Taw Qhia: Ib Cov Lus Nug Cov Neeg Yuav Tsis Nco Nug
Provitamin B5 hmoovyog ib qho ntawm cov khoom siv tshuaj pleev ib ce ntau tshaj plaws hauv kev lag luam. Nws tshwm sim nyob rau hauv cream, tshuaj pleev ib ce, serums, tshuaj zawv plaub hau, thiab conditioners. Kev thov tau nce ntxiv - panthenol cream tshawb nrhiav tau nce ntau dua 1,000% ntawm TikTok, nrog rau tag nrho cov kev tshawb nrhiav tau nce 86.4% xyoo-rau- xyoo.
Tab sis ntawm no yog qhov kev yuav khoom tiag tiag uas ntes tau ntau tus qauv tsim tawm ntawm tus neeg saib xyuas:"Provitamin B5" yog lub npe qeb, tsis yog qhov tshwj xeeb.
Raws li lub npe ntawd, lub khw muag khoomob qib chemically txawv- D-Panthenol thiab DL-Panthenol - thiab ob leeg nqa tib lub npe INCI: Panthenol. Lub npe lag luam ib leeg tsis qhia koj tias koj yuav khoom dab tsi. Qhov blog no rhuav tshem qhov sib txawv, qhov cuam tshuam ntawm kev noj tshuaj, thiab kev txiav txim siab tsim ua raws li.
1. D-Panthenol vs DL-Panthenol: Qhov txawv ntawm qhov tseem ceeb
Qhov txawv yogstereochemistry.
| Parameter | D-Panthenol | DL -Panthenol |
|---|---|---|
| Stereochemistry | Ib leeg enantiomer (D-form) | Racemic sib tov, D:L ≈ 50:50 |
| CAS Nr. | 81-13-0 | 16485-10-2 |
| INCI npe | Panthenol | Panthenol |
| Active isomer cov ntsiab lus | Ua tau zoo qhov kev ntsuam xyuas tag nrho | Kwv yees li ib nrab ntawm qhov kev xeem |
| Cov ntawv zoo sib xws | Hmoov; 75% daws | Hmoov; 50% thiab 75% kev daws teeb meem |
D-Panthenolyog D-enantiomer - ib leegbiologically nquag configuration. Cov tshuaj vitamin yog txwv rau D- daim ntawv. Thaum siv rau ntawm daim tawv nqaij, D-Panthenol hloov mus rau pantothenic acid (vitamin B5), ib feem ntawm coenzyme A, uas ua lub luag haujlwm tseem ceeb hauv fatty acid thiab sphingolipid synthesis rau stratum corneum lipid bilayers.
DL -Panthenolyog ib haiv neeg sib xyaw ntawm D- thiab L- cov ntawv. L- feem yog nqatsis muaj vitamin ua haujlwm. A DL qib yog li khoom siv kwv yeesib nrab ntawm nws pawg raws li active D-isomer.
Qhov no txhais li cas rau koj tus qauv:Ntawm qhov sib npaug tshaj tawm qhov concentration, DL-Panthenol muab kwv yees li ib nrab ntawm cov vitamin B5 txoj hauv kev ntawm D-Panthenol. Ob tug yogtsis interchangeablenyob rau tib lub tswv yim feem pua.
2. Vim li cas qhov no tseem ceeb rau kev tsim
-
Kev suav tshuaj
Cov ntaub ntawv nyoos - feem pua koj xav tau yoglub hom phiaj active theem muab faib los ntawm cov active feem ntawm qib muab.
Rau 1.0% lub hom phiaj active theem:
A 98% D-Panthenol hmoovxav tau kwv yees li1.02%nkag
A 50% DL-Panthenol tovxav tau kwv yees li2.00%nkag
Yog tias tus qauv qhia tau hais tias "1% Provitamin B5" yam tsis tau sau cov qib, cov khoom tiav tuaj yeem muaj nyob qhov twg los ntawm 0.5% mus rau 1.0% nquag D-isomer - 2 × variation hauv kev xa tawm.

Nqe Lus Nug
DL-Panthenol feem ntau yog tus nqi ntau dua- siv tau rau ib kilogram ntawm cov khoom siv. Rau formulations qhov specification yog sau rautag nrho cov ntsiab lus panthenolthiab daim ntawv thov moisturizing yog txaus, DL-Panthenol muab qhov sib npaug humectant kev ua haujlwm ntawm tus nqi qis.
For formulations qhov twg specification fix aD-isomer xav tau- los yog qhov twg lub hom phiaj kev lag luam xav tau pharma- cov ntaub ntawv qib - D-Panthenol yog qhov kev xaiv raug.
3. Qhov Science Hais
D-Panthenol muaj qhov zoo- tsim kho lub hauv paus:
- Kev kho Barrier:Xya hnub ntawm kev kho tshuaj pleev dexpanthenol txhim kho stratum corneum hydration thiab txo cov dej transepidermal.
- Kev tiv thaiv kab mob:Dexpanthenol nthuav tawm cov teebmeem tiv thaiv kev ua xua ntawm daim tawv nqaij hauv ob - dig muag, placebo- tswj kev sim.
- Kev kho mob:Dexpanthenol hloov mus rau pantothenic acid nyob rau hauv cov ntaub so ntswg, txhawb coenzyme A synthesis tseem ceeb rau stratum corneum lipid bilayers thiab cell membrane kev ntseeg.
- Tshaj tawm - txheej txheem rov qab:Dexpanthenol- muaj cov tshuaj pleev kom ceev cov kab mob epidermal kho nyob rau hauv tib neeg 3D daim tawv nqaij qauv tom qab micro- needling.
Cov txiaj ntsig no raug ntaus nqi tshwj xeeb rau covD- daim ntawv- daim ntawv uas hloov mus rau vitamin B5 hauv daim tawv nqaij. Daim ntawv L- hauv qib DL tsis ua rau cov vitamin ua haujlwm.
