Abstract

PURPOSE:To provide a packing agent containing an aluminosilicate adsorbed with CO2, effective to promote the blood flow at the surface of skin and accelerate the absorption of nutrient and discharge of waste product and removable from the skin surface smoothly by the foaming action of CO2. CONSTITUTION:The objective packing agent contains an aluminosilicate containing adsorbed CO2. The aluminosilicate is preferably a synthetic zeolite of formula (M is metallic atom having an atomic valence n and is preferably Ca; x is 0.7-1.5; y is 0.8-10), and the absorption of CO2 is carried out by contacting the zeolite with CO2 under CO2-pressure of 1-10kg/cm<2> at <=20 deg.C. To release CO2 in the use of the packing agent, it is preferable to mix the first agent containing the aluminosilicate adsorbed with CO2 with the second agent containing an aqueous solution of a water-soluble polymer at a ratio of 2:98-70:30 unformly before use and applying the mixture to the diseased part to be packed. The second agent may further contain a humectant, flavor, nutrient, etc.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a pack agent, and more particularly to a pack agent having a blood circulation promoting effect.

[Conventional technology]

Pack beauty methods cover the skin with a film for a certain period of time, during which time it replenishes nutrients and moisture to the skin, while also regulating the functions of the sebaceous glands and sweat glands, which promotes blood circulation in the skin and increases the absorption of certain nutrients. It has an anti-aging effect that provides smoothness and moisture, and simultaneously removes dust that adheres to the skin surface and waste products secreted on the skin surface when the pack is removed, and also removes the primary keratin of the aged epidermis and creates a new epidermis. It is an effective beauty method that can also be expected to have a metabolism-promoting effect that promotes cell formation.

Many packs that have been commercially available for this purpose are made by adding humectants, thickeners, alcohol, astringents, fragrances, nutrients, etc. to an aqueous solution of water-soluble polymer substances such as polyvinyl alcohol. In use, the pack agent is applied, left to dry for about 20 minutes, and then the film-like membrane is peeled off.

[Problem that the invention seeks to solve]

However, since these conventional methods aim to promote blood circulation by simply covering the skin surface with a film of the pack, the absorption of nutrients, etc. contained in the pack into the skin is weak, and most of them are difficult to absorb into the skin. In reality, they were thrown away as soon as the film peeled off. Therefore, the effects of the drugs contained in the pack can hardly be expected, and there is a drawback that it is necessary to prepare the skin with lotion or the like and apply a nutritional cream after the pack.

In addition, when the pack agent coating is removed, since the skin and the pack agent coating are strongly adhered to each other, a portion of the deep stratum corneum of the epidermis is also forcibly removed, which may cause damage to the skin if the skin is weak. There is a risk of getting a rash.
The drawback is that it can normally only be used once a week.

Furthermore, there is also a method of applying a powdered substance in the form of slurry or cream with water, etc., and wiping it off after the bag, but this method is difficult to apply and requires wiping off and cleaning after the pack. The disadvantage is that it is troublesome,
None of the conventional methods were satisfactory.

[Means for solving problems]

In order to solve the various problems of such conventional pack agents, the present inventor has developed a pack agent that can moisturize the skin by the blood circulation promoting effect of carbon dioxide gas (Japanese Patent Application No. 59-73503 issue). The inventor of the present invention further conducted various studies in order to obtain a pack agent that can more effectively express the blood circulation promoting effect of carbon dioxide gas, and as a result, the inventors discovered that carbon dioxide gas is adsorbed and contained in aluminosilicate and incorporated into a pack agent. The inventors have discovered that the above object can be achieved and have completed the present invention.

The aluminosilicate used in the present invention can be used in any of amorphous, partially crystalline, and crystalline forms, but crystalline forms are preferred. Specifically, natural aluminosilicates such as analcite and chabazite, and synthetic zeolites commonly referred to by names such as zeolite A, X, and Y are used. Among these, synthetic zeolites represented by the following general formula are preferred as they contain less impurities and other contaminants.

