Abstract

PURPOSE:An agricultural chemical composition that is made by solubilizing or emulsifying ingredients of agricultural chemicals insoluble or hard soluble in water into a polyhydroxy compound or its aqueous solution in the presence of protein, protein hydrolyzates or surface active agents, thus being insoluble or hard soluble in water and showing high stability for a long period of time. CONSTITUTION:In the presence of protein such as sodium casein or soybean protein, protein hydrolyzate, a surface active agent such as soap, N-acylamino acid salt, polyoxyethylene alkyl ether, agricultural chemicals insoluble or hard soluble in water are solubilized or emulsified into a polyhydroxy compound such as glycerol or propylene glycol or its aqueous solution to give the objective composition. The agricultural chemical is solubilized up to 5-6 times the amount of the polyhydroxy compound or its aqueous solution. Even when no surface active reagent is used, this composition shows high solubilization effect.

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an agrochemical composition, particularly an agrochemical composition in which a water-insoluble or poorly soluble agrochemical is solubilized or emulsified.

The amount of the above-mentioned agricultural chemical component used varies depending on the purpose and use, and in the composition of the present invention, the amount of the solubilized substance (agricultural chemical component) can be up to 5 to 6 times the weight of the polyhydroxy compound solution or its aqueous solution. Since it can be dissolved, it can be adjusted within this range depending on the purpose. However, as the amount of the substance to be solubilized increases, the viscosity of the system increases, becoming jelly-like and losing fluidity.

The composition of the present invention can be obtained by adding proteins, protein decomposition products, surfactants, etc. to a polyhydroxy compound or an aqueous solution thereof, and dropping the agricultural chemical component or the agricultural chemical component dissolved in an organic solvent thereto while stirring. The compound is uniformly dispersed and solubilized in a solution containing a hydroxy compound to obtain a composition.

Stirring methods include heating to lower the viscosity of the system and using a high-speed stirrer such as a homomixer, and low-speed stirring at room temperature using various stirring blades used for stirring highly viscous solutions.

The solubilized system varies from colorless and transparent to opalescent and opaque depending on the properties of the substance to be solubilized, the polyhydroxy compound used, and the type of protein, but the common thing is that water is added to the solubilized system. and a stable q-order emulsion can be obtained.
