Ingabe I-Arbutin Ifanele Ukusetshenziswa Kwasemini

I-Arbutin, eyaziwa nangokuthi i-myricetin, iyisithako esisebenzayo esenza sibe mhlophe esikhumbeni esihlanganisa imiqondo "eluhlaza", "iphephile", "esebenza kahle" ngoba isuka ezitshalweni eziluhlaza zemvelo. I-Arbutin iyi-ejenti yokwenza mhlophe efanelekile yezimonyo ezimhlophe, enama-isomer amabili optical, okungukuthi α "Futhi" "uhlobo, olunomsebenzi webhayoloji luyi-" "isomer." ". Kuyimpushana emhlophe kancane ephuzi emazingeni okushisa ekamelo, encibilika kalula emanzini, futhi yengezwa emikhiqizweni eminingi emhlophe nokulungisa.

I-Arbutin powder ingenye yezithako ezimhlophe eziphephe kakhulu nezisebenzayo njengamanje ezidume phesheya, futhi iphinde ibe mhlophe esikhumbeni esincintisana kakhulu nokususa ama-freckle ejenti esebenzayo ekhulwini lama-21. Kwezimonyo, ingakwazi ukwenza mhlophe futhi isuse amabala esikhumbeni, iphele kancane kancane futhi isuse ama-freckles, i-chloasma, i-melanosis, induna, namachashaza obudala. Ukuphepha okuphezulu, akukho ukucasuka, ukuzwela, neminye imiphumela emibi. Ukuze kuzinziswe ukusebenza, inani elifanele lama-antioxidants afana ne-sodium bisulfite kanye ne-vitamin E ngokuvamile liyengezwa ukuze kuzuzwe ukumhlophe okungcono, ukususwa kwama-freckle, ukuthambisa, ukuthambisa, ukususwa kwemibimbi, kanye nemiphumela yokulwa nokuvuvukala. Ingasetshenziselwa ukuqeda ububomvu nokuvuvukala, ikhuthaze ukuphulukiswa kwesilonda ngaphandle kokushiya izibazi, futhi ivimbele ukwakheka kwe-dandruff.

I-Arbutin powder inezakhiwo ezimbili: i-alpha arbutin powder kanye ne-beta arbutin powder.

(1). Imithombo ye-α- Arbutin kanye ne-β- arbutin ihluke ngokuphelele.

I-β- I-Arbutin ingakhishwa ezitshalweni ngokusebenzisa isiko lamaseli kanye nokuhlanganiswa kokwenziwa, ukuguqulwa kwe-enzyme, nokukhipha izitshalo.

I-α- I-Arbutin ngokuvamile ingabhekana nokusabela kokudluliswa kukashukela kuphela ngama-enzyme ama-microorganisms ahlukene, okuvumela i-molecule eyodwa ye-glucose ne-molecule eyodwa ye-hydroquinone ukuthi ihlangane yakhe i-α-Arbutin eyodwa. Ukuzinza okuphezulu, ukusebenza kahle, nokuphepha β- Arbutin.

(2). α- Intengo ye-arbutin ingu-β- Cishe izikhathi eziyi-8 kune-arbutin.

(3). α- Umthelela omhlophe we-arbutin ngu-β- Izikhathi ezingaphezu kweziyi-15 kune-arbutin.

(4). I-α- I-Arbutin inomphumela onamandla wokuvimbela emsebenzini we-tyrosinase.

(5). I-α Ursolin inokuqina okungcono, i-α Arbutin ayiboli ekushiseni okuphezulu kwe-100 ° C; I-β Arbutin ibola kancane ngaphezu kuka-60 ° C.

(6). I-α- I-Arbutin ayizwani nezithombe futhi ingasetshenziswa phakathi nosuku.

(7). I-α- I-Arbutin ayikho emvelweni futhi ingatholwa kuphela ngokuvutshelwa.

(8). I-β- Arbutin isetshenziswe emakethe isikhathi eside, ngakho-ke i-arbutin evame ukusetshenziswa yi-β- Arbutin esikhundleni se-α- Arbutin.

I-Arbutin yehlisa ukukhiqizwa kwe-melanin ngokuvimbela umsebenzi we-enzyme i-tyrosinase ekhiqiza i-melanin, futhi indlela yokusebenza kwayo ifana neyesidakamizwa esimhlophe i-hydroquinone. ingezwe ngokukhululekile emikhiqizweni yesondlo enomkhawulo wokuhlushwa ongafika ku-7%.

I-molecule esebenzayo ye-arbutin ingangena kungqimba lwe-basal ukuze isuswe indawo ejulile, futhi inomphumela oqinile wokwelapha ku-chloasma, amabala amnyama, ukushiswa yilanga, kanye nemibala esala ngenxa yokungezwani nezidakamizwa. Kodwa-ke, uma ukugxila kuphansi kakhulu, ukuphikelela komphumela wawo kuzoba buthaka. Ngakho-ke, ukugxila kuka-5% kuyindlela ephephile futhi esebenza kahle kakhulu yokugxilisa ukususwa kwamabala, futhi ukugxila okungama-5% kuyashesha kunovithamini C wokususwa kwamabala. Ngaphezu kwalokho, ukuphikelela kokususwa kwendawo kuzinzile, futhi akunawo umphumela ovuselelayo esikhumbeni.

Ngemva kokumuncwa isikhumba, i-arbutin izoncishiswa ibe yi-hydroquinone, okubangele ukuthi abanye abantu bangabaze ukuphepha kwe-arbutin futhi bakholelwa ukuthi i-arbutin isenethuba lokukhiqiza imiphumela emibi efana ne-hydroquinone. Isitatimende esizwakala kakhulu ukuthi "imikhiqizo yesondlo equkethe i-arbutin akufanele isetshenziswe emini, ngaphandle kwalokho ngeke ibe mhlophe futhi ibe mnyama.".

Ukuhlola kubonise ukuthi i-arbutin kuphela enokugxila okudlula u-7% okungenzeka ibe ne-photosensitive, ngakho-ke u-7% uwumkhawulo wokuphepha. Ukwengezwa kwezithako emikhiqizweni yesondlo kunemithetho ecacile, futhi umkhawulo omkhulu wokuhlushwa ngu-7%. Ngaphakathi kwalolu hlu lokuhlushwa, i-arbutin ayanele ukukhiqiza i-photosensitivity, futhi akudingekile ukuyisebenzisa endaweni emnyama. Imuncwa esikhumbeni futhi iboliswe ukukhanya, izoncishiswa ibe yi-hydroquinone, ikhiqize umphumela omhlophe.
