Hereinafter, the configuration of the wild animal repellent composition according to an embodiment of the present invention will be described.

The wild animal repellent composition according to an embodiment of the present invention may include a vegetable essential oil including at least one of an alcohol base, clove essential oil, cinnamon essential oil, and citronella essential oil, and a viscosity reducing agent.

The present invention may include an alcohol base. Alcohol bases can be used for rapid volatility of the repellent composition. Through the rapid volatilization of the repellent composition, it is possible to minimize coloration, contamination, droplets, and contamination of the surrounding environment around the injection hole. According to an embodiment of the present invention, the alcohol base is preferably an ethanol base. The alcohol base may comprise at least 75% by weight based on the total weight of the composition. Since the repellent composition according to the present invention does not use a surfactant and uses an ethanol base, it is possible to prevent contamination or clogging of the discharge port of the injection device due to an increase in viscosity. By using ethanol as the main base, it is possible to solve the problem that the conventional liquid repellent is composed of 100% extract, and the unit cost is high but the diffusion efficiency is low.

The present invention may include vegetable essential oils. The vegetable essential oil may include plant-derived essential oil having an effect of combating wild animals and pests. The repellent composition according to an embodiment of the present invention may include at least one of clove essential oil, cinnamon essential oil, and citronella essential oil as vegetable essential oil. The main effects of vegetable essential oils will be described in detail below.

The present invention may include a viscosity reducing agent. The viscosity reducing agent may be dipropylene glycol. The viscosity reducing agent may serve as an adjuvant to help dissolve the active ingredients of the repellent composition. It can also play a role of stabilizing by dissolving emulsifying ingredients. According to an embodiment of the present invention, the viscosity reducing agent is preferably 4 to 5% by weight, and particularly preferably 5% by weight, based on the total weight of the composition. Viscosity reducing agent can reduce the viscosity of the repellent composition to prevent problems such as coloring contamination around the injection port, dropping, splashing when used in an automatic spraying machine or a spray type spraying device.

Vegetable essential oils and extracts of the present invention may be various extraction methods such as extraction methods using alcohols such as ethanol, hot water extraction methods, etc., which are conventional extraction methods, and since the extraction method is a known technique, specific methods will be omitted. To

Hereinafter, the effects of the main active ingredients of the present invention will be described.

Clove essential oil contains eugenol, a volatile component with strong irritation, and can exhibit a repelling effect by stimulating the sense of smell and taste. In addition, it has the advantage of strong initial irritation rather than repellent effect due to contact or ingestion, and has excellent antibacterial and antifungal effects and excellent repellent effect against pests, preventing external contamination or decay of the composition, thereby reducing the effectiveness of the repellent composition. Can be suppressed. The clove essential oil may be included in 2 to 10% by weight based on the total weight of the composition.

Cinnamon essential oil contains cinnamon aldehyde and cinnamic acid as the main active ingredients, and can exhibit a repelling effect due to an olfactory repellent effect due to an irritating volatile scent and an eye mucosa irritation effect. It is also known to be excellent in controlling harmful pests such as mites. The cinnamon essential oil may be included in 2 to 10% by weight based on the total weight of the composition.

Citronella essential oil can be extracted from the leaves of Gumuncho, known as mosquito repelling grass. The fresh and stimulating scent of grass leaves has excellent antibacterial and antifungal effects and repellent effects against pests. Especially, it has excellent efficacy against flies and mosquitoes. In addition, it is harmless enough to be classified as a non-toxic substance that is not subject to harmful/harmless regulation by the US Environmental Protection Agency (EPA). The citronella essential oil may be included in an amount of 0.1 to 1% by weight based on the total weight of the composition. At this time, if the citronella essential oil is mixed in excess of 1% by weight, the fragrance of other active ingredients is reduced, thereby reducing the effect of repelling wild animals, so it is preferable to use less than 1% by weight.

Indole is solid at room temperature, occurs naturally in human feces and has a strong stool odor. This strong odor stimulates the sense of smell and taste, and the effect of stimulating the evasion instinct against predators above the ecosystem can exhibit a combating effect. In addition, there is an advantage in that initial stimulation is strong rather than repellent effect by contact or ingestion. The indole may be included in an amount of 0.1 to 1% by weight based on the total weight of the composition. At this time, if less than 0.1% by weight of indole is used, there is a problem that the combating effect on wild animals is lowered, and if more than 1% by weight is used, the aroma of other active ingredients is reduced and the composition according to the external environment such as sunlight and temperature. There is a disadvantage that the possibility of discoloration of the whole becomes large.

Menthol can exhibit a repelling effect due to a strong irritating volatile scent and a repelling effect due to an eye mucosa irritant effect. In addition, it has the advantage of strong initial irritation rather than repellent effect due to contact or ingestion, and has excellent antibacterial and antifungal effects and excellent repellent effect against pests, preventing external contamination or decay of the composition, thereby reducing the effect of the repellent composition. Can be suppressed. The menthol may be included in an amount of 0.1 to 1% by weight based on the total weight of the composition.

Capsaicin extract is a red pepper extract, a dark red liquid with a characteristic tangy red pepper scent. Capsaicin is used as a pesticide registered with the US Environmental Protection Agency (EPA). Capsaicin extract can exhibit a wild animal repelling effect by stimulating the sense of smell, respiratory tract, and eyes due to strong fragrance and contact stimulation. The capsaicin extract may be included in an amount of 0.1 to 1% by weight based on the total weight of the composition. At this time, if the capsaicin extract is used in an amount of 1% by weight or more, it is preferable to use less than 1% by weight, since it may cause a solubility problem on the ethanol base and irritate the user's eyes, respiratory tract, skin, etc. to make handling difficult.

