Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cosmetic using a pearlescent pigment in which the surface of a glass flake is coated with a metal oxide, and a water-soluble polymer. The present invention relates to a cosmetic composition that has an unprecedented luster due to its lustrous pearl luster, has a transparent feeling, and has excellent usability.

[0002]

2. Description of the Related Art Conventionally, cosmetics have been produced by blending an organic pigment, an inorganic pigment, a pearl agent, a lame agent and the like to produce a wide color tone. In recent years, glittering and glittering atmospheres, especially emphasizing pearly and lame feelings, have become popular, and those with impact have become popular. Have been tried.

[0003] As described above, when a large amount of a pearl agent or a lame agent is blended in a cosmetic, various dispersants are blended in order to maintain the stability of the system itself. However, in order to stably maintain the system with only the dispersant, a large amount of the dispersant must be blended, resulting in a disadvantage that the cosmetic functionality, such as spreadability and smoothness, and the usability are significantly reduced. Was. In addition, even if a large amount of pearl and lame agents are blended in the cosmetic in such a manner, there is also a problem that it is not possible to sufficiently cope with current consumer preferences and trends.

[0004]

Accordingly, the development of a cosmetic composition which is excellent in dispersion stability of the system itself, has a brilliant pearl luster, has an unprecedented shine, is transparent, and has excellent usability. Was desired.

[0005]

Means for Solving the Problems The inventors of the present invention have conducted intensive studies to solve the above-mentioned problems, and as a result, have found that a pearlescent pigment having a predetermined shape in which the surface of a glass flake is coated with a metal oxide and a water-soluble polymer are used. By using a combination of these, it was found that a cosmetic having excellent dispersion stability, an unprecedented shine and an excellent feeling upon use was obtained, and that the use thereof could also produce a transparent feeling, thereby completing the present invention.

That is, according to the present invention, the following components (a) and (b): (a) the surface of a glass flake is coated with a metal oxide;
Average thickness is 0.1 to 3.0 μm, average particle size is 1 to 700
The present invention provides a pearlescent pigment having an aspect ratio of 5 to 500 μm and (b) a water-soluble polymer.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION The pearlescent pigment of the component (a) used in the present invention comprises glass flakes as a base material and the surface thereof is coated with a metal oxide. Here, the glass flake refers to a silica (SiO ₂ ) of 45 to 75% by mass.
It is obtained by pulverizing a glass film containing about (hereinafter simply referred to as “%”). Examples of the glass flake include those produced by a melting method. More specifically, the glass flakes are described in JP-B-41-17148.
And those manufactured by the method described in JP-B-45-3541.

[0008] The glass flakes obtained by the above method are:
Since the molten glass having a free surface is solidified by cooling, its surface is very smooth, and since it is amorphous and has no cleavage, there is almost no step on its surface. Also, since it has some flexibility compared to silica glass containing 80% or more of silica, it is hard to be crushed and is suitable for blending into cosmetics.

In terms of shape, the average thickness is 0.1 to 3.
A 0 μm glass film was pulverized and classified, and the average particle diameter was 1
Glass flakes having a thickness of 700 μm, an average thickness of 0.1 to 3.0 μm, and an aspect ratio of 5 to 500 can be obtained.

The glass used as the raw material of the glass flakes may have any composition as long as it contains silica in the above range and can be melt-molded.
S glass, E glass, C glass and the like are exemplified, but C glass is particularly preferable because a step is hardly generated on the surface and smoothness is easily obtained.

The pearlescent pigment of the component (a) used in the present invention has an average thickness of 0.1 to 3.0 μm and an average particle size after the surface of the glass flake is coated with a metal oxide. Is 1 to 700 μm and the aspect ratio is 5 to 500. Regarding the average thickness, it is difficult to make the glass flakes thinner than 0.1 μm due to the manufacturing technology, while if the average thickness is larger than 3.0 μm, the glass flakes have a rough feeling and are not preferable in touch.

When the average particle size is less than 1 μm,
If sufficient glitter is not obtained, and if it is larger than 700 μm, the texture becomes rough and the gloss is too strong to be unnatural, which is also unsuitable.

Further, when the aspect ratio is less than 5, the feeling of spreading on the skin is poor, while when it is more than 500, the feeling of fitting to the skin is poor and the appearance of the metal coating is poor. The gloss is too strong, which is not preferred for the present invention. The “aspect ratio” indicates a value obtained by dividing the average particle size of glass flakes by the average thickness.

By coating this glass flake with a metal oxide, a pearlescent pigment exhibiting a luster similar to that of a pearl in appearance can be obtained. As the metal oxide used for this coating, titania (TiO _{2) is used.} ), Zirconia (Z
rO ₂ ) and metal oxides such as iron oxide. A method of forming a coating film using a metal oxide may use a known technique. For example, a method described in JP-B-43-25644 and JP-A-47-34529 can be used. Specifically, glass flakes are suspended in a titanyl sulfate solution or a titanium tetrachloride solution, and titania is precipitated by raising the temperature of the solution to form a coating on the glass flakes. However, the present invention is not limited to this method, and there is no particular limitation as long as a thin film can be provided on the glass flake.

In the pearlescent pigment of the component (a) used in the present invention, any color tone due to interference can be exhibited by controlling the thickness of the coating on the glass flake. The thickness of this coating is 20 to 250 n
m is preferred. When the thickness is less than 20 nm, glitter is hardly exhibited, while when it is greater than 250 nm, a glittering appearance having an appropriate transparency may not be obtained. In addition,
Since the coating has such a small thickness, the thickness of the glass flakes and that of the pearlescent pigment are not much different.

On the other hand, the water-soluble polymer of the component (b) used in the present invention is not particularly limited as long as it is used for cosmetics.
