+: Mold on the walls or lids within 4 weeks

++ Odor in 4 weeks and mildew on specimen surface

+++: Odor and mold on the entire surface of the specimen within 4 weeks

(Skin patch test)

In the past, skin patch tests were conducted on 20 women in their 20s who did not show hypersensitivity to skin irritation and have no skin disease or skin allergy. Lactic acid at a concentration of 5%, a skin irritant, was used as a comparative example, and the inside of Habak, a test site, was wiped with 70% ethanol and dried. Next, the specimen in the same conditions as the antiseptic test was sealed and patched to the test site. After patching for 24 hours and removing it, the test site was marked with a pen, and after 1 hour and 24 hours, the test site was observed using a magnifying glass (8MC-150, DAZOR, United States of America) to observe erythema and edema. It was. Skin response was determined according to the regulations of the International Contact Dermaitis Research Group (ICDRG), and the average skin response rate was calculated according to Equation 3. The evaluation criteria are as follows.

-: No response

±: faint erythema

+: Boundary but weak erythema, edema and papules

++: pronounced erythema, papules and vesicles

+++: Severe erythema and alveolar, skin formation

(Example 1)

First, prepare 100g each of Goldamcho, Ginseng, Gosam and Roots of Roots and wash it to remove impurities, and then add 500g of distilled water for each medicine and heat it for 3 ~ 4 hours using a medicine bath (OC-8300R, Health Cooking Hitech, Korea). Extracted. The extract obtained by repeating this process three times was filtered using a gauze (Gaze), and then the filtrate was concentrated. And each prepared extract was mixed, but the functional extract was prepared by mixing at the ratio of 53% by weight of the oleander extract, horseradish extract 15% by weight, red ginseng extract 25% by weight, frogs extract 7% by weight.

Next, a polyester meltblown nonwoven fabric coated with a water repellent agent containing a fluoroalkyl acrylate copolymer having a thickness of 1 mm was used as a water repellent layer, and the modified starch powder was applied to a thickness of 1 cm. After laminating a polypropylene spunbond nonwoven fabric having a thickness of 1 mm thereon as a protective layer, the water repellent layer and the protective layer were sewn to complete a diaper specimen. The functional extract prepared therein was applied and it was applied at 40 ° C. for about an hour. Drying completed the specimen. The physical properties of the finished specimens were measured and listed in Table 1 below.

(Example 2)

When preparing the functional extract in Example 1, the same method except that the functional extract was prepared by mixing in the ratio of 68% by weight, gingko biloba extract, 15% by weight, Red ginseng extract, 10% by weight, Frogrius extract, 7% by weight The specimen was completed. The physical properties of the finished specimens were measured and listed in Table 1 below.

(Example 3)

When preparing the functional extract in Example 1, the same method except that the functional extract was prepared by mixing at the ratio of 45% by weight of the extract of Gollidiots, 15% by weight of horseradish extract, 25% by weight of red ginseng extract, 15% by weight of the frog extract The specimen was completed. The physical properties of the finished specimens were measured and listed in Table 1 below.
