 7 and the coating material 8 on the outer periphery of the heat-generating composition 5. , A substantially heat-sensitive adhesive heat-generating sheet 11 for a face was manufactured.

In this case, the same whitening pressure-sensitive adhesive layer (thickness: 550 μm) as that used in Example 1 was formed on the entire exposed surface of the base material 7 in the flat packaging material 6. The exothermic composition 5 was punched and cut by die cutting so that the seal width at the outer peripheral portion was 5 mm.

The adhesive heat-generating sheet 11 for beauty treatment is formed in a substantially eye mask shape covering the periphery of the eyes.
As in the case of Example 1, a part of the moisture in the paste-like exothermic composition 5 is absorbed by the flat wrapping material 6, and the barrier layer is lost, whereby the exothermic composition 5 becomes porous. It becomes good contact with air.

Examples 4 to 10 In the adhesive heat-generating sheet for facial beauty according to the present invention, the adhesive heat-generating sheet for facial beauty 12 in the form of an eye mask as shown in FIGS. 5 and 11 (Example 5), and a pair of left and right facial heat-generating adhesive heating sheets 13 for covering the outer and outer corners of the eye as shown in FIGS. 5 and 11. 12 to manufacture a heat-generating adhesive heat-generating sheet 14 for covering the chin (Example 6), or a nose and a nose as shown in FIGS. Adhesive heat generating sheet 15,
16 (Examples 7 and 8), and a facial heat-generating adhesive sheet 17 covering the cheek as shown in FIGS. 9, 11 and 13.
(Example 9), or the facial heat-generating adhesive sheet 18 covering the mouth and nose as shown in FIGS. 10 and 13 (Example 10). It is formed into a shape. These adhesive heat generating sheets for facial beauty can be manufactured by the same procedure and method as in the first embodiment.

By making it possible to use it by adhering it to a specific part of the face as described above, the adhesiveness with a predetermined part is extremely improved as compared with the adhesive heat-generating sheet for facial use used for the whole face. It is desirable because it can be applied to places of concern on the face, as well as being able to obtain a beautiful face effect, so that there is no waste in terms of economy.

In each of the above embodiments, since the paste-like exothermic composition 5 is used, the composition is stable even in the air, and the paste-like heat-generating composition 5 is printed on the base material 7 in any shape by printing such as screen printing. As a result, the heat-generating composition 5 of the present invention can be laminated, so that an adhesive heat-generating sheet for facial beauty of any shape can be easily obtained, and a part of the moisture in the paste-like heat-generating composition 5 is absorbed by the flat packaging material 6. As a result, the barrier layer is lost, whereby the exothermic composition 5 becomes porous and has good contact with air.

Next, a face-appearing adhesive heat-generating sheet 1 shown in Example 1 and a pair of left and right face-appearing adhesive heat-generating sheets 13 covering the outer and outer corners of the eye shown in Example 5 were prepared. The beauty test was conducted by the following method using the adhesive heat generation sheet for beauty 17 covering the cheek shown in FIG.

[0186] That is, the facial effect is a group of 25 panelists (40-53 years old women) suffering from wrinkles, spots, freckles, etc.
The names were divided into three groups.

For the group of 25 persons, the adhesive heat generation sheet 1 for the forehead shown in Example 1 and a pair of left and right facial adhesives for covering the outer and outer corners of the eye shown in Example 5 were used. The heat-generating sheet 13 and the heat-generating adhesive heat-generating sheet 17 for covering the cheeks shown in Example 9 were manufactured and sealed in a non-breathable outer bag. And forehead on the face as shown in FIG.
It was stuck and used on the outer and outer corners of the eyes and cheeks.

In this case, every day, in the morning, and 30 to 60 after bathing.
During a minute, as shown in FIG. 11, forehead on the face, the outer corner of the eye and the periphery of the outer corner of the eye and the cheek were repeatedly adhered and used for 35 days, and wrinkles, stains,
Facial effects such as freckles were determined.

The adhesive heat-generating sheets for facial beauty of Examples 1, 5 and 9 were manufactured and sealed in a non-breathable outer bag. After 24 hours had elapsed, each outer bag was broken. Then, as shown in FIG. 11, when applied to the forehead on the face, the outer corner of the eye and the periphery of the outer corner of the eye and the cheek and used, the exothermic temperature rises to about 38 ° C. in about 1 minute, and thereafter becomes 38 to 41 ° C. Exothermed for about 25 minutes.

