QAUV:
Hydroquinone (HQ) yog tsim los ntawm kev oxidation ntawm aniline lossis phenol, los ntawm kev txo qis ntawm quinone, lossis los ntawm kev sib xyaw ntawm acetylene thiab carbon monoxide. Hydroquinone tshwm sim ntuj tsim ua ib qho glucose ether, tseem hu ua arbutin, hauv nplooj ntawm ntau cov nroj tsuag thiab hauv cov txiv hmab txiv ntoo, nrog rau ib qho ntawm cov neeg sawv cev siv hauv lub tshuab tiv thaiv ntawm bombardier beetle, tsev neeg Carabidae.

Kev Siv
Siv ua tus txo duab thiab tus tsim tawm; ua reagent hauv kev txiav txim siab ntawm cov phosphate me me; ua antioxidant. Depigmentor
hydroquinone yog ib yam khoom siv ua kom cov xim dawb uas siv rau hauv cov tshuaj pleev dawb. Hydroquinone sib xyaw nrog cov pa oxygen sai heev thiab ua xim av thaum raug cua. Txawm hais tias nws tshwm sim ntuj, cov khoom siv hluavtaws yog qhov feem ntau siv hauv cov tshuaj pleev ib ce. Kev siv rau ntawm daim tawv nqaij yuav ua rau muaj kev tsis haum tshuaj thiab ua rau daim tawv nqaij rhiab heev rau lub hnub. Hydroquinone muaj peev xwm ua rau mob qog noj ntshav thiab cuam tshuam nrog kev ua rau ochronosis, qhov kev hloov pauv ntawm daim tawv nqaij. Lub koom haum FDA hauv Tebchaws Meskas tau txwv tsis pub siv hydroquinone los ntawm cov tshuaj pleev ib ce oTC, tab sis tso cai rau 4 feem pua hauv cov khoom siv kho mob. Nws siv hauv cov tshuaj pleev ib ce raug txwv hauv qee lub tebchaws European thiab hauv Australia.
K-channel agonist, tshuaj tiv thaiv ntshav siab
tus neeg sawv cev txo qis tiv thaiv kev sib xyaw ntawm cov resin monomers ua rau cov tawv nqaij tsaus ntuj, ua rau lub teeb ci ntsa iab
Tus neeg txo duab thiab tus tsim tawm; antioxidant; tus neeg sawv cev ruaj khov rau qee cov polymers; nruab nrab hauv kev tsim khoom ntawm qee cov xim thiab cov xim; hauv cov qauv tshuaj pleev ib ce.
Ntim thiab Xa Khoom
25KG / Hnab los yog raws li cov neeg siv khoom xav tau.
Yog cov khoom siv dav dav thiab tuaj yeem xa los ntawm dej hiav txwv thiab huab cua
Khaws cia thiab khaws cia
Lub neej txee: 24 lub hlis txij li hnub tsim khoom hauv cov ntim khoom tsis tau qhib khaws cia rau hauv qhov chaw txias thiab qhuav kom tsis txhob raug tshav ntuj ncaj qha, dej.
Lub tsev rau khoom muaj cua nkag, ziab kom qhuav kub tsawg, Sib cais ntawm cov tshuaj oxidants, cov kua qaub.
