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 spherical powder. The present invention relates to a cosmetic that is excellent in lightness, smoothness, and melt-filling property.

[0002]

2. Description of the Related Art Conventionally, various powders have been blended in cosmetics for the purpose of covering the skin and improving the feeling of use. In addition, organic pigments, inorganic pigments, and pearlescent agents are added. Alternatively, a wide range of colors is produced by adding a lame agent or the like. In recent years, a sparkling and brilliant atmosphere that emphasizes pearl and lame has become popular, and those with impact have become popular,
Attempts have been made to incorporate large amounts of pearl and lame agents into cosmetics.

However, if a large amount of a pearl or lame agent is blended, there are disadvantages in the feeling of use such as poor spreadability and lack of smoothness of the cosmetic, and a defect in filling due to an increase in viscosity. There were restrictions on the blending amounts.

[0004] In order to improve the feeling of use of cosmetics, it is conceivable to mix various powders in large amounts. It has drawbacks such as the need to reduce the amount of the pigment, and it is difficult to achieve a brilliant and brilliant atmosphere that emphasizes the pearly feeling and the glittery feeling.

[0005]

Therefore, there has been a demand for the development of a cosmetic which has excellent glitter, brightness and shine, which is not present in conventional cosmetics, and which is light, smooth, and excellent in melt-fillability. .

[0006]

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 certain shape in which the surface of a glass flake is coated with a metal oxide and a spherical powder. By using the combination, it was found that a cosmetic having unprecedented shine, lighter spreadability, smoothness, and excellent melt filling properties was obtained, and the present invention was completed.

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 spherical powder.

[0008]

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.

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 for the glass flakes may have any composition as long as it contains silica in the above-mentioned 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,
When sufficient brilliancy is not obtained, and on the other hand, when it is larger than 700 μm, the texture becomes rough and the shine 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, and 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 brightness is too strong, which is not preferable 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, it is possible to obtain a pearlescent pigment exhibiting a luster similar to a pearl in appearance, but the metal oxide used for this coating is titania (TiO _2). ), 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.

The spherical powder of the component (b) used in the present invention is not particularly limited as long as it is a spherical powder usually blended in cosmetics. Spherical powders satisfying the condition that the ratio is 1 to 0.8 are mentioned.

It may be one subjected to a surface treatment using oil, fat, hydrocarbon, or the like. Also,
As the component (b), one or more kinds can be used as necessary.

The average particle size of the component (b) is, for example, 1% when measured with a laser diffraction type particle size distribution analyzer.
５０50 μm, preferably 5 μm-3
It is preferably 0 μm. If the average particle size is within this range, there is no roughness and light growth can be provided.

The cosmetic of the present invention can be produced by mixing the above components (a) and (b) according to a conventional method. The amount of the pearlescent pigment which is the component (a) used in the present invention is 0.05 to 50 in the cosmetic of the present invention.
