Effect of surfactants on the particle properties of lambda-cyhalothrin nanosuspensions.^a

aThe nanosuspensions containing 1% (w/w) lambda-cyhalothrin and 0.5% (w/w) surfactant were prepared at a shearing speed of 10000 rpm and 80°C. bSDS: 1-dodecanesulfonic acid sodium salt; SDBS: sodium dodecylbenzenesulfonate; MRES: maleic rosin-polyoxypropylene-polyoxyethylene ether sulfonate; SL: sodium ligninsulfonate; CTAB: hexadecyltrimethylammonium bromide; Tween 80: polyoxyethylene sorbitan monooleate; PVP K30: polyvinylpyrrolidone K30; HPMC: hydroxypropyl methylcellulose. cD90: particle size expressed by the 90% diameter percentile. dPDI: polydispersity index. eS.D.: standard deviation of three measurements.
