Specifically, the pigment may include one or more selected from the group consisting of RED 27 (CI 45410:1) and RED 21 (CI 45380:2).

More specifically, the pigment may include RED 27 and RED 21, and when both of the pigments are included, color development may be more excellent.

The capsule composition of this embodiment may include a pigment in an amount of 0.01 to 3.0% by weight, specifically 0.01 to 2.0% by weight, more specifically 0.02 to 1.0% by weight, based on the total weight of the capsule composition. In particular, when the capsule composition of this embodiment contains a pigment in an amount of 0.02 to 1.0% by weight based on the total weight, the capsule stability, color development power, coloring power, and visual effect due to color reversal may be more excellent.

If the capsule composition of this embodiment contains less than 0.01% by weight of the pigment based on the total weight, the color expression itself is not sufficient, so it may be difficult to utilize it as a color cosmetic composition. On the other hand, when the capsule composition of this embodiment contains more than 3.0% by weight of the pigment based on the total weight, the pigment is not sufficiently dissolved in the solvent, or the pigment uncollected in the capsule remains in the capsule manufacturing process, and the prepared capsule The surface is not smooth, which may cause instability. That is, capsule stability, color development and coloring power may be deteriorated, and it may be difficult to implement a visual effect by color reversal.

The capsule composition of this embodiment contains a solvent.

The capsule composition of this embodiment includes a solvent capable of dissolving the pigment.

Specifically, the solvent may include diisopropyl sebacate (Diisopropyl Sebacate), and in this case, capsule stability may be good, and color development and coloring power may be excellent.

The capsule composition of this embodiment may include 50.0 to 80.0% by weight of the solvent, specifically 55.0 to 75.0% by weight, more specifically 60.0 to 70.0% by weight based on the total weight of the capsule composition. In particular, when the capsule composition of this embodiment contains 60.0 to 70.0% by weight of the total solvent by weight, capsule stability, color development, coloring power, and visual effect by color reversal may be more excellent.

If the capsule composition of this embodiment contains less than 50.0% by weight of the solvent based on the total weight, the pigment may not be sufficiently dissolved, and thus the stability of the capsule, color development power, coloring power and visual effect due to color reversal are reduced. can be lowered In particular, when the dye is sufficiently dissolved in the solvent, it exhibits a transparent color, and a visual effect according to color reversal can be realized according to the destruction of the capsule. Since the color appears, it may be difficult to implement the color reversal effect according to the destruction of the capsule.

On the other hand, when the capsule composition of this embodiment contains more than 80.0 wt % of the solvent based on the total weight, the capsule itself may not be stably formed.

The capsule composition of this embodiment includes a capsule film forming agent.

The capsule composition of this embodiment includes a capsule film-forming agent, and the capsule film-forming agent may form a capsule by forming a shell for collecting a solvent in which a pigment is dissolved.

Specifically, the capsule film forming agent of this embodiment may include an acrylate/C10-30 alkyl acrylate crosspolymer (Acrylates/C10-30 Alkyl Acrylate Crosspolymer), and in this case, capsule stability may be excellent.

The capsule composition of this embodiment may contain 1.0 to 12.0% by weight of the capsule film forming agent, specifically 1.5 to 11.0% by weight, more specifically 2.0 to 10.0% by weight, based on the total weight of the capsule composition. In particular, when the capsule composition of this embodiment contains 2.0 to 10.0% by weight of the capsule film forming agent based on the total weight, the visual effect by capsule stability, color development power, coloring power and color reversal may be more excellent.

If, based on the total weight of the capsule composition of this embodiment contains less than 1.0% by weight of the capsule film forming agent, or contains more than 12.0% by weight, it may be difficult to form the capsule itself.

The capsule composition of this embodiment may further include a dissolution aid.

Specifically, the capsule composition of this embodiment further includes a dissolution aid, so that the pigment can be stably dissolved in the solvent, thereby improving capsule stability, color development power, coloring power, and visual effects by color reversal.

The dissolution aid of this embodiment may include one or more selected from the group consisting of grape seed oil, meadowfoam seed oil, avocado oil, sorbitol, maltitol, glycerin and propylene glycol.

