Mu February 2023, European Union Scientific Committee for Consumer Safety (SCCS) inapereka lingaliro lomaliza pa chitetezo chaα-arbutinndiβ-arbutinmu zodzoladzola, ndi whitening zotsatira za nyenyezi pophika arbutin kamodzinso anayambitsa nkhawa makampani.
Kodi arbutin ndi chiyani?
Arbutin (Arbutin), yemwenso amadziwika kuti arbutin, mankhwala dzina 4-hydroxyphenyl-D-glucopyranoside, wachibale molekyulu kulemera ndi 272.25, ndi glycoside zachilengedwe kuchokera zomera zobiriwira, ambiri amaundana-kuyanika zomera, monga tirigu, peyala, rhododendraceae zipatso zolemera. mu solves, makhiristo oyera aciculate kapena ufa, Amasungunuka m'madzi otentha, methanol, ethanol ndi propylene glycol, propylene glycol, insoluble mu ether, chloroform, petroleum ether ndi zosungunulira zina.
Arbutin imatha kugawidwa mumtundu wa α ndi mtundu wa β molingana ndi mawonekedwe osiyanasiyana. α-arbutin amatchedwa 4-hydroxyphenyl-α-D-glucopyranoside, ndipo β-arbutin amatchedwa 4-hydroxyphenyl-β-D-glucopyranoside. Alpha-arbutin ndi isomer yosiyana ya β-arbutin, ndipo chomangira chake cha glucoside chimakhala chosiyana ndi cha β-arbutin (onani chithunzi).
