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, and more particularly, to an oil-based cosmetic which has a non-sticky feeling of use, a fit, and a long lasting makeup.

[0002]

2. Description of the Related Art Conventionally, oily cosmetics such as foundations, lipsticks, eye shadows, eyeliners, and the like have stickiness when used, and have poor makeup lasting when applied to the skin. There were drawbacks.
Attempts have been made to mix low-viscosity oils, especially silicone-based oils, to reduce stickiness.However, although silicone-based oils alone do not provide stickiness, poor adhesion to the skin and poor fit, Make you last longer. Attempts have also been made to improve the fit and long-lasting by adding a film-forming agent such as a polymer, but there is a drawback that the feeling of the film remains after the film is formed and the usability is impaired. Accordingly, an object of the present invention is to provide an oil-based cosmetic which has the above-mentioned disadvantages and is free from stickiness, has a feeling of fit, and has excellent cosmetic durability.

[0003]

Means for Solving the Problems In view of such circumstances, the present inventors have conducted intensive studies and as a result, have found that specific polysiloxane-
The present invention has been found that by combining a polyoxyalkylene copolymer with another silicone derivative, an oily cosmetic having characteristics of smooth use, fit, and excellent durability can be obtained. Was completed.
