Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to an ointment containing an insecticidal and insect repellent component, which is used to protect organisms from damages such as sanitary pests, flying pests and ectoparasites, and a method for producing the same. It is about.

(B) Conventional technology Conventionally, the insecticidal and / or insecticidal component-containing agent has been used in the form of an aerosol, an emulsion, an oil, a powder, and a granule.

(C) Problems to be solved The above-mentioned insecticidal and insecticidal component-containing agents have problems in their dosage forms, and the insecticidal and insecticidal effect does not continue. It falls off from the object of interest, such as living things and gauges, in an extremely short time. Especially outdoors
The duration of livestock and poultry is short.

Because of this, frequent and large doses of drug must be used. This is not preferable not only in terms of labor and economy but also environmental pollution.

It is an object of the present invention to provide an insecticidal and insecticidal component-containing ointment having a long-lasting insecticidal and insecticidal effect without dropping from the target product and a method for producing the same.

(D) Means for Solving the Problems The present invention provides 0.1 to 1% by weight of pyrethroid type, organic phosphorus type, carbamate type, diphenyl ether type and other natural and synthetic insecticidal ingredients and insect repellent ingredients such as diet (diethyltoluamide). Parts, and a synergist for enhancing their efficacy, 20 to 65 parts by weight of solid oil and fat, 20 to 50 parts by weight of liquid oil and fat, and 5 to 15 parts by weight of mineral fine powder or diatomaceous earth were uniformly contained. The present invention relates to an ointment containing an insecticidal and insecticidal ingredient.

In addition, the present invention is a pyrethroid-based, organophosphorus-based, carbamate-based, diphenyl ether-based and other natural and synthetic insecticidal components and 0.1 to 1 part by weight of insect repellent components such as diet (diethyltoluamide), and enhance their efficacy. Synergist, solid oil 20 to 65 parts by weight, liquid oil 20 to 50 parts by weight, and mineral fine powder or diatomaceous earth 5 to 15 parts by weight,
The present invention relates to a method for producing an ointment containing an insecticidal and insecticidal ingredient, which comprises mixing, melting while heating, stirring well, forming a uniform starch syrup, and cooling.

(E) Action First, the action of each component will be described.

Pyrethroids act on nerve axons, organophosphorus and carbamate systems inhibit cholinesterase, and diphenyl ethers act as IGR-like substances. These insecticidal ingredients are used as insecticides for human general epidemics and animal pesticides.

Insect repellent components such as diet act as biting insect repellents.

Solid fats, liquid fats, and fine mineral powders or diatomaceous earth are components that form the base of ointments. By mixing the insecticidal and insect repellent components and these components in an appropriate ratio, an ointment having excellent spreadability that can be uniformly applied can be obtained.

As an application method, an ointment may be lightly contacted and attached to a target object with a fingertip, a brush, a roller, a tube or the like. Since it is an ointment, it adheres to the target substance for a long period of time and maintains the insecticidal and insecticidal effect.

(F) Examples The results of tests conducted using three examples (first to third examples) and the first example will be described later, but it should be noted that the examples should not be limited to these examples. There is no end.

The proportion of each component to be mixed is preferably 0.1 to 1 part by weight of the insecticidal and insect repellent component, 20 to 65 parts by weight of solid oil and fat, 20 to 50 parts by weight of liquid oil and fat, and 5 to 15 parts by weight of mineral fine powder or diatomaceous earth.
If the ratio of the solid oil / fat to the liquid oil / fat or the mineral fine powder is higher than this, the ointment becomes hard and the spreadability is poor and it becomes difficult to apply it uniformly. On the other hand, if the proportion of the solid fat is less than this, it becomes difficult to adhere the solid fat to the target substance for a long time.

Solid fats and oils are moving and plant mineral fats and oils that are solid at room temperature and are used as a fixing agent. Refined lanolin, tallow, palm oil, coconut oil ointment, whale oil soft, etc.

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

Mineral fine powders include white carbon, talc, clay and bentonite.

When the mixture of the above-mentioned components is heated to about 60 ° C., melted, stirred well, and cooled only in the form of starch syrup, the ointment containing the insecticidal and insecticidal ingredient according to the present invention can be obtained.

(First Example) 1 part by weight of insecticidal and insect repellent components, 64 parts by weight of purified lanolin, 25 parts by weight of olive oil, and 10 parts by weight of white carbon were added at about 60 ° C.
Mix while heating to form a uniform starch syrup and then cool.

(Second Example) Using 1 part by weight of an insecticidal and insecticidal component, 59 parts by weight of purified lanolin, 33 parts by weight of olive oil, and 7 parts by weight of white khan, a formulation is prepared in the same manner as in the first example.

(Third Example) Using 1 part by weight of insecticidal and insect repellent components, 63 parts by weight of purified lanolin, 30 parts by weight of olive oil, and 6 parts by weight of white carbon,
Formulation is carried out in the same manner as in Example 1.

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.

(Test Example) The test was conducted at about 10,000 poultry farms A and about 50,000 poultry farms B. Each of A and B was applied to the ointment of the first embodiment, sprayed with a 50-fold diluted organophosphorus insecticide (Sumithion 10% emulsion), and untreated into 3 sections, and each of the cages and the total excretion mouth of the laying hens were treated with Trisidiomyces Survival was investigated for 14 days. Table 2 shows the cage test results, and Table 3 shows the test results around the total excretory mouth of laying hens.
Shown in.

(G) Effect of the Invention As is apparent from the above, the insecticidal and insecticidal component-containing ointment according to the present invention does not fall off the target product for a long period of time, so that the insecticidal and insecticidal effect lasts for a long time with one application.

Moreover, there is almost no concern about environmental pollution as compared with conventional agents containing insecticidal and insect repellent components.

In addition, it is very labor-saving and highly economical, so it must be said that it has a very high utility value in industry.
