Imikoreshereze
aside ascorbic glucoside, izwi kandi nka VC glucoside, ifite izina rya siyansi OAD-pyran glucosyl-L-ascorbic acid (2-OaD-glucopyranosyl-L-ascorbic acid, mu magambo ahinnye nka AA-2G), ni ikintu kiva muri VC gifite uburemere bwa molekile 338.27. Aho gushonga ni 158.5-159.5℃. Bitewe n'ibibi bya VC nko kudakomera no koroshya ogisijeni, aside ascorbic glucoside, igicuruzwa gisimbura VC, cyavuyemo. Ishobora gusimbura VC nk'ikintu gitera aside, gigabanya, antioxidant, bleaching agent na stabilizer, kandi ikoreshwa cyane mu mavuta yo kwisiga, ibiribwa n'imiti.
Nyuma yuko aside ascorbic glucoside ihinduwe vitamine C hanyuma ikinjira mu turemangingo tw'uruhu, bigabanya cyane ikorwa rya melanin binyuze mu kubuza imikorere ya tyrosinase. Kubuza tyrosinase gutuma dopaquinone igabanuka, ikaba ari ikintu kiri hagati mu gukora melanin. Indi nyungu ni uko ihindura dopaquinone icyarimwe ikaba levodopa, ikagabanya melanin yamaze gukorwa bityo ikagabanya ibara ry'uruhu. 2. Irwanya kwangirika kwa UV no kubuza kwangirika kwa ultraviolet ku turemangingo. Nyuma yuko aside ascorbic glucoside ihinduwe vitamine C, ishobora kugabanya cyane radicals free radicals ikorwa n'imirasire ya ultraviolet mu ruhu, ikagabanya cyane kwangirika k'uruhu kandi ikagira uruhare mu kurinda uruhu mu bicuruzwa bikingira izuba.
Ascorbic acid glucoside ni imwe mu nyongeramusaruro zemewe na Minisiteri y'Ubuzima kandi izwiho kuba ikomoka kuri vitamine C idahinduka. Ni nayo ikoreshwa cyane mu nganda zikomeye muri iki gihe mu nganda. Urugero, L 'Oreal ikoresha C-glycoside derivatives mu guhuza n'ibindi bice kugira ngo ikumire cyangwa ivure ibimenyetso byo gusaza mu mubiri cyangwa mu ruhu rwo mu maso. Ascorbic acid glucoside ntabwo igira ingaruka nziza zo kwera gusa, ahubwo inagira imiterere ihamye ya shimi kandi ntitera uruhu ku ruhu. Ikoreshwa cyane mu kwisiga mu gihugu no mu mahanga kandi yemejwe n'abaturage. Imbonerahamwe ikurikira igaragaza uko ibintu bikunze gukoreshwa mu kwisiga.
Gupakira no Kohereza
25KG/Ingoma 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.
