[0002]

2. Description of the Related Art Gray hair is one of the physiological aging phenomena caused by changes in hair matrix pigment cells. There have been many reports of improving ingredients or hair formulations. Among them, components derived from natural products such as plant extracts having a melanocyte activating action or a tyrosinase activity stimulating action on hair roots are considered to be useful as whitening inhibitors or whitening inhibitors because of their excellent safety ( JP-A-11-79951, JP-A-11-79951
139,953, JP-A-7-133288, JP-A-8-26863, and the like.

However, even in these plant extracts,
If a small amount is added, sufficient effects cannot be obtained.On the other hand, if a large amount is added, it may cause unpleasant irritation to the indication site, and if used continuously, dermatitis may occur. Then, it was difficult to obtain a sufficient effect.

[0004] An object of the present invention is to provide a hair cosmetic composition which is excellent in the effect of preventing or improving the generation of gray hair, and which is more excellent in safety and stability.

[0005]

Means for Solving the Problems The present inventors have studied various components of the horsetail, which has an action of preventing or improving white hair, for improving the white hair inhibiting effect, and found that when a specific conditioning component was blended, It has been found that the white hair development inhibitory effect of these plants is significantly enhanced, and that the safety is high for a long period of time.

That is, the present invention provides a hair cosmetic composition containing (A) horsetail extract and (B) a silicone or a cationic polymer.

The hair cosmetic composition of the present invention may be in any dosage form as long as it can be applied to the hair and scalp, but is preferably a dosage form that can be effectively applied. Usually, it is mainly composed of a liquid preparation, and lotions and hair tonics are typical. However, creams, gels, shampoos, rinses, hair foams, hair sprays and the like can also be used. In particular, it is preferable to use an aerosol agent for ease of use. In this case, as a propellant, a combination of two or more of carbon dioxide, LPG, DME, nitrogen gas, and isopentane can be used. It is preferable to contain carbon dioxide gas from the viewpoint of the gray hair prevention effect.

Carbon dioxide gas is the pH of the solution in which it is dissolved.
It is known that when is acidic, it exists as a CO ₂ molecule and exhibits a vasodilator effect. Accordingly, the composition of the present invention containing carbon dioxide has a pH of 7 or less, especially pH 4.5 to 4.5.
Adjustment to 6.5 is preferred. In addition, when the carbon dioxide gas dissolves in the composition, the acidity is further increased. However, if necessary, the final pH may be adjusted so as to be within the above range. this
As the pH adjuster, for example, organic acids such as citric acid, tartaric acid, and lactic acid or salts thereof, or phosphoric acid or salts thereof are suitably used.

To incorporate carbon dioxide into the composition of the present invention,
Other components except carbon dioxide gas are put into a pressure vessel, and high-pressure carbon dioxide gas is sealed in the pressure vessel. A component that generates carbon dioxide gas containing carbonate such as sodium bicarbonate is placed in the pressure vessel, and an appropriate A method of generating a carbon dioxide gas by adding a pH adjuster and sealing immediately, or a method of sealing a dry ice pellet by putting it in a container, etc. are adopted, and a method of sealing a high-pressure carbon dioxide gas is particularly preferable.

In this case, a part of the carbon dioxide gas is dissolved and blended in the composition, and a part thereof is present as a gas in the container. In the present invention, it is important that the carbon dioxide is dissolved in the composition, and the compounding amount is preferably 60 ppm or more. Can be adjusted by the amount of carbon dioxide gas injected (injected). In general, it is preferable that the pressure in the container be 1.2 to 10 kg / cm ² (gauge pressure) at a temperature of 35 ° C. Especially 4.5-1
It is preferable that the pressure be 0 kg / cm ² (gauge pressure).

The hair cosmetic composition of the present invention can be produced by subjecting the above essential components and optional components to operations such as mixing according to a conventional method.

The hair cosmetic composition of the present invention thus obtained can significantly reduce the amount of the active ingredient used since the gray hair inhibiting effect of horsetail is reduced, so that the safety can be reduced with less side effects. It can be a high gray hair control hair cosmetic.
