Abstract

In this study, we report the formulation of sustainable pesticide microemulsions using green surfactants and solvents. Sugar-based surfactant was selected as emulsifiers, and biomass-based ethyl lactate served as the co-solvent, with a low-energy emulsification method employed to produce high-efficiency meperfluthrin microemulsions. The results showed that the microemulsions had a particle size ranging from 30 to 60 nm, with a maximum meperfluthrin loading of 32.4% and an encapsulation rate exceeding 90%. The microemulsions had good stability under various environmental conditions. Compared to commercially available meperfluthrin products, the microemulsions had a lower organic solvent content and a higher loading capacity, due to pyrethroid pesticides having better solubility in ethyl lactate. Furthermore, the toxicity of microemulsions was significantly reduced and met environmental protection standards. This study provides a new solution and practical basis for the green and sustainable development of pesticide formulations.

含绿糖基表面活性剂的高负载超氟菊酯微乳的制备与表征

在这项研究中，我们报告了绿色表面活性剂和溶剂的可持续农药微乳剂的配方。以糖基表面活性剂为乳化剂，以生物质基乳酸乙酯为助溶剂，采用低能乳化法制备高效过氟菊酯微乳液。结果表明，微乳的粒径为30 ~ 60 nm，超氟菊酯的最大载药量为32.4%，包封率超过90%。该微乳在各种环境条件下均具有良好的稳定性。与市售的超氟菊酯产品相比，由于拟除虫菊酯类农药在乳酸乙酯中具有更好的溶解度，因此微乳的有机溶剂含量较低，负载能力较高。微乳的毒性显著降低，达到环保标准。本研究为农药配方的绿色可持续发展提供了新的解决方案和实践依据。

期刊介绍： Sustainable Chemistry and Pharmacy publishes research that is related to chemistry, pharmacy and sustainability science in a forward oriented manner. It provides a unique forum for the publication of innovative research on the intersection and overlap of chemistry and pharmacy on the one hand and sustainability on the other hand. This includes contributions related to increasing sustainability of chemistry and pharmaceutical science and industries itself as well as their products in relation to the contribution of these to sustainability itself. As an interdisciplinary and transdisciplinary journal it addresses all sustainability related issues along the life cycle of chemical and pharmaceutical products form resource related topics until the end of life of products. This includes not only natural science based approaches and issues but also from humanities, social science and economics as far as they are dealing with sustainability related to chemistry and pharmacy. Sustainable Chemistry and Pharmacy aims at bridging between disciplines as well as developing and developed countries.
