This study investigates the feasibility of amphiphilic chitosan derivatives, namely oleoyl carboxymethyl chitosan (OCMCs), N,N-dimethylhexadecyl carboxymethyl chitosan (DCMCs) and deoxycholic acid carboxymethyl chitosan (DACMCs) as carrier agents for rotenone in water-insoluble pesticide formulations. This research is divided into three parts, such as characterisation studies, performance studies and pot experiments. The characterisation studies were carried out using Fourier Transform Infrared (FTIR) Spectrometer, Proton Nuclear Magnetic Resonance (1H NMR) Spectrometer, CHN-O Elemental Analyser (CHN-O), Transmission Electron Microscope (TEM), Differential Scanning Calorimeter (DSC) and Thermogravimetric Analyser (TGA). The critical micelle concentration (CMC) of amphiphilic chitosan derivatives was determined using a Fluorescence Spectrometer. The ability of OCMCs, DCMCs and DACMCs to load and release rotenone in vitro system was determined using a High Performance Liquid Chromatograp.....
