Kev ruaj ntseg & Cov ntaub ntawv ua haujlwm

A. Thermal & Discoloration Stability Test (90-Hnub Real-Time Stress Test)

product-625-265

B. pH-Nyob rau ntawm Degradation Curve Data
Formulators feem ntau tawm tsam nrog qhov nqaim pH qhov xav tau rau cov tshuaj vitamin C. Peb cov qauv lipophilic thiab hydrophilic amphiphilic ua kom tsis muaj kev sib haum xeeb thoob plaws pH spectrum.
Qhov zoo tshaj pH ntau yam:4.0 – 6.0 (Zoo rau daim tawv nqaij-barrier- tus phooj ywg formulations).
Degradation tus nqi:Tsawg dua 1.5% active ingredient degradation pom nyob rau hauv 12 lub hlis nyob rau hauv lub optimum pH Scope.
Formulation Benefit:Tshem tawm qhov kev xav tau rau cov neeg kho pH hnyav lossis siab -nqi airless ntim.

C. Transdermal Penetration: Pure Vitamin C vs. 3-O-Ethyl-L-Ascorbic Acid
Kev ruaj ntseg txhais tau tias tsis muaj dab tsi yog tias tus nquag tsis tuaj yeem nkag mus rau stratum corneum. Ua tsaug rau qhov tseeb ethyl hloov kho ntawm 3rd carbon txoj hauj lwm, peb cov molecule hla seamlessly los ntawm lipid bilayers.
Daim tawv nqaij Absorption Rate:4.3x siab dua ntawm daim tawv nqaij nqus thiab tuav tus nqi ntau dua li tus qauv L-Ascorbic Acid.
Hauv -Vivo Conversion:Thaum nqus tau rau hauv daim tawv nqaij, nws tau zoo metabolized rau hauv dawb L-ascorbic acid los ntawm cov enzymes ib txwm muaj, muab 80% + kev hloov pauv tam sim ntawd los ua rau cellular collagen synthesis thiab tyrosinase inhibition.

Daim ntawv thov

3-O-Ethyl-L-ascorbic acid, kuj paub los ntawm nws lwm lub npe ethyl ascorbic acid, yog ib tug derivative ntawm vitamin C (ascorbic acid).
Nws yog dej-soluble tab sis nthuav tawm ib feem ntawm cov roj solubility, txhim kho nws cov tawv nqaij nqus efficiency.
Brightening ntawm daim tawv nqaij / Txo hyperpigmentation / yav tsaus ntuj tawm ntawm daim tawv nqaij
