(Example)

In the following examples, the components other than the liquid caustic potassium are formulated in such a manner that the content of each component in the obtained composition is as described in Tables 1 to 4, depending on the amount of the components contained in the raw material. And get the composition. Further, in Tables 1 to 4, the composition amount of the liquid caustic potash was 48% KOH.

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

The underwater oil type ultraviolet defense cosmetic (sunscreen cosmetic) having the composition shown in Tables 1 to 4 was produced by the following method, and was sticky to a high temperature environment (at 30 ° C, 45% RH) by the following method. The elimination of sex, the persistence of moisturization, the smoothness of the skin after 30 minutes of application, and the degree of whiteness of the appearance when applied to black leather were evaluated. The results are shown together in Tables 1 to 4. Also, for some examples, the dynamic stability of the obtained cosmetic was also evaluated. The results are shown in Table 4.

(Manufacturing method of cosmetics)

The component (D) was added while stirring the component (B) at 25 °C. The aqueous phase was prepared by adding it to the mixing tank containing water while stirring. On the other hand, the component (A) and the component (E) were heated and stirred at 80 ° C, and then the component (C) and the component (F) were added to prepare an oil phase. Thereafter, the obtained aqueous phase was stirred and heated to 80 ° C, and the other components such as the oil phase and the alkali were added thereto, and the mixture was cooled to room temperature (25 ° C) while stirring to obtain the oil in the water shown in each table. Sunscreen cosmetics.

(evaluation method) (elimination of stickiness in high temperature environment)

A professional functional inspector applied 0.02 mL of the cosmetic to the inside of the forearm to a circle having a diameter of 3 cm. After applying the cosmetic, after 20 minutes at 30 ° C and 45% RH, the sensory evaluation was performed by touching the application portion with a finger. The standard was divided into four stages, and the case where it was judged that the viscosity was not felt at all was evaluated as 4, and the case where it was judged to be very sticky and practically unusable was evaluated as 1.

(continuation of moisturizing)

The TEWL (g/cm ² ) inside the forearm was measured by a professional inspector using a transcutaneous moisture loss tester Tewameter TM300 (manufactured by Courage+Khazaka Electric GmbH). After the measurement, about 0.02 mL of the cosmetic was applied to a circle having a diameter of 3 cm at the same position, and after applying for 30 minutes, TEWL (g/cm ² ) was measured at 25 ° C and 57% RH. The TEWL (g/cm ² ) before the application of the cosmetic was set to TEWL1, and the TEWL (g/cm ² ) after the application of the cosmetic was set to TEWL2, and the moisture retention property was determined by the following formula. The higher the value, the more excellent the persistence of moisturizing.

Moisture retention △TEWL=TEWL1-TEWL2

(Smoothness of the skin after 30 minutes of application)

A professional functional inspector applied 0.02 mL of the cosmetic to the inside of the forearm to a circle having a diameter of 3 cm. After applying the cosmetic, after 30 minutes at 25 ° C and 57% RH, the sensory evaluation was performed by touching the application portion with a finger. The standard was divided into four stages, and the case where it was judged to be very smooth was evaluated as 4, and the case where the smoothness was not felt at all and the actual use was not evaluated was evaluated as 1.

(The degree of whitening of the appearance when applied to black leather)

The cosmetic was placed on a black artificial leather made of urethane and applied to a thickness of 0.02 mm by an applicator. After application, visual evaluation was performed by a professional inspector. The standard was divided into four stages, and the case where it was judged that the blushing degree of the appearance was not felt at all was evaluated as 4, and the case where the blushing degree of the perceived appearance was very high and the actual unavailability was not evaluated was evaluated as 1.

(Evaluation of dynamic stability)

20 mL of the cosmetic was placed in a 50 mL cylindrical plastic container. The container was mounted on a rotary machine and rotated at 10 rpm. After rotating for 3 hours, the appearance and properties of the cosmetic were visually judged by a professional inspector. The standard was divided into four stages, and the case where the appearance and the trait were not changed was evaluated as 4, and it was judged as 1 when the appearance and the trait were deteriorated and the product was not actually used as a product.