Specifically, the dissolution aid of this embodiment may include grape seed oil, meadowfoam seed oil and sorbitol, and in this case, the pigment is effectively dissolved in the solvent, and the visual effect by capsule stability, color development power, coloring power and color reversal is more can be improved

More specifically, the dissolution aid of this embodiment may include grape seed oil, meadowfoam seed oil, and sorbitol in a weight ratio of 1: 10 to 15: 1 to 5, and in this case, the pigment is more effectively dissolved in the solvent, and the capsule Stability, color development, coloring power, and visual effects by color inversion can be significantly improved.

The capsule composition of this embodiment may include 3.0 to 6.0% by weight of the dissolution aid, specifically 3.5 to 5.5% by weight, more specifically 4.0 to 5.0% by weight, based on the total weight of the capsule composition. In particular, when the capsule composition of this embodiment contains 4.0 to 5.0% by weight of the dissolution aid based on the total weight, the visual effect by capsule stability, color development power, coloring power and color reversal may be more excellent.

If the capsule composition of this embodiment contains less than 3.0% by weight of the dissolution aid based on the total weight, the effect of improving the solubility of the pigment may be insignificant. On the other hand, when the capsule composition of this embodiment contains more than 6.0% by weight of the dissolution aid based on the total weight, the capsule cannot be stably formed, so color development power, coloring power, and visual effect due to color reversal may not be sufficiently implemented. have.

The capsule composition of this embodiment may further include a residual amount of water. The water may cause the shell to be formed by the capsule wall forming agent when each component is mixed.

The capsule composition of this embodiment may further include a preservative, but is not limited thereto. For example, the preservative may include 1,2-hexanediol, but is not limited thereto.

[Example]

Example 1

According to Table 1 [unit: wt%], each component was mixed to prepare a capsule composition containing a capsule.

Specifically, the tint dye (RED21,27) and diisopropyl sebacate are mixed, and in a solution dissolved by heating and stirring (temperature: 50 to 80° C., stirring speed: 200 to 500 rpm), acrylate/C10- 30 alkyl acrylate crosspolymer and water were added, and heating and stirring (temperature: 80° C. or higher, stirring speed: 2,000 to 3,000 rpm) were performed, and O/W emulsification was performed.

Then, when the capsule film is formed, it is cooled to 30° C. or less, 1,2-hexanediol is added, mixed at a room temperature of about 25° C. at a stirring speed of 200 to 500 rpm, and then defoamed to contain the capsule. One capsule composition was prepared.

Examples 2 to 7

By mixing each component according to Table 2 [unit: wt%], a capsule composition containing a capsule was prepared.

At this time, the manufacturing method was the same as in Example 1, but it was prepared by additionally adding a dissolution aid together with the tint pigment.

In this case, as the dissolution aid in Table 2, a mixture of grape seed oil, meadowfoam seed oil and sorbitol according to Table 3 [unit: weight ratio] was used.

In addition, the '-' mark in Table 3 means that the corresponding component is not included. That is, Example 2 refers to a case in which only grape seed oil is included.

[ Comparative Example ]

Comparative Examples 1 to 2: Evaluation according to the type of solvent

It proceeded in the same manner as in Example 1 except that the solvent of Table 4 was used.

Comparative Examples 5 to 10: Evaluation according to content

Except that each component was mixed in Table 5 [unit: wt%], the same procedure as in Example 1 was carried out.

[ to the experiment ]

Experimental Example 1: Selection of solvent

(1) Compatibility evaluation with pigments

In Examples 1 to 7 and Comparative Examples 1 to 4, after mixing each component and before manufacturing the capsule, the pigment was sufficiently dissolved in the solvent to become transparent, and visually observed, the results are shown in Table 6 it was That is, it shows the observation result of a state in which only the solvent and the dye are mixed, and in the case of Examples 2 to 7, the observation result of the state in which the dissolution aid is also mixed together.

In addition, the results of Example 1, Comparative Example 1 and Comparative Example 2 are shown in FIGS. 1 and 2, and FIGS. 1 and 2 are views showing the results of Example 1, Comparative Example 1, and Comparative Example 2 sequentially.

Referring to Table 6 and FIGS. 1 to 2, in the case of Examples 1 to 7 according to the present embodiment, it can be confirmed that the pigment is dissolved in the solvent and formed in a transparent state. On the other hand, in Comparative Examples 1 and 3, which does not follow this example, the pigment was not properly dissolved and dispersed, so it was formed in an opaque state, and in Comparative Examples 2 and 4, it can be seen that the pigment was dissolved and color was expressed. .