The beauty effects obtained by repeatedly using the heat-generating adhesive heat-generating sheet according to each of the examples are as follows. In the forehead on the face, the outer corner of the eyes, the periphery of the outer corners of the eyes, and the cheeks, wrinkles, spots, and freckles on the face were inconspicuous, whitened and moist, the skin became younger, and it was recognized that the facial effect was remarkable 15 There is a name, wrinkles, spots, freckles on the face are thin and almost inconspicuous, white and moist, the skin becomes young, there are 7 people who have recognized that it has the facial effect, the remaining 3 people It also claimed that wrinkles, spots, and freckles were somewhat lighter, with some whitening effect.

In addition, during use, each of the heat-generating adhesive heat-generating sheets adhered to the face, did not cause skin irritation, and heat generation averaged over the entire surface was observed. Also, no skin irritation was observed at the time of peeling.

On the other hand, as a comparative example, in Examples 1, 5 and 9, except that the exothermic composition was omitted.
A facial adhesive sheet used for the forehead on the face, the corners of the eyes, the periphery of the corners of the eyes, and the cheeks manufactured in the same manner as in Examples 1, 5 and 9 was used.

Using the facial adhesive sheet according to this comparative example, the forehead, the outer corner of the eye, the outer corner of the outer corner of the eye, and the cheek were applied to the other group of 25 persons under the same conditions as in the examples. Was repeatedly applied and used for 35 days, and on the 35th day, the facial beauty effects such as wrinkles, spots, and freckles on the face were determined.

The beauty effects obtained by repeatedly using the cosmetic pressure-sensitive adhesive sheet according to each of the comparative examples are as follows. On the forehead on the face, the outer corner of the eyes, the periphery of the outer corners of the eyes and the cheeks, there was no one that was recognized as having a remarkable facial effect, but wrinkles, spots, and freckles on the face became thin and almost inconspicuous. Eight people admit that the skin becomes moist and younger and has a facial effect, and 11 people claim that wrinkles, spots, and freckles are somewhat thinner and some whitening effect is recognized. In addition, the remaining six argued that there was no change and no facial effect was observed.

During use of the pressure-sensitive adhesive sheet according to each of the comparative examples, each pressure-sensitive adhesive sheet for beauty treatment adhered to the face, there was no skin irritation, and no skin irritation was observed at the time of peeling. .

Further, as another comparative example, in Example 1, Example 5 and Example 9, the adhesive layer formed of an acrylic adhesive was used instead of the adhesive layer 3 formed of the whitening adhesive.
(Thickness 25 μm), except that an adhesive heat-generating sheet used for the forehead on the face, the outer corner of the eye and the outer corner of the eye and the cheek, which was produced in the same manner as in Example 1, Example 5 and Example 9 was used. .

Using this adhesive heat-generating sheet, the remaining 25 patients in one group were repeatedly adhered to the forehead on the face, the outer corner of the eye, the periphery of the outer corner of the eye, and the cheek for 35 days. A commercially available whitening cream containing L-ascorbic acid is applied to each part, and the adhesive heat-generating sheet is stuck thereon and used.
On the day, facial effects such as wrinkles, spots, and freckles on the face were determined.

The beauty effect by repeated use of the adhesive heat-generating sheet according to each comparative example is as follows. On the forehead on the face, the outer corner of the eyes, the periphery of the outer corners of the eyes and the cheeks, there was no one that was recognized as having a remarkable facial effect, but wrinkles, spots, and freckles on the face became thin and almost inconspicuous. There are 5 people who have moist and young skin and recognize that it has a facial effect, and 12 people claim that wrinkles, spots and freckles are somewhat thinner and some whitening effect is recognized. In addition, the remaining eight claimed that there was no change and no facial effect was observed.

In this case, during use of the adhesive heat generating sheet, the adhesiveness to the application site on the face is poor, that is, the adhesive heat generating sheet is hardly adhered to the face by the whitening cream. The whitening cream dries in about 1 to 2 minutes due to the heat of the heat generating sheet, and the percutaneous absorption of the whitening agent is poor due to the barrier function of the stratum corneum, and even when applied to the face, the application site is cleaned or beautified. It is recognized that the effect was extremely poor and the desired facial effect was not obtained.

[0200] From the above results, in each of the examples, compared with those in the comparative examples, the warming effect and the synergistic action of the cosmetic material for facial treatment were used to extend the wrinkles on the face and to conspicuous spots and freckles. It is possible to obtain an extremely excellent facial effect, for example, by eliminating whitening and making the skin white and moist.
