I-Nicotinamide
I-Nicotinamide
1.Isingeniso:
| INCI | I-Molecula | MW |
| I-Nicotinamide, i-Pyridine-3-Carboxyamide | I-C6H6N2O | 122.13 |
Ukunyibilika: Incibilika ngokukhululeka emanzini nasetshwaleni, inyibilika ku-glycerin
2.Uhlelo lokusebenza:
Iyingxenye ye-Vitamin B, ebamba iqhaza ku-metabolism emzimbeni, ingasetshenziswa ukuvimbela i-pellagra noma esinye isifo se-niacin defection.Isetshenziselwa ikhemisi, i-additi yokudlaLo mkhiqizo usebenza kanje:
Okokuqala, i-melanin ijulile esikhumbeni se-melanin cell, kodwa kulokhu, futhi ngaphakathi, kamuva amatende adluliselwa kumaseli e-keratin azungezile, i-nicotinamide ingaphazamisa ukudluliselwa kwe-melanin, yenza i-melanin ibe yi-melanocyte ihlale ngaphakathi ukuze ingafiki. out, ngakho ngeke uqhubeke ukukhiqiza melanin melanin amangqamuzana, Okwesibili, melanin ngeke kubonwe iso lomuntu phezu kwesikhumba, ukuze kuzuzwe umphumela mhlophe.
Okwesibili, i-niacinamide ifakazela ukuthi inomphumela omuhle we-saccharification, ikakhulukazi ngemva kuka-2015, igama elithi "i-saccharification ucwaningo olunzulu kakhulu, izifo eziningi ze-physiological zabonisa ukuthi nge-saccharification (i-maillard reaction), izinto ezikhiqizwa yi-saccharification zinsundu, zingavumela. isikhumba sibukeka simnyama, ngakho ukumelana ne-mash kuyasiza futhi ku-whitening.ves, izithasiselo zokudla, izimonyo, njll.
Esivivinyweni esilawulwayo sezifundo ezingu-20, amajazi aphindelelayo aphindaphindiwe e-nicotinamide ekugxilweni okuphansi (0.2%) nawo aphumelele ekwehliseni ukuvinjelwa kokuzivikela komzimba okubangelwa imisebe ye-UV ene-spectrum emincane elingisa ukukhanya kwelanga.I-0.2% ye-concentration iyasebenza, futhi ngokuvamile sisebenzisa imikhiqizo yokunakekelwa kwesikhumba esekwe ku-nicotinamide ngokuvamile ingaphezu kuka-2%, ukugxiliswa okuhle kakhulu kuka-4% ~ 5%.Ngakho-ke sebenzisa i-nicotinamide ekhishwe ngaphambi kokufaka i-sunscreen
3. Imininingwane:
