Inkcazo emfutshane:
Igama leMveliso: iHydroquinone
I-CAS: 123-31-9
I-MF: C6H6O2
I-MW: 110.11
ULWAKHIWO:
IHydroquinone (HQ) iveliswa yi-oxidation ye-aniline okanye i-phenol, ngokunciphisa i-quinone, okanye ngenxa ye-acetylene kunye ne-carbon monoxide. IHydroquinone ivela ngokwendalo njenge-glucose ether, eyaziwa ngokuba yi-arbutin, kumagqabi ezityalo ezininzi nakwiziqhamo, kunye nenye yeearhente ezisetyenziswa kwinkqubo yokukhusela i-bombardier beetle, usapho lweCarabidae.

Ukusetyenziswa
Sebenzisa njengesinciphisi kunye nomphuhlisi wezithombe; njenge-reagent ekumiselweni kobungakanani obuncinci be-phosphate; njenge-antioxidant.
I-hydroquinone sisithako sokukhanyisa umbala esisetyenziswa kwiikhrimu zokumhlophe. I-Hydroquinone idibana neoksijini ngokukhawuleza kwaye iba mdaka xa isetyenziswa emoyeni. Nangona isenzeka ngokwendalo, uhlobo oluyilwe ngokwemvelo lolona lusetyenziswa kakhulu kwiikhasmethi. Ukusetyenziswa eluswini kunokubangela i-allergy kunye nokwandisa uvakalelo lwelanga lolusu. I-Hydroquinone inokubangela umhlaza kwaye inxulunyaniswa nokubangela i-ochronosis, ukutshintsha kombala wolusu. I-US FDA iyithintele i-hydroquinone kwiifomyula ze-oTC cosmetic, kodwa ivumela i-4% kwimveliso kagqirha. Ukusetyenziswa kwayo kwiikhasmethi akuvumelekanga kwamanye amazwe aseYurophu nase-Australia.
I-agonist yesiteshi se-K, i-antihypertensive
iarhente yokunciphisa ithintela ukwenziwa kwe-polymerization yee-resin monomers ikhanyisa ulusu olumnyama, ichukumise ukukhanya
Isinciphisi kunye nomphuhlisi weefoto; i-antioxidant; iarhente yokuzinzisa ezinye iipolymers; iphakathi ekuvelisweni kweedayi kunye neepigment; kwimixube yokuhombisa.
Ukupakishwa kunye nokuthunyelwa
25KG/ibhegi okanye ngokweemfuno zabathengi.
Yeyokwempahla eqhelekileyo kwaye inokuhanjiswa ngolwandle nangomoya
Gcina kwaye ugcine
Ixesha lokuphelelwa: Iinyanga ezingama-24 ukususela kumhla wokwenziwa kwayo kwiphakheji yokuqala engavulwanga igcinwe kwindawo epholileyo neyomileyo kude nelanga elithe ngqo, amanzi.
Indawo yokugcina umoya, Ukomisa kubushushu obuphantsi, Yahlulwe kwii-oxidants, ii-asidi.
