Synthesis and aplication CTAC surfactant from palmityl alcohol in insecticide emulsifiable concentrate formulation

Abstract

Surfactants become a very important component in pesticide product as they afford different properties and also make stable and homogeneous possible formulation. Surfactant usually produced from petroleum and can be harmful for environment. Palm oil is one of the most potentials resources that can derive to produce surfactant. This study aims to determine characteristic of CTAC surfactant and to get the best insecticide formulation prototype. CTAC surfactant produce from palmityl alcohol by two step process. Charactheristics of this surfactant are density of 0,9968 g/cm3, surface tension of 27,47 dyne/cm, contact angle of 20,39 and pH of 9,16. Emulsifiable concentrate formulation contain of active ingredient and co-formulant. Surfactant DEA and CTAC are used as surfactant for EC formulation. Physical properties of formulation are surface tension 33,4-36,3 dyne/cm, density 0,8756-0,9098 g/cm3, particle size 1,23-4,48 μm and pH 6,86-7,44. The best formulation is with adding DEA surfactant about 5% and CTAC 1%.
