3-O-Ethyl-L-ascorbic acidLoaʻa iā ia nā waiwai ʻelua o ka aila hydrophilic a paʻa loa ke kemika. ʻO ka 3-O-Ethyl-L-ascorbic acid, ka helu cas 86404-04-8, he waiwai oleophilic a hydrophilic ma ke ʻano he huaora C derivative, e hoʻolōʻihi i kona laulā o ka noi, ʻoi aku i ka kemika o kēlā me kēia lā.

He mea paʻakikī ke komo ʻana o ka huaora C maʻamau e ka ʻili a he haʻahaʻa ka bioavailability. ʻO nā waiwai hydrophilic a me lipophilic o 3-O-Ethyl L-ascorbic acid e maʻalahi ke komo i ka stratum corneum a komo i ka dermis. Ma hope o ke komo ʻana i ka ʻili, ua maʻalahi ka 3-O-Ethyl L-Ascorbic acid e nā enzyme biological e pāʻani i ke ʻano o ka vitamina C, a laila e hoʻomaikaʻi ai i kona bioavailability.

Eia kekahi, 3-O-Ethyl-L-ascorbic acid he mea maʻamau ka huaora C, e hōʻike ana i ke kūpaʻa kiʻekiʻe e hōʻoia i ka loaʻa o VC, a loaʻa maoli ka hopena o ka whitening a me ka freckling.

Pono: 3-O-Ethyl-L-ascorbic acid he keʻokeʻo a keʻokeʻo paha ka pauka crystalline i ka helehelena. ʻO ia kekahi o nā derivatives maikaʻi loa o ka vitamina C a hiki i kēia lā. ʻAʻole paʻa kemika wale nō, akā, he ascorbic acid derivative ʻaʻole hiki ke hoʻololi maʻalahi ma hope o ke komo ʻana i ka ʻili. Hoʻopili ʻia ia ma ke ʻano like me ka vitamina C i loko o ke kino, no laila e hana ana i kahi hopena maikaʻi o ka ascorbic acid.

Mechanism o ka hana: 3-O-Ethyl-L-ascorbic acid inhibits tyrosinase activity and the formation of melanin by reaching the basal layer through the stratum corneum of the skin, hoemi melanin to colorless, effective in whitening and remove freckles. Hiki i ka 3-O-Ethyl-L-ascorbic acid ke komo pololei i ka synthesis o ka collagen ma hope o ke komo ʻana i ka dermis, kahi e hoʻonui ai i ka collagen, a laila e hoʻopiha ai ka ʻili a elastic.

Nā hana nui:

(1) Hoʻopaʻa i ka hana tyrosinase a hoʻopaʻa i ka hana melanin; Hoʻemi i ka melanin, hoʻomaʻemaʻe i nā kiko a keʻokeʻo.

(2) He hopena antioxidant ikaika, hoʻopau maikaʻi i nā radical manuahi.

(3) Ke kūpaʻa maikaʻi, ke kū'ē māmā, ke kū'ē i ka wela, kaʻakika a me ke kūpaʻa alkali, ke kū'ēʻana o ka ea. ʻO ka bioavailability kiʻekiʻe, ka aila hydrophilic, ka maʻalahi o ka ʻili.

(4) Kāohi i ka ʻili ʻili ma muli o ka lā.

(5) Hoʻoikaika i ka hana collagen a hoʻonui i ka elasticity o ka ʻili.

3-O-Ethyl-L-ascorbic acidLoaʻa iā ia ka hana o ka hoʻoponopono ʻana i ka collagen (me ka hoʻoponopono ʻana i ka haku mele a me ka synthesis), hiki ke hoʻoikaika i ka hoʻokumu ʻana o nā ʻili ʻili a me ka synthesis collagen e like me ka ratio o nā ʻili ʻili a me ka hoʻohana ʻana i ka collagen, i mea e ʻālohilohi ai ka ʻili. Hoʻohana nui ʻia ka Vitamin C ethyl ether i ka hoʻomaʻemaʻe ʻana i ka freckle a me nā huahana mālama ʻili anti-aging, e like me ka lotion, cream, toner, mask, essence a pēlā aku.

Hoʻohana huahana:

Hoʻohana ʻia kēia huahana i nā huahana keʻokeʻo, nā huahana anti-aging, wai, gel, essence, lotion, ʻili mālama ʻili a pēlā aku.

[Manaʻo ʻia] 0.1-2.0%, kūpono i nā huahana keʻokeʻo a me ka wehe ʻana i ka freckle, ka wehe ʻana i ka wrinkle a me nā huahana anti-kahiko.

[Manaʻo ʻia ka hana] ʻoi aku ka maikaʻi o ka hoʻohana ʻana ma lalo o nā kūlana PH3.0-6.0, a ʻo ka hopena keʻokeʻo a me ka freckle ka mea maikaʻi loa.

3-O-ethyl-L-ascorbicHe mea hoʻopaʻa pono paha ka waikawa no nā hāʻina p-hydroxyacetophenone.

Nā hopena o ka vitamin C ethyl ether ma ka ʻili:

Kāohi ʻana i ka hana tyrosinase ma ka hana ʻana i ka Cu2+ a me ka pale ʻana i ka hoʻokumu ʻana o ka melanin;

ʻO ka hoʻomaʻemaʻe maikaʻi loa a me ka wehe ʻana i ka freckle (2% ke hoʻohui ʻia);

ʻO ka ʻāʻī ʻana i hana ʻia e ka māmā, he ikaika antibacterial a me ka hopena anti-inflammatory;

E hoʻomaikaʻi i ka ʻili o ka ʻili, hāʻawi i ka elasticity o ka ʻili;

Hoʻoponopono i ka hana ʻili a hoʻoikaika i ka hana collagen.
