Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair cosmetic which can temporarily change the color of the hair, and more particularly to a hair cosmetic which contains titanium mica while giving the color a natural tone. The present invention relates to a hair cosmetic that can be changed.

[0002]

2. Description of the Related Art Conventionally, permanent hair dyes (hair color, bleach and color) have been used as hair cosmetics for changing the color of hair, from the viewpoint of the persistence of the changed color.
A bleaching agent (bleach), a semi-permanent hair dye (hair manicure), and a temporary hair dye are used.

[0003] Among them, when a permanent hair dye, a semi-permanent hair dye or a bleaching agent is used, problems such as damage to the hair and staining to the skin are likely to occur. It is difficult to handle for treatment,
There is a problem that it is practically impossible to immediately restore the color tone when it is changed to an unintended color tone.

On the other hand, when a temporary hair dye is used, there is no damage to the hair and no staining to the skin, and the temporary hair dye attached to the hair is easily washed off by shampooing the colored hair. There is an advantage that the original color tone can be restored.

[0005] Recently, as one type of such a temporary hair coloring agent, a hair cosmetic in which titanium oxide having high hiding power, which has long been used in cosmetics and hair products as a pearl luster imparting agent, is compounded in an alcohol-based solvent. Japanese Patent Application Laid-Open Nos. 58-124713 and 62-4219;
-121208). When a hair cosmetic containing such mica titanium is applied to hair, the hair can be colored brown, and the colored hair can be easily returned to the original hair tone by shampooing. .

[0006]

However, in the case of the conventional hair cosmetics containing titanium mica, not only the hair is colored, but also the hair is given a strong pearly feeling, which is a problem in daily use. There was a problem that it was difficult to use.

An object of the present invention is to solve the above-mentioned problems of the prior art, and to make it possible to color hair with a natural feeling when hair cosmetics containing titanium mica are applied to hair. The purpose is to:

[0008]

DISCLOSURE OF THE INVENTION The present inventors have completely considered the relationship between the particle size of titanium mica and the glittering feeling that mica titanium imparts to hair in conventional hair cosmetics containing titanium mica. Note that if the proportion of titanium dioxide with a relatively large particle size in the total amount of titanium mica used is small, the hair color will be natural and will not give the hair a glittering feeling. Can be changed, and the present invention has been completed.

That is, the present invention relates to a hair cosmetic containing titanium mica, which has a particle diameter of 20 μm in the total amount of titanium mica.
Provided is a hair cosmetic characterized in that the ratio of the above titanium mica is 10% by volume or less.

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail.

The hair cosmetic composition of the present invention contains mica titanium. The reason for using titanium mica is as follows.

That is, in general, mica titanium has a maximum dimension of about several μm to about 100 μm and a thickness of about 0.05 to 1 μm.
Flaky natural mica (Mica, biotite, phlogopite, etc.)
Also, the maximum dimension is about 0.1 to about 50 μm and the thickness is about 0.0
The surface of a synthetic mica of 5 to 50 μm is coated with a titanium dioxide layer. Such mica titanium itself has a white appearance, but develops interference colors such as yellow, red, blue, and green depending on the thickness of the titanium dioxide layer. Therefore, by mixing mica titanium into hair cosmetics,
This is because when the cosmetic is applied to black hair, the mica titanium adhered to the hair surface develops a very vivid color against a black surface.

By the way, the particle size referred to for titanium mica varies depending on the maximum size measured by a microscope or the like or the average value obtained by a light scattering method. The particle size of titanium means a value obtained by the Coulter method. The particle size distribution by the Coulter method can be easily measured, for example, by using a Coulter Multisizer 020487 (with an aperture of 100 μm in diameter) manufactured by Coulter Co., Ltd. as a particle size measuring device. For the calibration, a monodispersed silica latex can be used.
However, in order to measure without aggregating titanium mica particles,
It is necessary to dilute with a surfactant solution (for example, a 0.03% aqueous solution of polyoxyethylene alkyl ether) and perform measurement after sonication.

Generally available titanium mica has a particle size of 1-2 μm.
m and a relatively large particle diameter of 20 μm or more. According to the findings discovered by the present inventors, it is a relatively large particle diameter of 20 μm or more that strongly imparts a sparkling pearly feeling to hair, and moreover, titanium mica having a particle diameter of 20 μm or more in the total amount of mica titanium. Is more than 10% by volume.

Therefore, in the hair cosmetic of the present invention,
The proportion of titanium mica having a particle size of 20 μm or more in the total amount of titanium mica contained is controlled to 10% by volume or less, preferably 7% by volume or less, more preferably 5% by volume or less, and further preferably 1% by volume or less. Therefore, when the hair cosmetic composition of the present invention is applied to hair, the color tone of the hair can be changed in a natural shade without giving the hair a glittering pearly feeling.

The titanium oxide structure of mica titanium is classified into rutile type and anatase type. The rutile type, which has a high refractive index and excellent reflectivity, has a larger color change and a colorful hair. It is preferable because it becomes a color.

As a method for forming rutile type titanium oxide on the surface of mica, a method using tin oxide (US Pat. No. 403)
8099 and 4086100), a method using iron and at least one of calcium oxide, magnesium oxide and zinc oxide (JP-A-7-31646).
No. 4) is known, but the latter method is more preferable from the viewpoint of safety.

The titanium mica produced by the latter method contains iron and at least one of calcium oxide, magnesium oxide and zinc oxide. Here, if the content of iron in mica titanium is too small, the interference color of mica titanium is not sufficient, and if it is too large, mica titanium changes to light brown, and the color change when applied to hair becomes beautiful. The amount is preferably 0.125 to 1% by weight based on the weight of the mica particles coated with titanium dioxide. Further, if the content of at least one of calcium, magnesium and zinc in titanium mica is too small, formation of rutile type titanium dioxide becomes insufficient and color change and gloss when applied to hair become poor, so Preferred is at least 0.05% by weight based on the weight of the mica particles coated with titanium.

As titanium mica used in the present invention, various titanium mica which satisfies the condition that the ratio of particles having a particle size of 20 μm or more is 10% by volume or less can be used. For example, titanium mica simply coated with titanium dioxide, red mica-coated mica titanium, zinc oxide-coated mica titanium, konjo coated mica titanium, carmine-coated mica titanium, black iron oxide-coated mica titanium, red 226 coated mica titanium, barium sulfate Examples include colored mica titanium such as coated mica titanium, and colored mica titanium having a lower titanium oxide layer as disclosed in JP-A-5-43417.

Specific examples of titanium mica used in the present invention include, for example, a commercially available product,
enco Satin Gold (the ratio of particles having a diameter of 20 μm or more is 0.1% by volume).

As titanium mica, in order to improve its stability and dispersibility in hair cosmetics, for example, silicone oils, aliphatic metal salts, alkyl phosphoric acids, alkali metal salts or amine salts of alkyl phosphoric acids, N-mono long chain (C8 ~
C22) An aliphatic acyl basic amino acid or a fluorine compound having a perfluoroalkyl group that has been subjected to a surface hydrophobic treatment can be used.

If the content of titanium mica in the hair cosmetic composition of the present invention is too small, the change in hair color is small, and if it is too large, it becomes unpleasant and unpleasant, so that it is preferably from 0.5 to 20% by weight, more preferably. Is 1 to 15% by weight, more preferably 2 to 10% by weight.

In addition, the hair cosmetic of the present invention is desired to be in the form of an aerosol in consideration of the form of use. In such a case, it is preferable to include a propellant in addition to titanium mica. Such propellants include liquefied petroleum gas (LPG), dimethyl ether, carbon dioxide,