(2) Evaluation of color expression performance when in contact with a subject

By applying the mixture of the solvent and the dye used in (1) of Experimental Example 1 to the subject (tint expression body), it was visually observed whether the color was expressed, and the results are shown in Table 7.

In addition, the results of Example 1, Comparative Example 1, and Comparative Example 2 are shown in FIG. 3, and FIG. 3 is a view showing the results of Example 1, Comparative Example 1, and Comparative Example 2 sequentially.

Referring to Table 7 and FIG. 3 , in the case of Examples 1 to 7 according to this embodiment, it can be confirmed that the color of the dye is expressed when the dye is dissolved in the solvent while maintaining a transparent state, and in contact with the object.

On the other hand, in Comparative Examples 1 and 3, which do not follow this example, it can be seen that when the pigment is dissolved in the solvent, it is in an opaque state, and the color is not properly expressed even when it comes into contact with the object. In addition, in the case of Comparative Examples 2 and 4, since the color expression state immediately after the dye is dissolved in the solvent, it can be seen that a clear color is expressed even when in contact with the object.

That is, looking at the experimental results, according to the present example, when diisopropyl sebacate is used as a solvent, the transparent state is maintained immediately after preparation, and the color is expressed upon contact with the skin, thereby providing a visual effect by color reversal. It can be seen that this can be implemented.

Experimental Example 2: Capsule Preparation and Stability Evaluation

(1) Manufacturing stability of capsules

After preparing a capsule composition according to the Examples and Comparative Examples, it was observed with the naked eye and an electron microscope whether the capsule was stably formed, and the results are shown in Table 8. At this time, when the capsule is spherical and has an appropriate size and the surface is made smooth, it was evaluated as 'stable'. In the case of 'unstable', it was evaluated and shown in Table 8.

In addition, an enlarged observation of the capsule composition of Example 1 with an electron microscope (OLYMPUS BX53) is shown in FIG. 4, and an enlarged observation of the capsule composition of Comparative Example 6 with an electron microscope is shown in FIG. 5 .

Referring to Table 8 and FIGS. 4 to 5, it can be seen that, according to the present embodiment, the pigment is sufficiently dissolved in the solvent and collected in the capsule (transparent portions other than the capsule), thereby forming a capsule in a stable state.

On the other hand, when this embodiment is not followed, the surface of the capsule is not smooth, non-uniform, and it is observed in the residual pigment not collected in the capsule (parts other than the capsule opaque), and it can be seen that the capsule is in an unstable state.

(2) high temperature stability

Whether the prepared capsule can maintain a stable state, was evaluated, and the results are shown in Table 9.

Specifically, while the prepared capsule composition was left at about 50° C. for about 4 weeks, the state of the capsule composition was observed at intervals of 1 week, and the results are shown in Table 9.

Referring to Table 9, it can be seen that, according to the present embodiment, the capsule stability is excellent even when left at a high temperature for about 3 weeks or more. In particular, in the case of Example 5, which contains grape seed oil, meadowfoam seed oil, and sorbitol oil in a weight ratio of 1: 10 to 15: 1 to 5 as dissolution aids, it can be seen that stability at high temperature is further improved.

Experimental Example 3: Evaluation of color development and coloring power

(1) Evaluation of color development

When the capsule compositions of Examples and Comparative Examples were applied to the tint expression body, the degree of pigment expression while the capsule was destroyed was evaluated by a 5-point method, and the results are shown in Table 10 [unit: score]. Specifically, in the evaluation of color development, each capsule composition was applied to the back of the hand to a group of 10 women, in their 20s and 30s, to evaluate the degree of color development, and the average value is shown in Table 10.

In addition, the evaluation result of the color development of the capsule composition of Example 5 is shown in FIG.

(2) Coloring power evaluation

After (1) evaluation of color development, the back of the hand was lightly washed with running water, and then the water was removed using a tissue.

Referring to Table 10, according to the present embodiment, the color development power and the coloring power may be excellent.

Also, referring to FIG. 6 , it can be seen that the capsule composition of Example 5 maintains a transparent state before applying an external force (left), and when an external force is applied (right), the capsule bursts and develops color.
