I-Alpha-Arbutin

Incazelo emfushane:

I-Alpha-Arbutin (4- Hydroxyphenyl-±-D-glucopyranoside) ihlanzekile, inyibilika emanzini, isithako esisebenzayo se-biosynthetic. I-Alpha-Arbutin ivimba i-epidermal melanin synthesis ngokuvimbela i-enzymatic oxidation ye-Tyrosine ne-Dopa. I-Arbutin ibonakala inemiphumela emibi embalwa kune-hydroquinone ekugxilweni okufanayo - mhlawumbe ngenxa yokukhululwa kancane kancane. Kuyindlela ephumelela kakhulu, esheshayo nephephile yokuthuthukisa ukukhazimula kwesikhumba kanye nesikhumba esilinganayo kuzo zonke izinhlobo zesikhumba. I-Alpha-Arbutin iphinda inciphise amabala esibindi futhi ihlangabezane nazo zonke izidingo zomkhiqizo wesimanje ocwebezelayo kanye nowokususa umbala wesikhumba.


  • Igama Lomkhiqizo: I-Alpha-Arbutin
  • INCI Igama: I-Alpha-Arbutin
  • Inombolo ye-CAS: 84380-01-8
  • I-Molecular Formula: I-C12H16O7
  • Imininingwane Yomkhiqizo

    Omaka bomkhiqizo

    I-Alpha I-Arbutin ibonisa i-tyrosinase inhibition ehlaba umxhwele futhi isebenza ngokuphindwe kayisishiyagalolunye kune-Beta-I-Arbutin. Amanani aphansi kakhulu e-IC50 akhombisa amandla we  I-Alpha-Arbutin. Ukusebenza okuvelele kwe-Alphar-Arbutin kungenxa yokuhlobana kwayo okuphelele nendawo esebenzayo ye-tyrosinase.

    I-Alpha-Arbutin inyibilika emanzini futhi ifakwa kalula esigabeni samanzi sokwakheka kwezimonyo. Iqinile ngokumelene ne-hydrolysis njengoba ihlolwe ebangeni le-pH ukusuka ku-3.5 - 6.6. Ukugxilisa ingqondo okuphakanyisiwe: 0.2% uma kwenziwa ngesithuthukisi esisikhiphayo noma sokungena, uma kungenjalo kufika ku-2%.

    Izici Zomkhiqizo:

    • Igama le-INCI (elisebenzayo): Alpha-Arbutin
    • Imiphumela efakazelwe ngokwesayensi ekugxilweni okuphansi
    • Isebenza kakhulu ngo-1.0% kune-Beta-Arbutin nge vivo
      - Isebenza kahle izikhathi eziyisishiyagalolunye kune-Beta-Arbutin ku-vitro
      - Umsebenzi ovelele we-tyrosinase inhibition ku-vitro
    • Isithako esisebenzayo se-biosynthetic esimsulwa kakhulu
    • I-biotechnology ehlobene ne-enzyme esebenza kakhulu
    • Ayiqukethe izinto ezengezwe ngamabomu ezilawulwa/ezifakwe ohlwini njengezilondolozi
    • Ukuthobela i-halal (ingulube notshwala akunaso isitifiketi, akuqinisekisiwe)

    Izinzuzo:

    • Iqinisekisa ithoni yesikhumba esilinganayo ngemva kwenyanga eyodwa kuphela
    • Yehlisa izinga lokushuka kwesikhumba ngemva kokuchayeka kwe-UV
    • Isiza ukunciphisa ukubukeka kwendawo yesibindi

    Arbutin-6

    Iphakheji:

    I-1kg isikhwama se-aluminium foil ngasinye kanye ne-PE bag lining, i-1obags / ibhokisi lebhokisi noma ama-25bags / isigubhu se-fibre
