BACKGROUND OF THE INVENTION
The present invention relates to an additive color mixing agent that can naturally change the hue of skin without dulling the skin.
[0002]
[Prior art]
Conventionally, make-up cosmetics cover skin dullness due to poor circulation or aging (skin is dark and yellowish), so pigments with high hiding power such as titanium oxide, zinc white, aluminum and iron oxide are used. Mixing or adding red, such as Bengala, lake pigments and organic pigments, to change the hue of the skin.
[0003]
On the other hand, to hide the red face and red acne scars, it is possible to change the skin hue sensation by using a green pigment that is a complementary color of red, or by using a blue or purple pigment to give a sense of transparency. Has been done.
[0004]
However, when a pigment with high hiding power is used, there is a problem in that there is no transparency and the result is an unnatural finish. In addition, when the principle of complementary colors is used, there is a problem that although the hue can be covered, the saturation is lowered and the skin color is dull. These problems occur because the method is a hue control based on subtractive color mixture, and is caused by the fact that if the colors are overlapped, the saturation is lowered and the color approaches gray.
Thus, with conventional makeup cosmetics, it has been difficult to change the hue sensation of the skin while providing a sense of transparency.
[0005]
[Problems to be solved by the invention]
Accordingly, an object of the present invention is to provide an additive color mixing agent that can naturally change the hue of the skin without dulling the skin.
[0006]
[Means for Solving the Problems]
In such a situation, the present inventors have conducted intensive research. As a result, the principle of additive color mixing, that is, color mixing using light, is used instead of the conventional subtractive color mixing principle. When two or more kinds of powders having specific properties are mixed and used, an additive color mixing agent capable of naturally changing the skin hue feeling without dulling the skin by the reflected light from the powder is obtained. The headline and the present invention were completed.
[0007]
In other words, the present invention Of a mixture of titanium oxide and iron oxide A powder coated with particles, which is 8 mg / 100 cm on black synthetic leather ² A variable angle spectrophotometer with a polarizing filter attached so that the reflected light having a vibration surface in the same direction as the vibration surface of the incident light is detected on the incident light side and the reflected light side. Measured at an incident angle of 45 ° and a light receiving angle of −45 °, the spectral reflectance (surface reflected light) curve at a wavelength of 400 to 700 nm has a maximum value or a minimum value, and the maximum value of the spectral reflectance of the maximum value. (If there is no maximum value, the maximum value at a wavelength of 400 to 700 nm) is 0.74 to 1.58 (Standard white board is 1) so And the maximum value (maximum value / minimum value) ratio between the maximum value and the minimum value (the ratio between the maximum value or the minimum value at a wavelength of 400 to 700 nm when there is no maximum value or minimum value). 2.19 to 4.33 A combination of two or more selected from powders that are: a powder having a maximum spectral reflectance at 400 to 500 nm (blue) and a powder having a minimum at 450 to 550 nm (blue) An additive colorant that is a combination of a powder having a spectral reflectance maximum value of 400 to 500 nm (blue system) and a powder having a minimum value of 400 to 500 nm (yellow system). It is to provide.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
The powder used in the present invention has a maximum or minimum spectral reflectance (surface reflected light) curve at a wavelength of 400 to 700 nm, and the maximum spectral reflectance when the standard white plate is 1. The value is 0.6 or more and the maximum value of the ratio between the maximum value and the minimum value (maximum value / minimum value) is 1.5 or more. When the maximum reflectance of the maximum value is less than 0.6 or the ratio of the maximum value to the minimum value (maximum value / minimum value) is less than 1.5, the effect is obtained when colors are mixed. It becomes weak and dull, and it is difficult to naturally change the skin hue sensation. Here, in order to obtain the spectral reflectance, first, the powder is applied to black synthetic leather at 8 mg / 100 cm. ² And apply evenly by gently rubbing the synthetic leather using a sponge. This is reflected by, for example, a variable angle spectrophotometer (GCMS-3, manufactured by Murakami Color Research Laboratory), with a polarizing filter having a vibration surface in the same direction as the vibration surface of the incident light on the incident light side and the reflected light side.
