Raws li ib feem ntawm cov teeb meem ua los tiv thaiv kev sib kis ntawm Covid-19, kev siv cov kua dej cawv muaj cawv yog ib feem ntawm cov kev daws teeb meem kom sai thiab muaj txiaj ntsig tsis ua haujlwm ntawm ntau cov kab mob me me uas tuaj yeem pom ntawm tes. Dhau li ntawm WHO tus qauv, muaj cov zaub mov hauv tsev.

Thaum ntxuav tes nrog xab npum thiab dej tsis tau, WHO pom zoo kom siv cov tshuaj sai sai kom qhuav hydroalcoholic (SHA) tov (lossis gel) tsim tshwj xeeb rau kev siv tshuaj tua kab mob.

Cov khoom no muaj cawv (tsawg kawg yog 60%) lossis ethanol, ib qho emollient, thiab qee zaum muaj tshuaj tua kab mob. Lawv tau thov los ntawm kev sib txhuam yam tsis tau yaug ntawm tes qhuav thiab zoo li huv si (uas yog hais tias tsis pom cov av).

Cawv ua rau cov kab mob (suav nrog mycobacteria yog tias muaj kev sib cuag mus ntev) ntawm cov hnab ntim kab mob (SARS CoV 2, kab mob khaub thuas, HIV, kab mob vwm, thiab lwm yam), ntawm cov kab mob. Txawm li cas los xij, ethanol ua rau muaj kab mob ntau dua li povidone, chlorhexidine, lossis xab npum siv los ntxuav tes yooj yim. Kev ua tshuaj tua kab mob ntawm ethanol yog qhov tseem ceeb. Kev ua dej cawv yog nyob ntawm qhov ua kom siab, nws qhov ua tau zoo sai sai ntawm ntub tes.

Nws siv yooj yim ua rau nws yog gel uas tuaj yeem siv tau nyob txhua qhov chaw thiab uas tau coj los nyob hauv tus cwj pwm huv.

Kev npaj thiab kev tsim cov khoom lag luam tam sim no tuaj yeem ua los ntawm cov chaw tsim khoom xws li cov chaw soj ntsuam tshuaj rau cov khoom siv tshuaj rau tib neeg siv lossis cov chaw sim tshuaj pleev ib ce. 

Raws li World Health Organization, hydroalcoholic gel yog tsim los ntawm:

• 96% cawv: tshwj xeeb tshaj yog ethanol uas ua lub luag haujlwm tseem ceeb los tshem tawm cov kab mob.
• 3% hydrogen peroxide los ua tus spore inactivator thiab yog li zam kev tawv nqaij.
• 1% glycerin: glycerol ntau dua uas yuav ua raws li cov tshuaj tsw qab.

Cov mis no tau pom zoo los ntawm WHO rau kev npaj cov tshuaj hydroalcoholic hauv cov chaw muag tshuaj. Tsis yog rau pej xeem sawv daws.

Txoj cai lij choj ntawm Lub Peb Hlis 23, 2020 ntxiv 3 daim ntawv pov thawj pom zoo rau kev tsim khoom ntawm SHA hauv cov chaw muag tshuaj:

• Kev tsim nrog ethanol: 96% V / V ethanol tuaj yeem hloov nrog 95% V / V ethanol (842,1 mL) lossis 90% V / V ethanol (888,8 mL);
• Tsim nrog 99,8% V / V isopropanol (751,5 mL)

Ua ntawv thov cov tshuaj hydroalcoholic gel zoo ib yam li ntxuav tes huv nrog xab npum thiab dej. Nws raug nquahu kom txhuam koj txhais tes kom ntev li 30 vib nas this: xib teg rau xib teg, xib teg rau tom qab, nruab nrab ntawm cov ntiv tes thiab cov rau tes rau ntawm lub dab teg. Peb nres thaum ob txhais tes qhuav dua: qhov no txhais tau hais tias cov tshuaj hydroalcoholic gel tau ua kom tawv nqaij txaus.

Nws tuaj yeem khaws cia rau 1 lub hlis tom qab siv thawj zaug.

