Background Technology

[0003] Interest is focused on hair, makeup, skincare, weight control, fashion, and plastic surgery to manage the ideal appearance that individuals pursue.

[0004] In particular, the face can be the first thing that allows others to recognize you, and emotions such as annoyance, anger, and joy can be immediately read through facial expressions.

[0005] The forehead, eyes, nose, mouth, cheeks, and chin, which make up the shape of the face, give various images depending on types such as shape and size.

[0006] Among facial features, eyebrows—which are muscles used to create expressions—have come to significantly influence changes in facial image in the current era of increased mask usage due to COVID-19. Having too few or too many eyebrows is uncomfortable, and asymmetry, or having one side higher or lower than the other, creates a poor impression. People devote considerable effort and care to creating symmetrical and balanced eyebrows. Depending on the density, length, and shape of the eyebrows, one's impression changes significantly and even affects internal psychological states such as self-confidence.

[0007] Therefore, there is a need for technological development of hydrogels for eyebrow growth products that can increase eyebrow density and thickness, and enhance skin improvement, moisturizing, and psychological stability effects. Prior art literature

[0055] At this time, it is preferable that the content of carboxymethyl cellulose be 0.1 to 5 parts by weight per 100 parts by weight of distilled water, and when the content satisfies the above numerical range, the eyebrow hair growth effect can be maximized.

[0056] In addition, the above cellulose solution may further include hydroxymethyl cellulose.

[0057] At this time, the content of hydroxymethyl cellulose is preferably 0.1 to 5 parts by weight per 100 parts by weight of distilled water, and when the content satisfies the above numerical range, the eyebrow hair growth effect can be maximized.

[0058] In addition, the cellulose solution may further include hydroxypropyl cellulose.

[0059] At this time, it is preferable that the content of hydroxypropyl cellulose be 0.1 to 5 parts by weight per 100 parts by weight of distilled water, and when the content satisfies the above numerical range, the eyebrow hair growth effect can be maximized.

[0061] Step (d) above can be used to prepare a hydrogel by adding a crosslinking agent to the cellulose solution and then proceeding with the crosslinking reaction.

[0062] In step (d) above, 0.01 to 5 parts by weight of a crosslinking agent may be added to 100 parts by weight of a cellulose solution. When the content satisfies the above numerical range, the eyebrow hair growth effect can be maximized.

[0074] In addition, the present invention relates to an aroma hydrogel for eyebrow hair growth products manufactured by the above manufacturing method.

[0075] In addition, the present invention relates to an eyebrow hair growth agent comprising the above-mentioned aroma hydrogel for eyebrow hair growth agents.

[0076] The present invention can provide a hydrogel for eyebrow hair growth that can be manufactured easily and simply, and can increase the density and thickness of eyebrows, and improve skin improvement effects, moisturizing effects, psychological stability effects, etc.

[0077] The aroma hydrogel of the present invention can be used as an eyebrow growth agent because it increases the density and thickness of eyebrows and has excellent skin improvement, moisturizing, and psychological stabilization effects.

[0079] The present invention will be described in detail below through examples and comparative examples. The following examples are merely illustrative for the implementation of the present invention, and the scope of the present invention is not limited by the following examples.

[0081] (Example 1)

[0082] A first solution was prepared by mixing 100 parts by weight of distilled water and 5 parts by weight of beta-cyclodextrin.

[0083] 100 parts by weight of the first solution and 2 parts by weight of cinnamon oil were mixed and reacted, and then the solvent was removed to produce an aroma oil powder.

[0084] A cellulose solution was prepared by mixing 100 parts by weight of distilled water and 5 parts by weight of hydroxyethyl cellulose (HEC).

[0085] A hydrogel was prepared by adding 1 part by weight of a 0.5M citric acid solution to 100 parts by weight of the above cellulose solution and then proceeding with a crosslinking reaction.

[0086] An aroma hydrogel was prepared by adding 5 parts by weight of the aroma oil powder to 100 parts by weight of the above hydrogel.

[0088] Figure 1 shows the viscosity of the aroma hydrogel of the present invention.

[0089] Generally, the viscosity of many liquids falls within the range of about 0.5 to 1,000 cP, and within this range, the higher the viscosity, the thicker the properties.

[0090] The viscosity of the aroma hydrogel of the present invention was measured at 992.2 cP, indicating a high viscosity corresponding to the upper end of the range.

[0091] These figures indicate that the eyebrow growth agent of the present invention is in a relatively thick and highly viscous state, and due to its viscosity characteristics, it can provide the property of remaining on the eyebrows continuously without dripping when attached.

[0093] Figure 2 shows the SEM analysis results of the aroma hydrogel of the present invention.

