Peb tuaj yeem siv cov tshuaj pleev muaj panthenol los kho tshav kub kub, kub hnyiab, mob me me, thiab mob. Tsis tas li ntawd, nws tuaj yeem txhim kho hydration, txo qhov khaus thiab o ntawm daim tawv nqaij, txhim kho daim tawv nqaij elasticity, thiab ua kom cov kab mob epidermal zoo. Thaum siv panthenol ua ib feem ntawm cov tshuaj zawv plaub hau, nws tuaj yeem khi rau cov plaub hau yooj yim. Nws tuaj yeem pleev xim rau cov plaub hau thiab kaw qhov saum npoo ntawm cov plaub hau kom nws ci ntsa iab.
Feem ntau, panthenol molecules tuaj yeem nkag mus rau hauv daim tawv nqaij thiab cov mucous daim nyias nyias, uas suav nrog cov hnyuv mucosa thiab. Nws sai sai oxidizes rau pantothenic acid. Pantothenic acid yog hygroscopic heev. Nws kuj tseem muaj txiaj ntsig zoo hauv biosynthesis ntawm coenzyme A, uas nyiam ua lub luag haujlwm hauv ntau yam kev cuam tshuam nrog cov enzymes hauv kev loj hlob ntawm tes.
Dexpanthenol yog dab tsi?
Dexpanthenol yog cov organic compound uas muaj cov tshuaj formula C9H19NO4Nws yog ib qho tseem ceeb raws li cov tshuaj, raws li ib tug moisturizer los kho los yog tiv thaiv kom qhuav, ntxhib, scaly, khaus ntawm daim tawv nqaij thiab me me ntawm daim tawv nqaij irritation, thiab lwm yam.. Ntxiv mus, nws yog ib qho tseem ceeb rau kev tiv thaiv tsis muaj vitamin nyob rau hauv cov neeg mob uas tau txais tag nrho cov niam txiv cov khoom noj khoom haus.
Muaj cov npe sib txawv rau dexapanthenol uas suav nrog Fortplex, Infutive, Infutive Pediatric, Mvi pediatric, Neo-bex, thiab lwm yam.
Cov tshuaj no qhia tau hais tias muaj peev xwm nkag mus tau zoo thiab muaj lub zog hauv zos siab, uas ua rau nws muaj txiaj ntsig zoo hauv ntau cov khoom siv tshuaj pleev ib ce, suav nrog tshuaj pleev thiab tshuaj pleev. Cov tshuaj pleev no yog siv los kho cov kab mob dermatological los txo qhov khaus lossis txhawb kev kho mob.
Tsis tas li ntawd, dexpanthenol muaj nyob rau hauv daim ntawv ntawm kev sib xyaw haiv neeg uas muaj ob hom dextrorotatory thiab levorotatory li panthenol. Piv txwv li, pantothenic acid yog optically active, thaum dexpanthenol yog biologically active.
Cov molar loj ntawm cov tshuaj no yog 205.25 g / mol. Lub hydrogen daim ntawv cog lus pub suav ntawm qhov sib xyaw no yog 4, thaum lub hydrogen daim ntawv lees txais suav yog 4 thiab. Tsis tas li ntawd, nws muaj 6 rotatable bonds thiab ib lub stereocenter. Nws muaj nyob rau hauv lub xeev ruaj khov ntawm tus qauv kub thiab siab, uas nws tshwm sim raws li hygroscopic roj los yog raws li ib tug viscous kua nyob rau hauv nws cov kua daim ntawv. Ntxiv mus, nws muaj ib tug me ntsis iab saj.
Thaum qhov kub thiab txias, nws tuaj yeem decompose, tab sis qhov kub kub tuaj yeem muab tau raws li nyob rau hauv thaj tsam ntawm 118-120 degrees Celsius. Lub melting point yog qis dua 25 degrees Celsius. Nws tuaj yeem yaj dawb hauv methanol, dej, thiab cawv, thiab me ntsis soluble hauv ethyl ether. Qhov ceev ntawm dexpanthenol yog 1.2 g / cm3 ntawm 20 ° C. Tsis tas li ntawd, nws yog qhov tsim nyog ruaj khov dua li cov ntsev ntawm pantothenic acid ntawm pH 3-5.
Qhov txawv ntawm Panthenol thiab Dexpanthenol yog dab tsi?
Panthenol tuaj yeem pom hauv ob daim ntawv enantiomeric: L daim ntawv thiab D daim ntawv lossis dexpanthenol. Qhov sib txawv tseem ceeb ntawm panthenol thiab dexpanthenol yog panthenol tsis yog ib txwm ua haujlwm lom neeg, thaum dexpanthenol yog ib daim ntawv lom neeg.
Cov ntawv qhia hauv qab no nthuav tawm qhov sib txawv ntawm panthenol thiab dexpanthenol hauv daim ntawv tabular rau kev sib piv ntawm ib sab.
Summary – Panthenol vs Dexpanthenol
Panthenol yog ib qho organic compound uas muaj cov tshuaj formula C
9H19NO4, Thaum Dexpanthenol yog D enantiomer ntawm panthenol. Qhov sib txawv tseem ceeb ntawm panthenol thiab dexpanthenol yog panthenol tsis yog ib txwm ua haujlwm lom neeg, thaum dexpanthenol yog ib daim ntawv lom neeg.
