Hydroquinone chinhu chinovheneka pigment chinoshandiswa mukuchenesa makirimu. Hydroquinone inosanganiswa neokisijeni nekukasira uye inoita shava kana yaiswa mumhepo. Kunyange zvichingoitika zvoga, shanduro yekugadzira ndiyo inowanzoshandiswa muzvizoro. Kushandisa paganda kunogona kukonzera allergic reaction uye kuwedzera ganda zuva senitivity. Hydroquinone inogona kukonzera carcinogenic uye inosanganiswa nekukonzera ochronosis, kushanduka kweganda. US FDA yakarambidza hydroquinone kubva kuOTC cosmetic formulations, asi inobvumira 4 muzana muzvigadzirwa zvemishonga.
1,4-dihydroxybenzene, inozivikanwawo sehydroquinone, yakakosha kemikari mbishi zvinhu. Chitarisiko chayo chichena acicular crystal. 1,4-dihydroxybenzene inoshandiswa zvakanyanya sechinhu chakakosha, chepakati uye chekubatsira mumiririri wemishonga, mishonga yezvipembenene, dhayi uye rabha. Inonyanya kushandiswa semugadziri, anthraquinone dhayi, azo dhayi, rabha antioxidant uye monomer polymerization inhibitor, chikafu stabilizer uye coating antioxidant, petroleum anticoagulant, synthetic ammonia catalyst, etc. Inogona zvakare kushandiswa seanalytical reagent, inoderedza mumiriri uye mugadziri wemhangura. nendarama.
