Description

The present invention relates to an oil-in-water make-up cosmetic. According to the underwater oil type make-up cosmetic of the present invention, it is possible to provide an underwater oil type make-up cosmetic having excellent stability, high skin safety, good usability, and long-lasting makeup. ..

Makeup cosmetics are cosmetics for making the skin color and texture look beautiful, and typical makeup cosmetics include foundations, eye colors, and eyeliners. These make-up cosmetics include oil-in-water (O / W) preparations and water-in-oil (W / O) preparations.

Since the oil-in-water formulation contains more water than the water-in-oil formulation, it is less sticky due to oil and is easier to remove, but the cosmetic film formed by applying it to the skin is more compatible with sweat and water and has makeup lasting. Had the drawback of being bad. Further, there remains a problem regarding storage stability, such as separation into an oil phase and an aqueous phase due to storage.

Patent Document 1 discloses a water-resistant and oil-resistant underwater make-up cosmetic containing a water-dispersible silicone resin and a fluorine-based resin. Further, Patent Document 2 discloses an oil-in-water make-up cosmetic having a long-lasting makeup by blending gellan gum, phospholipid, cholesterol and / or phytosterol, and a plate-like powder. However, when a fluororesin or a plate-like powder is blended, there is a drawback that the powder becomes powdery and the usability deteriorates. Therefore, there has been a demand for an oil-in-water make-up cosmetic having desired storage stability and long-lasting makeup while maintaining a good feeling of use.