(M2/no) X-A-etOs ・(Slot)y
・(H2O) Z (wherein MFi is a metal atom with a valence of n, X is 0.7 to i, s and y are 0.8 to 10, and z is a number of 0 or more) represented by the above general formula Among the synthetic zeolites, examples of the metal atom represented by M include sodium, potassium, calcium, magnesium, etc. Calcium is preferred from the viewpoint of stability of adsorbed carbon dioxide gas. 2 is preferably 0, that is, one containing substantially no water. Further, the particle size of the aluminosilicate used in the present invention is 0.5 to 100 microns, preferably 1 to 40 microns.

Furthermore, the aluminosilicate may be used in the form of a fine powder with the above particle size, in the form of granules, pellets, etc.
Fine powder is preferred from the viewpoint of effectiveness.

Carbon dioxide gas can be adsorbed and contained in such aluminosilicate by, for example, bringing the aluminosilicate into contact with carbon dioxide. In this case, the aluminosilicate is preferably dehydrated by heat treatment and optimally contains substantially no water. The adsorption is preferably carried out under anhydrous conditions at a carbon dioxide pressure of 0.1
kg/cr1 or more, preferably 1-10 kg/c!
It is done at t. Temperature is below 30℃, preferably 20℃
In the following, although the time is not particularly limited, the reaction is preferably carried out until equilibrium is reached.

The adsorption amount of carbon dioxide gas on aluminosilicate is 2? “Ot.
/100 f aluminosilicate or higher is preferred, and 5 y-CO, /1005' aluminosilicate or higher is particularly preferred.

In order to release the carbon dioxide adsorbed and contained in the aluminosilicate during use of the pack agent, water may be supplied to the aluminosilicate to replace carbon dioxide with water. Specifically, (1) an aluminosilicate adsorbing and containing carbon dioxide gas is deposited on a liquid or solid carrier such as oil, silicone oil, nonwoven fabric, cloth, paper, etc. during use or in advance, and is deposited on the pack area; Examples include a method in which carbon dioxide gas is released by stacking towels or adding water; and (2) a method in which the aluminosilicate is kneaded and mixed with water and applied to the pack area at the time of use.

Among these, the most suitable method is a method using a mixed pack consisting of a first part containing an aluminosilicate adsorbing and containing carbon dioxide gas and a second part containing an aqueous solution of a water-soluble polymer. In this case, examples of the water-soluble polymer compound used in the second agent include polyvinyl ether, sodium alginate, polyvinyl alcohol, vinyl acetate resin, methylcellulose, sodium carboxymethylcellulose, polyvinylpyrrolidone, and carboxyvinyl polymer. can.

This aqueous solution generally contains compounds that can be used in packs, such as humectants, thickeners, alcohol, astringents,
Flavors, pigments, hormones, nutritional supplements such as various vitamins, etc. can be blended as appropriate. The mixed bag agent is applied to the bag site after uniformly blending the first agent and the second agent before use. Generally, the mixing ratio of the first and second agents is 2:
98. It is preferable to set the ratio to 70:30.

In addition, in method (2), when using the pack agent by spreading it on cloth, paper, nonwoven fabric, or other support, attach a release film to the exposed surface of the mixture to form a shape that is easy to apply to the skin. It can also be cut into pieces, and when used, the peeling film can be peeled off and applied directly to the skin surface.

[Effect]

The carbon dioxide gas used in the backing agent of the present invention is:

Aluminosilicate has the effect of promoting blood circulation, and also has the effect of gradually releasing carbon dioxide gas adsorbed thereon by replacing it with water or the like.

〔Effect of the invention〕

The bag agent of the present invention can promote blood flow on the skin surface through the pharmacological action of carbon dioxide gas, thereby significantly increasing the absorption of nutrients contained in the pack agent.

Additionally, as blood flow increases, the removal of waste products and the supply of nutrients through the blood also become more active, making it possible to prevent skin aging. Furthermore, the υ pack can be gently peeled off from the skin surface due to the carbon dioxide gas foaming, and the skin will not be damaged. As a comprehensive effect of these, it also has the advantage of promoting the formation of new epidermal cells.
