Abstract

Microemulsions are regarded as one of the most promising pesticide formulations. However, formulation of pesticide microemulsions is not simple. Obtaining efficient, scientific and inexpensive formulation designs is challenging. In this work, cyhalothrin was used as a pesticide sample, and a systematic study on microemulsion formula design was carried out based on its pseudo-ternary phase diagram and the orthogonal design method. An explanation of the use of our approach is included to assist the formulator, and the development of a 5.28% w/w cyhalothrin microemulsion is described.

Kurzfassung

Mikroemulsionen werden als die vielversprechendste Möglichkeit für Formulierungen mit Pestiziden angesehen. Derartige Formulierungen sind jedoch nicht einfach zu erzeugen. Die Herstellung von effizienten, wissenschaftlichen und kostengünstigen Formulierungen ist anspruchsvoll. In dieser Arbeit wurde Cyhalothrin als Modellpestizid eingesetzt. Auf Basis des pseudo-ternären Phasendiagramms und der „Orthogonal design“-Methode wurde eine systematische Studie über Herstellungsschemata von Mikroemulsionen durchgeführt. Im Hinblick auf den Formulierer wird die Anwendung unseres Ansatzes erklärt und die Entwicklung einer Mikroemulsion mit einem Cyhalthringehalt von 5,28% w/w beschrieben.
