Through the following examples, the present invention is further detailed, but it is obvious that the present invention is not limited by the following examples.

Preparation example: sample preparation

Samples for the experiment were purchased from the market and used. Fermented vegetable oil was prepared by the following method.

Culture medium (glucose 10 g/L, yeast extract 3 g/L, malt extract 3 g/L, peptone 3 g/L, soya bean meal 3 g/L, (NH ₄ ) ₂ SO ₄ 2 g/L, KH ₂ PO ₄ 1 g / L, MgSO ₄ 0.5 g / L, CaCl ₂ 0.1 g / L, NaCl 0.1 g / L) was inoculated with a lactobacillus bifidus strain in 1 L and cultured at 25 ° C., 300 rpm, aerobic conditions.

The culture medium was added with 100 L of olive oil, castor seed oil, or sunflower seed oil, and secondary culture was performed at 25° C., 500 rpm, and aerobic conditions.

After the secondary culture, 0.5 L of the culture medium was taken for each time period, and only the oil portion was recovered.

As essential oils, lavender oil, rosemary oil, and lemongrass oil were commercially available.

Experimental Example 1: Comparison of characteristics according to composition

In order to compare the characteristics according to the composition, examples and comparative examples were set by mixing the samples as follows.

A cosmetic composition having the composition shown in Table 1 below was prepared and a mask pack was prepared using the cosmetic composition.

Jojoba ester as a base oil, olive oil as a vegetable oil, and carnauba wax as a solidifying agent were used.

After weighing the following composition in a beaker, it was uniformly mixed for 5 minutes at 1000 rpm using an agi-homo mixer at a temperature of 85 to 90 °C.

After mixing, the cosmetic composition was transferred to a metered supply pump, sprayed with a comma coating device, and coated with a laminating coating sheet on a roll to cool.

Referring to Table 2, in the case of Examples 1 to 4 in which the content of the solidifying agent was adjusted to the range of 3.0 to 6.0% by weight, it was evaluated to be remarkably excellent in terms of feeling of use, skin solubility, moisturizing feeling, formulation stability, and adhesion.

In particular, Comparative Examples 1 to 3, which had a small content of solidifying agent, were close to liquid formulations, so a semi-solid type mask pack was not implemented, and cosmetic materials flowed down, resulting in reduced usability.

In the case of Comparative Examples 5 and 6, the hardness was excessively high due to the high content of the solidifying agent, and the skin adhesion and solubility were insufficient, and thus the moisturizing sensation was reduced.

The above results suggest that the balm type mask pack according to the present invention can be implemented by appropriately controlling the composition ratio of base oil, vegetable oil, and solidifying agent.

Experimental Example 2: Evaluation of skin moisturizing activity

Skin moisturizing activity was evaluated by changing or adding some oil components to Example 2, which was evaluated as having the most excellent physical properties in Experimental Example 1.

Mask packs were prepared as shown in Tables 3 and 4 below, and the subjects were divided into groups and applied to the face, respectively, and then the skin texture improvement effect was verified.

As the fermented vegetable oil, the lactic acid bacteria fermented vegetable oil prepared in Preparation Example was used, and Comparative Example 7 excluded vegetable oil.

Referring to Table 5, the skin moisturizing activity of Examples 2-3 in which three kinds of vegetable oils were mixed was enhanced, and examples 2-4 to 2-6 and 2-10 to 2-13 in which fermented vegetable oils were introduced. The moisturizing activity of was further enhanced.

In particular, Examples 2-7 to 2-13 to which essential oil was added significantly increased moisturizing activity compared to Examples not including it.

On the other hand, in the case of Comparative Example 7 excluding vegetable oil, synergistic activity according to the introduction of vegetable oil was confirmed in that the skin moisturizing activity was relatively insufficient.

The above results suggest that the mask pack can not only implement excellent physical properties by appropriately controlling the composition ratio of base oil, vegetable oil, and solidifying agent, but also enhance moisturizing activity by adding an introduced oil component.

Experimental Example 3: Moisturizing test

After applying the mask pack prepared according to Tables 3 and 4 to the skin, moisturizing feeling was evaluated, and the results are shown in Table 6.

Moisturizing power was evaluated by measuring the effect of improving skin moisture using Aram Huvis' 'Aramo TS-II' device.

When the value of Table 6 is 39 or less, it means that moisture is insufficient, and when it is about 45 to 55, it means that the moisture condition is good.

Referring to Table 7, it was confirmed that the skin temperature increased by 1.2 to 1.8 ° C according to the lamination layer stacking, and through this, the semi-solid cosmetic composition could be more effectively dissolved.

The above results suggest that the lamination layer effectively dissolves the cosmetic composition of the balm type formulation through a warming effect, and through this, skin absorption of the dissolved cosmetic material can be further promoted.

Experimental Example 5: Skin improvement effect test according to lamination layer application

In Experimental Example 4, skin moisturizing activity was evaluated in the same manner as in Experimental Examples 2 and 3 using the mask pack in which the lamination layers were laminated. The experimental group in which the lamination layer was laminated was marked with the letter “L”.

Experimental Examples 2 and 3 were maintained in all conditions the same except for the lamination layer.

Referring to Tables 8 and 9, the mask pack further increased the skin moisturizing improvement effect according to the lamination layer lamination, and the result was that the lamination layer prevented leakage of dissolved cosmetics through the sheet layer and increased skin temperature, thereby absorbing into the skin. suggests that it can promote

Experimental Example 6: Confirmation of skin improvement activity according to oil component substitution

The jojoba ester used in the experiment was substituted with triethylhexanoin and dimethicone, and Experimental Examples 1 to 5 were repeated.
