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
The present invention relates to the nimbin emulsion composition and method of making the same.
Background technology
Missible oil is the transparence liquid that is processed by the configuration of water-fast former medicine, organic solvent-benzene, dimethylbenzene etc. and emulsifier, the normal temperature lower seal deposit 2 years generally can be not muddy, layering and precipitation, be added to the water rapid Uniform Dispersion and become opaque emulsion.The characteristics of missible oil are: drug effect is high, uses conveniently, and character is more stable.Because the history of missible oil is longer, have ripe process technology, so wide in variety, output is large, applied range remain at present a main formulation of agricultural chemicals, but it in use exists very large problem.
The key of missible oil problem is solvent, and at present the solvent that uses of China's missible oil is mainly volatile light aromatic solvent, this solvent has that toxicity is higher, inflammable, long half time, to shortcomings such as environmental influence are large.In addition, also use the solvent that more toxicity is higher or have teratogenesis in some other formulation, as methyl alcohol, dimethyl formamide etc., therefore, if can use the solvent that relative toxicity is lower, safety is higher, missible oil is still a kind of good formulation.
Nimbin emulsion is a kind of agricultural chemicals that adopts the missible oil formulation, and wherein nimbin is a kind of plant resource active substance that the effect of multiple poisoning insect is arranged, and is present in seal Melia seal chinaberry plant species core and leaf.Nimbin is because easily decomposition water baseization product development difficulty is larger in water, and missible oil will be the main formulation of nimbin at present.Therefore, how the formulation of nimbin emulsion being optimized, particularly how various auxiliary agent formulations in missible oil being improved, make more Environmental Safety of nimbin preparation, is the technical problem that needs to be resolved hurrily.
Summary of the invention
The nimbin emulsion composition that the purpose of this invention is to provide a kind of Environmental Safety more.
According to a first aspect of the invention, provide a kind of nimbin emulsion composition.Said composition is by nimbin, emulsifier, bleeding agent, stabilizing agent, antifreeze, cosolvent and solvent composition, and wherein the content of each component (weight) is as follows:
Nimbin: 0.3%-1%; Emulsifier: 8%-12%; Bleeding agent: 5%-8%; Stabilizing agent: 5%-10%; Antifreeze: 5%-10%; Cosolvent: 5%-10%; Solvent: surplus.
Solvent can be selected from the vegetable oil such as volatile oil extracted from eucalyptus' leaves or twigs, turpentine-based vegetable oil, neem oil and Jatropha curcas oil.
Emulsifier can be selected from sorbitan monostearate, polyoxyethylene sorbitan ether monoleate and fatty alcohol-polyoxyethylene ether.
Bleeding agent can be selected from NP class non-ionic surface active agent, AEO class non-ionic surface active agent and organosilicon.
Stabilizing agent can be selected from 2,6 BHTs, sorbic acid, polyethylene glycol glycidol ether, cresyl glycidyl ether, butyl glycidyl ether and two (2,2,6,6-tetramethyl-piperidyl) sebacate.
Antifreeze can be selected from ethylene glycol, glycerine and sorbierite.
Cosolvent can be selected from ethanol and dibasic ester.
The preparation method of above-mentioned nimbin emulsion composition is provided according to a further aspect in the invention.The method comprises:
Fully dissolve nimbin with cosolvent;
Then add 1/3 of emulsifier and solvent total amount to carry out fully emulsified;
Add again antifreeze and stabilizing agent and mix; And
Add at last remaining solvent and stir.
By the prepared nimbin emulsion composition of method of the present invention, due to the mutual synergistic effect between its component, thereby make nimbin can be able to abundant dissolving.In addition, owing to having adopted vegetable oil solvent, thereby greatly reduced solvent toxicity, made gained preparation Environmental Safety more.
Embodiment
Describe nimbin emulsion composition and method of making the same of the present invention in detail below in conjunction with specific embodiment.
Nimbin emulsion composition of the present invention is by nimbin, emulsifier, bleeding agent, stabilizing agent, antifreeze, cosolvent and solvent composition, and its preparation method is as follows:
