Preparation and Characterization of Alternative Oil-in-Water Emulsion Formulation of Deltamethrin

Walaa El-Sayed & Tahany G. M. Mohammad · Journal of Experimental Agriculture International · 2013

The purpose of this study was to prepare a stable oil-in-water emulsion formulation of deltamethrin. Oil-in-water emulsion was prepared by using a two-step procedure. Stability studies were performed at different accelerated conditions (0°C and 54°C) to predict the stability of t...
