Cell Solution® Protection fibers are natural cellulosic manmade fibers and provide effective and durable protection against insects - such as ticks and mosquitoes. Cell Solution® Protection fibers can be easily processed into textiles and have consistent dyeability whan following the recommended processing/finishing method. Permethrin is a chemical categorized in the pyrethroid, insecticide group. Permethrin is used as an insecticide in agriculture or as a personal protective measure (cloth impregnant, used primarily for US military uniforms and mosquito nets). The objective of this work was the determination of Permethrin from functionalized textile materials. Permethrin has four stereoisomers (two enantiomeric pairs), arising from the two stereocenters in the cyclopropane ring. (1R,3S)-trans and (1R,3R)-cis enantiomers are responsible for the insecticidal properties of permethrin. We performed the extraction of Permethrin from textile materials using accelerated solvent extraction (ASE), followed by identification of permethrin and cuantification by liquid chromatography with spectrophotometric detection (HPLC-MWD) and we confirmed the results by gas chromatography with mass spectrometric detection (GC-MS). Both analytical methods have contributed to determination of trans and cispermethrin.
