Kagwiritsidwe Ntchito
ArbutinIli m'gulu la mankhwala a hydroquinone glycoside. Dzina lake la mankhwala ndi 4-Hydroquinone-alpha-D-glucopyranoside. Imapezeka m'zomera monga bearberry ndi bilberry, ndipo ndi chinthu chatsopano choyera chomwe chimayamba kugwira ntchito popanda kuyabwa, palibe ziwengo komanso chimagwirizana kwambiri ndi Chemicalbook. Pali magulu awiri ogwira ntchito m'mapangidwe a arbutin: limodzi ndi zotsalira za shuga, ndipo lina ndi gulu la phenolic hydroxyl. Alpha-arbutin ili mumkhalidwe wa ufa woyera mpaka imvi wopepuka ndipo imasungunuka pang'ono m'madzi ndi ethanol.
Alpha-arbutinIli ndi mphamvu yabwino yochiritsira zipsera zomwe zimachitika chifukwa cha kupsa kwa ultraviolet, ndipo ili ndi mphamvu yabwino yoletsa kutupa, kukonza ndi kuyeretsa khungu. Imatha kuletsa kupanga ndi kusunga melanin ndikuchotsa mawanga okalamba ndi madontho.
Njira yoyeretsera alpha-arbutin ndikuletsa mwachindunji ntchito ya tyrosinase, motero kuchepetsa kupanga kwa melanin, m'malo mokwaniritsa cholinga chochepetsa kupanga kwa melanin mwa kuletsa kukula kwa maselo kapena kuwonetsa kwa jini ya tyrosinase. Popeza alpha-arbutin ndi chinthu chogwira ntchito bwino komanso chotetezeka choyeretsa, makampani ambiri odzola kunyumba ndi kunja agwiritsa kale ntchito alpha-arbutin m'malo mwa beta-arbutin ngati chowonjezera choyeretsa. Alpha-arbutin ndi mankhwala. Mofanana ndi arbutin, alpha-arbutin imatha kuletsa kupanga ndi kuyika kwa melanin ndikuchotsa mawanga okalamba ndi madontho. Kafukufuku wasonyeza kuti alpha-arbutin imatha kuletsa ntchito ya tyrosinase pamlingo wochepa, ndipo mphamvu yake yoletsa tyrosinase ndi yabwino kuposa ya arbutin. Alpha-arbutin ingagwiritsidwe ntchito ngati choyeretsa mu zodzoladzola.
Kulongedza ndi Kutumiza
25KG/Drum kapena malinga ndi zomwe makasitomala amafuna.
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.
