EXAMPLES Hereinafter, although an Example and a comparative example demonstrate this invention further more concretely, this invention is not limited only to these Examples.
In addition, evaluation of the liquid foundation of an Example and a comparative example was implemented with the following method.

(Separated state)
The separation state after 30 days at 50 ° C. was confirmed by visual observation, the change in state was confirmed by feeling of use (tactile sensation, viscosity), and evaluated according to the following criteria.
(Double-circle): Separation of a powder and an oil-based component is not recognized, and the change of a state is not recognized.
○: Separation of powder and oil component is not observed, but a slight change is observed in the state.
X: Separation of powder and oil component is recognized.
(Feeling of use)
Usability was evaluated by 10 female panelists. The average score of 10 people was evaluated as an evaluation result, with 5 levels of answers ranging from poor usability (0 points) to good usability (5 points).
(Water repellency)
The liquid foundation was applied on a glass plate, and after drying, water was dropped to measure the contact angle.

[Production Example 1]
3 g (0.05 mol) of ethylenediamine was mixed with 57 g of water. While adjusting the pH of this solution to 10 to 11 with a 25% aqueous sodium hydroxide solution and maintaining the reaction temperature at 5 ° C., 39.5 g (0.1 mol) of N-stearoyl glutamic anhydride was added with stirring. The reaction was carried out after 2 hours. After stirring for another 30 minutes, tertiary butanol was added to a concentration of 20% by weight in the liquid, 75% sulfuric acid was added dropwise to bring the pH value of the liquid to 2, and the liquid temperature to 65 ° C. It was adjusted. After completion of the dropwise addition, stirring was stopped and the mixture was allowed to stand at 65 ° C. for 20 minutes, so that the organic layer and the aqueous layer were separated, and the organic layer was separated therefrom. Tertiary butanol and water were added to the separated organic layer, the temperature was raised to 65 ° C., and the mixture was stirred for 20 minutes. After the stirring was stopped, the mixture was allowed to stand to separate into an organic layer and an aqueous layer. After repeating the same water washing operation with respect to the obtained organic layer, the solvent was removed from the obtained organic layer and dried to obtain a white solid. The acid value of this white solid was 224.

[Examples 1-5, Comparative Examples 1-2]
A liquid foundation was produced by the composition and production method shown in Table 1, and evaluated by the above method. The results are shown in Table 1. Since Examples 1-5 satisfy the requirements of the present invention, it can be seen that they are excellent in stability, usability and water repellency.

[Example 6, Comparative Example 3]
(C) component of Table 2 was mixed and the oil phase in which the powder was disperse | distributed was manufactured. (D) component of Table 2 was mixed beforehand, the said oil phase was disperse | distributed there with a homomixer, the liquid foundation was manufactured, and it evaluated by the said method. The results are shown in Table 2. Since Example 6 satisfies the requirements of the present invention, it can be seen that the stability, usability, and water repellency are excellent.

  According to the present invention, it is possible to provide a powder-dispersed water-based cosmetic having excellent stability and good usability and excellent water repellency after application.
