PURPOSE: To obtain a composition of a biocide or an agrochemical material by simultaneously emulsifying an active material relatively insoluble to water such as the biocide or the agrochemical material in an specific ratio together with an aliphatic hydrocarbon, or a glyceride oil by an aqueous structural surfactant without using a environmentally harmful solvent. n CONSTITUTION: This composition of a biocide or an agrochemical material is obtained by simultaneously emulsifying an active material such as a selective herbicide, a wide spectrum herbicide, a defoliant, an insecticide, an acaricide, a molluscicide, a fungicide, a growth adjusting agent, etc., with an aliphatic hydrocarbon or a glyceride oil (especially, a glyceride of a paraffin oil and of a turpentine oil are preferable) by an aqueous structural surfactant (e.g. a cationic, an anionic, a nonionic and an amphoteric surfactant) and in this case, a weight ratio of the surfactant to the active material is made smaller than (20:1) in order to obtain a stable emulsion. n COPYRIGHT: (C)1992,JPO |
