DEET raws li tshuaj tua kab, rau ntau yam khoom thiab kua tshuaj yoov tshaj cum series ntawm cov tshuaj tiv thaiv tseem ceeb, tiv thaiv yoov tshaj cum muaj txiaj ntsig tshwj xeeb. Nws tuaj yeem siv los tiv thaiv tsiaj los ntawm kev puas tsuaj los ntawm kab tsuag, tiv thaiv mites thiab lwm yam. Tag nrho peb lub isomers muaj cov tshuaj tua yoov tshaj cum, thiab meso-isomer yog qhov muaj zog tshaj plaws. Kev npaj: 70%, 95% kua.
yas nruas, nqa nyhav 25 kg ib chim; Packing raws li cov neeg siv khoom xav tau. Cov khoom no yuav tsum tau muab khaws cia rau hauv lub thawv kaw thaum lub sijhawm khaws cia thiab thauj mus los, thiab khaws cia rau hauv qhov chaw txias, qhuav thiab zoo-ventilated.
