Embodiment Construction

[0020] The azadirachtin emulsifiable oil composition of the present invention and its preparation method are described in detail below in conjunction with specific examples.

[0021] Azadirachtin emulsifiable oil composition of the present invention is made up of azadirachtin, emulsifier, penetrating agent, stabilizer, antifreeze agent, cosolvent and solvent, and its preparation method is as follows:

[0022] Fully dissolve azadirachtin with a cosolvent;

[0023] Then add 1 / 3 of the total amount of emulsifier and solvent to fully emulsify;

[0024] Then add the antifreeze and stabilizer and mix well; and

[0025] Finally the rest of the solvent was added and stirring was carried out for 0.5-1 hour.

[0026] Several specific examples of the azadirachtin emulsifiable concentrate composition of the present invention are given below.

[0027] Azadirachtin cream composition 1 (The ratio of each component is weight ratio)

[0028] Azadirachtin: (0.3%);

[0029] Emulsifier: Sor...

Abstract

The invention discloses an azadirachtin emulsion composition and a preparation method of the azadirachtin emulsion composition. The azadirachtin emulsion composition consists of azadirachtin, an emulsifying agent, a penetrating agent, a stabilizing agent, an antifreeze, a cosolvent and a solvent, wherein the content (weight) of all the components are as follows: 0.3%-1% of the azadirachtin, 8%-12% of the emulsifying agent, 5%-8% of the penetrating agent, 5%-10% of the stabilizing agent, 5%-10% of the antifreeze, 5%-10% of the cosolvent and the rest of the solvent. Due to the synergistic effects of the components of the azadirachtin emulsion composition, the azadirachtin can be sufficiently dissolved. In addition, as the plant oil solvent is adopted, the toxicity of the solvent is greatly reduced, and an obtained preparation is environment-friendly and safe.

Description

technical field [0001] The invention relates to azadirachtin emulsifiable oil composition and a preparation method thereof. Background technique [0002] The emulsifiable concentrate is a transparent liquid processed from water-insoluble raw materials, organic solvents such as benzene and xylene, and emulsifiers. It will not be turbid, stratified, or precipitated after being sealed and stored at room temperature for two years. It can be quickly and evenly dispersed when added to water. into an opaque emulsion. The characteristics of the emulsifiable concentrate are: high drug efficacy, convenient application and relatively stable properties. Due to its long history and mature processing technology, EC has many varieties, large output and wide application range. It is still a main dosage form of pesticides, but there are big problems in its use. [0003] The key to the EC problem is the solvent. At present, the solvents used in my country's EC are mainly volatile light arom...
