Cov yam ntxwv ntawm cov khoom:
1 Clearing dawb radicals
Ferulic acid muaj cov nyhuv antioxidant muaj zog, uas tuaj yeem tshem tawm cov pa dawb radicals, inhibit enzymes uas tsim cov dawb radicals, txhawb kev tsim cov enzymes uas tshem tawm cov dawb radicals, tshem tawm oxidative kev puas tsuaj rau cell membranes thiab DNA tshwm sim los ntawm dawb radicals, thiab tiv thaiv lub cev los ntawm dawb radical puas.
2 Kev ntxuav hniav dawb
Ferulic acid tuaj yeem tiv thaiv kev ua haujlwm ntawm B16V hauv melanocytes, thiab siv 0.1-0.5% ferulic acid tov tuaj yeem txo cov melanocytes ntawm 117 ± 23 / mm2 rau 39 ± 7 / mm2; Tib lub sijhawm, ferulic acid tuaj yeem cuam tshuam cov Kev ua haujlwm ntawm tyrosinase.A cov tshuaj ferulic acid nrog qhov siab ntawm 5mmol / L tuaj yeem cuam tshuam tyrosinase kev ua haujlwm txog li 86%. 35%.
3 Resistance rau UV puas
Ferulic acid muaj ib tug khub ntawm conjugated ob daim ntawv cog lus, uas muaj zog nqus ntawm UV rays xws li los ntawm 290 mus rau 350nm.Thaum ib tug concentration ntawm 0.7%, nws muaj peev xwm tiv thaiv tau cov tawv nqaij liab los ntawm UVB, tiv thaiv thiab txo UV puas rau ntawm daim tawv nqaij; Ferulic acid pab tiv thaiv cell puas los ntawm ultraviolet hluav taws xob, txhim kho daim tawv nqaij muaj peev xwm tiv thaiv photoaging thiab tiv thaiv kab mob ntawm daim tawv nqaij.
4 Anti-inflammatory
Ferulic acid muaj cov tshuaj tiv thaiv kab mob thiab dav-spectrum los tiv thaiv kev ua xua, thiab inhibitory tus nqi ntawm IL-4 ntawm ib qho concentration ntawm 4umol / L yog 18.2%.
5 Bioavailability
Ferulic acid muaj ib qho tseem ceeb transdermal absorption txhawb cov nyhuv, nrog cov tawv nqaij zoo permeability thiab siab bioavailability.
Cov khoom ntsuas
Daim ntawv thov khoom
Cov lus pom zoo: 0.1% ~ 0.5%
★ Anti aging thiab anti wrinkle khoom
★ Cov khoom siv tshuaj pleev thaiv hnub
★ Whitening thiab freckle tshem tawm cov khoom
★ rhiab rau cov nqaij ntshiv thiab cov khoom kho mob
★ Cov khoom muag muag
Daim ntawv qhia tswv yim
Muaj peev xwm pH: 3.0-6.0.
Ferulic acid yog soluble hauv dej kub, tab sis tuaj yeem yooj yim precipitate tom qab txias; Nws raug nquahu kom siv cov polyols nyob rau hauv lub cev thiab ntxiv cov cosolvent ethoxydiethylene glycol.Thiab kho cov pH rau ib ncig ntawm 5.0 yog qhov zoo rau qhov kub thiab txias, thiab ib qho chaw pH siab heev tuaj yeem yooj yim nrawm rau oxidation thiab discoloration ntawm ferulic acid.
Ntim specifications
1kg / hnab, 25kg / chim
Cia
Khaws rau hauv qhov chaw txias (<25 ℃), qhuav, thiab qhov chaw tsaus, kaw thiab khaws cia.Nws yuav tsum tau siv sai li sai tau tom qab qhib lub foob; Raws li kev pom zoo cia, cov khoom tsis tau qhib muaj lub txee lub neej ntawm 24 lub hlis.