[0094] Beta-cyclodextrin (a) has a rough surface, and in the case of aroma oil powder (b) in which aroma oil is encapsulated in beta-cyclodextrin, it can be seen that it is well bound to the surface in a rhombus shape.

[0095] This means that the encapsulation of aroma oils into beta-cyclodextrin proceeded successfully.

[0097] Figure 3 shows the change in eyebrows when using the aroma hydrogel of the present invention.

[0098] Figure 3 visually compares the changes in eyebrow condition before and after using aroma hydrogel, and presents two cases of the most noticeable changes among the 10 participants in the experiment.

[0099] The experiment was conducted by applying an aroma hydrogel eyebrow hair growth agent only to the right eyebrow of each subject to compare the difference between the eyebrows to which the hair growth agent was applied and the eyebrows to which it was not applied.

[0100] The right eyebrow, to which the hair growth agent was applied, showed an increase in visible density compared to before use, and the eyebrow density increased compared to before, and the growth of fine hairs was also observed. On the other hand, the left eyebrow, to which the hair growth product was not applied, did not show such changes, making the difference relatively pronounced.

[0101] These results suggest that the arama hydrogel eyebrow growth agent of the present invention is effective in increasing eyebrow density and promoting eyebrow growth.

[0103] Figure 4 shows the change in average density before and after using the aroma hydrogel eyebrow hair growth agent of the present invention, and Figure 5 shows the change in average thickness.

[0104] According to the average density results in Figure 4, the average density value of 10 subjects before use was 7.0, which corresponds to a 'high' level, and after using the eyebrow hair growth product, the average density value increased to 8.5, which was found to be a 'very high' level.

[0105] This suggests that, on average, eyebrow hair increased in the subjects' eyebrows after the application of the eyebrow growth agent of the present invention. In other words, it can be seen that the growth agent had a positive effect on eyebrow density and demonstrated an eyebrow hair growth-promoting effect.

[0106] In addition, in the average thickness results of Figure 5, the average thickness value of 10 subjects before use was 8.5, which corresponds to the 'thick hair' level, and after using the eyebrow growth product, the average thickness value was 10.0, which corresponds to the 'very thick hair' level.

[0107] This result confirms that the thickness of the eyebrow hairs increased after using the eyebrow hair growth agent of the present invention.

[0108] Therefore, it can be concluded that the aroma hydrogel of the present invention had a positive effect not only on the density but also on the thickness of the eyebrows. This change suggests that the components of the hair growth agent helped promote the growth and thickness of the eyebrow hairs.

[0110] (Example 2)

[0111] An aroma hydrogel was prepared in the same manner as in Example 1, except that 0.5 parts by weight of beta-cyclodextrin was used.

[0113] (Example 3)

[0114] An aroma hydrogel was prepared in the same manner as in Example 1, except that 12 parts by weight of beta-cyclodextrin were used.

[0116] (Example 4)

[0117] An aroma hydrogel was prepared in the same manner as in Example 1, except that a cellulose solution was prepared by adding 1 part by weight of carboxymethyl cellulose (CMC).

[0119] (Example 5)

[0120] An aroma hydrogel was prepared in the same manner as in Example 1, except that 0.7 parts by weight of citric acid solution and 0.3 parts by weight of malic acid solution were used instead of 1 part by weight of citric acid solution.

[0122] (Comparative Example 1)

[0123] A hydrogel was prepared in the same manner as in Example 1, except that aroma oil powder was not used.

[0125] The characteristics of the aroma hydrogels prepared from the above examples and comparative examples were evaluated and are shown in Table 1 below.

[0126] To evaluate the effectiveness of the manufactured aroma hydrogel eyebrow hair growth product on 10 subjects, skin and scalp analyses were performed after 12 weeks of use.

[0127] Each subject applied a hair growth agent to their right eyebrow once a day after washing their face, and changes in skin and scalp condition were evaluated using an A-ONE TAB device, with the main measurement items set as skin moisture, elasticity, eyebrow density, and changes in thickness.

[0128] A consistent analysis was conducted by selecting a measurement area within a 0.5 cm section 3 to 3.5 cm away from the front of the eyebrow.

[0130] eyebrow density Eyebrow thickness Example 1 8.5 10.0 Example 2 7.8 9.4 Example 3 7.9 9.3 Example 4 8.8 10.6 Example 5 9.0 11.1 Comparative Example 1 7.3 8.7

[0132] From the results of Table 1 above, it can be seen that Examples 1 to 5 have excellent eyebrow density and eyebrow thickness, and in particular, Examples 1, 4, and 5 have the best characteristics.

[0133] On the other hand, it can be seen that Comparative Example 1 has inferior characteristics compared to the Example.
