DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cosmetic containing an unpaired electron-removing substance, and more particularly to a liquid or cream which remarkably promotes the beautiful skin effect of a germanium roller by the action of the unpaired electron-removing substance. The present invention relates to a state-of-the-art cosmetic.

[0002]

2. Description of the Related Art In recent years, it has been known that active electrons activate living cells to promote metabolism and blood circulation of the skin. (Patent No. 93112)
No. 6, Utility Model Registration No. 1920098). This roller for beautiful skin is a roller provided with a thin layer of germanium on the surface, and when rubbing the surface of the skin with this, active electrons are transferred from germanium to the skin, and the action of the active electrons causes the metabolism of the skin and The blood circulation is promoted, and the wastes deposited on the skin are removed, and a beautiful skin effect is exhibited. However, since this beautiful skin effect is gradually exerted, it is necessary to patiently rub the skin surface with the roller for a long period of time.

[0003] The present inventors, when first contacted with the skin,
As a germanium roller for beautiful skin that emits a large amount of active electrons and enhances the skin's activation effect, germanium impurities containing very small amounts of impurities such as phosphorus, arsenic, antimony, and bismuth around the core material made of ferrite magnets We have developed a germanium roller for beautiful skin, in which a semiconductor layer is provided, and a part of the surface is covered with a conductor having a lower Fermi level than germanium, particularly a metal thin film such as platinum or palladium. Japanese Patent Application No. 1
0-39133).

[0004]

DISCLOSURE OF THE INVENTION The present invention is directed to a liquid or cream for promoting the transfer of active electrons from the roller to the skin by applying it to the skin in order to further enhance the effect of the germanium roller for beautiful skin. The purpose of the present invention is to provide a cosmetic composition.

[0005]

Means for Solving the Problems The present inventors have conducted various studies to improve the beautiful skin effect of the germanium roller. As a result, when the germanium roller rubs the skin, it contains an unpaired electron removing substance. It has been found that applying a liquid or creamy cosmetic to the skin promotes a beautiful skin effect.

In particular, this promoting effect is due to the fact that a part of the surface of the germanium layer containing a small amount of impurities such as phosphorus and arsenic, which has a large transfer of active electrons to the skin, has been developed by the present inventors. When applied to a germanium roller coated with, palladium, gold, etc., it was found that the effect was remarkably exhibited. The present invention has been completed based on such findings.

[0007] That is, the present invention provides a liquid or creamy cosmetic containing an unpaired electron removing substance.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION The action of the cosmetic roller of the present invention for promoting the beautiful skin effect of a germanium roller is described below.
This can be explained with reference to the model diagram of FIG. FIG.
FIG. 3 is a model diagram for explaining movement of active electrons between a germanium roller and an unpaired electron removing substance (hereinafter, sometimes referred to as a radical scavenger). In this figure, electrons e move from the germanium layer 2 containing a small amount of impurities into the skin 3 in contact with the germanium roller via the conductive film 1. Holes are generated in the germanium layer 2 from which the electrons e are released, and have a positive charge. The holes immediately react with the unpaired electron removing substance in the cosmetic applied to the skin 3. Then, the positive charge is lost, the state returns to the original state of germanium, and the electron e is emitted again. That is, according to the cosmetic of the present invention,
The electron transport system in the living body by the germanium roller is promoted, and the beautiful skin effect is significantly improved.

The unpaired electron-removing substance used in the cosmetic of the present invention is a substance which immediately reacts with the hole generated in the germanium layer to lose the positive charge of the hole as described above. Particularly preferred are (1) mono- or polyphenols, (2) reducing monosaccharides or reducing polyhydric alcohols, and (3) organic ionic compounds having an oxidizable sulfur atom in the molecule. It is.

The mono- or polyphenols (phenolic radical scavenger) of the above (1) are not particularly limited as long as they supply electrons to holes immediately to become quinone-based compounds. Any of these may be used. For example, a butylated hydroxyanisole represented by the formula (I) reacts with a hole to form a compound represented by the formula (I)
The quinone compound represented by I) is obtained.

Examples of natural phenolic radical scavengers include green tea, persimmon leaf tannins, gerinin tannins, flavonoids quercetin, reishi extract, and carrot extract.

As the reducing monosaccharide or reducing polyhydric alcohol of the above (2), D-aldoses of hexamonosaccharide or hexahydric sugar alcohols are particularly effective as radical scavengers of germanium holes. It is preferred because it works. Hexasaccharide D-aldoses include D-glucose, D-talose, D-mannose, and D-galactose, which supply electrons to germanium holes and simultaneously react with oxygen in the air. In the form of oxidized carboxylic acids. For example, D-glucose represented by the formula (III) reacts with holes to become D-gluconic acid represented by the formula (IV).

The hexahydric sugar alcohols include galactol, D-sorbitol, D-mannitol and the like, which supply electrons to the holes of germanium and, at the same time, convert primary alcohol groups by oxygen in the air. Oxidized to aldehyde groups and carboxylic acid groups. Further, examples of the organic sulfur compound having an oxidizable sulfur atom in the molecule (organic sulfur radical scavenger) of the above (3) include, for example, an amino acid having an oxidizable sulfur atom in the molecule, an amino acid condensate, and an amino acid condensate thereof. An initial oxide can be preferably mentioned.

Examples of such organic sulfur radical scavengers include cysteine (V) and glutathione (VI) having a thiol group, methionine (VII) having a sulfide bond, and cystine (VIII) which is an oxidized condensate of cysteine. And the like.

[0017]

In particular, divalent organic sulfur compounds have high reactivity with radicals and have a large function as a radical scavenger of germanium holes. Cysteine (V)
Is converted to cystine (VIII) in which two molecules are linked by a disulfide group by reacting with germanium holes. This cystine (VIII) is represented by the following compound (IX):
While changing to (X), one molecule exhibits a function as a radical scavenger with a high capacity.

As a measure of skin aging, there is a moisture retention function of the stratum corneum forming the outermost layer of the skin. The moisture retention function of the skin by using this cosmetic cream and a germanium roller was determined. Choose 10 men between the ages of 30 and 40,
A three-week test was conducted in the harsh winter of February when the skin was roughest.
Five persons in Group I applied cream to the face and rubbed the surface of the face with a germanium roller twice in the morning and evening for 10 minutes. Group II 5
The person rubbed the face of the face with only the germanium roller without applying the cream. After 3 weeks, the amount of water in the keratin of the epidermis of each person is measured by high-frequency electrical conductivity,
When the average value of five persons in each of the groups I and II was determined, the electric conductivity of the group I was 5.5 μΩ, and the electric conductivity of the group II was 4.5 μΩ. The results show that the skin that has been coated with the beauty cream and rubbed with the germanium roller has a high moisture retention function in the stratum corneum. Group I, II
For the group, the ratio of the high-frequency electrical conductivity before the treatment and after the treatment for 3 weeks was determined.
The effect of the treatment is also higher when the beauty cream is used in combination with the effect of increasing the water retention function.
