Embodiment 1

[0041] Embodiment 1 (preparation eyebrow pencil)

[0042] Color A and color B of the materials described in the following Table 1 were kneaded separately, and the kneaded product was loaded into a core molding machine equipped with a nozzle for core molding at the outlet, and the color A and color B were formed by extrusion and stretching. The kneaded bodies are combined at the front end of the nozzle to form a core body 1 having color stripes 1a, 1b divided into two types in the longitudinal direction. The cross-sectional dimensions of the color stripes 1a, 1b of the core body 1 are 1×1.5 (mm) respectively.

[0043]Next, it heat-processed at 65 degreeC for 3 hours, and made it cool slowly. Afterwards, wait for it to solidify to form the core body 1 . The size of the core body 1 is 1×3 (mm). The core 1 is used as a core that can be sent out successively, and is inserted into a mechanical pencil-shaped continuous feeder 2 to make it as follows: figure 1 Brow pencil 3 shown....

Embodiment 2～9

[0045] Embodiment 2~9, comparative example 1

[0046] In Example 2, except that the heat treatment temperature was 50° C. and in Example 3, the heat treatment temperature was 65° C., eyebrow pencils were prepared in the same manner as in Example 1 according to the recipes shown in Tables 1 to 3 below.

[0047] Reference example

[0048] Except not carrying out heat treatment, similarly to Example 1, eyebrow pencils were prepared according to the prescription shown in following Table 1.

Embodiment 1～3

[0049] About Examples 1-3, the reference example, and the integrity of the eyebrow pencil of Comparative Example 1 were evaluated according to the above-mentioned criteria, and the results are shown in Table 1.

[0050] In addition, for Examples 4 to 9 in which the blending amount of solid oil with a melting point of 70°C to 105°C, semi-solid oil with a melting point of 40°C to 65°C, or solid oil was changed, the states of the obtained cores are shown in Table 2 and Table 2. 3.

[0053]

[0054] ※: Titanium oxide, iron oxide red, iron oxide yellow, and iron oxide black are used in both color A and color B, and the mixing ratio is different for each color.

Abstract

The task of the invention is to provide a pen-shaped cosmetic which has excellent integrity property, is not broken in using, has more than two divided colors in the longitudinal direction and is of a flat core shape, and a manufacturing method thereof. The method for settling the problem according to the invention is that the following components are mixed: 15-35% by mass of solid oil component (a) with melting point of 70-105 DEG C, and 5-35% by mass of semi-solid oil component or solid oil component (b) with melting point of 40-65 DEG C; furthermore more than two cosmetic base preparationswith different colors are integrated in molding for manufacturing into the flat core shape; and finally the heat treatment is performed under the temperature of 50-65 DEG C.

Description

technical field [0001] The present invention relates to pen-shaped cosmetics and a manufacturing method thereof. More specifically, the present invention relates to pen-shaped cosmetics in which two or more colors are separately formed and a method for producing the same. Background technique [0002] Pen-like cosmetics with cores produced by injection molding have been known for a long time. In addition, eyeliners and the like require separate use of two or more types of cosmetics with different colors, so there are problems with portability and operability. In addition, when two or more cosmetics of different colors are to be used separately, it is also conceivable to integrate cores of different colors at both ends of the shaft, but there are complications in operability, design, and the sequential feeding mechanism of the cores. And other issues. [0003] On the other hand, in Patent Document 1, a multi-colored sphere of a certain size is kneaded into a multi-colored ...
