China Nicotinamide (Niacinamide) Abavelisi
Intshayelelo yeNicotinamide:
| INCI | Imolekyula | MW |
| INicotinamide, iPyridine-3-Carboxyamide | I-C6H6N2O | 122.13 |
Ukunyibilika: Inyibilika ngokukhululekileyo emanzini nasetywaleni, inyibilika kwi-glycerin
I-Niacinamide okanye i-nicotinamide (NAM) luhlobo lwevithamin B3 efumaneka ekutyeni kwaye isetyenziswa njengesongezelelo sokutya kunye namayeza.Njengesongezelelo, isetyenziswa ngomlomo ukuthintela kunye nokunyanga i-pellagra (ukunqongophala kweniacin).Ngelixa i-nicotinic acid (niacin) inokusetyenziselwa le njongo, i-niacinamide inenzuzo yokungabangeli ukugungxulwa kwesikhumba.Njenge-cream, isetyenziselwa ukunyanga i-acne.Yivithamini enyibilikayo emanzini.
Iziphumo ebezingalindelekanga zincinci.Kwidosi ephezulu iingxaki zesibindi zisenokwenzeka.Izixa eziqhelekileyo zikhuselekile ukuba zisetyenziswe ngexesha lokukhulelwa.I-Niacinamide ikusapho lwe-vitamin B kusapho lwamayeza, ngakumbi i-vitamin B3 complex.Yi-amide ye-nicotinic acid.Ukutya okuneniacinamide kubandakanya igwele, inyama, ubisi, kunye nemifuno eluhlaza.
I-Niacinamide yafunyanwa phakathi kuka-1935 kunye no-1937. Ikuluhlu lwaMayeza ayimfuneko kuMbutho wezeMpilo weHlabathi.I-Niacinamide iyafumaneka njengeyeza elenziwe lafana nalawo aveliswe ngumenzi nakwikhawuntara.Urhwebo, i-niacinamide yenziwe nge-nicotinic acid (niacin) okanye i-nicotinonitrile.Kumazwe amaninzi iinkozo zongezwa iniacinamide kuzo.
INicotinamideIsicelo:
I-Vitamin B, ethatha inxaxheba kwi-metabolism emzimbeni, ingasetyenziselwa ukukhusela i-pellagra okanye esinye isifo se-niacin defection.Isetyenziselwa ikhemesti, i-additi yokutyaLe mveliso isebenza ngolu hlobo lulandelayo:
Okokuqala, i-melanin inzulu eluswini lweseli melanin, kodwa ngeli xesha, nayo ngaphakathi, kamva ithentacles idluliselwa kwiiseli keratin ezijikelezileyo, nicotinamide unokuphazamisana nokudluliselwa melanin, ukwenza melanin iye melanocyte ukuhlala ngaphakathi ukuba angezi. ngaphandle, ngoko akayi kuqhubeka ukuvelisa iiseli melanin melanin, Okwesibini, melanin akayi kubonwa ngeliso lomntu phezu kwesikhumba, ukuze kuzuzwe isiphumo mhlophe.
Okwesibini, i-niacinamide ingqina ukuba inesiphumo esihle se-saccharification, ngakumbi emva kwe-2015, igama elithi "i-saccharification yophando olunzulu kakhulu, izifo ezininzi ze-physiological zibonise ukuba kunye ne-saccharification (i-maillard reaction), izinto eziveliswa yi-saccharification zimdaka, zinokuvumela ulusu lubonakala lumnyama, ngoko ke ukuxhathisa i-mash kunceda kwakhona kwi-whitening.ves, izongezo zokutya, izimonyo, njl.
Kulingo olulawulwayo lwezifundo ze-20, iingubo eziphindaphindiweyo ze-nicotinamide kwi-concentration ephantsi (0.2%) nazo ziphumelele ekunciphiseni ukugonywa kwesikhumba okubangelwa yimisebe ye-UV emincinci efana nokukhanya kwelanga.I-0.2% yogxininiso lusebenza kakuhle, kwaye ngokuqhelekileyo sisebenzisa i-nicotinamide esekelwe kwiimveliso zokunakekelwa kwesikhumba ukugxininiswa ngokubanzi kungaphezulu kwe-2%, i-concentration engcono ye-4% ~ 5%.Ke sebenzisa isicatshulwa se-nicotinamide ngaphambi kokufaka i-sunscren.
