In the following examples, for the components other than liquid caustic potash, each component is contained in the obtained composition according to the amount of the component contained in the raw material so that the content of each component is as shown in Tables 1 to 4. The raw materials were blended to obtain a composition. Further, in Tables 1 to 4, the amount of liquid caustic potash to be blended in the composition as 48% KOH is shown.

(Examples 1-28 and Comparative Examples 1-6)
The oil-in-water UV protection cosmetics (sunscreen cosmetics) having the compositions shown in Tables 1 to 4 are produced by the method described later, and are sticky in a high temperature environment (30 ° C., under 45% RH) by the method described later. The lack of moisture, the duration of moisturizing, the smoothness of the skin 30 minutes after application, and the whiteness of appearance when black leather was applied were evaluated. The results are also shown in Tables 1 to 4.
The dynamic stability of the obtained cosmetics was also evaluated in some cases. The results are shown in Table 4.

(Manufacturing method of cosmetics)
At 25 ° C., the component (D) was added while stirring the component (B). This was added to a compounding tank containing water with stirring to prepare an aqueous phase. On the other hand, the component (A) and the component (E) were heated and stirred at 80 ° C., and further, the component (C) and the component (F) were added to prepare an oil phase. Then, the obtained aqueous phase is heated and stirred at 80 ° C., the oil phase and other components such as a base are added, and the mixture is cooled to room temperature (25 ° C.) while stirring, and the oil in water shown in each table is used. I got a sunscreen cosmetic.

(Evaluation method)
(Non-stickiness in high temperature environment)
One expert panelist applied 0.02 mL of cosmetic to the inside of the forearm in a circle with a diameter of 3 cm. After 20 minutes had passed at 30 ° C. and 45% RH after applying the cosmetic, sensory evaluation was performed by touching the applied portion with a finger. The criteria were divided into 4 stages, and the case where it was judged that the stickiness was not felt at all was evaluated as 4, and the case where the stickiness was felt very much and it was judged that the actual use was not possible was evaluated as 1.

(Continued moisturizing)
TEWL (g / cm ² ) on the inside of the forearm was measured by one expert panelist with the Tewameter TM300 (Courage + Khazaka electric GmbH). After the measurement, about 0.02 mL of cosmetic was applied to the same place in a circle having a diameter of 3 cm, and 30 minutes after the application, TEWL (g / cm ² ) was measured at 25 ° C. and 57% RH. The TEWL (g / cm ² ) before application of cosmetics was TEWL1 and the TEWL (g / cm ² ) before application of cosmetics was TEWL2, and the moisturizing property was determined by the following formula.
Moisturizing ΔTEWL = TEWL1-TEWL2
The higher the number, the better the moisturizing sustainability.

(Skin smoothness 30 minutes after application)
One expert panelist applied 0.02 mL of cosmetic to the inside of the forearm in a circle with a diameter of 3 cm. After applying the cosmetics, 30 minutes passed at 25 ° C. and 57% RH, and then the sensory evaluation was performed by touching the applied portion with a finger. The criteria were divided into 4 stages, and the case where it was judged that the smoothness was very felt was evaluated as 4, and the case where the smoothness was not felt at all and it was judged that the actual use was not possible was evaluated as 1.

(Whiteness of appearance when black leather is applied)
Cosmetics were placed on urethane black artificial leather and applied to a thickness of 0.02 mm with an applicator. After application, one expert panelist performed a visual evaluation. The criteria were divided into 4 stages, and the case where it was judged that the whiteness of appearance was not felt at all was evaluated as 4, and the case where the whiteness of appearance was felt very much and it was judged that the actual use was not possible was evaluated as 1.

(Evaluation of dynamic stability)
20 mL of cosmetics was placed in a 50 mL columnar plastic container. This was attached to a rotating machine and rotated at 10 rpm. After 3 hours of rotation, one specialist panelist visually judged the appearance and properties of the cosmetics. The criteria were divided into four stages, and the case where there was no change in appearance / properties was evaluated as 4, and the case where the appearance / properties deteriorated and it was judged that the product could not be actually used was evaluated as 1.