Methyl salicylate is a raw material that has a strong scent such as a parse odor. It makes you feel the stimulating effect of the sense of smell and can exterminate the effect. In addition, it has the advantage of strong initial stimulation rather than repelling effect by contact or ingestion. Methyl salicylate may be included in 2 to 5% by weight based on the total weight of the composition.

Acetic acid is the main active ingredient in vinegar and has a characteristic sour and spicy odor. Acetic acid is classified as a mild acid, but it can irritate the nasal cavity or mucous membranes of the eye due to its strong volatile fragrance. The acetic acid may be included in 1 to 2% by weight based on the total weight of the composition.

Green leaf aldehyde is a component contained in substances secreted by stinkweed to protect itself from natural enemies, and plays a role in killing or repelling ants in particular. The green leaf aldehyde may be included in an amount of 0.05 to 0.1% by weight based on the total weight of the composition. At this time, when using more than 0.1% by weight of green leaf aldehyde, it is preferable to use less than 0.1% by weight because there is a disadvantage of reducing the odor of other active ingredients.

In the present invention, by using a combination of plant essential oils and other effective chemicals effective in combating wild animals, it is possible to expect a maximum repelling effect against various harmful factors such as various species of wild animals and pests. The repellent effect can be sustained by mixing the alcohol base with highly volatile repellent ingredients so that the entire contents volatilize quickly and the odor remains. In addition, it minimizes concerns about environmental damage to residual raw materials, and at the same time, it is a low-viscosity fluid liquid that can be easily grafted into an automatic sprayer or spray.

The present invention will be described in more detail through the following examples. These examples are only for describing the present invention in more detail, and it will be apparent to those of ordinary skill in the art that the scope of the present invention is not limited by these examples according to the gist of the present invention. .

[Example] Preparation of wild animal repellent composition

While stirring the ethanol base at a speed of 300 rpm at room temperature, each raw material was added as shown in [Table 1] and stirred for about 10 minutes to prepare a wild animal repellent composition.

Raw material name Example 1 Example 2 Example 3 Example 4 ethanol 74.90 74.90 81.90 82.00 Clove essential oil 10.00 2.00 2.00 2.00 Cinnamon refinery 2.00 10.00 2.00 2.00 Citronella Refinery 1.00 1.00 1.00 1.00 Dipropylene glycol 5.00 5.00 5.00 5.00 Indole 0.40 0.40 0.40 0.40 menthol 1.00 1.00 1.00 1.00 Methyl salicylate 4.55 4.55 4.55 4.55 Acetic acid 1.00 1.00 2.00 1.00 Green leaf aldehyde 0.05 0.05 0.05 0.05 Capsaicin extract 0.10 0.10 0.10 1.00 100.00 100.00 100.00 100.00

[Experimental Example 1] Evaluation of solubility of active ingredients

After preparing the composition as in Examples 1 to 4, turbidity and precipitation over time were confirmed.

The results are shown in Fig. 1, and in the case of Example 4, it was confirmed that turbidity and suspended precipitates occurred in the liquid phase immediately. This is due to the dissolution stability of the oleoresin-type capsaicin extract, and when applied to an automatic sprayer or spray, there is a concern that a clogging phenomenon may occur at the discharge port, so the capsaicin content is preferably limited to a level of less than 1% by weight.

[Experimental Example 2] Evaluation of the efficacy of repelling wild boars

With the cooperation of wild boar breeding farmers, an automatic spraying device was installed on the floor at 2m intervals around the residual feed container, and 2mm of the repellent composition was sprayed on the opposite side of the feed container every 20 minutes to observe changes in the amount and behavior of wild boars. Since the scent of the feed is strong, the spraying position was set at a distance of 2 meters based on the leftover bucket, and in consideration of the fact that reverberation may be mixed even after washing, the spraying time of each example was adjusted for 4 weeks, every Monday morning (10 am to 11 pm). There was enough spacing in a way that only works.

Feed amount: 10kg Example 1 Example 2 Example 3 Feed residual amount (kg) 9.8 9.4 10

As shown in the results of [Table 2], in the case of Example 3, it was confirmed that the wild boars did not consume feed at all. In the case of Example 3, in which the initial diffusion stimulation by acetic acid is expected to be the strongest, it is considered that economical effects can be expected as it shows the most effective repelling effect while lowering the content of expensive vegetable essential oils.

[Experimental Example 3] Confirmation of the effect of preventing damage to farmhouses

The Gijang area of Busan is a place that suffers damage every year due to the appearance of wild boars during the winter when feeding of wild animals is difficult. Among them, the repelling effect was verified with the help of sweet potato cultivation farmers, which are frequently damaged. A sprayer was installed at a height of about 50cm from the ground along the fence of the target area as shown in FIG. 2, and the composition of Example 3 was sprayed for 4 weeks, every Monday morning (10 a.m. to 11 p.m.) to observe the trend of damage occurrence. .

As a result, in the light of the fact that no damage to the farmhouse occurred during the application period of the repellent composition of the present invention, and damage to nearby farmhouses did not occur within the period, it is expected that the effect of repelling wild animals by the olfactory stimulating function due to gas diffusion was certainly expected. It is believed to be possible.
