Nitrous oxide, feem ntau hu ua luag nyav, tau siv rau ntau lub hom phiaj nrog rau kev kho mob thiab kev ua noj ua haus. Txawm li cas los xij, muaj qhov sib txawv tseem ceeb ntawm qib kho mob nitrous oxide thiab qib zaub mov nitrous oxide uas tseem ceeb kom nkag siab.
Nitrous oxide (N2O) yog cov tsis muaj xim, tsis muaj nplaim taws nrog cov ntxhiab tsw qab thiab saj. Nws tau siv ntau tshaj ib puas xyoo hauv kev kho mob thiab kho hniav raws li tshuaj loog thiab tshuaj loog. Tsis tas li ntawd, nws yog siv nyob rau hauv kev lag luam khoom noj khoom haus raws li ib tug propellant nyob rau hauv whipped cream dispensers thiab nyob rau hauv tsim ntawm tej yam khoom noj khoom haus.
Kev kho mob qib nitrous oxide yog tsim thiab ua kom huv si kom tau raws li cov qauv nruj raws li cov chaw tswj xyuas xws li Tebchaws Meskas Pharmacopeia (USP) lossis European Pharmacopoeia (Ph. Eur.). Nws dhau los ua kev sim nruj kom paub meej tias nws tsis muaj impurities thiab cov kab mob sib kis, ua rau nws muaj kev nyab xeeb rau kev siv hauv cov txheej txheem kho mob. Kev kho mob qib nitrous oxide feem ntau yog siv rau kev tswj qhov mob thaum cov txheej txheem kho mob me thiab kho hniav.
Ntawm qhov tod tes,zaub mov qib nitrous oxideyog tsim tshwj xeeb rau kev siv hauv kev ua noj ua haus. Nws feem ntau yog siv los ua ib qho kev tawm tsam hauv cov kaus poom aerosol los tsim cov nplaum nplaum thiab lwm yam foams. Khoom noj khoom haus qib nitrous oxide yog tswj hwm los ntawm cov neeg saib xyuas kev nyab xeeb khoom noj kom ntseeg tau tias nws ua tau raws li cov qauv tsim nyog purity rau kev noj. Thaum nws muaj kev nyab xeeb rau kev siv hauv kev npaj zaub mov, nws tsis haum rau kev kho mob lossis kev siv kho hniav vim tias muaj peev xwm muaj impurities.
Thawj qhov sib txawv ntawm qib kho mob nitrous oxide thiab zaub mov qib nitrous oxide nyob rau hauv lawv purity thiab npaj siv. Kev kho mob qib nitrous oxide tau dhau los ua cov txheej txheem ua kom huv huv ntau dua thiab kuaj xyuas kom ntseeg tau tias nws ua tau raws li cov qauv siab tshaj plaws rau kev siv kho mob. Nws yog ib qho tseem ceeb rau cov neeg mob kev nyab xeeb uas tsuas yog qib kho mob nitrous oxide yog siv nyob rau hauv cov chaw kho mob kom tsis txhob muaj feem cuam tshuam txog kev noj qab haus huv cuam tshuam nrog impurities.
Hauv qhov sib piv, cov zaub mov qib nitrous oxide yog tsim tshwj xeeb rau kev ua noj ua haus thiab ua raws li cov cai uas tau teev tseg los ntawm cov tub ceev xwm kev nyab xeeb khoom noj. Txawm hais tias nws yuav muaj kev nyab xeeb rau kev noj thaum siv hauv kev npaj zaub mov, nws tsis haum rau kev kho mob vim tias muaj cov kab mob sib kis uas tuaj yeem ua rau muaj kev phom sij rau cov neeg mob.
Kev siv qib tsim nyog ntawm nitrous oxide yog qhov tseem ceeb rau kev ua kom muaj kev nyab xeeb hauv kev kho mob thiab ua noj ua haus. Cov kws kho mob yuav tsum ua raws li cov lus qhia nruj thiab cov cai thaum siv nitrous oxide rau tshuaj loog lossis kev tswj qhov mob kom txo tau qhov kev pheej hmoo ntawm kev tsis zoo rau cov neeg mob. Ib yam li ntawd, cov kws tshaj lij kev lag luam khoom noj yuav tsum xyuas kom meej tias cov zaub mov qib nitrous oxide siv lub luag haujlwm raws li cov qauv kev nyab xeeb khoom noj kom tsis txhob muaj kev phom sij cuam tshuam nrog kev sib kis.
Nws tseem yog ib qho tseem ceeb rau cov neeg siv khoom kom paub txog qhov sib txawv ntawm qib kev kho mob thiab qib zaub mov nitrous oxide thaum siv cov khoom uas muaj cov roj no. Txawm hais tias siv whipped cream dispensers hauv tsev los yog ua raws li cov txheej txheem kho mob, kev nkag siab qhov tseem ceeb ntawm kev siv cov qib zoo ntawm nitrous oxide tuaj yeem pab tiv thaiv kom tsis txhob muaj kev phom sij rau kev noj qab haus huv.
Cov koom haum tswj hwm xws li US Food and Drug Administration (FDA) thiab European Medicines Agency (EMA) ua lub luag haujlwm tseem ceeb hauv kev saib xyuas kev tsim khoom, kev faib tawm, thiab kev siv tshuaj qib nitrous oxide. Cov koom haum no tau teeb tsa cov qauv nruj rau kev coj dawb huv, kev sau npe, thiab cov ntaub ntawv los xyuas kom meej tias tsuas yog cov khoom muaj txiaj ntsig zoo nitrous oxide yog siv hauv kev kho mob.
Ib yam li ntawd, cov neeg saib xyuas kev nyab xeeb khoom noj xws li US Food and Drug Administration (FDA) thiab European Food Safety Authority (EFSA) tswj kev tsim khoom thiab siv cov zaub mov qib nitrous oxide los tiv thaiv cov neeg siv khoom noj qab haus huv. Cov koom haum no tsim cov txheej txheem rau purity, labeling, thiab tso cai siv cov zaub mov qib nitrous oxide nyob rau hauv daim ntawv thov ua noj.
Hauv kev xaus, qhov sib txawv ntawm qib kho mob nitrous oxide thiab zaub mov qib nitrous oxide yog qhov tseem ceeb rau kev nkag siab txog lawv cov kev siv thiab kev saib xyuas kev nyab xeeb. Kev kho mob qib nitrous oxide yog nruj me ntsis ua kom huv thiab sim ua kom tau raws li cov qauv siab tshaj plaws rau kev siv tshuaj kho mob, thaum zaub mov qib nitrous oxide yog npaj rau kev siv ua noj thiab ua raws li cov cai tswj kev nyab xeeb ntawm zaub mov. Los ntawm kev paub txog qhov sib txawv no thiab ua raws li cov qauv kev cai, cov kws kho mob, cov kws tshaj lij kev lag luam, thiab cov neeg siv khoom tuaj yeem ua kom muaj kev nyab xeeb thiab tsim nyog siv nitrous oxide hauv lawv qhov chaw.
