When we process microemulsion ME, sometimes the order and mode of feeding have a great influence on the final product appearance, quality, and stability of the microemulsion ME. Several processing methods for the following transfer are summarized very well. a bit!

Method a: Mix soluble and water emulsifiers with deionized water, or add some advanced alcohols to help dissolve, then add the oil-soluble pesticides to the water under intense stirring. Make a transparent o/w type. Microemulsion.

b method: the emulsifier and the pesticide original drug mixed to form a solution, you can add part of the agent, after the high-speed stirring in drops such as water, the formation of a transparent o / w microemulsion. Can also be the opposite of the water droplets into the oil to form w /o microemulsion. As for the formation of that kind of main water size and hydrophilicity.

Method c: After mixing pesticide, emulsifier and volume into oil phase, slowly add deionized water under stirring to form w/o type microemulsion. After stirring and heating, turn it quickly to turn into o/w microemulsion cooling. After that.

d method: if there are two different kinds of original drugs (such as one is water-soluble and one is oil-soluble), the water-soluble drug can be firstly formulated into an aqueous solution, and the low-HLB emulsification is added. The agent is then dripped into the oil phase solution under stirring to form a w/o emulsion, and the aqueous solution of the high HLB value emulsifier is smoothly mixed to form a w/o/w type microemulsion, and the general emulsifier dosage is 20%. about.

Pesticide microemulsion is a new formulation developed in recent years. The microemulsion is a thermodynamically stable system and has the advantages of good stability over time. The unique penetration and solubilization of the microemulsion system promotes the absorption of pesticides by plants and increases the availability of pesticides. Due to the significant reduction in the use of volatile organic solvents (VOCs), pesticide production reduces both environmental pollution and production costs.
