Incazelo emfushane:
Igama Lomkhiqizo: I-Hydroquinone
I-CAS:123-31-9
I-MF: C6H6O2
I-MW: 110.11
ISAKHIWO:
I-Hydroquinone (HQ) ikhiqizwa yi-oxidation ye-aniline noma i-phenol, ngokunciphisa i-quinone, noma ngenxa yokusabela kwe-acetylene ne-carbon monoxide. I-Hydroquinone ivela ngokwemvelo njenge-glucose ether, eyaziwa nangokuthi i-arbutin, emaqabunga ezitshalweni eziningi nasezithelo, kanye nenye yezinto ezisetshenziswa ekuvikeleni i-bombardier beetle, umndeni i-Carabidae.

Ukusetshenziswa
Sebenzisa njengesinciphisi sezithombe kanye nonjiniyela; njenge-reagent ekunqumeni inani elincane le-phosphate; njenge-antioxidant.
I-hydroquinone iyisithako esikhanyisa umbala esisetshenziswa kuma-creams okumhlophe. I-Hydroquinone ihlangana nomoya-mpilo ngokushesha okukhulu futhi iba nsundu uma itholakala emoyeni. Nakuba kwenzeka ngokwemvelo, uhlobo lokwenziwa yilona oluvame ukusetshenziswa ezimonyweni. Ukusetshenziswa esikhumbeni kungabangela ukusabela kokungezwani komzimba futhi kwandise ukuzwela elangeni lesikhumba. I-Hydroquinone ingase ibe umdlavuza futhi ihlotshaniswa nokubanga i-ochronosis, ukushintsha kombala wesikhumba. I-US FDA ivimbele i-hydroquinone ezinhlotsheni zezimonyo ze-oTC, kodwa ivumela amaphesenti angu-4 emikhiqizweni kadokotela. Ukusetshenziswa kwayo ezimonyweni akuvunyelwe kwamanye amazwe aseYurophu nase-Australia.
I-agonist yesiteshi se-K, elwa nomfutho wegazi ophezulu
i-ejenti yokunciphisa ivimbela ukwenziwa kwe-polymerization kwama-resin monomers kukhanyisa isikhumba esimnyama, kuzwela ukukhanya
Isinciphisi sezithombe kanye nonjiniyela; i-antioxidant; i-ejenti yokuzinzisa kwamanye ama-polymer; iphakathi ekukhiqizweni kwamadayi athile kanye nemibala; ekwakhiweni kwezimonyo.
Ukupakisha Nokuthumela
25KG/Isikhwama noma ngokwezidingo zamakhasimende.
Kungokwempahla evamile futhi kungathunyelwa ngolwandle nangomoya
Gcina futhi ugcine
Isikhathi sokuphila: Izinyanga ezingama-24 kusukela ngosuku lokwenziwa kwento epakishweni lokuqala elingavulwanga, igcinwe endaweni epholile neyomile kude nokukhanya kwelanga okuqondile, amanzi.
Indawo yokugcina izinto enomoya, Ukomisa okuphansi kwezinga lokushisa, Ihlukaniswe nama-oxidants, ama-acid.
