Umsebenzi

U-Arbutin unomphumela wokukhanyisa isikhumba. Ingangena ngokushesha esikhunjeni ngaphandle kokuthinta amaseli esikhumba. Ingahlanganisa ne-tyrosine ebangela ukukhiqizwa kwe-melanin, ukuvimba ngempumelelo umsebenzi we-tyrosine nokwakhiwa kuka-melanin, futhi kusheshise ukubola nokuqedwa kwe-melanin. Ngaphezu kwalokho, i-Arbutin nayo ingavikela isikhumba kusuka kuma-radicals wamahhala futhi ine-hydrophility enhle

Ukupakisha nokuthumela

I-vacuum igcwele ezikhwameni ze-aluminium foil kanye nezikhwama zepulasitiki ezivaliwe, i-1kg ngayinye. I-Arbutin i-hygroscopic, sicela ugcine endaweni epholile neyomile.

Kungokwezimpahla ezijwayelekile futhi kungaletha ulwandle noma umoya
