[0039] Step (a) above can prepare a first solution by mixing distilled water, alcohol, and beta-cyclodextrin.

[0040] The first solution above may comprise 100 parts by weight of distilled water, 30 to 80 parts by weight of alcohol, and 5 to 30 parts by weight of beta-cyclodextrin. When the content satisfies the above numerical range, the skin improvement effect can be maximized.

[0041] The above alcohol may be methanol, ethanol, isopropyl alcohol, butanol, etc.

[0047] Step (b) above can prepare a second solution by mixing alcohol and aroma oil.

[0048] The second solution above may contain 100 parts by weight of alcohol and 2 to 20 parts by weight of aroma oil. If the content satisfies the above numerical range, the skin improvement effect can be maximized.

[0054] Step (c) above can produce an aroma oil powder by mixing the first solution and the second solution.

[0055] Aroma oil powder can be obtained by mixing 100 parts by weight of the first solution and 10 to 40 parts by weight of the second solution, reacting them, and then removing the solvent.

[0057] Step (d) above can prepare a cellulose solution by mixing distilled water, hydroxyethyl cellulose (HEC), and carboxymethyl cellulose (CMC).

[0058] The above cellulose solution may comprise 100 parts by weight of distilled water, 0.1 to 10 parts by weight of hydroxyethyl cellulose (HEC), and 0.1 to 10 parts by weight of carboxymethyl cellulose (CMC). When the content satisfies the above numerical range, the skin improvement effect can be maximized.

[0059] At this time, it is preferable that the weight ratio of hydroxyethyl cellulose (HEC) and carboxymethyl cellulose (CMC) be 1:1 to 6. When the weight ratio satisfies the above numerical range, the skin improvement effect can be maximized.

[0060] The above hydroxyethyl cellulose (HEC) and carboxymethyl cellulose (CMC) can form a hydrogel through a crosslinking reaction with a crosslinking agent.

[0061] In addition, the cellulose solution may further include hydroxymethyl cellulose.

[0062] At this time, it is preferable that the content of hydroxymethyl 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 skin improvement effect can be maximized.

[0069] It is preferable that the concentration of citric acid contained in the above citric acid solution be 0.1 to 5 M.

[0070] In addition, the present invention may use a mixture of a citric acid solution and a malic acid solution as a crosslinking agent.

[0071] At this time, it is preferable that the weight ratio of the citric acid solution and the malic acid solution be 60~80:20~40, and when the weight ratio satisfies the above numerical range, the skin improvement effect can be maximized.

[0072] In addition, the present invention may use a mixture of citric acid solution, malic acid solution, and maleic acid solution as a crosslinking agent.

[0084] The present invention can provide an aroma hydrogel for mental care, skin care, and inflammation care that can be manufactured easily and simply, and can improve skin improvement effects, moisturizing effects, psychological stability effects, etc.

[0085] The aroma hydrogel of the present invention has excellent skin improvement, moisturizing, and psychological stabilization effects, and can be used as a wet tissue, mask pack, cosmetic, deodorizer, aroma solution, etc.

[0087] 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.

[0089] (Example 1)

[0090] A first solution was prepared by mixing 100 parts by weight of distilled water, 45 parts by weight of ethanol, and 20 parts by weight of beta-cyclodextrin.

[0091] A second solution was prepared by mixing 100 parts by weight of ethanol and 10 parts by weight of lemon oil.

[0092] Aroma oil powder was prepared by mixing 100 parts by weight of the first solution and 30 parts by weight of the second solution, reacting them, and then removing the solvent.

[0093] A cellulose solution was prepared by mixing 100 parts by weight of distilled water, 2 parts by weight of hydroxyethyl cellulose (HEC), and 6 parts by weight of carboxymethyl cellulose (CMC).

[0094] A hydrogel was prepared by adding 0.5 parts by weight of a 0.5 M citric acid solution to 100 parts by weight of the above cellulose solution and then proceeding with a crosslinking reaction.

[0095] 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.

[0097] Figure 1 shows the viscosity of the aroma hydrogel of the present invention.

[0098] As the shear rate increases, the viscosity decreases, which means that the hydrogel adheres easily to the skin and its fluidity increases during use.

[0099] The viscosity at a shear rate of 2 is 8,731 cP, which represents the state of the wet tissue when it is packaged or handled slowly. 8,731 cP is a moderately high viscosity value that allows the wet tissue to maintain a gel state before use while keeping it from drying out and maintaining sufficient moisture.

