Dab tsi yog cov khoom tseem ceeb ntawm cov roj luam yeeb hluav taws xob?

Cov roj luam yeeb hluav taws xob feem ntau yog tsim los ntawm plaub yam: glycerol (VG), propylene glycol (PG), spices, thiab nicotine. Hauv qab no, peb yuav muab koj cov ncauj lus kom ntxaws txog cov haujlwm ntawm plaub yam no:
Glycerol (VG)
Abbreviated li VG, nws yog ib hom tshuaj thiab khoom noj khoom haus additives (feem ntau siv los ua cov khoom qab zib xws li ncuav qab zib thiab chocolates) uas tsis muaj kev phiv rau tib neeg lub cev. Nws yog xim tsis muaj xim thiab tsis muaj ntxhiab, hygroscopic heev, tab sis viscous, uas me ntsis nce qhov nyuaj ntawm kev ntxuav lub atomizer thiab txo qhov ceev ntawm cov roj hloov pauv (kuj yooj yim kom qhuav hlawv / muab tshuaj txhuam). VG tuaj yeem raug rho tawm ncaj qha los ntawm cov roj zaub, txiv maj phaub roj, thiab cov roj xibtes, rhuab mus rau qhov kub thiab txias, thiab tom qab ntawd distilled rau purification. Yog li USP zaub mov qib zaub glycerin siv hauv cov kua siv hluav taws xob tsis tu ncua muaj purity ntawm 99.7% +0.3% dej.
Propylene glycol (PG)
Kuj hu ua PG, nws yog siv los dilute lub viscosity ntawm VG. Moisture absorbing, me ntsis qab zib, tsis muaj xim thiab tasteless, nrog fluidity zoo li dej. US Food and Drug Administration (FDA) piav qhia txog PG li "feem ntau muaj kev nyab xeeb rau tib neeg lub cev" (xws li tsuas yog noj) thiab yog ib qho tshuaj thiab zaub mov ntxiv. PG muaj cov roj conductivity zoo thiab ua rau "cov pa luam yeeb me me" thiab "caj pas" zoo ib yam li kev haus luam yeeb.
PG tau raug lees paub los ntawm FDA cov kev tshawb fawb kom raug cais raws li kev nyab xeeb ntxiv (xa mus rau kev noj tshuaj xwb), txawm hais tias nws kuj yog ib qho ntawm cov khoom siv rau kev tiv thaiv kab mob, feem ntau siv hauv kev ua kom tsis muaj zog thiab khoom noj khoom haus thiab dej haus nrog cov kev cai tshwj xeeb. Txawm hais tias PG feem ntau muaj kev nyab xeeb, tseem muaj cov neeg tsawg tsawg uas yuav muaj cov tsos mob tsis haum me me, xws li caj pas tsis xis nyob, phlegm, kiv taub hau, thiab lwm yam. Cov kev mob tshwm sim no luv luv thiab me me.
FDA cov lus tshaj tawm yog qhov tseeb "Feem ntau lees paub tias muaj kev nyab xeeb (GRAS)", uas yog hais txog "kev noj mov". Lwm txoj hauv kev xws li nqus pa, txhaj tshuaj, lossis siv hauv zos tsis nyob hauv thaj tsam ntawm GRAS! Yog li ntawd, kev nyab xeeb ntawm aerosols uas ua los ntawm atomizing e-luam yeeb nrog e-kua tsis nyob rau hauv lub Scope ntawm FDA lav.
Artificial los yog natural essence
Ntxiv nrog rau kev haus luam yeeb tsw, ntau yam txuj lom uas tuaj yeem siv tau los tsim cov khoom sib txawv thiab ntau yam, xws li txiv hmab txiv ntoo, khoom qab zib, dej haus, thiab lwm yam khoom qab zib.
nicotine
Nicotine yog ib qho tshuaj tiv thaiv. Piv nrog rau kev haus luam yeeb, cov ntsiab lus nicotine hauv cov roj luam yeeb tau raug pov thawj tias muaj kev nyab xeeb rau tib neeg noj. Tau kawg, kuj tseem muaj cov roj nicotine tsis pub haus luam yeeb muaj muag hauv khw.
