摘要
本文通过对润湿分散剂、增稠剂和pH调节剂等助剂的筛选,最终确定了40%硝磺草酮悬浮剂的最佳配方:硝磺草酮原药40.0%、SD-813为2.0%、SD-208为3.0%、乙二醇4.0%、硅酸镁铝1.0%、黄原胶5.0%、柠檬酸2.0%、AFE-3168 0.2%、去离子水补足。实验结果表明:该配方制备的悬浮剂平均粒径<4μ,悬浮率95%以上,其它各项指标均达到悬浮剂的要求。
In this paper, mesotrione 40% suspension concentrate was prepared by optimizing the major formulants such as wetting and dispersing agents, thickening agents as well as pH controlling agents. The optimum formula was determined as follows： mesotrione 40. 0%, SD -813 2. 0%, SD- 208 3.0%, ethylene glycol 4. 0%, magnesium aluminum silicate 1.0%, xanthan gum 5.0%, citric acid 2. 0%, AFE -3168 0. 2% and water added to 100%. The resuhs showed that the average particle size of SC product with the optimum formula was less than 4 μm and the suspen- sion rate was over 95%. All the other parameters complied with the requirements for suspension concentrate formulation.
