Abstract

The invention discloses an emulsifier, a dispersible oil suspension agent containing the same and a preparation method of the dispersible oil suspension agent, and belongs to the field of pesticide preparation processing. The emulsifier comprises the following components in parts by weight: 10-50 parts of anion modified polyether, 30-80 parts of castor oil polyoxyethylene ether, 20-70 parts of sorbitan fatty acid ester, and 0-50 parts of calcium dodecyl benzene sulfonate. The emulsifier is excellent in emulsifying effect, strong in emulsion stability and favorable for long-term storage.

Description

technical field [0001] The invention relates to the field of pesticide preparation processing, in particular to an emulsifier, a dispersible oil suspension containing the emulsifier and a preparation method thereof. Background technique [0002] Dispersible oil suspension concentrate is a kind of pesticide dosage form that disperses the active ingredient in solid particles in non-aqueous medium to form a stable suspension preparation. It is generally diluted with water before use. It has achieved rapid development in China in the past ten years. From 1 registered product to nearly 400 registered products in 2015, the number of product registrations has increased by more than 100 times. Dispersible oil suspension formulations generally consist of active ingredients, emulsifiers, dispersants, thickeners, carriers and other basic components. Some formulations also need to add stabilizers or pH regulators according to actual conditions. [0003] Commonly used carriers for proce...
