DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an emulsifying type and a dispersing type cosmetic, and more particularly, it has a high refreshing sensation, is excellent in elongation, spreadability and non-adhesiveness on the skin, and has a uniform and beautiful skin feeling. The present invention relates to an emulsion-type and dispersion-type cosmetic which is obtained, has high adhesion to the skin, and has excellent cosmetic durability.

[0002]

2. Description of the Related Art Cosmetics, especially make-up cosmetics, are used for the purpose of creating beautiful skin, and in the market, performance such as elongation, spreadability, non-adhesiveness, etc. on the skin is required to achieve the purpose. There is a demand for a feel to the skin such as a refreshing sensation, and further, a performance of making pores, fine wrinkles and the like inconspicuous. In order to achieve such performance, conventionally, porous silica, a method using a functional powder such as a composite powder obtained by treating a plate-like powder with a fine metal oxide, a cosmetic is adhered to the skin like a mesh, A method of preventing powder in cosmetics from dropping into pores is used. However, these methods provide high effects in powder cosmetics and high-viscosity solid cosmetics, but in emulsifying and dispersing cosmetics, emulsification or dispersion is difficult when a large amount of powder is blended. As a result, a sufficient amount of functional powder cannot be blended, and because of its poor adhesion to the skin, if it is attempted to adhere to the skin in a mesh-like manner, the powder concentrates in the skin groove and the powder in the skin hills However, there is a problem that it is difficult to adhere.

[0003] Methods for solving the above-mentioned problems in emulsifying and dispersing cosmetics include (1) changing the shape of the contained functional powder, miniaturizing the particle size, and (2) dissolving water such as collagen and chitosan. Of surface treatment agents or surface treatment methods, such as using a conductive polysaccharide as a surface treatment agent for powders
No. 20090111), and (3) a method of blending a high-viscosity oil, a surfactant, a high-melting polymer, a thickener, an adhesive and the like (Japanese Patent Application Laid-Open No. 5-58840).
However, in the method (1), not only the performance of the functional powder is reduced, but also the viscosity of the system is increased, and the spreadability is impaired. In the method (2), the treating agent is hydrophilic. Therefore, there is a problem that the water resistance after application is reduced, and the durability of the makeup is deteriorated. In addition, although the method (3) improves the adhesion to the skin, it has an oily feeling, stickiness, and peelability. In addition, there is a problem that a feeling of use such as repellency deteriorates.

[0004]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide not only a high refreshing feeling, excellent elongation, spreadability and non-adhesiveness on the skin, but also a uniform and beautiful bare skin feeling.
