Regarding the production of the Tsubame extract of the present invention, the extraction device, the extraction temperature and the time are not particularly limited, but the extraction device is a heating extractor, a high pressure heating extractor, a supercritical extraction device, a Soxhlet type extractor, an ultrasonic extraction. A device, a microwave extraction device, etc. can be used. The temperature is generally -4 ° C to 180 ° C,
It is preferably room temperature to 120 ° C. The time is generally 1 minute to 120 hours, preferably 1 to 8 hours. The water to be used is 1 to 10000 times, preferably 10 to 1000 times, the dry weight of the swallow.

After the extraction, water is removed from the extract to obtain the swallow extract of the present invention. Water can be removed by using means such as vacuum concentration, freeze-drying, and atomization drying. It has been confirmed that the obtained Tsubame extract of the present invention is a white to yellowish white to brown crystalline powder and powder, and contains saccharides and proteins. It has also been confirmed to contain sialic acid.

As will be apparent from the examples described below, the Tsubame extract of the present invention has cosmetic and facial effects and has extremely high safety, and is therefore useful as a cosmetic.

【Example】

(1) Production Example of Tsubame Extract of the Present Invention 40 g of dried tsubame extract was finely cut into 1000 m of distilled water.
It was heated to reflux for 2 hours. When warm, it was filtered and the residue was similarly extracted. The extracts were combined, concentrated under reduced pressure, and the resulting concentrate was freeze-dried to yield a swallow extract 3.6.
g was obtained. The extract was a white to pale yellow to brown crystalline powder and powder.

(2) Formation of a film of the Tsubame extract of the present invention A 0.1, 0.5 and 1.0% aqueous solution of the Tsubaki extract of the present invention was prepared, and one drop of each concentration of the aqueous solution was placed on a glass plate. It was applied to a diameter of 2 to 3 cm and dried at room temperature. as a result,
Each of the 1.0 to 0.1% aqueous solutions formed a thin film on the glass plate.

(3) Beauty and facial effects of the Tsubame extract of the present invention A 0.5% aqueous solution of the Tsubame extract of the present invention was prepared and used as a test sample. 5 adult males and 10 females (20-45
, The test sample was applied to the face once a day for 3 days. As the evaluation items common to both men and women, the criteria for evaluation of moist feeling and smoothness of skin after use, effective, unchanged, and rough or rough, are used. , Got better,
A self-evaluation was made by adding a criterion consisting of three points: unchanged and worse.

The results are shown in Tables 1 to 3 below.

Table 1 Moisture Feeling Male Female Effect 3 7 No change 2 3 Crowded 0 0 Table 2 Smooth skin Male Female Effect 4 8 No change 1 2 Rough 0 0 Table 3 Makeup ladies improved 8 No change 2 Bad 0

When the Tsubame extract of the present invention was applied, many test subjects were found to have an effect on the smoothness of the skin and the paste of makeup, and a majority of the test subjects responded that the moist feeling was also effective. . From this result, the beauty and facial effects of the Tsubame extract were confirmed.

(4) Skin safety test of the tsubame extract of the present invention (4-1) Continuous skin irritation test in guinea pigs Measurement of Hartley male guinea pigs weighing about 260 to 290 g The 1% and 3.0% aqueous solutions were repeatedly applied once a day for 14 days, and the presence or absence of irritation to the skin was confirmed. As a result, during the administration period of 2 weeks, no irritation such as redness and edema of the skin was observed in the 0.1% and 3.0% application groups of the tsubame extract, and the skin irritation of the tsubaki extract was observed. It became clear that there was no.

(4-2) Skin sensitization test in guinea pigs Using a Hartley male guinea pig, according to a conventional method, the sensitization property of the swallow extract was maximized.
n) The test was conducted. In all cases of the primary sensitization, the secondary sensitization, and the induction, the 3% aqueous solution of the pit extract was used. As a result, no skin reaction was observed in the Tsubame extract sensitized group, and it was revealed that the Tsubaki extract was negative in skin sensitization.

(5) Production of Cosmetics Incorporated with Tsubame Extract The cosmetics containing the Tsubame extract of the present invention are not limited to the following Examples, but the present invention will be specifically described. In order to do so, some examples will be shown.

(5-1) Using Japanese Pharmacopoeia hydrophilic ointment as a base, about 10 g of this base and 1 g of the swallow extract obtained in this Example (1) were sufficiently kneaded, and then the remaining amount The base was added and kneaded so that the whole quality was uniform and the total amount was 100 g to obtain an ointment containing 1% by weight of the Tsubaki extract.

(5-2) 3 g of glycerin monostearate was heated and dissolved in a water bath, and heated glycerin 2
A lotion was prepared by adding 5 g of methyl cellulose, 1 g of methyl cellulose and 64 g of purified water obtained by dissolving 1 g of the tsubame extract obtained in Example (1), and stirring the mixture sufficiently to make the whole quality uniform.

[0022]

Industrial Applicability As described above, according to the present invention, the swallow extract has excellent cosmetic and facial effects and high safety, and thus is effective as a cosmetic and can be incorporated into cosmetics. Tsubame extract was provided.