Ntsib nrog qhov tsis txaus thiab nce tus nqi ntawm hydroalcoholic daws thaum pib muaj kev kis thoob qhov txhia chaw, Lub Koom Haum Saib Xyuas Kev Noj Qab Haus Huv Ntiaj Teb (WHO) tau tshaj tawm ib daim ntawv qhia rau hydroalcoholic gel hauv nws "phau ntawv qhia rau kev tsim cov tshuaj hydroalcoholic hauv zos".

Rau 1 liter ntawm gel, sib xyaw 833,3 ml ntawm 96% ethanol (hloov tau los ntawm 751,5 ml ntawm 99,8% isopropanol), 41,7 ml ntawm hydrogen peroxide, feem ntau hu ua hydrogen peroxide, muaj nyob hauv cov chaw muag tshuaj, thiab 14,5, 98 ml ntawm 1% glycerol, lossis glycerin, kuj tseem muag ntawm lub tsev muag tshuaj. Thaum kawg, ntxiv cov dej txias txias rau qhov sib xyaw kom txog rau qhov ua tiav qhov cim qhia txog 100 liter. Sib tov txhua yam kom zoo, tom qab ntawd ncuav cov tshuaj daws sai sai, kom tsis txhob muaj dej ntws mus rau hauv lub raj mis (500 ml lossis XNUMX ml).

Nws yog qhov tsim nyog los tso cov vials ntim rau hauv kev cais tawm tsawg kawg 72 teev txhawm rau txhawm rau tshem tawm cov kab mob uas muaj peev xwm muaj nyob hauv cawv los yog hauv lub vials. Kev daws teeb meem tuaj yeem khaws cia rau qhov siab kawg ntawm 3 lub hlis.

Lwm cov zaub mov hauv tsev muaj. Piv txwv li, nws muaj peev xwm ua ke cov dej ntxhia (14 ml), hyaluronic acid (piv txwv li 2 DASH rab diav) uas tso cai rau cov mis rau gel thaum ua kom dej huv ntawm tes, qhov nruab nrab nruab nrab ntawm cov naj hoom organic muaj li ntawm 95% cov organic cawv cawv (43 ml) ) thiab organic tshuaj yej tsob ntoo tseem ceeb roj nrog cov khoom ua kom huv (20 tee).

"Daim ntawv qhia no muaj 60% cawv raws li cov lus pom zoo ntawm ANSES-thiab ANSM (Lub Koom Haum Hauv Tebchaws rau Kev Nyab Xeeb ntawm Tshuaj thiab Khoom Noj Qab Haus Huv), hais qhia Pascale Ruberti, Aroma-Zone R & D tus thawj coj. Txawm li cas los xij, vim qhov no yog daim ntawv qhia ua hauv tsev, nws tsis tau sim ua kom tau raws li Txoj Cai Kev Siv Tshuaj Biocide, tshwj xeeb yog NF 14476 tus qauv ntawm kab mob ".

Txog kev ntxuav tes txhua hnub, tsis muaj dab tsi zoo li xab npum. "Hauv cov khoom ua kua lossis kua, lawv muaj nyob rau hauv qhov nruab nrab lossis ntxhiab tsw, xws li Aleppo xab npum paub txog nws cov khoom ua kom huv ua tsaug rau laurel roj nws muaj, emblematic Marseille xab npum thiab nws 72 % yam tsawg kawg ntawm cov txiv ntseej, thiab raws li xab npum saponified txias, ib txwm muaj cov glycerin thiab cov roj tsis yog saponified zaub (phais) ", piav Pascale Ruberti.

"Tsis tas li ntawd, rau kev xaiv nomadic thiab ua kom yooj yim dua li cov gel, xaiv cov tshuaj pleev hydroalcoholic hauv cov tshuaj tsuag: koj tsuas yog xav tau sib xyaw 90% ethanol ntawm 96 ° nrog 5% dej thiab 5% glycerin. Koj tseem tuaj yeem ntxiv ob peb tee ntawm cov roj ua kom huv xws li tsob ntoo tshuaj yej lossis ravintsara »
