I-China Nicotinamide (Niacinamide) Abakhiqizi CAS 98-92-0
I-Nicotinamide Isingeniso:
| INCI | I-Molecula | MW |
| I-Nicotinamide, i-Pyridine-3-Carboxyamide | I-C6H6N2O | 122.13 |
Ukunyibilika: Incibilika ngokukhululekile emanzini nasetshwaleni, inyibilika ku-glycerin
I-Niacinamide noma i-nicotinamide (NAM) iwuhlobo lukavithamini B3 olutholakala ekudleni futhi lusetshenziswa njengesengezo sokudla kanye nemithi. Njengesengezo, isetshenziswa ngomlomo ukuvimbela nokwelapha i-pellagra(ukuntula kwe-niacin). Nakuba i-nicotinic acid (niacin) ingase isetshenziselwe le njongo, i-niacinamide inenzuzo yokungabangeli ukuguquguquka kwesikhumba. Njengokhilimu, isetshenziselwa ukwelapha izinduna. Kuyivithamini encibilika emanzini.
Imiphumela engemihle mincane. Ngemithamo ephezulu, izinkinga zesibindi zingase zenzeke. Amanani avamile aphephile ukusetshenziswa ngesikhathi sokukhulelwa. I-Niacinamide isemndenini kavithamini B wemithi, ikakhulukazi i-vitamin B3 complex. Kuyi-amide ye-nicotinic acid. Ukudla okuqukethe i-niacinamide kuhlanganisa imvubelo, inyama, ubisi, nemifino eluhlaza.
I-Niacinamide yatholwa phakathi kuka-1935 no-1937. Isohlwini Lwemithi Ebalulekile Yenhlangano Yezempilo Yomhlaba. I-Niacinamide itholakala njengomuthi ojwayelekile nangaphandle kwekhawunta. Ngokwezentengiselwano, i-niacinamide yenziwa nge-nicotinic acid (niacin) noma i-nicotinonitrile. Emazweni amaningana okusanhlamvu kunezelwa i-niacinamide kuwo.
I-NicotinamideIsicelo:
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 ingaphumi, ngakho-ke ngeke iqhubeke nokukhiqiza amangqamuzana e-melanin melanin, Okwesibili, i-melanin ngeke ibonwe ngeso lesikhumba ukuze kuzuzwe iso lomuntu.
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 (ukusabela kwe-maillard), izinto ezikhiqizwa yi-saccharification zinsundu, zingavumela isikhumba sibukeke simnyama, ngakho-ke ukumelana ne-mash nakho kusiza ekukhanyeni.ves, izithasiselo zokudla, njll.
Esivivinyweni esilawulwayo sezifundo ezingu-20, amajazi aphindaphindiwe aphindaphindiwe e-nicotinamide ekugxiliseni 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 sebenzisa i-nicotinamide ekhishwe ngaphambi kokufaka i-sunscren.
