[0002]

2. Description of the Related Art Conventionally, the problems to be solved by the invention
Drugs or cosmeceuticals intended for hair nourishment and hair growth use synthetic drugs or natural product extracts having various actions, but they are not effective enough even if added in small amounts. On the other hand, when added in a large amount, it gives an unpleasant stimulus to the adaptation site, and if it is used continuously, dermatitis occurs.

[0003] On the other hand, Hypericum perforatum has been used as an internal medicine for decoction for hemostasis and astringency in Chinese medicine since ancient times, but in recent years, its extract has vasodilatory action and hair-growing / hair-growing action. Became known (JP-A-3-163026).

However, when a hair nourishing and hair-restoring agent is prepared by using only the extract of Hypericum perforatum as a medicinal component, a sufficient effect cannot be obtained. Therefore, it is necessary to add another medicinal component to this. It is difficult to predict the interaction with the medicinal components to be used in combination, and a hair nourishing / hair-growth agent having a sufficient desired effect has not yet been obtained.

Therefore, by combining the extract of Hypericum perforatum with other medicinal components, synergistic hair growth and hair growth,
It has been desired to develop a hair nourishing and hair-growth agent that has a hair loss prevention effect and is highly safe for a long period of time.

[0006]

Further, it may be used after causing precipitation of impurities at a temperature of room temperature or lower and removing it by filtration or the like.

The extract can be used as it is as an active ingredient of the hair nourishing and hair-growth agent of the present invention. However, the extract can be further separated by an appropriate separation means such as gel filtration method, silica gel column chromatography method, reverse phase or It is also possible to fractionate and use a highly active fraction by a normal phase high performance liquid chromatography method.

The Hypericum perforatum extract (a) thus obtained is usually preferably dissolved in water or a solvent such as water-lower alcohol before use. The Hypericum perforatum extract is 0.001 to 10% by weight (hereinafter simply referred to as "%"), particularly 0.03, by dry weight in the hair nourishing and hair-restoring agent of the present invention from the viewpoint of synergistic effect and sensation of scalp. It is preferable to blend 3% to 3%.

It is particularly preferable that the hair nourishing and hair-restoring material of the present invention further contains carbon dioxide gas. It is known that carbon dioxide exists as a CO ₂ molecule when the pH of the solution in which it is dissolved is acidic, and exhibits a vasodilatory action.
Therefore, it is preferable to adjust the liquidity of the hair nourishing / hair-growing material of the present invention containing carbon dioxide to a pH of 7 or less, particularly pH 4.5 to 6.5. It should be noted that the pH of the hair-growth / hair-growth agent is adjusted so that the carbon dioxide gas is pressed into the hair-growth / growth agent and the acidity is further increased when it dissolves in the hair-growth / hair-growth agent, but the final pH is within the above range. As the pH adjuster, for example, organic acids such as citric acid, tartaric acid, lactic acid or salts thereof, or phosphoric acid or salts thereof are preferably used.

In order to mix carbon dioxide into the hair nourishing and hair-growth material of the present invention, other components except carbon dioxide are put in a pressure resistant container, and high-pressure carbon dioxide is sealed therein, sodium hydrogen carbonate or the like in the pressure resistant container. The method of putting a component that generates carbon dioxide gas containing carbonate, generating a carbon dioxide gas by adding it to this and immediately sealing it, or putting dry ice pellets in a container and sealing it is possible. Although adopted, a method of enclosing high-pressure carbon dioxide is particularly preferable.

In this case, part of the carbon dioxide gas is dissolved and mixed in the hair nourishing / hair-growth material of the present invention, and part of the carbon dioxide gas is present as a gas in the container. In the present invention, it is important that carbon dioxide is dissolved and mixed in the hair nourishing / hair-growth agent, and the amount of this carbon dioxide gas is preferably 60 ppm or more. The effect of adding is not obtained. The amount of carbon dioxide mixed can be adjusted by the amount of carbon dioxide injected (press-fit). Generally, the pressure in the container is 1.2 to 8 kg / cm at a temperature of 35 ° C.
² (gauge pressure) is preferable.

In addition to the above-mentioned components, the hair nourishing and hair-restoring agent of the present invention may optionally contain, within a range that does not impair the effects of the present invention, an oily base, a gelling agent, and various other ingredients used in ordinary cosmetics. An emulsifier, a fragrance, an antioxidant such as parahydroxybenzoic acid ester, and a coloring agent such as a dye can be added and blended.

The hair nourishing and hair-growing material of the present invention can be produced by subjecting the above-mentioned essential components and optional components to operations such as mixing according to a conventional method.

EXAMPLES The present invention will be specifically described below with reference to examples, but the present invention is not limited thereto.

Reference Example 7 dry ground (2.44 kg) of whole western Hypericum perforatum was used.
Stir in 0% ethanol at 50 ° C. and filter. The filtrate was concentrated under reduced pressure, water was added, and the mixture was left at 5 ° C. After filtration,
Activated carbon was added to the filtrate and the mixture was stirred at room temperature. The filtrate was concentrated under reduced pressure, and ethanol was added to adjust the concentration. This was left at a lower temperature and then filtered. As a filtrate, 0.68 kg of Hypericum perforatum extract (dry solid content: 30% by weight) was obtained. This Hypericum perforatum extract was used in the following examples.

Examples 1 and 2 Samples having the compositions shown in Table 1 below were prepared. That is, Hypericum perforatum extract was dissolved in a solvent (65% ethanol) to a concentration of 1%, and then component (b) in Table 1 was used.
Was added, and the mixture was sufficiently dissolved and mixed, and Examples 1 and 2 and Comparative Examples 1 to 1 were added.
3 was obtained.

[Table 1]

(Mouse hair growth test) 49 days old C3H
The back hair of 20 heads of 1 / HeNCrj mouse was shaved with an electric clipper and an electric shaver for 2 × 4 cm ² without damaging the skin. Then, from the next day, 20 μl of the above sample was applied to the shaved site once a day for 4 weeks. The group coated with only the solvent was used as a control group. In order to observe hair regrowth, the shaving site was photographed at a constant magnification, and the change over time in the regrowth area ratio (regeneration hair area / shaving area) was measured using an image diffraction device.

The results are shown in Table 2. As is apparent from the comparison of the average value of the regenerated hair area ratio on the 20th day after the start of the test application, the hair-growing agent of the present invention containing the Hypericum perforatum extract and the component (b) of Table 1 in combination was compared with the control and comparative examples. It can be seen that the mouse hair growth effect is extremely large.
