IArbutin, ekwabizwa ngokuba yiArbutin, yikristale emhlophe eneacicular okanye umgubo. Amagqabi athathwe kwisiqhamo sebhere anokuthintela ukubunjwa kwe-melanin ngokuthintela umsebenzi weTyrosinase emzimbeni, ngaloo ndlela unciphisa ukubekwa kwebala lesikhumba, ukususa amabala ombala kunye namabala, kunye nokuba neziphumo ze-bactericidal kunye ne-anti-inflammatory. Ikakhulu isetyenziselwa ukulungiswa kwezithambiso eziphezulu.
Igama lesiNgesi: Arbutin
IArbutin yahlulwe yaba yi-β- Ursolin (Beta arbutin) kunye ne-α-Arbutin (alpha arbutin), α-Arbutin
Umahluko phakathi kwezi zimbini:
Uninzi lwe-arbutin kwimarikeb- Arbutin, α- Bambalwa kuphela abavelisi abavelisa i-arbutin, kwaye ixabiso limalunga namaxesha e-8 angaphambili. Kodwa umphumo wobumhlophe ungaphezulu kwamaxesha e-15 kuneyangaphambili.
Umahluko omkhulu kwiipropati zomzimba phakathi kwezi zimbini kukujikeleza kwazo: α- Umxholo we-arbutin ujikeleze i-180 degrees, ngelixa i-β-Arbutin ijikeleze -60.
I-Arbutin yinto yendalo esebenzayo evela kwi-Viridiplantae. Iyinxalenye ye-bleaching yesikhumba edibanisa "i-Viridiplantae, ukhuseleko kunye nokuthembeka" kunye "ne-decolorization esebenzayo". Inokungena ngokukhawuleza eluswini, ithintele ngokufanelekileyo umsebenzi weTyrosinase eluswini, ithintele ukwakheka kwemelanin, kwaye ikhawulezise ukubola kunye nokukhutshelwa kwe-melanin ngokuzidibanisa ngokuthe ngqo ne-tyrosinase ngaphandle kokuchaphazela ukugcwala kweseli, inokunciphisa ukubola. Ukubekwa kwebala lolusu, susa amabala ombala kunye namabala, kwaye ayinayo ityhefu, iyacaphuka, iyala kunye nezinye iziphumo ebezingalindelekanga kwiChromatophore. Kwangaxeshanye, inokubulala iibhaktheriya kwaye inciphise ukudumba. Sesona sithako sikhuselekileyo nesisebenzayo sokwenza mhlophe sithandwa ngoku, kwaye sikwayindlela efanelekileyo yokwenza mhlophe kunye nokususa amabala asebenzayo kwinkulungwane yama-21.
Uyongeza njani iArbutin kwindlela yakho yokuKhathalela ulusu
Ungasebenzisa ngokukhuselekileyo i-arbutin ekugxininiseni ukuya kuthi ga kwi-2 yeepesenti kwiikhrimu zobuso kunye ne-0.5 yeepesenti kwizithambiso zomzimba, u-Chiu uthi, esongeza ukuba isithako "sikhuselekile kwaye sinobundlongondlongo xa sithelekiswa ne-hydroquinone." (Ngelixa i-hydroquinone ekugxininiseni okungaphezulu kwepesenti enye iye yavalwa kwiimveliso zokuthambisa kwi-EU, Japan, Australia, kunye namazwe aliqela e-Afrika, i-arbutin ikhuselekile kwezi zigxinaniso zingasentla kuba i-hydroquinone ikhutshwa kancinci kwaye ulusu aluvezwa kakhulu. ngayo nangaliphi na ixesha, uyacacisa.)
IArbutin sisithako esikhanyisa ulusu esijolise kumabala amnyama, i-hyperpigmentation, kunye neziva. Ngelixa inamandla amancinci xa ithelekiswa ne-hydroquinone, ineprofayili yokhuseleko eyomeleleyo kunye neengozi ezimbalwa zeziphumo ebezingalindelekanga.
