Description

[0001] Mosquito repellent compositions [

The present invention relates to a mosquito-repellent composition, and more particularly, to a mosquito-repellent composition which uses mugwort, cinnamon and citronella oil, which are harmless to humans and exhibit excellent repellent activity against mosquitoes, and raw materials extracted from phytoncide oil, The present invention relates to a mosquito-repellent composition which is good on skin through vegetable oils such as jojoba oil and functional jujube solution.

Mosquitoes cause people to lose their lives by interfering with sleep and obstructing sleeping activities, limiting outdoor activities, etc., as well as damaging directly or indirectly, as a pest that mediates various diseases such as malaria, encephalitis, yellow fever and dengue fever. Two thirds of the world's population is exposed to mosquito-borne diseases.

There are more than 3,000 species of mosquito species in the world, and there are about 500 kinds of tropical striped mosquitoes, about 300 kinds of mosquito mosquitoes and about 350 kinds of mosquito mosquitoes. There are 20 tropical mosquito species, 18 mosquito species, and 7 mosquito species.

In addition, the blood vomiting of the mosquito acts as a source of stress such as disturbance of sleeping and restriction of outdoor activities, and it is a pest which causes serious damage directly or indirectly.

Among the mosquitoes known in Korea, Chinese mosquito wing mosquitoes are malaria and inland mosquito onchocerciasis, onchocerciasis in the southern sea area of Togo forest, red mosquitoes mediate Japanese encephalitis, and other red mosquitoes House mosquitoes have recently been infested in the apartment complex, causing problems with blood collection.

Conventionally, in order to control mosquitoes, chemical control with insecticide was mainly used. However, use of chemical synthetic insecticide caused side effects such as drug resistance, killing of useful creatures, toxicity to human body, residuals and various environmental pollution.

Various solutions have been studied to protect the human body from the attack of these mosquitoes. Among them, there is no effect of killing the mosquitoes in the representative method. However, the mosquito contains a substance that the mosquitoes dislike, .

However, considering that the repellent is directly used in the human body, it has a function of controlling irritation to the senses of the mosquito. Therefore, the requirements of the chemical components such as the effect on the human and the ecosystem and the minimization of side effects are very difficult.

Therefore, it is urgently required to develop alternative medicine and control method of pesticide that can minimize the impact on ecosystem and effectively protect human from mosquito.

DEET (N, N-diethyl-m-toluamide or N, N-diethyl-3-methylbenzamide) is the most widely used synthetic herbicide, Although it has an avoidance effect, it has an unpleasant and irritating odor. Due to the high penetration of skin, pregnant women, children, hypotensive patients and sensitive skin patients are limited in their use. Even in healthy adults, And it has a problem that it reacts with some plastics or synthetic rubber to cause discoloration or the like.

Accordingly, studies on repellents capable of replacing DEET have been actively carried out. Recently, there have been a lot of researches on repellents that can replace DEET. In recent years, research has been conducted on natural products such as Thymus quinquecostatus, Carvacrol, Thymol, Although a repellent agent containing a substance has been proposed, the effectiveness of the mosquito repellent agent has been greatly reduced compared to DEET, and the practicality has been questioned. Also, since the duration of the repellent effect after spraying and application is short, it has been troublesome to treat it several times.

A repellent developed as a new concept as an alternative medicine for insecticides is a natural substance which inhibits the behavior of a creature is used as a pest control and it is attracting attention because it can prevent insect-mediated diseases to humans and has no side effects such as environmental pollution .

However, repellents are difficult to meet because they must contain the function of controlling human insects' chemical senses, as well as their use. Essential requirements for repellents are that they are harmless to the human body, are not irritating to the skin, have no unpleasant odor, are chemically stable, and have no effect on the entire surface of the skin.

Especially, when sprayed on clothes, it has a temporary effect, but due to its strong volatility, the effect disappears after a certain period of time, and therefore, it requires economical and temporal loss to be periodically sprayed for continuous defense.

On the other hand, Artemisia Linne belonging to Asteraceae is reported to have 200 species in the northern hemisphere and 38 species in Korea, and it is reported that it contains various kinds of wormwood, wormwood, wormwood, yellow mugwort, Stems and petioles are medicinal, young leaves are edible, and ordinary leaves are used to make moxa. White hair is used to scrape and make ink, and it is also called Baekho, Seonae, or Baekho.

