1. Dab tsi yog gluconolactone?
Glucoolactoneyog cov hmoov dawb dawb crystalline muab los ntawmgluconic acid, cov khoom tsim khoom los ntawm cov tsiaj txhu thaum lub sij hawm carbohydrate metabolism[1]Cov. Kev Lag Luam, feem ntau yog feem ntau tsim los ntawm fermentation ntawm pob kws - derived qab zib[2]Cov. Raws li polyhydroxy acid (pha), nws maj mam hloov siab hloov rau cov kua qaub hauv cov kev daws teeb meem aqueous.
2. Cov txiaj ntsig kev noj qab haus huv ntawmGlucoolactoneHmoov
Kev tshawb fawb qhia tau gluconolactone yuav muab:
- Kev tshem tawm maj mam: hydrolyzes rau hauv cov kua qaub zoo siab rau ntawm daim tawv nqaij lub v (4.5-5.5), pab hauv lub xov tooj ntawm tes tuag tsis muaj voos[3].
- Antioxidant kev ua: chelates hlau ions uas ua rau oxidative kev ntxhov siab hauv cov tshuaj pleev ib ce[4].
- Kev cai ya raws: Cov ntawv nyiam nyiam zaj yeeb yaj kiab hauv cov khoom tu tus kheej ntawm 4-12% ntau[5].
- Kev Tswj Khoom Noj: Ua haujlwm ua ib qho me me acidulant thiab ua ntu zus nyob rau hauv cov mis nyuj / nqaij ntawm 0.1-0.5%[6].
Nco tseg: Cov teebmeem: raws li cov khoom siv dag zog thiab hauv cov kev tshawb fawb vters.
3. Muaj cov ntawv thov
Kev Lag Luam Khoom Noj
- Aub qhuav: Kho cov khoom lag luam mis nyuj (yogurt, cheese) nrog qeeb acid tso tawm[7]
- Cov Ntaub Ntawv Pab Tiv Thaiv: Txhim kho kev ua tau zoo ntawm cov tshuaj tiv thaiv nqaij hauv nqaij ua noj
- Cov tshuaj uas muaj poov xab: Cheebtsam ntawm qeeb - Tshaj tawm cov hmoov nplej
Kev Lag Luam Kev Lag Luam
- Txog Phha Exfoliants: Siv rau hauv cov huv (3-8%) thiab toners (2-5%) rau cov tawv rhiab[8]
- Lub stababilizer: Saib xyuas cov tshuaj muaj cov khoom xyaw pal - rawv cov qauv
- Anti - oxidant tshuaj: Syneroes nrog cov vitamin C derivatives ntawm 0.5-2%
Kev Siv Khoom Siv
- Hlau ntxuav: Tshem tawm cov ntxhia tso nyiaj hauv kev lag luam descaling daws
- Kws khaws cia: Ntsiav tshuaj cuam tshuam nrog kev txhim kho cov lus qhia
4. Cov Lus Nug
Q: Puas yog gluconolactone muaj kev nyab xeeb noj?
A: Nws tuav tau GRAS (feem ntau lees paub tias muaj kev nyab xeeb) xwm txheej los ntawm FDA (21cfr184.1318) thiab tau pom zoo ua zaub mov ntxiv E575 hauv EU[9].
Q: Nws puas yog ntuj?
A: Thaum ib txwm muaj tshwm sim, cov khoom lag luam yog feem ntau fermented los ntawm cov nroj tsuag - dered qab glucose. Cov ntawv pov thawj (piv txwv li, Cosmos) txhais tau cov txheej txheem ntau lawm.
Q: Nws txawv li cas ntawm glucuronolactone?
A: Txawm tias muaj cov npe zoo sib xws, lawv muaj cov sib txuas sib txawv. Glucuronolactone yog lub siab metabolite siv nyob rau hauv lub zog haus, thaum gluconolactone yog feem ntau yog acidulant / phas.
Q: Dab tsi yog nws cov p p hauv cov qauv?
A: Hauv 1% kev daws teeb meem, phua li ntawm 3.0-3.5. Cov ntawv sau hloov kho rau hom phiaj pH uas siv cov tshuab tsis sib haum.
Q: Puas tsim nyog nws hloov aha exfoliants?
A: Raws li molecular loj pha, nws nkag mus qeeb dua glycolic acid, ua rau muaj peev xwm txo qhov muaj peev xwm[10].
