Ibisobanuro bigufi:
Izina ry'igicuruzwa: Hydroquinone
CAS: 123-31-9
MF: C6H6O2
MW: 110.11
IMITERERE:
Hydroquinone (HQ) ikorwa binyuze mu kugabanya aniline cyangwa phenol, binyuze mu kugabanya quinone, cyangwa bitewe n'uburyo acetylene na monoxide ya karuboni ikora. Hydroquinone ibaho mu buryo busanzwe nk'ikinyabutabire cya glucose ether, kizwi kandi ku izina rya arbutin, mu mababi y'ibimera byinshi no mu mbuto, ndetse n'imwe mu miti ikoreshwa mu kurinda udukoko twa bombardier, umuryango wa Carabidae.

Imikoreshereze
Koresha nk'umusemburo wo kugabanya no guteza imbere amafoto; nk'umusemburo mu kumenya ingano nto ya fosifate; nk'umusemburo urwanya ibara ry'uruhu.
Hydroquinone ni umuti utuma ibara ry'uruhu rigaragara mu mavuta yo kwisiga. Hydroquinone yivanga na ogisijeni vuba cyane kandi ikaba umukara iyo ishyizwe mu kirere. Nubwo ibaho mu buryo busanzwe, iyi sintetike ni yo ikoreshwa cyane mu kwisiga. Gushyira ku ruhu bishobora gutera ubwivumbure no kongera ubushobozi bwo kumva izuba. Hydroquinone ishobora gutera kanseri kandi ifitanye isano no gutera ochronosis, ihinduka ry'uruhu. Ikigo gishinzwe kurwanya indwara zanduza uruhu cya Amerika (US FDA) cyabujije hydroquinone gukoresha imiti yo kwisiga ya oTC, ariko cyemerera 4% mu bicuruzwa bya muganga. Ikoreshwa ryayo mu kwisiga rirabujijwe mu bihugu bimwe na bimwe by'i Burayi no muri Ositaraliya.
Agonist ya K channel, igabanya umuvuduko ukabije w'amaraso
igabanya ubukana bw'ibinure birinda polimeri ya resin monomers imurika uruhu rwijimye, ikagira urumuri rugaragara
Igabanya kandi ikora amafoto; antioxidant; igabanya ubukana bwa polymer zimwe na zimwe; ikora hagati mu gukora amarangi n'amabara amwe; mu buryo bwo kwisiga.
Gupakira no Kohereza
25KG/igikapu cyangwa nk'uko umukiriya abikeneye.
Ni iy'ibicuruzwa rusange kandi ishobora gutangwa binyuze mu nyanja no mu kirere
Bika kandi ubibike
Igihe cyo kubika: Amezi 24 uhereye igihe byakorewe mu ipaki y’umwimerere idafunguye, bibitswe ahantu hakonje kandi humutse, kure y’izuba ryinshi, amazi.
Ububiko bufite umwuka uhagije, Butuma ibintu bishya bishyuha, butandukanyijwe n'ibikomoka kuri okiside, aside.
