Gusaba

Hydroquinone nigikoresho cyo kumurika pigment ikoreshwa mumavuta yo kwisiga.Hydroquinone ikomatanya na ogisijeni byihuse kandi ihinduka umukara iyo ihuye n'umwuka.Nubwo bibaho bisanzwe, verisiyo yubukorikori niyo isanzwe ikoreshwa mu kwisiga.Gukoresha uruhu birashobora gutera allergique kandi bikongerera izuba izuba.Hydroquinone ishobora kuba kanseri kandi ifitanye isano no gutera ochronose, ibara ryuruhu.US FDA yabujije hydroquinone kwisiga oTC, ariko yemerera 4 ku ijana mubicuruzwa byandikirwa.

1,4-dihydroxybenzene, izwi kandi nka hydroquinone, ni ibikoresho byingenzi bya shimi.Igaragara ryayo ni kirisiti yera ya kirisiti.1,4-dihydroxybenzene ikoreshwa cyane nk'ibikoresho by'ibanze, hagati kandi bifasha imiti, imiti yica udukoko, amarangi na reberi.Ikoreshwa cyane cyane nkuwitezimbere, irangi rya anthraquinone, irangi rya azo, reberi antioxydeant na monomer polymerisation inhibitor, stabilisateur ibiryo na coating antioxidant, peteroli anticoagulant, catalizike ya ammonia cataliste, nibindi. na zahabu.
