Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an oil-based cosmetic, which provides a smooth feeling of use at the time of application, furthermore does not cause perspiration, and is excellent in stability over time and fillability. Is what you do.

[0002]

2. Description of the Related Art Conventionally, studies have been made to produce various organoleptic effects by changing the blending amounts of solid oil, semi-solid oil and liquid oil. In particular, when producing a smooth feeling during application, a smooth feeling of use can be generally obtained by blending a large amount of semi-solid oil and liquid oil. However, since the amount of liquid oil is increased relative to the amount of solid oil in the entire system, the liquid oil held by the solid oil is spit out under high-temperature conditions, causing perspiration and reducing the stability over time. There were drawbacks. Also, instead of changing the amount of the oil agent, various powders such as spherical powders and plate-like powders were blended to give a sliding feeling and to produce a smooth feeling of use. However, even if the powder is mixed at a high temperature at the time of filling, the viscosity is so high that the filling moldability is lowered, a hard feel is obtained, and the adhesion is unfavorably lowered.

[0003]

In the above-mentioned conventional products, while a smooth feeling of use is obtained, the stability over time due to perspiration and the like, and the adhesion to the skin and the filling moldability due to a change in the viscosity of the system are reduced. Was invited.

[0004]

Under these circumstances, the present inventors have conducted intensive studies to solve the above-mentioned problems. As a result, the oil-based cosmetic contains silica of a specific shape and triglyceride solid at room temperature. As a result, the present inventors have found that a cosmetic having a smooth feeling in use and excellent in stability over time can be obtained, and have completed the present invention. That is, the present invention provides a composition (A) having an average particle size of 15 to 50 μm and a thickness of 1.5 μm.
The present invention provides an oily cosmetic which exhibits a smooth feeling upon application by containing flaky silica of m or less and component (B) triglyceride which is solid at room temperature, and has excellent stability over time.
