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 which contains a fluorine compound-treated powder stably, has excellent sebum resistance and water resistance, and has a good feeling in use.

[0002]

2. Description of the Related Art It is known that powders treated with a fluorine compound can be used in cosmetics as powders having excellent water resistance, sweat resistance and sebum resistance. However, the fluorine compound-treated powder has a problem in that it has poor affinity with other additives usually used in cosmetics, and it is difficult to obtain a stable cosmetic when blended. In particular, there has not yet been found an example in which a fluorine compound-treated powder is stably blended with an oil-in-water emulsion type cosmetic.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to make it possible to stably blend a powder treated with a fluorine compound while being an oil-in-water emulsified cosmetic. An object of the present invention is to provide an oil-in-water emulsified cosmetic which is excellent in water resistance, sweat resistance and sebum resistance and has good makeup durability while maintaining the above-mentioned good elongation and freshness.

[0004]

As a result of repeated studies to solve the above problems, one or more selected from propylene glycol and its derivatives, and one or more selected from fluorine compound-treated powders By containing two or more, one or more selected from fluorine-based oils, and water, the desired oil-in-water emulsion cosmetic could be obtained. More specifically, by dispersing a fluorine compound-treated powder and a fluorine-based oil component in water using propylene glycol and a derivative thereof, an oil-in-water emulsified cosmetic having good emulsification stability and excellent durability can be obtained. I was able to.
