- Lub Npe Tag nrho:4- ({2- hydroxyethyl) -1- piperazinehanesulfonic acid
- Molecular hnyav \/ moler loj:238.30 G \/ Mol
- Cov Qauv Txheej Txheem:C₈h₁₈n₂o₄s (muaj piperazine ntiv nplhaib, Sulfonic acid pawg, thiab hydroxyethyl sab saw)
- Phua:6.8-8.2 (Kev muaj txiaj ntsig zoo tshaj plaws ze ntawm lub pheriological ph 7. 0 - 7.6)
Hydroxyethylpiperazine ethane sulfonic acid (hepes), no zwitterionic ntas hmoov zoo yog hloov kho cov tshuaj pleev kom zoo nkauj. Cov Qauv Hepes tshwj xeeb - Featuring ib tug sulfonic acid pawg neeg thiab piperazine nplhaib - ua rau muaj kev tshwj xeeb pH stability), ua rau nws zoo tagnrho rau cov khoom lag luam Skincare cov khoom lag luam.
Daim Ntawv Thov Kom Kos Hniav Kev Siv
- Enzyme stabilization
Saib xyuas cov tshuaj tiv thaiv cov prozymytic hauv exfoliants (piv txwv li, papain cream)
Khaws cov haujlwm ntawm antioxidant enzymes zoo li superoxide dismutase
- Txheeb tshuaj ntxiv
Ntev rau lub rooj sib tiv thaiv lub neej los ntawm kev tiv thaiv ph drift hauv cov dej-ntawm cov quav
Tau tshaj parabens thiab phenoxyethanol (hepes SDS lees paub cov khoom siv tsis zoo)
- Lub luag haujlwm nquag
Boosts nkag mus rau cov vitamin C (l-ascorbic acid) ntawm pH 7. 2-7. 6
Tiv thaiv kev ua kom muaj kev mob siab ntawm peptradation ntawm peptrides hauv kev tiv thaiv kev laus
- Cov lus qhia tsim qauv
Hepes Kev Npaj Txog Kev Npaj Ua: Dissve 2.38% w \/ v in distilled dej, kho rau PH 7.4
Ntau tshaj 0. 5% concentration nyob rau hauv cov khoom lag luam tawm (rau ib lub ntsiab lus uas muaj kev nyab xeeb rau kev nyab xeeb)
Nco ntsoov ua ke nrog chelating cov neeg sawv cev (EDTA) los tiv thaiv cov tshuaj khib nyiab-olidation
Vim li cas thiaj xaiv cov kws kho mobHepes
- Superior rau citrates \/ phosphates nyob rau hauv high-ethanol toners
- Tsis-cuam tshuam nrog tus qauv viscifiers (tsis zoo li tris buffers)
- Thermally ruaj khov txog 50 degree (hepes molarrant tseem tas mus li)
