Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a foundation, and more particularly, to a foundation capable of concealing pores and preventing dullness of the skin without losing a feeling of bare skin or transparency.

[0002]

2. Description of the Related Art The conventional foundation employs a finishing method in which a color close to one's own skin color is applied on the skin to hide spots, freckles, uneven color, and acne marks. It had been. However, such a foundation relies solely on the covering power, so that both the color of the cheeks and the color of the forehead will be covered with the same color, the redness of the cheeks on the original human skin and the transparent white All skin features are lost. For this reason, there has recently been a strong demand for a feeling of bare skin and a sense of transparency rather than covering power, and there has been a strong demand for a foundation with a feeling of bare skin that can hide only ara while utilizing one's bare skin.

[0003] Accordingly, the object of the present invention is not to lose the bare skin feeling and transparency even when used in the same manner as a normal foundation,
It is an object of the present invention to provide a foundation in which only defects such as pores and dullness are hidden while using bare skin.

[0004]

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, by using a specific powder composition having specific properties, a foundation having a sense of bare skin different from the conventional one has been obtained. I found something to be done.

That is, the present invention relates to titanium oxides of 0 to 5.0.
A foundation comprising 0 to 10.0% by weight of fine particle titanium oxide, 0 to 0.5% by weight of pigment powder, and 7.0 to 90.0% by weight of spherical powder other than titanium oxides and pigments. 0.3 g of the foundation on the arm
/ A 25 cm ^2, and the spectral reflectance when colorimetrically measured is (A), and the spectral reflectance when colorimetrically measured without applying a foundation is (B), wavelength 400-700 mm
Is a foundation characterized by (A)-(B)> 0.

[0006] The "foundation" in the present invention is:
It is usually applied with a sponge or finger after applying lotion or milky lotion, or after applying a makeup base, concealing skin spots, freckles, uneven color, etc., and changing the skin color to the desired color evenly What is used for the purpose of effect.

The titanium oxide used in the present invention includes:
It may be one generally used for cosmetics, and an untreated product or a hydrophobized product can be used depending on the dosage form. The amount of titanium oxide is 0 to 5.0% by weight, preferably 0 to 5.0% by weight.
~ 3.0% by weight. If the amount of titanium oxide exceeds 5.0% by weight, the bare skin feeling and the transparency are lost.

The fine particle titanium oxide used in the present invention has a plate-like particle shape and a size of 0.01 to 0.10.
μm and a thickness of 0.003 to 0.03 μm, the particle shape is nearly spherical, and the average particle size is 0.01 to 0.10 μm
m, the particle shape is spindle-shaped, and the minor axis is 0.005.
0.02 μm and a major axis of 0.01 to 0.10 μm. An untreated product or a hydrophobized product can be used as the fine particle titanium oxide depending on the dosage form.
The compounding amount of the fine particle titanium oxide is 0 to 10.0% by weight, preferably 0 to 8.0% by weight. If the amount of titanium oxide exceeds 10.0% by weight, the feeling of bare skin and the feeling of transparency are lost.

The spherical powder used in the present invention includes spherical silica, spherical nylon powder, spherical alkyl polyacrylate, crosslinked polystyrene-squalane mixed powder, cellulose powder, silicic anhydride powder and methylsiloxane network polymer powder. Can be These spherical powders may be untreated or hydrophobically treated depending on the dosage form. The amount of the spherical powder varies depending on the dosage form. For example, 7.0 to 20.0% by weight in an oil-in-water emulsion foundation, and 7.0 to 50 in an oily foundation, a water-in-oil emulsion foundation, and a solid emulsion foundation. .0
% By weight, 7.0 to 90.% in solid powder foundation.
0% by weight. If the amount of titanium oxide is less than 7.0% by weight, the effect of hiding pores on the skin and adjusting texture becomes insufficient.

In the foundation of the present invention, the foundation is applied to the arm at a rate of 0.3 g / 25 as a spectral reflectance characteristic.
Assuming that the spectral reflectance when colorimetrically measured by applying cm ² is (A) and the spectral reflectance when colorimetrically measured without applying a foundation is (B), (A) − is always obtained at a wavelength of 400 to 700 mm. (B) is characterized in that> 0. By using a foundation having this property, a transparent feeling or a bare skin feeling can be imparted when applied to the skin.
