Hydroquinone (HQ) (CAS: 123-31-9) e gaosia e ala i le faʻamaʻiina o le aniline poʻo le phenol, e ala i le faʻaitiitia o le quinone, poʻo le faʻaalia o le acetylene ma le carbon monoxide.
O le Hydroquinone o se mea faʻaitiitiga faʻaaogaina i totonu o se atinaʻe ata, lea e polymerize i le i ai o faʻamaʻi faʻamaʻi.I totonu o fale gaosi oloa e mafai ona tupu e aofia ai le bacteriostatic agent, vailaʻau, faʻaogaina o fulufulu, afi afi, vali, vailaʻau faʻasolosolo, palasitika, faʻapipiʻi maʻa, ma styrene monomers.
Fa'aaogā e fa'aitiitiga ata ma fa'atupu;e fai ma sui i le fuafuaina o ni vaega laiti o phosphate;e pei o le antioxidant.Depigmentor.
Fa'aitiitiga ata ma atina'e;antioxidant;mea fa'amautu mo nisi polymers;vaeluagalemu i le gaosiga o nisi o vali ma lanu;i mea teuteu teuteu.
O le Hydroquinone e fa'aaogaina i tagata fa'atupu ata (uliuli ma papa'e, X-ray, ma microfilms), i palasitika, i vali lauulu e fai ma antioxidant ma lanu lauulu.O le hydroquinone e maua i le tele o kulimi fa'amalama pa'u.
O le hydroquinone e fa'aoga i luga e togafitia ai fa'afitauli e fa'aalia i le tele o le melanin i le epidermis, e pei o le melasma.I totonu o le Iunaite Setete, o mea e le o fa'atonuina e fa'amalama pa'u o lo'o i ai le hydroquinone i fa'aputuga o le 2% pe itiiti;maualuga fa'atonuga e maua ile talavai.
Fa'aaoga lautele i ata, vali, pa'u, vailaau fa'alafua, vaila'au, vaila'au, polymer inhibitors, vaila'au vaila'au vaila'au desulfurizer, urea synergistic agent, antioxidant, su'esu'ega vaila'au.fa'apea fo'i vaila'au ma vaila'au va'ava'ai.ma intermediate mo vailaau lelei.
E faapogisa pe a aafia i le ea ma le malamalama.Miscible i le vai.O vaifofo e lanu enaena ile ea ona ole fa'ama'iina.Oxidation e matua televave pe a iai le alkali.
Ole hydroquinone ose fa'alavelave pa'u laititi pe a fa'aalia ile vevela.E le fetaui ma vailaʻau faʻamaʻi malosi.E le fetaui foi ma faavae.Ole hydroquinone e tali atu ile okesene ma le sodium hydroxide.E tali atu i masima ferric .O le NaOH vevela ma/po'o le fa'atumauina e mafai ona fa'atupuina le fa'apalapala ole Hydroquinone ile vevela maualuga.(NFPA Pub. 491M, 1975, 385)
O a'afiaga i le hydroquinone i se aofa'iga tele e ala ile taumafaina fa'afuase'i ile gutu e maua ai le oona ma le 'ona.O fa'ailoga o le 'ona e aofia ai, ae le gata i, tautala faanenefu, tinnitus, tetete, lagona o le manava, pua'i, tetete maso, tiga o le ulu, tetete, dyspnea ma le cyanosis mai le methemoglobinemia, koma, ma le pa'u ona o le faaletonu o le manava.O tagata faigaluega faigaluega e tatau ona fa'atagaina e galulue fa'atasi ma lavalava puipui ma ufimata pefu fa'atasi ai ma mata atoa po'o mata tioata e puipuia ai mata, ma i lalo o le fa'atonuga lelei.
E mafai ona pa le ao pefu pe a mumu i totonu o se nofoaga pupuni.E mafai e le Hydroquinone ona tali atu i mea fa'ama'i fa'ama'i ma vave fa'ama'iina i le i ai o mea alkaline.Oxidize i le ea.
