Kufotokozera Kwachidule:
Dzina la Mankhwala: Hydroquinone
CAS:123-31-9
MF: C6H6O2
MW: 110.11
KAYAMBIDWE:
Hydroquinone (HQ) imapangidwa ndi okosijeni wa aniline kapena phenol, mwa kuchepetsa quinone, kapena chifukwa cha acetylene ndi carbon monoxide. Hydroquinone imapezeka mwachilengedwe ngati glucose ether, yomwe imadziwikanso kuti arbutin, m'masamba a zomera zambiri ndi zipatso, komanso ngati imodzi mwa mankhwala omwe amagwiritsidwa ntchito poteteza kachilomboka ka bombardier, banja la Carabidae.

Kagwiritsidwe Ntchito
Gwiritsani ntchito ngati chochepetsera zithunzi komanso chopangira zinthu; ngati chothandizira pozindikira kuchuluka kwa phosphate pang'ono; ngati antioxidant.
Hydroquinone ndi mankhwala owunikira utoto omwe amagwiritsidwa ntchito mu mafuta oyeretsera. Hydroquinone imasakanikirana ndi mpweya mwachangu kwambiri ndipo imakhala yofiirira ikayikidwa mumlengalenga. Ngakhale kuti imachitika mwachilengedwe, mtundu wopangidwa ndi womwe umagwiritsidwa ntchito kwambiri mu zodzoladzola. Kugwiritsa ntchito pakhungu kungayambitse ziwengo ndikuwonjezera kukhudzidwa ndi dzuwa pakhungu. Hydroquinone ikhoza kuyambitsa khansa ndipo imagwirizana ndi kuyambitsa ochronosis, kusintha kwa mtundu wa khungu. US FDA yaletsa hydroquinone ku oTC cosmetic formulations, koma imalola 4 peresenti mu mankhwala operekedwa ndi dokotala. Kugwiritsa ntchito kwake mu zodzoladzola ndikoletsedwa m'maiko ena aku Europe ndi ku Australia.
K channel agonist, antihypertensive
chochepetsera chimaletsa polymerization ya ma monomers a resin kuwunikira khungu lakuda, kulabadira kuwala
Chochepetsa ndi kupanga zithunzi; choletsa kuwononga chilengedwe; chothandizira kukhazikika kwa ma polima ena; chapakati popanga utoto ndi utoto wina; mu zokongoletsa.
Kulongedza ndi Kutumiza
25KG/Chikwama kapena malinga ndi zosowa za makasitomala.
Ndi katundu wamba ndipo amatha kutumizidwa kudzera m'nyanja ndi mlengalenga
Sungani ndi kusunga
Nthawi yosungiramo zinthu: Miyezi 24 kuyambira tsiku lopangidwa m'maphukusi oyambirira osatsegulidwa, osungidwa pamalo ozizira komanso ouma, kutali ndi dzuwa, madzi.
Nyumba yosungiramo zinthu zopumira mpweya, Youma pang'ono, Yosiyana ndi ma oxidants, ma acid.
