Description

Detailed Description of the Invention (a) Industrial Application Field This invention relates to an ointment containing insecticidal and repellent ingredients used to protect living things from damage caused by sanitary pests, flying pests, ectoparasites, etc., and a method for producing the same. It is related to.

(B) Prior Art Conventionally, agents containing insecticidal and insect repellent ingredients have been used in the form of aerosols, emulsions, oils, powders, and granules.

(C) Problems to be Solved The above-mentioned agents containing insecticidal and repellent ingredients have a problem with their dosage form, and their insecticidal and repellent effects do not last long. It falls off from the target object, that is, the creature or the gauge, in a very short period of time. Especially outdoors/
The duration in livestock houses, poultry houses, etc. is short.

For this reason, drugs must be used frequently and in large quantities. This is not desirable not only in terms of labor and economy but also in terms of environmental pollution.

An object of the present invention is to provide an ointment containing an insecticidal and repellent ingredient that maintains its insecticidal and repellent effect without falling off the object for a long period of time, and a method for producing the ointment.

(d) Means for Solving the Problems This invention provides pyrethroid, organophosphorus, carbamate, diphenyl ether and other natural/synthetic insecticidal ingredients, insect repellent ingredients such as DEET (diethyltoluamide), and the like. and a potent enhancing synergist,
The present invention relates to an ointment containing an insecticidal and repellent ingredient, which is characterized by the following.

This invention also provides a combination of pyrethroid, organophosphorus, carbamate, diphenyl ether, and other natural/synthetic insecticidal ingredients, insect repellent ingredients such as DEET (diethyltoluamide), and synergists that enhance their efficacy. The present invention relates to a method for producing an ointment containing an insecticidal and insect repellent component, which is characterized in that solid fat, liquid fat, and mineral fine powder or diatomaceous earth are mixed into the ointment.

(e) Effect First, the effects of each component will be explained.

Pyrethroids act on nerve axons, organophosphates and carbamates inhibit cholinesterase, and diphenyl ethers act as IGR-like substances. These insecticidal ingredients are used as insecticides for general human epidemic prevention and animal epidemic prevention.

Insect repellent ingredients such as DEET act as repellents for biting insects.

Solid fats, liquid fats, and mineral fines or diatoms are the ingredients that form the base of ointments.

By mixing the above-mentioned insecticidal and repellent components with these components in appropriate proportions, an ointment with excellent spreadability that can be applied uniformly can be obtained.

As for the application method, the ointment may be applied by lightly touching the object with fingertips, a brush, a roller, a tube, etc. Since it is an ointment, it adheres to the target object for a long period of time and maintains its insecticidal and repellent effect.

(F) Examples Three examples (1st to 3rd examples) and the test results conducted using the first example will be described below, but it should not be limited to only those examples. Not even.

The proportions of each component to be mixed are: 0.1 to 1 part by weight of the insecticidal and insect repellent component, 20 to 65 parts by weight of solid oil, 20 to 50 parts by weight of liquid oil, and 5 to 15 parts by weight of mineral fine powder or diatom. preferable. If the ratio of solid oil to liquid oil, mineral fine powder, etc. is higher than this, the ointment will become hard and have poor spreadability, making it difficult to apply uniformly. Furthermore, if the proportion of solid fats and oils is less than this, it will be difficult to keep the solid fats and oils attached to the object for a long period of time.

Solid fats and oils refer to animal and plant mineral fats and oils that are solid at room temperature and are used as fixing agents. Refined lanolin, beef tallow, palm oil, soft coconut oil, soft whale oil, etc.

Liquid fats and oils are animal and plant mineral fats and oils that are liquid at room temperature, and are used as hardness and spreadability modifiers. These include olive oil, castor oil, cottonseed oil, soybean oil, and corn water.

Examples of fine mineral powders include white carbon, talc, clay, and bentonite.

The mixture of each component described above is heated to about 60°C to melt it,
By thoroughly stirring the mixture, making it into starch syrup, and cooling it, an ointment containing an insecticidal and repellent component according to the present invention can be obtained.

(First Example) 1 part by weight of an insecticidal insect repellent ingredient, 64 parts by weight of purified lanolin, 25 parts by weight of olive oil, and 10 parts by weight of white carbon are mixed while heating to approximately 60°C, made into a uniform syrup-like shape, and then cooled. do.

(Second Example) Using 1 part by weight of an insecticidal and repellent ingredient, 59 parts by weight of purified lanolin, 33 parts by weight of olive oil, and parts by weight of white kamphu,
A formulation is prepared in the same manner as in the first example.

(Third Example) A formulation is prepared in the same manner as in Example 1 using 1 part by weight of an insecticidal and repellent ingredient, 63 parts by weight of purified lanolin, 30 parts by weight of olive oil, and 6 parts by weight of white carbon.

Table 1 shows the physical property values of the first to third examples.

Spreadability was measured using a spread meter, and consistency was measured using a penetrometer at 25°C.

Table 2 (Test example) The experiment was conducted at a poultry farm A with approximately 10,000 chickens and a poultry farm B with about 50,000 chickens. A and B were divided into three areas, respectively: application of the ointment of Example 1, spraying of a 50-fold diluted solution of organophosphorus insecticide (Sumithion 10% emulsion), and no treatment, to eliminate the presence of mites in the cage and the excretory opening of the laying hens. Survival rates were investigated for 14 days. The test results for the cage are shown in Table 2, and the test results for the area around the general excreta of laying hens are shown in Table 3.

(g) Effects of the Invention As is clear from the above, the insecticidal and insect repellent-containing ointment according to the present invention does not fall off from the object for a long time, so the insecticidal and insect repellent effect lasts for a long time with one application.

Furthermore, there is almost no concern about environmental pollution compared to conventional agents containing insecticidal and repellent ingredients.

It also saves a lot of labor and is highly economical, making it extremely useful in industry.
