Description

  TECHNICAL FIELD The present invention relates to a skin mite control agent used for killing skin mites and a skin external preparation containing a skin mite control agent.

  In recent years, skin mites such as Demodex Brevis and Demodex Folicolorum have been discovered. These skin mites live under the skin such as sebaceous glands and hair roots and absorb nutrients such as sebum and damage cells, causing acne, rough skin, reduced skin metabolic function, and hair loss. For this reason, the removal of skin mites is one of the effective means for healing skin diseases and preventing hair loss.

Moon peach is said to be a substance that can control skin ticks. This moon peach has the scientific name Alpinia zerumbet cv. It is a plant belonging to the genus Glyceraceae, which is a Variegata, and is distributed in subtropical climate areas such as the Ryukyu Islands. It has been known for a long time that moon peach has an insecticidal action and an antibacterial action. For this reason, it is used, for example, for wrapping and storing foodstuffs. When moon peach is used to control skin mites, essential oil is obtained from dried rhizome rhizomes, and this moon peach essential oil is blended into hair shampoos and hair tonics. And, by using these to wash and style the hair, insects and insects that inhabit the scalp are killed and exterminated.

  Skin mites were collected by collecting a certain amount of skin sebum from the skin nose of each subject using the subjects as samples. The skin was sprayed with cypress water having a concentration of 0.1% by weight diluted in water, a safflower extract having a concentration of 0.01% by weight diluted in water, and a plant extract extract having a concentration of 0.001% by weight diluted in water. The time to mite death was measured. Sample A is a 30-year-old man, Sample B is a 35-year-old woman, Sample C is a 35-year-old man, Sample D is a 36-year-old man, and Sample E is a 39-year-old woman. Table 1 lists the time to death of all skin mites. “Leave” is the time when the image is left as it is.

  As is apparent from Table 1, it is possible to kill skin ticks by bringing the skin tick control agent of this Example into contact with skin ticks.

  Moreover, the skin mite control agent of Table 1 was impregnated to the tape, and it affixed on the skin of the sample AE mentioned above. The state of sticking was continued for 12 hours, 24 hours and 3 days, and the influence on the skin was examined. As a result, no skin diseases such as red spots and sores occurred in any specimen. Thereby, it was found that the above-mentioned skin mite control agent has low irritation to the skin and high safety. Therefore, even if used repeatedly, there is no induction of skin diseases such as rough skin.

  As in Example 1, skin mites were collected by collecting a certain amount of skin sebum from the skin nose of the specimen (subject). In this example, a compound extract obtained by mixing the cypress water, safflower extract and plant extract mixture used in Example 1, and 0.001% by weight of Umeodorum oil diluted in water with this compound extract were further blended. The sample was used as a sample. Then, these samples were sprayed on the collected skin mites and the time until the death of skin mites was measured. Sample F is a 30 year old male, Sample G is a 31 year old female, Sample H is a 35 year old male, Sample I is a 36 year old male, and Sample J is a 39 year old female. Table 2 lists the time to death of all skin mites.

  As is clear from Table 2, in the case of a composite extract in which cypress water, safflower extract and a plant extract mixture are mixed, it takes a certain amount of time to control skin mites. In some cases, it is possible to shorten the time for skin tick control. Thereby, it turns out that skin mite control is performed more effectively by the blending of Umuro buckthorn oil.

  Moreover, the skin mite control agent of Table 2 was impregnated in the tape, and it affixed on the skin of the test substance FJ mentioned above. The state of sticking was continued for 12 hours, 24 hours, and 3 days, and the influence on the skin was examined. As a result, no skin diseases such as red spots and sores occurred in any specimen. Thereby, it was found that the above-mentioned skin mite control agent has low irritation to the skin and high safety. Therefore, even if used repeatedly, there is no induction of skin diseases such as rough skin.

  As in Example 1, skin mites were collected by collecting a certain amount of skin sebum from the skin nose of the specimen (subject). Then, the time until the skin mite was killed was measured by spraying it on the collected skin mite with a concentration of 0.001% by weight diluted in water. Sample K is a 30-year-old man, Sample L is a 35-year-old woman, Sample M is a 35-year-old man, Sample N is a 36-year-old man, and Sample O is a 39-year-old woman. Table 3 lists the time to death of all skin mites.

  As is clear from Table 3, it is possible to effectively remove skin ticks even with a single Umellium oil.

  In addition, the tape was impregnated with the above-described concentration of Umeuro dome oil and adhered to the skin of the specimens K to O described above. The state of sticking was continued for 12 hours, 24 hours, and 3 days, and the influence on the skin was examined. As a result, no skin diseases such as red spots and sores occurred in any specimen. As a result, the sea buckthorn oil is less irritating to the skin, has a high level of safety, and does not induce skin diseases such as rough skin even after repeated use.

  Also in this example, skin mites were collected by collecting a certain amount of skin sebum from the skin nose of the specimen (subject). And the number of skin mites is counted, and the mixture ratio of the cypress water, safflower extract, sea buckthorn oil and the plant extract extract used in the skin lotion shown in Formulation Example 2 above for the collected skin mites This was diluted with water to obtain a sample of this example. This sample was sprayed on skin mites and the time until the death of skin mites was measured. Sample P is a 30-year-old man, Sample R is a 31-year-old woman, Sample S is a 34-year-old man, Sample T is a 25-year-old man, and Sample U is a 20-year-old woman. Table 4 lists the time to death of all skin mites. “Leave” is the time when the image is left as it is. The samples T and U were carried out without counting the number of collected skin mites.

  Further, this sample was impregnated into a tape and adhered to the skin of the specimens P to U described above. The state of sticking was continued for 12 hours, 24 hours, and 3 days, and the influence on the skin was examined. As a result, no skin diseases such as red spots and sores occurred in any specimen. As a result, the irritation to the skin is small and the safety is high. Therefore, even when used repeatedly, skin diseases such as rough skin are not induced.

  For the specimens P, R, and S in Example 4, the sample of Example 4 was applied to the skin for 1 month, and the number of skin mites living in the skin nose groove was counted after 1 month. As a result, the sample P decreased from 12 to 0, the sample R decreased from 8 to 1, and the sample S decreased from 13 to 0.

  The cosmetic cream of Formulation Example 1, the lotion of Formulation Example 2, and the shampoo of Formulation Example 3 were allowed to be continuously used by 3 specimens (subjects) for one month, and the number of skin mites before and after use was determined. I counted. A skin tick confirms the number of individuals in the sample by collecting sebum from the skin of the specimen. Sample V is a 36 year old male, Sample W is a 39 year old female, and Sample X is a 35 year old female. Table 5 shows this result, showing that there is no or a drastic decrease in skin mites after one month of use, and this is effective in controlling skin mites.

  Since the skin mite control agent of the present invention kills skin mites, it can prevent acne, rough skin, reduced skin metabolic function, and hair loss. Since the skin external preparation of the present invention contains a skin mite control agent, it can control skin mites in addition to the original effects of the external preparation.