Mugwort is used as a hemostatic agent for nosebleeds and uterine bleeding in an oriental medicine. It is effective for digestion, lower abdomen labor, insect repellent and odor removal, and is effective for gastrointestinal diseases, constipation, neuralgia, cold disease, women's disease and asthma. come.

Artemisia princeps Pamp. Has been naturally grown in the Ganghwa region of Korea. The name of lepidoptera wormwood has been historically recorded as "lion flower buds" in the souvenirs of Ganghwa Dohbu, 'From the description of' lepidoptera '.

Mugwort not only contains nutrients of various pharmacologically useful ingredients, but also has a characteristic of chasing pests such as mosquitoes with its fragrance in addition to its fragrance ingredient.

Also, broilers are also called cinnamon, which is camphor plant and is dried only by removing the skin of cassia. In one room, the bark of a small branch is called a cinnamon or anchovy, and it is called a pale yellow tissue between the bark and the tree. Thus, the broiler, stew, cinnamon, and stomach are classified as herbal medicine. Biologically, the bark obtained from a plant having the scientific name of "Cinnamomum cassia" is called cinnamon.

It is known that broiler chicken is effective in relieving fatigue and strengthening eyesight by enhancing kidney function and liver function, and is effective in sedation of central nervous system, hypotensive effect, and improvement of adrenocortical function. In addition, it has been reported that there are many biological activities such as insecticidal and feeding inhibitory activity of flow-related materials, swelling inhibitory activity against rats, and fumigant activity against acorn geese worms.

Accordingly, the present inventors have made intensive studies to develop new mosquito repellents derived from natural products. As a result, the present inventors have completed the present invention based on the fact that some substances of vegetable ingredients are excellent in mosquito repellent effect.

It is known that broiler chicken is effective in relieving fatigue and strengthening eyesight by enhancing kidney function and liver function, and is effective in sedation of central nervous system, hypotensive effect, and improvement of adrenocortical function.

Citronella is 90 cm in length, thin and long, and adaptable enough to grow well everywhere. A oriental perennial plant, extracted from wild growing managrass in Sri Lanka. Indonesia It is cultivated in the tropical regions of Java Island, Vietnam and Africa, and is used in many countries because of its high directivity and medicinal value.

To extract Essential Oil from Citronella leaves, dried leaves rather than fresh leaves are extracted by steam distillation method. Especially, partially dried or completely dried Citronella pulp can be made into essential oil by steam distillation method, Used as a raw material for cosmetics.

In particular, Citronell has a fragrance that dislikes insects, so it completely blocks access to insects and mosquitoes, so it is also used as a pest control agent. Therefore, it is mainly used to prevent attack of pests such as balm mosquito on the skin. In addition, it is used as preservative, fungicide and deodorant. Besides, it has excellent sterilization effect and preservative function, and it has a function to stabilize the nerve, which is good for headache, migraine, neuralgia.

Phytoncide was first proposed in 1937 by Boris P. Tokin, a biochemist at the University of Leningrad in Russia (currently the University of Saint Petersburg). The word 'phyton' means 'plant' and 'cide' means 'kill'.

Until the beginning of the 20th century, it was thought that in order to treat pulmonary tuberculosis, it should be treated with good air in the forest. Because it believed that phytoncide, which leads to various antimicrobial substances coming from plants, enters the body and removes bad pathogens, pests and fungi. The major component of phytoncide is terpenes, which include terpenes, phenolic compounds, alkaloids, and glycosides.

Drinking phytoncide through the forest bath relieves the stress, strengthens the bowel and cardiopulmonary function, and sterilization also takes place. There is a movement to utilize the efficacy of phytoncide on various products. Phytoncide ingredients can be extracted in fragrance, or flowers and leaves of plants can be used for food. The unique phytoncide fragrance of the plant also makes it possible to store food for long periods

In addition, vegetable fats such as palm oil and jojoba oil, which are included in the mosquito-repellent composition of the present invention and which improve the skin of the human body, occupy 20 to 25 wt% and 5 wt%, respectively, based on the total weight of the mosquito- , Agar-agar agar-agar solution is 1 to 2% by weight based on the total weight.
