(Example)

In the following example, for components other than liquid caustic potash, the raw materials are formulated in such a way that the content of each component in the obtained composition is as described in Table 1 to Table 4 according to the amount of the component contained in the raw material , And obtain the composition. In addition, in Tables 1 to 4, for liquid caustic potassium, the blending amount is shown with a composition of 48% KOH.

(Examples 1 to 28 and Comparative Examples 1 to 6)

Use the following method to manufacture the oil-in-water UV protection cosmetics (sunscreen cosmetics) with the composition shown in Tables 1 to 4, and use the following methods to treat the stickiness under high temperature environment (30℃, 45%RH) Evaluate the elimination of sex, the continuation of moisturizing, the smoothness of the skin after 30 minutes of application, and the whiteness of the appearance when applied to black leather. The results are shown in Table 1 to Table 4. In addition, for some examples, the dynamic stability of the obtained cosmetics was also evaluated. The results are shown in Table 4.

(How to make cosmetics)

The component (D) was added while stirring the component (B) at 25°C. While stirring, it is added to a mixing tank containing water to prepare a water phase. On the other hand, the component (A) and the component (E) are heated and stirred at 80°C, and then the component (C) and the component (F) are added to prepare an oil phase. After that, while stirring and heating the obtained water phase to 80°C, adding the above-mentioned oil phase and alkali and other ingredients, and stirring while cooling to room temperature (25°C), the oil in water described in each table was obtained. Sunscreen cosmetics.

(Evaluation method) (Removal of stickiness under high temperature environment)

A professional sensory inspector smeared 0.02mL of cosmetics on the inside of the forearm into a circle with a diameter of 3cm. After applying the cosmetics, after 20 minutes at 30°C and 45% RH, sensory evaluation was performed by touching the application part with a finger. The standard was divided into 4 stages, and the case where it was judged that no stickiness was felt at all was evaluated as 4, and the case where it was judged to be very sticky and could not be used in practice was evaluated as 1.

(Continuation of moisturizing)

^{A professional sensory inspector measured the TEWL (g/cm 2} ) on the inner forearm using a percutaneous moisture loss tester Tewameter TM300 (manufactured by Courage+Khazaka electric GmbH). After the measurement, apply approximately 0.02 mL of cosmetic material to a circle with a diameter of 3 cm at the same position, and after applying it for 30 minutes, measure TEWL (g/cm ² ) at 25° C. and 57% RH. The TEWL (g/cm ² ) before the cosmetic application is set to TEWL1, and the TEWL (g/cm ² ) after the cosmetic application is set to TEWL2, and the moisturizing properties are obtained by the following formula. The higher the value, the better the durability of moisturizing.

Moisturizing △TEWL=TEWL1-TEWL2

(Smoothness of the skin after 30 minutes of application)

A professional sensory inspector smeared 0.02mL of cosmetics on the inside of the forearm into a circle with a diameter of 3cm. After applying the cosmetics, after 30 minutes at 25°C and 57% RH, sensory evaluation was performed by touching the application part with a finger. The standard was divided into 4 stages, and cases judged to be very smooth were evaluated as 4, and cases where no smoothness was felt at all but actually unusable were evaluated as 1.

(The degree of whitening when applied to black leather)

Put the cosmetic on the black artificial leather made of urethane and apply it to a thickness of 0.02mm with an applicator. After application, a professional sensor inspector will conduct a visual evaluation. The standard was divided into 4 stages, and the case where it was judged that the degree of whitening of the appearance was not felt at all was evaluated as 4, and the case where it was judged that the degree of whitening of the appearance was judged to be very high and it was actually unusable was evaluated as 1.

(Evaluation of dynamic stability)

Put 20mL of cosmetics into a 50mL cylindrical plastic container. The container was attached to a rotating machine and rotated at 10 rpm. After rotating for 3 hours, a professional inspector visually judges the appearance and properties of the cosmetics. The standard was divided into 4 stages, and cases where there was no change in appearance and properties were evaluated as 4, and cases where it was judged that the appearance and properties had deteriorated and could not be actually used as a product were evaluated as 1.
