Hoʻohana
ʻO ka hopena o Arbutin ka hoʻomālamalama ʻana i ka ʻili. Hiki iā ia ke komo koke i loko o ka ʻili me ka ʻole o ka hoʻopilikia ʻana i nā ʻili. Hiki iā ia ke hui pū me ka tyrosine e hoʻoulu ai i ka hana melanin, e ālai pono i ka hana o ka tyrosine a me ke kūkulu ʻia ʻana o ka melanin, a e hoʻolalelale i ka palaho a me ka hoʻopau ʻana o ka melanin. Eia kekahi, hiki i ka arbutin ke pale i ka ʻili mai nā radical manuahi a he hydrophilicity maikaʻi.
ʻŌpala a me ka Hoʻouna ʻana
Hoʻopaʻa ʻia i loko o nā ʻeke pepa alumini a me nā ʻeke palaki i uhi ʻia i ka vacuum, 1kg kēlā me kēia. He hygroscopic ʻo Arbutin, e ʻoluʻolu e mālama i kahi maloʻo a me kahi anuanu.
No nā waiwai maʻamau a hiki ke hāʻawi ma ke kai a i ʻole ka lewa
mālama a me ka hoʻopaʻa ʻana
Mana: 2 mau makahiki
Hoʻomaloʻo ʻana i ka mahana haʻahaʻa me ka ea; me ka waikawa, ka paʻakai ammonia i mālama ʻokoʻa ʻia
Ka mana: 200MT i kēlā me kēia makahiki, ke hoʻonui nei mākou i kā mākou laina hana.

Q: Inā hiki iā ʻoe ke ʻae i ka hoʻopili kūikawā no Arbutin CAS 497-76-7?
R: ʻAe, hiki iā mākou ke hoʻonohonoho i ka hoʻopili ʻana e like me ke koi a ka mea kūʻai aku.
Q: Hiki ke hoʻohana i ka Arbutin CAS 497-76-7 ma nā huahana hoʻonani?
