Hydroquinone waa walax iftiimiye midab ah oo loo isticmaalo kiriimyada bleaching.Hydroquinone waxay ku darsataa ogsijiinta si degdeg ah waxayna noqotaa bunni marka ay hawada gasho.Inkasta oo ay si dabiici ah u dhacdo, nooca synthetic waa midka sida caadiga ah loo isticmaalo qurxinta.Codsiga maqaarku wuxuu sababi karaa fal-celin xasaasiyadeed wuxuuna kordhiyaa dareenka maqaarka ee qorraxda.Hydroquinone waa laga yaabo inuu kansar keeno wuxuuna la xiriiraa inuu keeno ochronosis, midabka maqaarka.US FDA waxay ka mamnuucday hydroquinone waxyaabaha la isku qurxiyo ee oTC, laakiin waxay u ogolaataa 4 boqolkiiba alaabada dhakhtarku qoray.
1,4-dihydroxybenzene, sidoo kale loo yaqaan hydroquinone, waa walxo kiimiko ah oo ceeriin ah oo muhiim ah.Muuqaalkeedu waa crystal acicular cad.1,4-dihydroxybenzene waxaa si ballaaran loo isticmaalaa sida walxo ceeriin ah oo muhiim ah, dhexdhexaad ah iyo wakiilka caawiye ee daawada, sunta cayayaanka, midabada iyo caag.Waxaa inta badan loo isticmaalaa sidii horumariye, dheeha anthraquinone, dheeha azo, antioksidanter caag ah iyo monomer polymerization inhibitor, cuntada stabilizer iyo daahan antioxidant, batroolka anticoagulant, kicinta ammonia synthetic, iwm. iyo dahab.
