Examples 1 to 5 and Comparative Examples 1 to 3 The transparent rod-type ultraviolet barrier composition prepared according to the composition and content of Table 1 and the opaque rod-type ultraviolet barrier composition prepared according to the composition and content of Table 2 Prepared according to the weight ratio in Table 3. Specifically, a mold is inserted into a rod-shaped container, and the rod-shaped container is filled with a transparent rod-type ultraviolet blocker composition (content 1) and cooled. After cooling, the mold was removed, and then the container was filled with an opaque rod-type ultraviolet blocker composition (content 2), and cooled to prepare Examples 1 to 5 and Comparative Example 1 to Comparative Example 3. A schematic diagram of a specific preparation method is shown in FIG. However, in Comparative Example 3, the container was filled using a composition without using a mold in which all the components in Tables 1 and 2 were mixed as contents. 【table 3】

The formulation in Example 3 prepared by the preparation method is shown in Fig. 1 below.

Experimental Example 1 (coated, non-white fog phenomena, concealer sense (Matteness), and comfort (fuzziness) Comparative) The production of the above-described Example 1 to Example 5 and Comparative Example 1 to Comparative Example 3 for 50 Normal People (aged from teens to 50 years old) were then assessed for a questionnaire, no white fog, concealing, and comfort. Scores range from 0 to 5, and if the corresponding item feels stronger, give a higher score. After the questionnaire evaluation, the results shown in Table 4 below were obtained. 【Table 4】

As in the questionnaire evaluation in Table 4, Examples 1 to 5 of the present disclosure obtained excellent scores in terms of coatability, no haze phenomenon, concealing feeling, and comfort.

Experimental Example 2 (Compasure of Coating Property) Comparative Example 1 and Example 3 were each applied to the forearm once, and then photographed under ultraviolet light (15 watt ultraviolet lamp manufactured by Sankyo Ultraviolet Co., Ltd.) (iPhone made by Apple) 6 rear camera) to compare the applicability of each sample. Part of the absorbed light having the ultraviolet blocking component appears black, and the portion without the ultraviolet blocking component appears blue. When the black portion is large and deep, the line sample can be considered to be well coated.

The experimental results are shown in Figure 2. In Fig. 2, the example 3 is on the left and the example 1 is compared on the right. In Fig. 2, the left side is marked with a darker color, and the right side is marked with a lighter color. Therefore, as shown in FIG. 2, it was confirmed that the left example 3 exhibited better coatability than the right comparative example 1.

Experimental Example 3 (viscosity comparison) Comparative Example 2 and Example 3 were applied once to the back of the hand, and when the back of the hand was pressed against the coffee grounds and taken out therefrom, the amount of coffee grounds to which each sample adhered to the back of the hand was visually compared. .
