Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an oil-in-water emulsified cosmetic for concealing pores containing a whisker-like powder, a plate-like powder and an adhesive substance. The present invention relates to an oil-in-water emulsified cosmetic for concealing pores that has a long-lasting effect and has no feeling of burden on the skin.

[0002]

2. Description of the Related Art In recent years, foundations that are more transparent than the cover effect of concealing the skin have been well received in the market. In the case of using such a foundation having a high transparency, it is necessary to previously deal with skin defects such as dullness, pores, wrinkles, and the like by using a base material, a control material, and the like. Dullness,
Among the skin defects such as pores and wrinkles, the pores are particularly troublesome for women of all ages. For this reason, many cosmetics for concealing pores have been put on the market in order to respond to the concerns of these consumers. In those conventional cosmetics for concealing pores,
The pore concealing technique shown below was used. Technology for filling pores with solid oil, film-forming polymer, etc. Technology for covering pores themselves with highly opaque powders such as titanium oxide and zinc oxide Optics utilizing the light scattering effect of spherical powders such as silicic anhydride Technology that makes pores less noticeable

[0003]

However, the conventional pore concealing techniques as described above have the following disadvantages. According to the technology, solid oil and a film-forming polymer remain clogged in pores, causing a feeling of burden on the skin. In addition, when the cosmetic is dropped (cleansing), the clogged cosmetics are completely removed. It was not easy to remove. According to the technique described above, the pores themselves can be concealed, but the cosmetic film itself formed on the skin becomes thick, resulting in an unnatural finished feeling and a feeling of burden on the skin in some cases. According to the technique described above, a certain degree of pore concealing effect can be obtained immediately after makeup, but due to the shape characteristics of the spherical powder, the spherical powder tends to gather around the pores over time to make the pores more noticeable. For this reason, there has been a demand for the development of a cosmetic for concealing pores which is excellent in pore concealing effect with a natural finish feeling and which maintains the effect for a long time and has no feeling of burden on the skin.

[0004]

Under such circumstances, the present inventors have conducted intensive studies, and as a result, have found that whisker-like powder having an excellent light scattering effect is excellent in concealing pores. An oil-in-water emulsified cosmetic for concealing pores, which uses an adhesive substance in combination to fix the substance around the pores, solves the above-mentioned problems, and has completed the present invention.

That is, the present invention provides the following components (a) to
(C); (a) Whisker-like powder (b) Plate-like powder (c) An oil-in-water emulsified cosmetic for concealing pores, comprising (c) an adhesive substance.

Cosmetics, component (a), minor axis 0.6-2.0 μm, major axis 5-40 μm
Wherein the oil-in-water emulsified cosmetic for concealing pores is provided. Furthermore,
Any of the above pores, which contains the component (a) in an amount of 0.1 to 5% by mass and the component (b) in an amount of 5 to 30% by mass based on the total mass of the oil-in-water emulsion cosmetic for concealing pores. It is intended to provide an oil-in-water emulsified cosmetic for covert use.
