How to solve the Kung Fu (cyhalothrin) preparations instability?

Friends Yu Fei Forum: Kung Fu decomposition of the problem is diversification. 

More likely to affect the situation, generally classified as follows: 

1, the preparation of the form, which the dosage form chosen. Dosage form itself and the effort as some of the shortcomings caused by the formation. For example: EW environment in the effort easier in the water decomposition; processing WP or WDG thermal decomposition process and so on. 

2, preparation of the PH effect, over-acid and slightly alkaline decomposition can lead to martial arts. Including: preparation, solvent pH, auxiliary components (additives) of the PH 

3, it is easy to overlook, the sample analysis method to deal with imprecise, resulting in measurement errors. 

4, the original synthetic route of drug technology, leading to the original drug's purity and impurity caused by decomposition, this is a common 

5 isomers of the problem, the original drug in their body is not more efficient, of course, easier to break down. Because in the course of the general store there is a high physical body to the inefficient conversion process. 

Between the Southern Mo: I think the preparation will lead to decomposition of the photosensitive composition 

zhpzhang: Kung Fu ME, EW should note that the detection method. 

4.5% of our high chloride ME is a random inspection in a province that is 0, the problem is that the inspection unit according to EC approach to testing. The results have become a joke.
