Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat insulating material for use in beauty or medical treatment (including massage). More specifically, it is heated on a microwave oven or the like to be directly applied to the face, neck, arms, legs or the like. The present invention relates to a heat insulating material for skin application and a heat insulating material for skin application.

[0002]

2. Description of the Related Art By warming the skin of the face, neck, arms, legs and the like, various cosmetic and medical effects can be obtained. For example, by warming the skin to improve blood circulation, not only a mental and physical relaxing effect can be obtained, but also nutritional supplementation to the skin can be promoted to restore freshness and transparency of the skin. You can also open pores and soften the dead skin.For example, you can easily remove dirt such as sebum and dust from the deep pores and remove old dead skin. You can also soften it and drop it. Furthermore, it is possible to expect a slimming / small face effect due to the sweating action.
Since various cosmetic effects can be expected in this way, heat retention and moisturization of the skin are essential steps in the field of beauty, especially in the field of beauty.

On the other hand, in a home that is not equipped,
It is not easy to effectively keep the skin warm, and there has been no disclosure of a facial pack material or the like that can obtain both the effects of keeping warm and moisturizing. Therefore, the present inventors intend to provide a heat-retaining material for skin coating and a heat-retaining material for skin sticking, which can be easily heated in a household microwave oven to obtain health effects and beauty effects.

As a heat insulation material for skin coating and a heat insulation material for skin attachment of this kind, as described in JP-A-8-501966, oats are contained in a package made of a porous sheet material having heat conductivity. There is disclosed a heat treatment pad which stores grains such as and is heated in a microwave oven for use. Also,
JP-A-9-225005 and JP-A-11-9652 disclose a "warm moxibustion pack" in which ceramic particles are contained in a container made of aramid fiber having excellent heat resistance. Wrap rock pieces of flame-retardant fiber cloth such as rayon and heat it in a microwave oven at about 70 to 100 ° C to use it as a heat pack, or heat it in a microwave in the form of a rubber water pillow. Is disclosed as prior art.

[0005]

However, the previously disclosed heat insulating material for skin heating for microwave oven described above is
Since it was not developed for beauty, it is difficult to make it thin, flexible, and easy to adapt to the skin.
In particular, there has been a problem as a heat insulating material for skin coating and a heat insulating material for skin application used for facial beauty.

[0006]

Therefore, the present invention focuses on an organic conductor gel that can be heated in a microwave oven or the like, and a gel-like heat insulating material for skin coating mainly composed of this organic conductor gel, and
A heat-insulating material for skin application is proposed, which has a structure in which a flexible sheet such as a non-woven fabric, a woven fabric or a sponge is coated with or impregnated with this organic conductor gel.

The organic conductor gel, that is, a gel-like substance composed of organic molecules having electrical conductivity, can be heated by microwave irradiation, and since it is gel-like, it is extremely easy to handle as compared with other conductors, and It is also suitable for forming into a form that is thin, flexible and easy to fit on the skin. Organic conductor gels are classified into charge transfer complexes and conductive polymers,
Furthermore, conductive polymers are classified into ionic conductivity, electronic conductivity, and mixed conductivity. In the present invention, any type of organic conductor gel can be used, but preferably, the solvent is allowed to enter the ion-conductive conductive polymer, especially the three-dimensional polymer network made of an acrylic acid derivative, from the viewpoint of easy availability. The hydrogel body obtained by this is preferable. Such an acrylic acid derivative crosslinked polymer has an electric conductivity of 10 or less.
It is particularly excellent in that it can be adjusted within the range of ^-5 to 10 ^-3 S / cm, the adhesive force to the skin can be freely adjusted, and it is extremely hypoallergenic to the skin. Conversely, in addition to electrical conductivity, adhesiveness to the skin, irritation to the skin, and the like are indicators for selecting the organic conductor gel in the present invention.

The heat insulating material for skin coating and the heat insulating material for skin sticking of the present invention can be easily used by using an electromagnetic wave heating device, especially a microwave oven for household use (radiation of electromagnetic waves near a frequency of 2,450 MHz). It can be heated. Heated heat-insulating material is applied to the skin of the face, neck, arms, legs, etc., and left on for a suitable period of time to remove swelling, improve blood circulation, massage, and other medical treatments. It has various effects such as softening the stratum corneum, opening pores, slimming effect, and promoting blood circulation to improve metabolism, thereby obtaining various health and beauty effects such as dullness, dark circles and swelling. It should be noted that the microwave oven is the easiest to use in view of the penetration rate into the home, but in the case of the present invention, it is also possible to heat using another electromagnetic wave heating device, for example, a high frequency induction heating device. is there.

Since polyolefin has a low dielectric constant and a small dielectric loss, electromagnetic wave energy can be effectively transmitted to the inside and can be efficiently heated. Incidentally, when heated in a microwave oven, since the internal pressure of the bag-shaped package may explode due to expansion of air and generation of water vapor, a conventionally known method, for example, providing a vent,

A PE film 5A having a thickness of 15 μm is laminated on the back surface side of A) to form a sheet body 4A.
As shown in (B), a mask is obtained by cutting into a full face shape. Next, as shown in FIG. 3C, a hydrogel body 2A (trade name "Technogel (Sekisui Chemical Co., Ltd.)" is obtained by allowing a solvent to enter the three-dimensional polymer network made of an acrylic acid derivative on the entire surface of this mask. Is evenly applied, the mask is folded with the gel-coated side inside, and as shown in FIG. 3D, the mask is enclosed in a plastic film bag 7A (a bag made of silica-deposited polyester film). .

The heat insulating material 1A for skin application of this example is preliminarily cut into the plastic film bag 7A so as not to explode due to internal pressure, and then heated to an appropriate temperature in a microwave oven, and then adhered to the entire surface of the face as needed. If it is left as it is for a while, the health effect, esthetic effect and relaxing effect can be obtained by the heating effect. At the same time, the action of ceramide derived from natural yeast can supply water to the stratum corneum to give the skin firmness and moisture.
