Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to improvement of cosmetics, particularly cosmetics containing a pearl pigment.

[0002]

2. Description of the Related Art Conventionally, for the purpose of imparting various optical properties such as three-dimensional effect, transparency and luster, pearl pigments typified by mica titanium coated with titanium oxide having a certain thickness in mica have been used in foundations and foundations. It is included in cosmetics such as makeup base. Since such a pearl pigment is coated on the base pigment, visible light reflected at both interfaces of the coating layer interferes with each other, and a colorful interference color in which visible light of various wavelengths is emphasized depending on the viewing angle. It has a special characteristic such as exhibiting the above-mentioned properties, and by blending it with a cosmetic material, various optical characteristics described above are imparted. Specific examples of pearl pigments used include timylon super red and timylon super blue (manufactured by MERCK). When the average particle size and particle size distribution of these pearl pigments were measured by a particle size distribution measuring device using a light diffusion method, the average particle size was around 20 μm, and about 20% of the particles having a particle size of 45 μm or more were present. Was there.

[0003]

However, when particles having a large particle size such as these general pearl pigments are contained, the pearl pigment having a large particle size causes an excessively flickery feeling, resulting in a cosmetic composition. In particular, when added to a base makeup cosmetic such as a foundation, a tingling sensation becomes conspicuous and the finish becomes unnatural. The present invention has been made in view of the above prior art, and an object of the present invention is to provide a cosmetic composition which eliminates an excessive flicker feeling while maintaining imparting optical properties to the finish of a pearl pigment.

[0004]

Means for Solving the Problems As a result of intensive studies for achieving the above-mentioned object, the present inventors have found that when a conventionally used pearl pigment is pulverized with a wet medium stirring mill, its particle size distribution is Among them, it was found that the large particle size portion was selectively ground. Furthermore, when the pulverized liquid was blended into a cosmetic, it was found that while giving the optical characteristics to the finish of the pearl pigment, the flicker feeling that is the cause of the unnatural finish is greatly reduced. The invention was completed. That is, the cosmetic according to the present invention is characterized by containing a pearl pigment pulverized by using a wet medium stirring mill.

In the cosmetic, it is preferable that the pearl pigment before pulverization has an average particle size of 10 to 30 μm. Further, in the cosmetic, particles having a particle size distribution of 50 μm or more in the particle size distribution of the pearl pigment after the pulverization treatment are 1
It is preferable that the content is 5% or less, and the average particle size of the pearl pigment after the pulverization treatment is 5 μm or more. In the cosmetic, it is preferable to add a pulverized liquid obtained by pulverizing a pearl pigment using a wet medium stirring mill. Also,
In the cosmetic, it is preferable to grind the pearl pigment in a manufacturing process using a wet medium stirring mill. Further, in the cosmetic, it is preferable to use beads as a medium used for a wet medium stirring mill.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail based on embodiments. The cosmetic of the present invention contains a pearl pigment ground using a wet medium stirring mill. Then, the pearl pigment having an average particle diameter of 10 to 30 μm before the pulverization treatment is wet pulverized, and 15% or less of particles having a particle diameter of 50 μm or more are 15% or less in the particle size distribution of the pearl pigment after the pulverization treatment, and the pearl pigment after the pulverization treatment. Is characterized by having an average particle diameter of 5 μm or more. In this way, the pearl pigment is pulverized to a certain extent by wet pulverization, and while maintaining the optical properties of various finishes such as the three-dimensional effect, transparency, and gloss of the pearl pigment, the pearl pigment is caused by the large particle size component. It is possible to obtain a cosmetic product free from excessive flicker.

When the particle size distribution of the pearl pigment after pulverization is 15% or more in the particle size distribution of 50 μm or more, a tingling sensation remains as strong as before pulverization, and the finish is unnatural even when used in cosmetics. Is. Further, if the pearl pigment after the pulverization process is excessively pulverized and the average particle size of the pearl pigment after the pulverization process is less than 5 μm, the interference light originally possessed by the pearl pigment is almost eliminated, and the desired optical characteristics are obtained. It is not preferable because it will not be possible.

The pearl pigment used in the present invention is not particularly limited as long as it is usually used in cosmetics. For example, titanium mica, iron oxide-coated mica, lower titanium oxide-coated mica titanium, and photochromic mica titanium. Etc.

Further, in the present invention, the pearl pigment is wet pulverized by a wet medium stirring mill. Here, the wet pulverization is a method of pulverizing using a solvent such as water, alcohol, hexane, toluene, methylene chloride, glycerin, silicone or the like.

However, it is not limited as long as the object of the present invention can be achieved. As the beads used for the wet medium stirring mill, beads made of glass, alumina, zirconia, steel, flint stone, etc. can be used.

Regarding the mixing and pulverization of the pearl pigment in producing the cosmetic of the present invention, either of the following two methods is possible. That is, a method may be used in which a pulverized liquid obtained by separately pulverizing pearl pigments using a wet medium agitation mill is prepared, and the pulverized liquid is mixed with other compounding ingredients of the cosmetic, or each manufacturing step of the cosmetic is performed. In the manufacturing process using a wet medium agitation mill, the pearl pigment may be pulverized with other compounding ingredients in a wet medium agitation mill.

The wet pulverized product of the pearl pigment of the present invention may be further subjected to surface treatment such as metal soap treatment, silicone treatment, fluorine compound treatment such as perfluoroalkyl phosphate ester, and oil treatment.

As is clear from Table 1, the proportion of particles having a particle size of 50 μm or more to all the particles gradually decreased as the pulverization time increased. And particle size 50 μm
In Test Examples 3 to 5 in which the ratio of the particles was reduced to 15% or less, the flicker feeling was eliminated, and the lustrous feeling was maintained to a satisfactory degree. The results reflect the measurement results even when actually applied to the skin. On the other hand, in Test Examples 1 and 2 in which the proportion of particles having a particle diameter of 50 μm or more was 15% or more, there was a sufficient glossiness, but an excessive flickeriness. In addition, a strong tingling sensation was observed even when actually applied to the skin. Further, as in Test Example 6, when the pulverization time was too long, the pulverization proceeded extremely, and the average particle size was significantly reduced. When the average particle diameter was less than about 5 μm, there was no flicker, but no satisfactory feeling was obtained at all. The measurement results shown in Table 1 were almost in agreement with the sensory evaluation described below.
