Kina Nicotinamide (Niacinamide) mea hana
Nicotinamide Introduction:
INCI | Molekula | MW |
Nicotinamide, Pyridine-3-Carboxyamide | C6H6N2O | 122.13 |
Solubility: Hiki ke hoʻoheheʻe ʻia i ka wai a me ka waiʻona, hiki ke hoʻoheheʻe ʻia i ka glycerin
ʻO ka Niacinamide a i ʻole nicotinamide (NAM) he ʻano o ka huaora B3 i loaʻa i ka meaʻai a hoʻohana ʻia ma ke ʻano he meaʻai a me ka lāʻau lapaʻau.Ma ke ʻano he mea hoʻohui, hoʻohana ʻia e ka waha e pale a mālama i ka pellagra (niacin deficiency).ʻOiai hiki ke hoʻohana ʻia ka waikawa nicotinic (niacin) no kēia kumu, loaʻa i ka niacinamide ka pōmaikaʻi o ka ʻole o ka hoʻoulu ʻana i ka ʻili.Ma ke ʻano he cream, hoʻohana ʻia ia e mālama i ka haki.He vitamina hiki ke hoʻoheheʻe ʻia i ka wai.
He liʻiliʻi nā hopena ʻaoʻao.I ka nui o ka nui, hiki mai ka pilikia o ka ate.He palekana ka nui maʻamau no ka hoʻohana ʻana i ka wā hāpai.Aia ʻo Niacinamide i ka ʻohana huaola B o nā lāʻau lapaʻau, ʻo ia hoʻi ka paʻakikī o ka huaora B3.He amide ia o ka waikawa nicotinic.ʻO nā meaʻai i loaʻa i ka niacinamide ka hū, ka ʻiʻo, ka waiū, a me nā lau ʻōmaʻomaʻo.
Ua ʻike ʻia ʻo Niacinamide ma waena o 1935 a me 1937. Aia ia ma ka papa inoa o nā lāʻau koʻikoʻi o ka World Health Organization.Loaʻa ka Niacinamide ma ke ʻano he lāʻau lapaʻau maʻamau a ma luna o ke kauā.Ma ke kālepa, hana ʻia ka niacinamide mai ka waikawa nicotinic (niacin) a i ʻole nicotinonitrile.I kekahi mau ʻāina, ua hoʻohui ʻia ka niacinamide iā lākou.
NicotinamideNoi:
Aia ia i ka Vitamin B, e komo ana i ka metabolism i loko o ke kino, hiki ke hoʻohana ʻia e pale i ka pellagra a i ʻole nā maʻi defection niacin.Hoʻohana ʻia no ka lāʻau lapaʻau, meaʻai additiKe hana nei kēia huahana penei:
ʻO ka mea mua, hohonu ka melanin i loko o ka ʻili o ka melanin cell, akā i kēia manawa, ʻo ia hoʻi i loko, ua hoʻololi ʻia nā tentacles i nā keratin a puni, hiki i ka nicotinamide ke hoʻopilikia i ka hoʻoili ʻana o ka melanin, hana melanin i melanocyte noho i loko ʻaʻole e hele mai. i waho, no laila ʻaʻole e hoʻomau i ka hana ʻana i nā melanin melanin cell, ʻo ka lua, ʻaʻole ʻike ʻia ka melanin e ka maka o ke kanaka ma ka ʻili o ka ʻili, i mea e loaʻa ai ka hopena keʻokeʻo.
ʻO ka lua, ua hōʻike ʻo niacinamide i ka hopena maikaʻi o ka saccharification, ʻoi aku ma hope o 2015, ʻo ka huaʻōlelo "ka saccharification noiʻi hohonu loa, nui nā maʻi physiological i hōʻike ʻia me ka saccharification (maillard reaction), nā mea i hana ʻia e ka saccharification he brown, hiki ke ʻae. ʻeleʻele ka ʻili, no laila kōkua pū ka mash resistance i ka whitening.ves, feed additives, cosmetic, etc.
I loko o kahi hoʻokolohua hoʻomalu ʻia o 20 mau kumuhana, ʻoi aku ka maikaʻi o nā ʻaʻahu intermittent o nicotinamide ma kahi haʻahaʻa haʻahaʻa (0.2%) i ka hoʻohaʻahaʻa ʻana i ka immunosuppression o ka ʻili i hoʻoulu ʻia e ka radiation UV haiki e like me ka lā.He kūpono ka 0.2% o ka hoʻopaʻa ʻana, a hoʻohana maʻamau mākou i ka nicotinamide e pili ana i nā huahana mālama ʻili ma luna o 2%, ʻoi aku ka maikaʻi o 4% ~ 5%.No laila e hoʻopili i ka nicotinamide extract ma mua o ka hoʻohana ʻana i ka sunscren.
