Description

Impression control agent

The present invention relates to an impression control agent which can express various impressions of the skin.

As a cosmetic applied to the entire face, a pre-makeup agent, a foundation, and the like are used for the purpose of protecting the skin from damage such as ultraviolet rays or covering skin defects caused by unevenness or unevenness of color. On the other hand, as a person who changes the face impression, there are cosmetics such as eye shadow and blush applied to the skin. In order to adjust the appearance of the skin and achieve the impression of the target, the conventional makeup is used continuously in the series of makeup and the latter.

Further, Patent Document 1 proposes a cosmetic composition comprising: a first cosmetic containing a powder component having a specific hue and chroma, and a ratio of a specular reflected light intensity to a diffuse reflected light intensity; and a second cosmetic; The cosmetic material contains a powder component having a hue, a chroma, and a ratio of the intensity of the specular reflected light to the intensity of the diffuse reflected light, which is different from the first cosmetic, and is used to superimpose the first cosmetic material and the second cosmetic material. .

However, there is still no known cosmetic material which can express various skin impressions by applying one agent to the entire face.

On the other hand, the foundation is mainly used for the purpose of masking the unevenness of the skin such as black squad and squad, and the skin defects such as acne scars and pores. In recent years, consumers have not only stopped adjusting their skin tone, but also expect to be able to express the foundation of their skin more beautifully.

In the foundation, an inorganic pigment such as titanium oxide, iron oxide, iron blue, blue or chrome oxide, or an organic pigment such as red 201, yellow 401, blue 1 or green 3 is used as the colorant. When such a coloring pigment is used, particularly in the case of coloring a skin color, if a coloring pigment having a sufficient coloring power is blended, the light absorption of the coloring pigment will result in a dullness of the makeup and a doll like a doll. The feeling of makeup.

Therefore, in order to achieve a feeling of transparency and a three-dimensional finish, a method of using a pearl pigment represented by mica titanium has been proposed (Patent Document 2, Patent Document 3, and Patent Document 4). However, the use of only pearl pigments gives a feeling of transparency and three-dimensional finish, but it is not enough to adjust the unevenness and unevenness of the skin and to express various skin impressions.

(Patent Document 1) Japanese Patent Laid-Open Publication No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. Open bulletin 2005-97218

The present invention provides an impression control agent for skin, which is measured by the method 1 for each of the chroma C ^* ab(0) and C ^* ab(45) measured by an incident light angle of 45°, an acceptance angle of 0°, and 45°. The relationship is C ^* ab(45)-C ^* ab(0)>0, and the brightness L ^* measured by the measurement method 2 is 30 or more, the hue angle h is 0° to 90°, and the chroma C ^* ab is 5. the above.

(Measurement Method 1) The composition was uniformly applied to black artificial leather to be 8 mg/100 cm ² , and the color value defined by the CIE 1976 L ^* a ^* b ^* color system was measured using a variable angle colorimeter.

(Measurement Method 2) The composition was placed in a cell, and the color value defined by CIE1976L ^* a ^* b ^* was measured on the surface thereof using a colorimeter.

The present invention relates to an impression control agent for a skin which can express various skin impressions by applying one agent to the entire face.

The inventors of the present invention have found that when a composition having specific optical characteristics and an appearance color is applied to the entire face, various impressions of the skin can be expressed.

The impression control agent of the present invention can express various impressions of the skin by applying it to the entire face, and can obtain a bright and transparent feeling.

In addition, when it is used as a foundation, when the coating is applied, the unevenness of the skin color and the unevenness of the skin can be made inconspicuous, and a clear and translucent feeling can be obtained, and various impressions of the skin can be expressed.

In the impression control agent of the present invention, first, the relationship between the respective chroma C ^* ab(0) and C ^* ab(45) measured by the measurement method 1 at an incident light angle of 45°, a light receiving angle of 0°, and 45° is C ^* ab(45) - C ^* ab(0) > 0, preferably C ^* ab(45) - C ^* ab(0) > 1.5.

This C ^* ab(45)-C ^* ab(0)>0 means that the color of the surface reflected light is thicker than the diffuse reflected light, but when it is 0 or less, the skin impression cannot be changed.

