Description

Composition containing plant-extracted mixed oil as an active ingredient {Composition containing plant-extracted mixed oil as an active ingredient}

The present invention relates to a composition comprising, as an active ingredient, a plant-extracted mixed oil having antibacterial, antifungal and insecticidal effects.

Cultural properties can be divided into inorganic cultural properties and organic cultural properties in terms of material. Inorganic cultural assets are generally composed of metal, stone, glass, etc., and organic cultural assets are composed of wood, paper, and textiles. In the case of small cultural assets, a few materials are mixed, but in the case of large wooden buildings, it is common to mix various types of materials.

Factors that change or damage cultural properties are roughly divided into natural factors and artificial factors, and natural factors can be further divided into physical, chemical and biological factors. Usually, cultural properties are damaged due to the complex action of several factors rather than due to a single factor. However, in the case of organic cultural properties, in particular, it can be provided as a nutrient source for bacteria and insects, and it is almost impossible to recover the original form from damage caused by bacteria and insects, so it is important to prevent damage by biological factors.

In addition to inorganic materials, many of the cultural properties in Korea are made of organic materials that are vulnerable to the passage of time, such as wood and paper. Cultural properties exhibited and stored in indoor spaces such as museums can be maintained in a more stable state than organic cultural properties located outdoors in an environment optimized for conservation and management. However, since it is important to maintain the original form of cultural properties, and continuous management and prevention are required according to the characteristics of materials, methods for biological control are continuously being studied.

Methods for biological control include a low-oxygen treatment method using carbon dioxide or nitrogen as an inert gas, a temperature treatment method to control the temperature, and a gamma-ray treatment method. However, such technology has time and economic difficulties in continuous management, so it is managed using insect repellent and antibacterial products in the exhibition space and storage space.

One method that is widely used as a method of removing strains and insects currently inhabiting cultural properties is a fumigation method. Methyl bromide and ethylene oxide, which are fumigants, are very effective in controlling insects and bacteria, but use of methyl bromide was restricted due to pollution and harm to the human body. Currently, an alternative fumigation gas including ethylene oxide and carbon dioxide mixed gas is being used.

In exhibition and storage spaces such as museums, fumigation is carried out every year to prevent biological damage to cultural properties. The gas used for fumigation is an effective method with excellent diffusion and permeability, but the drug is in a gaseous state, so there is no residual, so the drug effect does not last for a long time after treatment and it is very harmful to the human body during treatment. Therefore, in addition to fumigation treatment or separately, it is necessary to prevent damage from insects and bacteria by using low-toxic and persistent insect-repellent products for regular maintenance and management of cultural properties.

On the other hand, paradichlorobenzene as an insect repellent and paraformaldehyde and thymol as an insect repellent have been used. Organic cultural properties have deteriorated naturally over a long period of time, and their materials are in a state of very weakening. Due to the nature of the material, discoloration and hydrolysis may occur depending on the conditions of the surrounding environment (light, temperature, humidity, dust, harmful gas, etc.), which may accelerate deterioration. You should select and use those that are not given.

Accordingly, the present applicant is a composition using plant extract oil, which is a natural material, as an active ingredient, and by mixing oregano oil, clove oil, and cinnamon oil in a specific ratio, the antibacterial, antifungal and insecticidal activity related to the biological control of cultural properties is excellent as well as excellent. As a result of research to develop a composition that can have material stability, the present invention has been reached.

Aspergillus niger, Penicillium chrysogenum, and Trichoderma viride were selected for fungi, and Bacillus subtillis, Escherichia coli, and Staphylococcus aureus were selected for bacteria. Each strain was purchased from the Cultural Heritage Prevention and Conservation Research Institute at the Korea University of Traditional Culture.

A bacterial suspension was prepared by adding mold or bacteria to sterile water and uniformly mixing using a vortex mixer. A medium was prepared in a Petri dish (Ø90×15 mm) and 100 μl of the bacterial suspension was plated. In this case, PDA (Potato Dextrose Agar) medium was used for mold, and NA (Nutrient Agar) medium was used for bacteria. A paper disc (Ø8 mm, Advantec Toyo Kaisha, Ltd., JPN) in which 50 μl of the experimental solution prepared according to Preparation Examples 1 to 5 was absorbed was placed on the medium on which the bacterial suspension was smeared and sealed with parafilm.

The prepared medium was placed in a microbial incubator at a temperature of 30±2℃ (WIG-155, DAIHAN Scientific Co., KOR) and cultured for 3-5 days for mold and 1-2 days for bacteria. Afterwards, the growth inhibition ring formed was measured by measuring the length (mm) from the edge of the paper disc, and the average value was recorded and graded, and this was converted into a score. The rating evaluation criteria are shown in Table 2 below.

Adults were used regardless of male and female in the case of weevils and weevils, and in the case of termites, worker ants were used.

Insecticidal activity evaluation was conducted by fumigation toxicity evaluation. The fumigation toxicity test container was manufactured by overlapping two Insect Breeding Square Dish (72×72×100 mm ^{3 ) with different hole positions (Cap, Bottom).} In the lower container, a paper disc into which 50 μl of the experimental solution prepared according to Preparation Examples 1 to 5 was absorbed was placed. After putting 25 insects in the upper container, it was sealed with parafilm. They were reared in a thermo-hygrostat with a temperature of 26±2℃ and a relative humidity of 60±5%, and the number of larvae was counted for each hour (1, 3, 12, 24, 36, 48 hours). The average mortality rate for each hour was calculated, and the final mortality rate was graded and converted into a score. The rating evaluation criteria are shown in Table 2 below.

For each metal specimen, a copper plate, silver plate, and iron plate purchased from KM Science is measured with a width of 20 mm, a length of 20 mm, and a height of 1 mm. It was prepared by cutting.

Material stability was evaluated by Oddy test. A 1L glass wide-mouth bottle was prepared as an airtight container, and the ratio of distilled water was 1:100 for the glass wide-mouth bottle so that the relative humidity inside the bottle was maintained at 100%. A vial bottle containing 5 ml of the test solution prepared according to Preparation Examples 1 to 3 and 5 and the specimens were placed and sealed. In addition, the test was conducted using the specimens not treated with the test solutions of Preparation Examples 1 to 3 and 5 as a control group. Thereafter, after 28 days in a hot air dryer (WOF-155, DAIHAN Scientific Co., KOR) set at a temperature of 60±2°C, specimens were collected and the material state was evaluated as follows.

Observation of surface conditions

The surface condition of the specimen was observed with the naked eye and a microscope. The state of the specimen before and after evaluation was photographed using a digital camera (PowerShot G16, Canon, JPN). In addition, using a stereo microscope (SMZ18, Nikon, JPN), the surface change at the same location was photographed at 30 magnification.

chromaticity change

The color change of the specimen was measured using a spectrophotometer (ColorMate, Scinco, KOR). The degree of change in chromaticity before and after evaluation was confirmed within the three-dimensional spatial coordinates of the CIE-L*a*b*-System. The color difference (ΔE) before (L ^* ₁ , a ^* ₁ , b ^* ₁ ) and after evaluation (L ^* ₂ , a ^* ₂ , b ^* ₂ ) was derived by Equation 1 below. The resulting values were recorded and graded. Evaluation criteria are shown in Table 4 below.
