Ikoreshwa
Arbutin ifite ingaruka zo kumurika uruhu.Irashobora kwinjira vuba mu ruhu itagize ingaruka ku ngirangingo z'uruhu.Irashobora guhuza na tirozine itera umusaruro wa melanin, igahagarika neza ibikorwa bya tirozine no gukora melanine, kandi ikihutisha kubora no kurandura melanine.Byongeye kandi, arbutine irashobora kandi kurinda uruhu radicals yubusa kandi ifite hydrophilicity nziza
Gupakira no kohereza
Vacuum ipakiye mumifuka ya aluminiyumu hamwe nu mifuka ya pulasitike, 1kg imwe.Arbutin ni hygroscopique, nyamuneka ubike ahantu hakonje kandi humye.
Biri mubicuruzwa bisanzwe kandi birashobora gutangwa ninyanja cyangwa ikirere
kubika no kubika
Agaciro: 2years
Guhumeka ubushyuhe buke;hamwe na aside, umunyu wa ammonia ubitswe ukwe
Ubushobozi: 200MT ku mwaka, ubu twagura umurongo w'umusaruro.
