Isicelo
Organic intermediates.
Isetshenziswa njenge-preservative, i-ejenti ye-antibacterial,
Isetshenziselwa ukudla, izimonyo, kanye nemithi.
Ingasetshenziswa futhi njenge-reagent yokuhlaziywa kwe-organic.
Isitoreji
Ipakishwe ngesigubhu sensimbi esifakwe isikhwama sepulasitiki. Azikho izidingo ezikhethekile zokugcinwa nezokuthutha.
Ukuzinza
Lo mkhiqizo uyinto ebulala amagciwane kakhulu ene-phenol coefficient engu-8.0. Ubuthi obuphansi kakhulu, akukho ukucasuka esikhumbeni somuntu.
Incazelo yezinyathelo zosizo lokuqala ezidingekayo
Iseluleko esijwayelekile
Bonana nodokotela. Bonisa leli phepha ledatha yokuphepha kudokotela osendaweni.
Adonse umoya
Uma uhogelwe, yisa isiguli emoyeni omusha. Uma ukuphefumula kuyeka, nikeza ukuphefumula okwenziwa. Bonana nodokotela.
ukuthintana kwesikhumba
Hlanza ngensipho namanzi amaningi. Bonana nodokotela.
ukuthintana kwamehlo
Hlanza kahle ngamanzi amaningi okungenani imizuzu eyi-15 bese ubonana nodokotela.
Ukungeniswa
Ungalokothi unikeze noma yini ngomlomo kumuntu oqulekile. Hlanza umlomo wakho ngamanzi. Bonana nodokotela.
