Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an oily cosmetic composition having a vivid brilliant effect, a cosmetic effect such as highlighting a site to be used, an excellent persistence thereof, and a good use, safety and stability. .

[0002]

2. Description of the Related Art Conventionally, cosmetics such as lipsticks, lip glosses, lip bases, lipstick overcoats, lip balms, eye colors, cheek colors, foundations, and the like include oils such as solid oils, semi-solid oils, liquid oils, and coloring agents. Attempts have been made to produce various functions and color tones by changing the blending amount of powder components such as pigments, brilliant pigments and extender powders. In particular, a wide range of color tones has been produced by blending an organic pigment, an inorganic pigment, a glitter pigment, a lame agent, and the like. In recent years, glittering and brilliant atmospheres with a particular emphasis on pearl and lame have become popular, and there is a strong tendency to prefer impactful ones.

[0003] The current brilliant pigments such as pearlescent agents and lame agents are no longer able to adequately cope with such trends and fashions reflecting such trends, and new pigment materials which are more brilliant and brilliant are required. It has come to be. And the pigment material has not only good shine and glitter but also good dispersibility and stability when blended in cosmetics, as well as sensibility and usability such as spread and smoothness when applying. It is also required to be excellent.

[0004]

Accordingly, the present invention has excellent shine and glitter, shows excellent dispersibility and stability when incorporated into cosmetics, and has a good spreadability when applied. Another object of the present invention is to find a new pigment material having excellent functionality such as smoothness and the like, and to provide an oil-based cosmetic using the same.

[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 an ethylene-propylene copolymer Oily cosmetics obtained by combining with and / or polyethylene wax have an unprecedented brilliance, and can be used as a cosmetic effect such as creating a three-dimensional appearance by highlighting the use site, They have found that the cosmetic effect lasts, and have completed 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 an oil-based cosmetic comprising a pearlescent pigment having an aspect ratio of 5 to 500 μm and (b) an ethylene / propylene copolymer and / or a polyethylene wax.

[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 also 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,
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, 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 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, 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, an arbitrary 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.

As the ethylene-propylene copolymer and / or polyethylene wax used as the component (b) in the present invention, any of those generally used in cosmetics can be used. Is 75 ~
Those having about 120 ° C. are preferred. PER as a commercial product
FORMALENE500, PERFORMALENE
655, EP-700 (both Baker Petrol)
ite). One or more of these can be used as needed.

The oily cosmetic of the present invention can be produced by mixing the above components (a) and (b) according to a conventional method. The compounding amount of the component (a) in the cosmetic of the present invention is preferably about 0.1 to 40% of the total composition, and more preferably 1 to 1 from the viewpoint of the appearance of brilliancy, usability, and long-lasting makeup. More preferably, it is 20%. The amount of the component (b) used in the present invention is 0.1 to 30 in the total composition in view of pigment dispersibility, usability, stability over time, and the like.
