Hoʻohana
ʻArbutinNo nā hui hydroquinone glycoside. ʻO kona inoa kemika ʻo 4-Hydroquinone-alpha-D-glucopyranoside. Loaʻa ia i nā mea kanu e like me ka bearberry a me ka bilberry, a he mea hana keʻokeʻo kūlohelohe hou ia me ka ʻole o ka huhū, ʻaʻohe allergy a me ka hoʻokūkū ikaika ma Chemicalbook. Aia ʻelua mau hui hana kūkulu a me ka hana i loko o ke ʻano molekala o ka arbutin: ʻo kekahi ke koena glucose, a ʻo kekahi ka hui phenolic hydroxyl. Aia ʻo Alpha-arbutin i ke ʻano kino o ka pauka keʻokeʻo a hina māmā a hiki ke hoʻoheheʻe ʻia i ka wai a me ka ethanol.
ʻAlepa-arbutinHe hopena maikaʻi kona i ka hoʻōla ʻana i nā ʻeha i hoʻokumu ʻia e nā kuni ultraviolet, a he hopena anti-inflammatory maikaʻi, hoʻoponopono a me ka hoʻokeʻokeʻo. Hiki iā ia ke kāohi i ka hana ʻana a me ka waiho ʻana o ka melanin a wehe i nā kiko makahiki a me nā freckles.
ʻO ke ʻano hoʻokeʻokeʻo o ka alpha-arbutin, ʻo ia ke kāohi pololei i ka hana o ka tyrosinase, a laila e hōʻemi ana i ka hana ʻana o ka melanin, ma mua o ka hoʻokō ʻana i ke kumu o ka hōʻemi ʻana i ka hana ʻana o ka melanin ma ke kāohi ʻana i ka ulu ʻana o nā cell a i ʻole ka hōʻike ʻana o ka gene tyrosinase. ʻOiai ʻo alpha-arbutin kahi mea hana hoʻokeʻokeʻo ʻoi aku ka maikaʻi a me ka palekana, ua hoʻohana mua nā ʻoihana hoʻonaninani ma ka home a ma waho i ka alpha-arbutin ma kahi o ka beta-arbutin ma ke ʻano he mea hoʻohui hoʻokeʻokeʻo. He mea kemika ʻo Alpha-arbutin. E like me ka arbutin, hiki i ka alpha-arbutin ke kāohi i ka hana ʻana a me ka waiho ʻana o ka melanin a wehe i nā kiko makahiki a me nā freckles. Ua hōʻike ʻia nā haʻawina e hiki i ka alpha-arbutin ke kāohi i ka hana o ka tyrosinase ma nā ʻano haʻahaʻa haʻahaʻa, a ʻoi aku ka maikaʻi o kona hopena inhibitory ma ka tyrosinase ma mua o ka arbutin. Hiki ke hoʻohana ʻia ʻo Alpha-arbutin ma ke ʻano he mea hoʻokeʻokeʻo i nā mea hoʻonaninani.
ʻŌpala a me ka Hoʻouna ʻana
25KG/Drum a i ʻole e like me nā koi a ka mea kūʻai aku.
No nā waiwai maʻamau a hiki ke hāʻawi ma ke kai a me ka lewa
Mālama a me ka mālama ʻana
Ola papa: 24 mahina mai ka lā i hana ʻia ai i loko o ka pahu i wehe ʻole ʻia mua i mālama ʻia i kahi maloʻo a me kahi anuanu, mai ka lā pololei, ka wai.
Hale kūʻai ea, hoʻomaloʻo wela haʻahaʻa, hoʻokaʻawale ʻia mai nā mea hoʻomake a me nā waikawa.
