IHydroquinone sisixhobo esikhanyisa ibala elisetyenziselwa ukwenza iikhrimu zokuthambisa. IHydroquinone idibana neoksijini ngokukhawuleza okukhulu kwaye iba mdaka xa isesichengeni somoya. Nangona isenzeka ngokwemvelo, inguqulelo eyenziweyo yeyona isetyenziswa ngokuqhelekileyo kwizinto zokuthambisa. Ukusetyenziswa eluswini kunokubangela ukwaliwa kwaye kwandise uvakalelo lwelanga lolusu. IHydroquinone inokubangela umhlaza kwaye inxulunyaniswa nokubangela i-ochronosis, ukujika kombala wolusu. I-US FDA iye yavala i-hydroquinone kwi-oTC cosmetic formulations, kodwa ivumela isi-4 sepesenti kwiimveliso ezimiselweyo.

I-1,4-dihydroxybenzene, ekwaziwa njenge-hydroquinone, yimathiriyeli ekrwada ebalulekileyo yeekhemikhali. Imbonakalo yayo yikristale emhlophe eyi-acicular. I-1,4-dihydroxybenzene isetyenziswa ngokubanzi njengento ebalulekileyo ekrwada, ephakathi kunye ne-arhente encedisayo kumayeza, izitshabalalisi, iidayi kunye nerabha. Isetyenziswa kakhulu njengomphuhlisi, idayi ye-anthraquinone, idayi ye-azo, irabha i-antioxidant kunye ne-monomer polymerization inhibitor, i-stabilizer yokutya kunye ne-coating antioxidant, i-petroleum anticoagulant, i-synthetic ammonia catalyst, njl.
