Hydrogel pack containing dry plant

The present invention relates to a hydrogel pack comprising dry plants such as flowers, wildflowers, herbs, succulents, seaweeds, leaves.

The pack for skin beauty may be divided into a form of a mask pack attached to the entire face and a patch form attached to skin other than the face or a part of the face such as an eye patch, a nose pack, a lip patch, and a body patch. In general, a pack for skin care is formed in a form of impregnating a skin care solution on a sheet such as a nonwoven fabric, fiber, or rayon. However, such a pack has a problem of low adhesion to the skin and low adhesion, and insufficient delivery of active ingredients. Accordingly, in recent years, the use of a hydrogel pack, which has excellent adhesion to the skin and excellent adhesion, has improved delivery power of active ingredients.

), When pulled 5 times at the same time, the shape of the dried plant in the hydrogel pack is preserved as the first time (very good). In this difficult case (very bad), it was designated as X, and the results are shown in Table 8.

In addition, experiments of Examples 2 to 12 and Comparative Examples 1 to 10 were performed in the same manner as in Example 1, and the results are shown in Table 8.

[Table 8]

Looking at Table 8, in accordance with this embodiment, it can be seen that despite the deformation of the hydrogel pack, the shape of the dried plant is well maintained as in the beginning. That is, in the case of following this embodiment, it means that the shape preservation power of the dried plant is improved.

(2) Color change evaluation

While leaving the hydrogel pack containing the dried plant prepared according to Examples and Comparative Examples at room temperature for up to 12 weeks, the color change of the dried plant in the hydrogel pack was observed with the naked eye to evaluate the color change results. It is shown in 9.

As a result of observation with the naked eye, when the dried plant was not discolored (very good), ○, when discoloration occurred in some areas of the dried plant, △, when the dried plant was discolored as a whole (very bad), it was designated as X. Table 9 shows the results.

[Table 9]

Referring to Table 9, it can be confirmed that the occurrence of discoloration was prevented according to the present embodiment.

According to Tables 8 and 9, according to the present embodiment, it means that the shape of the dried plant can be maintained as in the beginning.

실험예 4 : 피부 유효 성분 전달력 평가Experimental Example 4: Skin active ingredient delivery power evaluation

After attaching the hydrogel pack of Example 1 to the face for about 20 minutes, it was removed and the degree of improvement in skin tone (brightness) was evaluated using a Roboskin analyzer.

The test was conducted on 5 subjects. The test subject was a woman of average age 34 years old, and was composed of people with skin tone [unit: gradation] of about 65 to 67 when skin tone was measured with the above-mentioned equipment.

The test subject was to use the hydrogel pack of Example 1 3 times a week, and after about 6 weeks, the skin tone was measured 5 times, and the average value was calculated and shown in Table 10. The test was conducted in a constant temperature and humidity room with a humidity of 45 to 55% at 20 to 24 ° C. After washing, the skin tone was measured after adaptation for at least 1 hour in the constant temperature and humidity room.

The degree of skin tone improvement of Examples 2 to 12 and Comparative Examples 1 to 10 was evaluated in the same manner as above, and the results are shown in Table 10.

Table 10

Looking at Table 10, it can be seen that according to the present embodiment, the degree of improvement in skin tone is more excellent. That is, the hydrogel pack of the present embodiment means that the effect of improving the skin by delivering an active ingredient to the skin is remarkably excellent.

Summarizing the contents of the above Experimental Examples 1 to 4, according to the present embodiment, as well as improving the effects of the tensile strength, elongation, skin adhesion and adhesion of the hydrogel pack, the deformation of the dried plant is prevented, and the skin It can be seen that the effect of delivering the active ingredient is excellent.
