INicotinamide
INicotinamide
1. Intshayelelo:
| INCI | Imolekyuli | MW |
| INicotinamide, iPyridine-3-Carboxyamide | I-C6H6N2O | 122.13 |
Ukunyibilika: Inyibilika ngokukhululekileyo emanzini nasetywaleni, inyibilika kwi-glycerin
2.Isicelo:
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 inefuthe elihle le-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 zintsundu, 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-sunscreen
