PGA & HA: Synergistic Enhancement, Hais Goodbye rau Stickiness, Moisturizing thiab Antioxidant Duet

# Taw qhia

Sodium polyglutamate (PGA)yog ib qho dej-soluble polymer tsim los ntawmmicrobial fermentation.Nws yog dav siv nyob rau hauvtu tawv nqaijcov khoom thiabtshuaj pleev ib cevim nws zoo heev moisturizing zog thiab multifunctional zog.Kab lus no yuav qhia txog qhov chaw, tshuaj qauv, yam ntxwv thiab kev siv ntawmsodium polyglutamatehauv cov khoom tu tawv nqaij kom ntxaws.

#Qhov chaw thiab cov qauv tshuaj

Sodium polyglutamatethawj zaug pom nyob rau hauv natto, ib txwm Japanese zaub mov.Cov viscous heev hauv natto yogPGA.Cov khoom no yog polymerized los ntawm ntuj thiab degradable glutamic acid thiab tsim los ntawm fermentation ntawm Bacillus subtilis.Bacillus subtilis yog ib qho kev lees paub thoob ntiaj teb kev nyab xeeb microbial additive (GRAS) hom, ib txwm muab los thiab nyab xeeb rau tib neeg lub cev.

Lub hauv paus qauv ntawmPGAyog tsim los ntawm 5000-10000 glutamic acid molecules polymerized los ntawmγ-amide daim ntawv cog lus.Cov molecule muaj ntau pawg polar pawg xws li hydroxyl thiab carboxyl pawg, uas tuaj yeem tsim cov hydrogen bonds hauv thiab nruab nrab ntawm cov molecules, yog li khi cov dej ntau thiab txhim kho nws cov moisturizing nyhuv.

# Nta thiab cov nyhuv

1.**Kev ua haujlwm zoo moisturizing**: PGA tuaj yeem nqus tau thiab kaw cov dej ntau, txhim kho cov dej ntawm daim tawv nqaij.Thaum siv nrogsodium hyaluronate (HA) hmoov, nws tuaj yeem ua kom lub sijhawm moisturizing ntawm HA, txo nws cov nplaum, thiab ua rau daim tawv nqaij zoo dua qub thiab du.

2.**Antioxidant kev ua haujlwm**: PGA muaj cov haujlwm antioxidant, tuaj yeem tshem tawm cov dawb radicals, thiab tiv thaiv daim tawv nqaij los ntawm kev puas tsuaj oxidative.Cov kev tshawb fawb tau pom tias PGA nrog qhov hnyav molecular ntawm 1.4 lab Da ua tau zoo me ntsis zoo dua PGA nrog qhov hnyav molecular ntawm 1 lab Da hauv kev tshem tawm DPPH dawb radicals.

3. **Ua kom cov ntsiab lus ntawm natural moisturizing factor (NMF) hauv daim tawv nqaij**: PGA tuaj yeem txhawb kev tsim NMF hauv daim tawv nqaij, txhim kho qhov muaj peev xwm moisturizing ntawm daim tawv nqaij, thiab ua tiav cov txiaj ntsig ntawm kev noj qab haus huv sib sib zog nqus.

4. **Whitening thiab anti-aging**: PGA tuaj yeem maj mam tswj cov haujlwm ntawm tyrosinase, ncua kev tsim cov pob, thiab tib lub sijhawm txhim kho kev ruaj ntseg ntawm HA hauv daim tawv nqaij, nce HA cov ntsiab lus, thiab ua tiav cov txiaj ntsig ntawm kev ntxuav hniav dawb thiab tiv thaiv kev laus.

# Molecular Nyhav thiab Daim Ntawv Thov

Raws li qhov hnyav molecular, PGA tuaj yeem muab faib ua peb hom: siab molecular hnyav, nruab nrab molecular hnyav thiab qis molecular hnyav, txhua tus muaj cov yam ntxwv sib txawv thiab kev siv:

-**PGA-HMW (siab molecular hnyav,> 700kDa)**: ntev-ntev moisturizing, tsim ib tug moisturizing zaj duab xis ntawm daim tawv nqaij nto, ho txhim kho cov nyhuv moisturizing.

-**PGA-LMW (qhov nruab nrab molecular hnyav, 70-150kDa)**: moisturizing thiab whitening, txhim kho daim tawv nqaij radiance thiab elasticity.

-**PGA-Oligo (tsis tshua muaj molecular hnyav, <10kDa)**: kev noj qab haus huv sib sib zog nqus, ncaj qha mus txog txheej basal, txhawb NMF tiam thiab nqus cov as-ham.

# Daim ntawv thov thiab siv cov lus qhia

PGA yog tsim rau moisturizing, anti-aging thiab whitening khoom, nrog ib tug pom zoo concentration ntawm0.1% mus rau 1%.Anti-ionic emulsifiers yuav tsum tau siv ntau li ntau tau hauv cov mis los ua kom zoo dua cov nyhuv ntawm PGA.

#Xov xwm

Raws li lub ntuj tsim, nyab xeeb thiab siv tau biopolymer,sodium polyglutamate (PGA)qhia tau hais tias muaj peev xwm siv tau zoo hauv cov khoom tu tawv nqaij thiab tshuaj pleev ib ce.Nws cov khoom zoo moisturizing, kev ua haujlwm antioxidant thiab ntau yam txiaj ntsig rau kev noj qab haus huv ntawm daim tawv nqaij ua rau nws yog ib qho tseem ceeb hauv cov khoom siv tu tawv nqaij niaj hnub.Nrog rau kev sib sib zog nqus ntawm kev tshawb fawb thiab kev nce qib ntawm kev siv technology,PGAyuav tsum tau ua lub luag haujlwm tseem ceeb hauv ntau qhov chaw thiab coj ntau qhov kev tsim kho tshiab thiab kev loj hlob rau kev siv thev naus laus zis.
