Abstract

A composition for preparing an emulsion or microemulsion, the composition including the following components (A) to (D):
component (A): an active ingredient having a solubility in water at 20° C. of 200 ppm or less; component (B): a water-insoluble solvent having no alcohol group; component (C): at least one nonionic surfactant selected from the group consisting of a polyoxyalkylene alkyl ether, a polyoxyalkylene alkenyl ether, a polyoxyalkylene alkyl amino ether, and a polyoxyalkylene alkenyl amino ether; and component (D): a monohydric alcohol having 8 to 12 carbon atoms.

First claim

The invention claimed is:

1. A composition for preparing an emulsion or microemulsion, the composition comprising the following components (A) to (D):
component (A): at least one selected from the group consisting of bifenthrin, etofenprox, fipronil, novaluron, hexaconazole, cyproconazole, propiconazole, tebuconazole, thiabendazole, fludioxonil, 3-iodo-2-propynyl butyl carbamate, 2-butyl-1,2-benzisothiazolin-3-one, 4,5-dichloro-2-octyl-4-isothiazolin-3-one, thiocyanatomethylthio benzothiazole, 2,3,5,6-tetrachloro-4-sulfonylmethylpyridine, diuron and cybutryne;
component (B): a water-insoluble solvent having no alcohol group which is a reaction product of a styrene and a mixture of xylene and ethylbenzene, wherein the reaction product comprises 1-phenyl-1-xylyl ethane and phenyl ethyl phenyl ethane;
component (C): at least one nonionic surfactant selected from the group consisting of a polyoxyalkylene alkyl ether, a polyoxyalkylene alkenyl ether, a polyoxyalkylene alkyl amino ether, and a polyoxyalkylene alkenyl amino ether; and
component (D): a monohydric alcohol having 8 to 12 carbon atoms,
wherein the composition does not contain an anionic surfactant.

2. The composition for preparing an emulsion or microemulsion according to claim 1 , further comprising a component (E) which is water.

3. The composition for preparing an emulsion or microemulsion according to claim 2 , further comprising a component (F): a neonicotinoid-based insecticide,
wherein, an amount of the component (A), relative to the mass of the composition, is from 5 to 15% by mass, provided that the amount of the component (A), relative to the mass of the component (B), is equal to or less than 100% by mass,
an amount of the component (B), relative to the mass of the composition, is from 10 to 20% by mass,
an amount of the component (C), relative to the mass of the composition, is from 20 to 60% by mass,
an amount of the component (D), relative to the mass of the composition, is from 5 to 15% by mass,
an amount of the component (E), relative to the mass of the composition, is 10 to 30% by mass, and
an amount of the component (F), relative to the mass of the composition, is 0.1 to 5% by mass.

4. The composition for preparing an emulsion or microemulsion according to claim 3 , further comprising a component (G) which is a nonionic surfactant other than the component (C), and
wherein a total amount of the component (C) and the component (G), relative to the mass of the composition, is from 40 to 70% by mass.

5. The composition for preparing an emulsion or microemulsion according to claim 1 , wherein the component (D) is lauryl alcohol.

6. The composition for preparing an emulsion or microemulsion according to claim 3 , wherein the component (F) is acetamiprid.

7. A wood preservative comprising the composition for preparing an emulsion or microemulsion according to claim 1 .
