Ukusetshenziswa

I-Arbutin inomphumela wokukhanyisa isikhumba.Ingangena ngokushesha esikhumbeni ngaphandle kokuthinta amangqamuzana esikhumba.Ingahlangana ne-tyrosine ebangela ukukhiqizwa kwe-melanin, ivimbele ngempumelelo umsebenzi we-tyrosine nokwakheka kwe-melanin, futhi isheshise ukubola nokuqedwa kwe-melanin.Ngaphezu kwalokho, i-arbutin ingavikela isikhumba kuma-radicals mahhala futhi ine-hydrophilicity enhle

Ukupakisha kanye Nokuthumela

I-vacuum epakishwe ezikhwameni ze-aluminium foil kanye nezikhwama zepulasitiki ezinomugqa, 1kg ngayinye.I-Arbutin i-hygroscopic, sicela uyigcine endaweni epholile neyomile.

Kungeyezimpahla ezijwayelekile futhi ingadiliva ngolwandle noma ngomoya
