Description

[0001] The present invention relates to a composition for skin cooling comprising phlorotannin as an active ingredient,

The present invention relates to a method for cooling skin which can be applied to the skin to improve discomfort caused by external stimuli such as heat, ultraviolet rays, yellow dust, fine dust, etc., and heat caused by exercise, labor, To compositions and products containing them. And more particularly to compositions and products that have no side effects without preservatives and that have a continuous effect rather than instant cooling effects such as coolants and menthol.

Due to recent industrial developments, the average temperature rises every year, and the record heat of summer is continuing due to global warming. As a result, skin fever due to heat and ultraviolet rays causes discomfort and causes redness and reddening of the skin, resulting in inconvenience to the social life. Such skin fever can be caused not only by heat but also by exercise, labor, emotional upset, hormonal abnormality, yellow dust, fine dust, etc., which also causes discomfort and deteriorates body efficiency.

Currently, there are many products distributed for the purpose of skin cooling. One of them, mask pack, is a packed mask sheet containing one dose of liquid essence. In the case of a mask pack product having an effect of skin cooling, it contains a cooling stick or raw materials such as menthol and mint which give a cool feeling. A mask pack with a cooling stick is used to cool the mask prior to use, cooling the mask pack to provide a cooling effect when applied to the skin. However, when a cold mask pack is applied to the surface of the skin, it immediately feels cool, but there is a drawback that only a temporary effect can be expected. On the other hand, a mask pack containing ingredients such as menthol and mint also stimulates the cooling receptors of the nerve endings to provide a temporary feeling of coolness, but not a substantial cooling effect, and it is difficult to expect a sustained effect. In addition, consumers who dislike stimuli or incense may feel uncomfortable to use. In addition, most mask packs add preservatives to prevent deterioration of the product during storage, which can cause serious side effects.

(Korean Patent Laid-Open Publication No. 10-2007-7007261, Korean Patent Laid-open No. 10-2009-7007276) discloses a method for dissolving the skin which can cool the skin during the skin fever ≪ / RTI > However, since it is necessary to use a high concentration of organic compound for cooling the skin, there is a possibility of destroying the oil film which is a skin barrier when applied to the skin, and there is a risk of side effects occurring in the chemical. In addition, there is a drawback in that the use of a high concentration of the composition limits the development of various products.

Therefore, it is required to research and develop a product that is free of irritation and easy to use because it does not contain a composition and a preservative that can directly and continuously cool the skin without affecting the oil film existing on the skin and can expect a direct and continuous cooling effect In fact.

(Patent Publication 1) Korean Patent Publication No. 10-2007-7007261 (Published Patent 2) Korean Patent Publication No. 10-2009-7007276

The present invention provides a composition and a product for skin cooling which have a safe and continuous effect that can be applied to skin to improve skin heat due to heat, ultraviolet rays, yellow dust, fine dust, emotion elevation, hormone abnormality, , Side effects due to chemicals, short duration of cooling, and the like. In addition, the product is applied in various forms such as a liquid essence, a mist, and a sheet mask pack, so that it is convenient to use without restriction of place and time.

In order to prepare a composition containing the phlorotannin of the present invention as an active ingredient, the brown algae of the present invention were extracted by the following method.

Ecklonia cava was washed with distilled water to remove foreign matter, dried in shade, and then shattered. 500 g of the above menthol was added to the extraction vessel, 20 times of 30 wt% aqueous solution of menthol was added thereto, and the mixture was refluxed for extraction at 75 to 80 ° C for 4 hours to obtain an extract. The extract was filtered through a filter net of 10 mu m, and the filtered extract was concentrated under reduced pressure to obtain a primary extract concentrate. The primary extract concentrate was dried with a vacuum drier and pulverized to obtain 170 g of a primary extract.

The primary extract was dissolved in hot water at 50 캜, adsorbed on an adsorbent resin, washed with water, and eluted with a solvent to obtain a fluorotannin eluate. The eluate was filtered through a 1 탆 filter net, and the filtered extract was concentrated under reduced pressure to obtain a second extract concentrate. The second extracting concentrate was dried with a vacuum drier and pulverized to obtain 30 g of a secondary extract.

Then, the second extract was suspended in 20 times of distilled water and extracted three times with the same amount of ethyl acetate solvent to obtain an ethyl acetate fraction. The ethyl acetate fraction was concentrated under reduced pressure, and the concentrate was dried with a vacuum drier and pulverized to obtain 10 g of Composition 1.

Composition 1 was dissolved in 30 vol.% Methanol and then compositions 2 and 3 were separated using reverse phase chromatography. Separation was carried out by using a 15 to 80% by volume methanol aqueous solution, and 2 g of the composition 2 was obtained by concentrating the solution separated by the aqueous methanol solution having a concentration of 15 to 30% by volume, and the separated solution in the aqueous methanol solution having a concentration of 30 to 80% To obtain 7 g of Composition 3.

Each of the compositions 1 to 3 prepared above was loaded onto liquid chromatography to proceed with compound separation. The compounds thus obtained were identified as the compounds of the formulas (1) to (12) using the NMR spectroscopic analysis apparatus. Each of the compositions 1 to 3 prepared above was dissolved in 60% by volume methanol, filtered through a 0.2 μm membrane filter, and loaded onto high performance liquid chromatography. In high performance liquid chromatography, HP ODS Hypersil was used as the column, distilled water and methanol were used as the solvent, and the solvent was fed from a linear gradient of from 15 vol% to 70 vol% of methanol for 30 minutes at a flow rate of 1.0 ml / ). As a result, the presence of the compounds of Formulas 1 to 12 was confirmed. The chemical compositions of the above-mentioned compositions 1 to 3 are shown in Table 1 below.

30 subjects (12 males and 18 females) were exposed to physical activity for more than 10 minutes to induce skin fever, and the subjects were placed in a comfortable posture and stabilized for 10 minutes. The skin surface temperature was measured using an infrared thermometer (Sincon, ST-102) after randomly dividing into 6 groups (pre-application temperature). To evaluate the skin cooling effect, compositions 1 to 3, mint extract (Comparative Example 1) and menthol extract (Comparative Example 2) were dissolved in purified water at a ratio of 0.1 wt% to prepare respective aqueous solutions. Further, purified water was used as Comparative Example 3. Before applying the aqueous solution of each composition and the comparative example to the skin, the temperature was allowed to stand at room temperature for 2 hours, and the temperature was measured immediately before application to the skin. The surface temperature of the skin on the left cheek was measured immediately after application (1 cc) of each composition of Example 1 and each of the Comparative Examples 1 to 3 aqueous solution, immediately after wetting the left cheek of each subject in each group. The subjects were left in a stable state for 10 minutes and then the skin temperature on the left cheek was measured again to confirm the persistence of the skin cooling effect. The average values of the subjects of the skin cooling effect of the composition of Example 1 and the comparative example are shown in Table 2 and graphically shown in Fig.
