Niacinamide ndi ufa woyera ngati singano wa kristalo kapena kristalo, wopanda fungo kapena wonunkhira pang'ono, wokhala ndi kukoma kowawa pang'ono. Kuchuluka kwake ndi 1.4, ndipo malo ake osungunuka ndi 129-131℃. 1g ya mankhwalawa imatha kusungunuka mu 1mL ya madzi, 1.5mL ya ethanol, kapena 10mL ya glycerol, koma osati mu ether. pH ya yankho lamadzi la 10% ndi 6.5-7.5. Ili ndi hygroscopicity yofooka. Ndi yokhazikika, yolimbana ndi ma acid, alkali, ndi kutentha kwambiri. Ndi yokhazikika ku kuwala ndi kutentha mumlengalenga wouma, koma ikatenthedwa mu yankho la alkaline kapena acidic, imapanga nicotinic acid. LD50 ya pakamwa mwa makoswe ndi 2.5-3.5g/kg, ndipo mtengo wa ADI sunatchulidwe mwachindunji (ECC, 1990).

Kagwiritsidwe Ntchito
- Kunyowetsa, kulamulira mafuta, ndi kuchepetsa madontho akuda: Niacinamide imatha kuchepetsa bwino kutayika kwa madzi a transepidermal. Ngakhale kuti mphamvu yake ikagwiritsidwa ntchito yokha siili yabwino ngati ya hyaluronic acid ndi glycerin, mphamvu yake ikagwiritsidwa ntchito pamodzi ndi 1+1>2; niacinamide imatha kutonthoza ma sebaceous glands "ogwira ntchito mopitirira muyeso", motero imachepetsa mafuta ndikuchepetsa madontho akuda ndi ziphuphu.
- Mphamvu yabwino yolimbana ndi makwinya: Mphamvu yabwino yolimbana ndi makwinya ya niacinamide ili m'kuthekera kwake kuyambitsa ATP, kupereka mphamvu ku ma keratinocyte, kuwonjezera kapangidwe ka collagen, komanso ili ndi mphamvu yabwino yogwirizana, yomwe ingagwiritsidwe ntchito limodzi ndi zosakaniza zina zotsutsana ndi makwinya.
- Mphamvu yabwino yothandizira kuteteza ku dzuwa: Kuwonongeka komwe kumachitika chifukwa cha kuwala kwa ultraviolet ku thupi la munthu sikuti kungotentha khungu kokha, komanso kuletsa chitetezo cha mthupi (Chemicalbook) komanso khansa ya pakhungu. Kafukufuku wambiri kunyumba ndi kunja kwa dziko lapansi wasonyeza kuti niacinamide imatha kuchepetsa bwino kufalikira kwa kuwala kwa dzuwa pakhungu panthawi ya kuwala kwa ultraviolet.
- Kufatsa kwabwino: Poyerekeza ndi zosakaniza monga vitamini C ndi resorcinol derivatives, niacinamide ndi yofatsa kwambiri ndipo ingagwiritsidwe ntchito ndi anthu amitundu yosiyanasiyana ya khungu. Komabe, chisamaliro chiyenera kuperekedwabe pa kulekerera khungu. Mwachitsanzo, The Ordinary Whitening Essence yokhala ndi kuchuluka kwa niacinamide 10% ikadali ndi kuyabwa kwina. Chifukwa chake, ndibwino kuchita mayeso oletsa khungu musanagwiritse ntchito. Igwiritseni ntchito pokhapokha mutatsimikizira kulekerera, ndipo nthawi yomweyo, samalani kuti musagwiritse ntchito ndi zinthu zokhala ndi asidi monga salicylic acid ndi zipatso acid kuti mupewe kuyabwa kwambiri pakhungu.
Chochokera ku amide chochokera ku vitamini B3 ndi PARP inhibitor
Mankhwala a Vitamini amagwira ntchito m'thupi ndipo amagwiritsidwa ntchito popewa ndi kuchiza matenda ena a pellagra ndi kusowa kwa niacin.
Niacinamide imasungunuka bwino m'madzi kuposa niacin, koma imapanga mosavuta mavitamini C ndi ma clumps. Mlingo wake ndi 30-80mg/kg. Ikagwiritsidwa ntchito mu zinthu zosamalira khungu, imatha kuteteza khungu losalimba, kusunga thanzi la maselo a khungu, komanso kulimbikitsa kuyera kwa khungu. Ikagwiritsidwa ntchito posamalira tsitsi, imatha kulimbikitsa kuyenda kwa magazi m'mutu, kusunga ma follicle a tsitsi kukhala athanzi, kulimbikitsa kukula kwa tsitsi, komanso kupewa kutaya tsitsi.
Kulongedza ndi Kutumiza
25KG/Drum kapena malinga ndi zomwe makasitomala amafuna.
Ndi katundu wamba ndipo amatha kutumizidwa kudzera m'nyanja ndi mlengalenga
Sungani ndi kusunga
Nthawi yosungiramo zinthu: Miyezi 24 kuyambira tsiku lopangidwa m'maphukusi oyambirira osatsegulidwa, osungidwa pamalo ozizira komanso ouma, kutali ndi dzuwa, madzi.
Nyumba yosungiramo zinthu zopumira mpweya, Youma pang'ono, Yosiyana ndi ma oxidants, ma acid.
