Examples and experimental examples of the present invention are provided to more completely describe the present invention to those of ordinary skill in the art.

Manufacturing example One. Example 1 and Comparative example Preparation of 1 to 4

A lipstick was prepared in the composition shown in Table 1 below.

The manufacturing method is as follows.

1. First, the wax and oil of Table 1 were weighed in a beaker according to their content (% by weight) and dissolved by heating at 85 to 90° C., and then uniformly mixed for 15 minutes at 2500 rpm using a Homogenizer.

2. Thereafter, all other pigments including black iron oxide were added at the same temperature (85 ~ 90 ℃), and uniformly mixed for 5 minutes at 2500 rpm.

3. The composition mixed in the above 2 was subjected to a process of degassing and flavoring, molded in a magnetic mold, and cooled to prepare a lipstick.

The magnetic mold used in the present embodiment has a plurality of magnets arranged in layers in the mold so that black iron oxide, which is a magnetic particle, is oriented in multiple layers, and is manufactured so as to exhibit the pattern as in FIGS. 1 to 4. It goes without saying that various patterns can be formed by controlling the shape of magnetic force lines by changing the number or arrangement of magnets.

Experimental example 1. Magnetic pattern pattern evaluation

For the lipsticks of Example 1 and Comparative Examples 1 to 4 prepared according to the above-described method, a pattern pattern was confirmed using a camera, and this is shown in FIGS. 1 to 3. In each of FIGS. 1 to 3, (a) is Comparative Example 1, (b) is Comparative Example 2, (c) is Example 1, (d) is Comparative Example 3, and (e) is a photograph of Comparative Example 4. . 4 is a photograph of a portion in which the magnetic pattern pattern is not properly implemented, (a) shows Comparative Example 2, (b) shows Example 1, and (c) shows Comparative Example 3.

As shown in Figs. 1 to 3, the magnetic pattern patterns in Comparative Examples 1 and 4 were not clear, and Comparative Examples 2, 3, and Example 1 were relatively clear. Among them, as a result of specifically photographing Comparative Examples 2 and 3 and Example 1 with relatively clear patterns, it can be seen that Example 1 forms a more uniform pattern than Comparative Examples 2 and 3 as shown in FIG. 4.

Experimental example 2. Sensory evaluation

Sensory evaluation of the lipsticks of Example 1 and Comparative Examples 1 to 4 was conducted on 10 professional female panels aged 25 to 45 years. Table 2 shows the results of comparing and evaluating the aesthetics of each lipstick, the pearl expression on the lips, the lasting power and the feeling of use, and evaluating the overall satisfaction.

Among the evaluation criteria, aesthetics refers to the beautiful external properties of the composition itself when embodied as a stick. Expressive power gets a good evaluation score depending on how well the pearl helps the lips feel when applied to the lips. Lasting power means that the color of the composition is maintained for a long time when applied to the lips. When applied to the lips, the feeling of use adheres well and means a freshness without stickiness. These four criteria are evaluation factors that can increase the value of use as a lip makeup cosmetic.

As for the overall satisfaction, as shown in Table 2, Example 1 received the highest score, and Example 1 was mostly evaluated as giving a soft and moist feeling. Next, the overall satisfaction score was shown in the order of Comparative Example 3, Comparative Example 2, Comparative Example 4, and Comparative Example 1. Among them, Comparative Example 3 received an evaluation similar to that of Example 1 in terms of aesthetics, expressiveness, and persistence, but received a considerably low evaluation in terms of feeling of use. Comparative Example 3 had a high pearl content, so it was heavy and stuffy, and there was an evaluation that it applied stiffly.

Accordingly, it can be seen that the lipstick manufactured according to the embodiment of the present invention has excellent expressive power, lasting power, and feeling of use, while implementing a clear and regular pattern pattern.
