Cov txiaj ntsig ntawm undecylenoyl phenylalanine
Undecylenoyl phooylalanine kev ua ntawm biochemical cov kev tawm tsam ntawm ntau theem ntawm kev ua txhaum melanin, ua rau muaj kev sib cuam tshuam Melanin, ua rau muaj kev sib cuam tshuam Melanin, thiab yog li ua rau muaj melanin tsim. Mas siv raws li cov neeg ntxuav hniav dawb hauv cov tshuaj pleev ib ce.
Nws tuaj yeem khi nrog nicotinamide, uas tuaj yeem tiv thaiv melanin synthesis los ntawm cov duab me me (piv txwv li inhibit melanin kev thauj khoom melanin ntau lawm) , Ua haujlwm ua ke kom ua tiav whitening thiab tej teeb meem teeb meem cuam tshuam. Nws tuaj yeem siv los npaj cov tshuaj pleev xim ruaj khov, qab zib, pob tshab dej lossis gel, thiab lwm yam.
Nws muaj cov tawv nqaij tseem ceeb biocompatibility, yog kev nyab xeeb nyob rau hauv cov tshuaj pom zoo ntau ntawm 2%, yooj yim los tsim, muaj kev sib raug zoo, thiab kev ruaj khov zoo, thiab kev ruaj khov zoo, thiab kev ruaj khov zoo. Piv nrog whitiling cov neeg sawv cev xws li arbutin, cov vitamins, thiab vitamin C Magnivium Phosphate, cov nyhuv yog qhov tseem ceeb tshaj plaws.
Undecylenoyl phenylalanine kev nyab xeeb
CTFA tau lees paub Unitecylenoyl phenylalanine ua cov khoom siv raw rau cov tshuaj pleev ib ce;
Cov phau ntawv qhia thoob ntiaj teb ntawm Suav Cov Khoom Siv Cov Khoom Siv Cov Khoom Siv Raw rau xyoo 2010 thiab tshaj tawm cov npe ntawm CFDA hauv 2014 ob qho tib si suav nrog Uncecylenoyl phenylalanine. Tsis muaj kev ceeb toom qhia tias undecylenoyl phenylalanine tsis muaj kev nyab xeeb rau kev siv sab nraud.
Cov Khoom Siv Kom Zoo
Txais tos tiv tauj peb
Rau kaum peb xyoos, zhenyibio tau tsom rau ntxuav hniav dawb. Raws li cov kws tshaj lij kev tsim khoom ntawm United Unitedlessl Phenyylalaninen, peb txuas ntxiv txhim kho cov txheej txheem ntau lawm thiab ntxiv dag zog cooperative cov kev pabcuam.
