Kusungunuka: Kusungunuka momasuka m'madzi ndi mowa, kusungunuka mu glycerin
Niacinamide kapena nicotinamide (NAM) ndi mtundu wa vitamini B3 womwe umapezeka muzakudya ndipo umagwiritsidwa ntchito ngati chowonjezera chazakudya komanso mankhwala.Monga chowonjezera, chimagwiritsidwa ntchito pakamwa popewa ndi kuchiza pellagra (kusowa kwa niacin).Ngakhale kuti nicotinic acid (niacin) angagwiritsidwe ntchito pa izi, niacinamide ili ndi ubwino wosapangitsa khungu kusungunuka.Monga kirimu, amagwiritsidwa ntchito pochiza ziphuphu.Ndi vitamini yosungunuka m'madzi.
Zotsatira zake ndizochepa.Pa mlingo waukulu mavuto a chiwindi akhoza kuchitika.Miyezo yokhazikika ndiyotetezeka kuti igwiritsidwe ntchito pa nthawi yapakati.Niacinamide ali m'gulu lamankhwala la vitamini B, makamaka vitamini B3 zovuta.Ndi amide wa nicotinic acid.Zakudya zomwe zili ndi niacinamide ndi yisiti, nyama, mkaka, ndi masamba obiriwira.
Niacinamide inapezeka pakati pa 1935 ndi 1937. Ili pa Mndandanda wa Mankhwala Ofunika Kwambiri a World Health Organization.Niacinamide imapezeka ngati mankhwala amtundu uliwonse komanso pa kauntala.Mwamalonda, niacinamide amapangidwa kuchokera ku nicotinic acid (niacin) kapena nicotinonitrile.M'mayiko angapo mbewu zimawonjezeredwa ku niacinamide.
Ndi vitamini B, kutenga nawo gawo mu kagayidwe mu thupi, angagwiritsidwe ntchito kupewa pellagra kapena matenda ena niacin defection.Amagwiritsidwa ntchito ku pharmacy, chakudya chowonjezeraChida ichi chimagwira ntchito motere:
Choyamba, melanin kwambiri khungu la melanin selo, koma nthawi ino, komanso mkati, kenako tentacles umasamutsidwa ozungulira maselo keratin, nicotinamide akhoza kusokoneza kulanda melanin, kupanga melanin wakhala melanocyte kukhala mkati kuti asabwere. kunja, kotero sadzapitiriza kutulutsa melanin melanin maselo, Kachiwiri, melanin sadzaona ndi maso a munthu pa khungu pamwamba, kuti tikwaniritse whitening kwenikweni.
Chachiwiri, niacinamide imatsimikizira kuti imakhala ndi zotsatira zabwino za saccharification, makamaka pambuyo pa 2015, mawu akuti "saccharification yozama kwambiri, matenda ambiri a thupi amasonyeza kuti ndi saccharification (maillard reaction), zinthu zopangidwa ndi saccharification ndi zofiirira, zimatha kulola. khungu limawoneka lakuda, kotero kukana phala kumathandizanso kuti whitening.ves, zowonjezera chakudya, zodzoladzola, etc.
M'mayesero olamulidwa a anthu a 20, malaya obwerezabwereza a nicotinamide pamagulu otsika (0.2%) anali othandizanso kuchepetsa chitetezo chamthupi chomwe chimayambitsidwa ndi kuwala kwa UV komwe kumatsanzira kuwala kwa dzuwa.0.2% ya ndende imakhala yothandiza, ndipo nthawi zambiri timagwiritsa ntchito mankhwala osamalira khungu a nicotinamide nthawi zambiri amakhala pamwamba pa 2%, ndende yabwino kwambiri ya 4% ~ 5%.Chifukwa chake perekani nicotinamide musanayambe kugwiritsa ntchito sunscren.