Here, in the measurement method 1, first, the composition was taken out on a black artificial leather using a sponge, and lightly uniformly applied to the artificial leather by a method of 8 mg/100 cm ² . This is measured using a variable angle measuring instrument (for example, a variable angle spectrometry system (manufactured by Murakami Color Research Laboratory, GCMS-4)) at an incident light angle of 45° and a light receiving angle of 0° and 45°. The two reflected lights at this time are defined by the CIE1976L ^* a ^* b ^* color system, and the chroma of the light receiving angle of 0° is taken as C ^* ab(0), and the chroma of the light receiving angle of 45° is taken as C ^* ab ( 45), find C ^* ab (45) - C ^* ab (0).

Further, in the impression control agent of the present invention, the lightness L ^* measured by the measurement method 2 is 30 or more, the hue angle h is 0 to 90, and the chroma C ^* ab is 5 or more.

In the measurement method 2, the composition is first placed in an analysis tube, and a color value defined by the CIE1976L ^* a ^* b ^* color system is measured for the surface thereof, that is, the brightness L ^* and the hue angle are obtained. h, chroma C ^* ab. The measuring device may be a device in which an object can be placed in an analysis tube and the appearance color thereof can be measured. For example, a spectroscopic color difference meter SE2000 manufactured by Nippon Denshoku Industries Co., Ltd., or the like can be used.

Further, in the impression control agent of the present invention, the hue angle h(0) measured by the incident light angle of 45° and the light receiving angle of 0° is 40°<h(0)<100° by the measurement method 1 as described above. In other words, in the case where the diffused reflected light is a skin color and the surface reflected light is also a skin color, a gorgeous impression or a sexy impression can be exhibited.

On the other hand, in the chromaticity (a ^* , b ^* ) measured by the measurement method 1 at an incident light angle of 45°, a light receiving angle of -60°, 0°, and 45°, the light receiving angle is -60° to 0. The angle of change of ° is a ^* b ^{* The} direction of chromaticity change in the space, and the difference in chromaticity change direction in the a ^* b ^* space with the angle of change of -60° to 45° with the received light angle is 10° or more. In other words, when the hue changes depending on the angle of view, for example, when the diffused reflected light is a skin color and the surface reflected light is red, a cute impression or a feminine impression can be expressed; and the diffused reflected light is a skin color and the surface reflected light is In the case of green, it can show a mature impression and a dreamy impression. When the diffuse reflected light is the skin color and the surface reflection light is blue, it can show a calm impression and a sense of the city.

The above-mentioned examples of the expressions of each impression are designed to absorb the reflected light and the surface reflected light in a way that becomes the optical characteristic of each impression, and are applied to the entire face of the model, and the makeup face is specialized. The reviewer observes and grasps the person with the perceived impression.

More specifically, each chromaticity (a ^* (-60), b ^* (-60)) measured by the measurement method 1 at an incident light angle of 45°, an acceptance angle of -60°, 0°, and 45°, (a ^* (0), b ^* (0)) and (a ^* (45), b ^* (45)), the relationship between h' (45) and h' (0) obtained by Equations 1 and 2 In the case of |h'(45)-h'(0)|>10, various impressions can be exhibited.

(Formula 1) h'(0)=tan ^{- 1} ((b ^* (0)-b ^* (-60))/(a ^* (0)-a ^* (-60))) (Formula 2)h' (45)=tan ^{- 1} ((b ^* (45)-b ^* (-60))/(a ^* (45)-a ^* (-60)))

As described above, the impression control agent of the present invention can obtain a bright finish feeling in which the applied color (diffuse reflection component) is a skin color and has a transparent feeling, and the color of the surface reflected light is changed, whereby an impression unique to the color can be expressed. .

The impression control agent of the present invention can be produced by using, for example, the following components (A), (B) and (C): (A) a yellow iron oxide-coated pearl pigment having an average particle diameter of 5 to 15 μm; B) Red iron oxide coated pearl pigment with an average particle diameter of 5 to 15 μm; (C) a pearl pigment having an average particle diameter of 20 to 50 μm.