[0100] The viscosity at a shear rate of 12 is 3,737 cP, representing the state when applying pressure with the hand or applying it to the skin when using the wet tissue. It is a viscosity where the wet tissue becomes appropriately soft and spreads easily on the skin without flowing like water during use. This value provides sufficient fluidity when applied to the skin, improving the user experience.

[0101] Therefore, the measured viscosity of the functional aroma hydrogel appears to be suitable for use in wet tissues, and it can be confirmed that this is a viscosity within an appropriate range that allows the wet tissue to maintain its moisturizing function while being applied gently during use.

[0103] Figure 2 shows the SEM analysis results of the functional aroma hydrogel.

[0104] Beta-cyclodextrin (a) exhibits an irregular stone shape, and in the case of aroma oil powder (b) in which aroma oil is encapsulated in beta-cyclodextrin, the original shape of the beta-cyclodextrin disappears and is transformed into a smooth, angular square or rhombus shape.

[0105] This means that the encapsulation of aroma oils into beta-cyclodextrin proceeded well, and it can be confirmed that the powder particles have also become much finer.

[0107] Figure 3 shows the results of a wrinkle test on a functional aroma hydrogel wet tissue.

[0108] After preparing a wet tissue using the functional aroma hydrogel of the present invention, it was attached to the skin for 2 hours and then removed. Subsequently, a total of six indicators—pores, wrinkles, pigmentation, oiliness, moisture, and elasticity—were measured using a skin tester (A-ONE TAB). The inner arm skin of a total of 20 male and female subjects aged 20 to 40 was measured using a skin tester (A-ONE TAB).

[0109] Figure 3 shows the wrinkle test results of two representative subjects from each age group out of a total of 20 male and female subjects in their 20s to 40s. By comparing the respective figures, it can be confirmed that the wrinkle levels decreased after using the wet tissue.

[0110] Therefore, it can be seen that functional aroma hydrogel wet tissues are effective in reducing wrinkles.

[0112] (Example 2)

[0113] An aroma hydrogel was prepared in the same manner as in Example 1, except that 5 parts by weight of hydroxyethyl cellulose (HEC) and 3 parts by weight of carboxymethyl cellulose (CMC) were used instead of 2 parts by weight of hydroxyethyl cellulose (HEC) and 6 parts by weight of carboxymethyl cellulose (CMC).

[0115] (Example 3)

[0116] An aroma hydrogel was prepared in the same manner as in Example 1, except that 1 part by weight of hydroxyethyl cellulose (HEC) and 8 parts by weight of carboxymethyl cellulose (CMC) were used instead of 2 parts by weight of hydroxyethyl cellulose (HEC) and 6 parts by weight of carboxymethyl cellulose (CMC).

[0118] (Example 4)

[0119] 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 hydroxymethyl cellulose.

[0121] (Example 5)

[0122] An aroma hydrogel was prepared in the same manner as in Example 1, except that 0.35 parts by weight of citric acid solution and 0.15 parts by weight of malic acid solution were used instead of 0.5 parts by weight of citric acid solution.

[0124] (Comparative Example 1)

[0125] A hydrogel was prepared in the same manner as in Example 1, except that aroma oil powder was not used.

[0127] The characteristics of the aroma hydrogels prepared from the above examples and comparative examples were evaluated and are shown in Table 1 below.

[0128] After preparing a wet tissue using the above-mentioned functional aroma hydrogel, the tissue was attached to the skin for 2 hours and then removed, after which the characteristics of wrinkles, moisture, and elasticity were measured using a skin tester (A-ONE TAB). The inner arm skin of a total of 20 male and female subjects aged 20 to 40 was measured using a skin tester (A-ONE TAB).

[0130] Wrinkle characteristics Moisture characteristics Elasticity Example 1 0.7 36.7 44.5 Example 2 1.3 31.5 37.9 Example 3 1.4 30.8 38.3 Example 4 0.5 39.6 47.2 Example 5 0.6 40.1 48.8 Comparative Example 1 2.1 28.7 36.0

[0132] From the results of Table 1 above, it can be seen that Examples 1 to 5 have excellent skin wrinkle characteristics, moisture characteristics, and elasticity characteristics, 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.
