Problems solved by technology

[0006] 1. The cost of auxiliary materials is high: the amount of organic solvent is large, and the cost is relatively high compared to aqueous solution
[0007] 2. High manufacturing cost: the manufacturing process requires heating and cooling, consumes a lot of energy, and the manufacturing cost is high
[0008] 3. The drug has poor stability. Generally, toltrazuril should be dissolved in an organic solvent at a temperature higher than 120°C. At high temperature, the stability of toltrazuril is poor, and the quality is difficult to control

Abstract

The invention discloses a Toltrazuril suspending agent dispersible in water and a method for preparing the same. The Toltrazuril suspending agent comprises 1 to 15 percent of Toltrazuril, 0.01 to 2.0 percent of a surfactant, 0.01 to 2.0 percent of an emulsifier, 0.1 to 0.3 percent of a preservative, 0.2 to 2.0 percent of a flocculant, 0.1 to 2.0 percent of a suspending aid, 1 to 20 percent of a wetting agent and 40 to 88 percent of purified water.

Description

technical field [0001] The invention relates to a toltrazuril suspension preparation and a preparation method thereof. Background technique [0002] Chicken coccidiosis is a parasitic disease that seriously harms the poultry industry produced by Eimeria. There are 7 species of Eimeria parasitizing in chicken intestines, namely Eimeria tenella, E.acervulina, Eimeria poisonous ( E. necatrix), E. maxima, E. mitis, E. brinetti and E. precocious (E. .praecox). Various coccidia parasitize in different parts of the digestive tract of chickens. Eimeria tenella parasitizes in the cecum, Eimeria heaps parasitizes in the duodenum, Eimeria giant and Eimeria venom Parasitic in the small intestine, Eimeria brucei parasitizes in the lower small intestine and rectum. [0003] Chicken coccidiosis is a kind of parasitic disease that generally occurs all over the world and is very harmful to the chicken industry. The economic losses it caused were staggering. Among many mass diseases, ch...
