DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a makeup cosmetic which has good persistence of makeup, has a smooth and excellent feel upon application, and has good stability over time.

[0002]

2. Description of the Related Art Makeup cosmetics are usually composed of pigments and oils as main components, and the continuity of makeup as performance is extremely important. Conventionally, aqueous components such as sweat and water have attracted attention as a cause of makeup loss, and pigments whose surfaces have been treated with metal soaps, fatty acids, phospholipids, silicone oils, etc. have been used to prevent such makeup loss. . However, makeup cosmetics containing these surface-treated pigments have water repellency but no oil repellency, so that it was not possible to prevent cosmetics from being damaged by oily components such as sebum. From such a viewpoint, a pigment having a surface coated with a fluoroalkyl phosphate amine salt has been developed as a pigment having both water repellency and oil repellency (JP-A No.
No. 62-250074).

[0003]

However, it has been found that various drawbacks occur when a makeup cosmetic is prepared by simply blending the above-mentioned water- and oil-repellent pigment with a usual oil agent. That is, a water-repellent / oil-repellent color pigment has poor wettability with a normal oil agent, and therefore, when used as a cosmetic, the dispersibility of the pigment is deteriorated; The oil has a poor affinity for the pigment and the pigment, so that the hardness value is lowered and the impact resistance against falling etc. is lowered. In the case of an oily product, the product has poor wettability with a normal oil as a dispersion medium. In addition, sweating and floating or aggregation of the pigment may occur. Accordingly, there has been a demand for a makeup cosmetic which has excellent cosmetic persistence for an aqueous component and an oily component, has a good feeling in use, and has good stability over time of a product.

[0004]

Under such circumstances, the present inventors have conducted intensive studies and as a result, have found that the surface of a water-repellent / oil-repellent pigment whose surface is coated with a fluoroalkyl phosphoric acid ester amine salt, and a cosmetic oil agent It has been found that a makeup cosmetic having excellent makeup continuity, good feel, and excellent stability over time can be obtained by using the double-coated pigment coated with, and the present invention has been completed.

That is, the present invention provides the following general formula (1)

Embedded image (Wherein, n represents an integer of 6 to 18) and a compound represented by the general formula (2):

For the double-coated pigment used in the present invention, for example, a cosmetic oil is dissolved or dispersed in a volatile solvent, the above-mentioned water- and oil-repellent pigment is mixed with the oil, and then the solvent is distilled off under reduced pressure. It is manufactured by removing and optionally grinding. The coating amount of the cosmetic oil agent on the water- and oil-repellent pigment is preferably 1 to 10% by weight (hereinafter simply referred to as%) based on the water- and oil-repellent pigment. If it is less than 1%, a sufficient covering effect cannot be obtained, and if it exceeds 10%, there is no difference in the effect and it is not efficient.
