HPMC rau Hand Sanitizer

Cov tshuaj ntxuav tes yog cov khoom siv tshuaj txhua hnub uas nquag siv hauv lub neej txhua hnub. Vim yog tus kab mob COVID-19, nws tau dhau los ua neeg nyiam. Hydroxypropyl methylcellulose HPMC, uas yog ib qho tseem ceeb raw khoom nyob rau hauv sanitizing gel, kuj nce kev nyiam los ntawm biochemical reagent manufacturers.

Hydroxypropyl methylcellulose HPMC yog siv rau hauv tes ntxuav cov gels feem ntau vim nws cov thickening, viscosity thiab permeability. Cov neeg feem coob nyiam cov gels rau cov tshuaj ntxuav tes. Hydroxypropyl methylcellulose HPMC tuaj yeem hloov cov kev daws teeb meem rau hauv cov gels thiab cov gels muaj zog dua thiab siv tau yooj yim dua li cov kua dej. Qhov concentration ntawm Hydroxypropyl methylcellulose HPMC kuj tseem nyob hauv thaj tsam ntawm 0.2% -0.5%. Hydroxypropyl methylcellulose HPMC tuaj yeem ua rau lub tshuab ua kua muaj txiaj ntsig tshwj xeeb thiab cov khoom rheological. Tsuas yog qhov tsis tshua muaj siab heev tuaj yeem ua rau qee qhov tsis txaus ntseeg ntxiv (particles, roj tee, thiab lwm yam) kom ua tiav qhov kev ncua mus tas li.

Nws yog vim nws muaj peev xwm ncua kev kawm ntawv uas Hydroxypropyl methylcellulose HPMC tau siv dav. Tsis tas li ntawd, Hydroxypropyl methylcellulose HPMC siv rau hauv tes ntxuav gel tuaj yeem ua tiav cov txiaj ntsig zoo. Tom qab neutralization thiab ionization ntawm carboxyl pawg, vim kev sib nrig sib repulsion ntawm qhov tsis zoo, cov saw molecular yog dispersed thiab txuas ntxiv, qhia zoo expansion thiab viscosity. Cov yam ntxwv zoo li no ua rau Hydroxypropyl methylcellulose HPMC ua ib qho tseem ceeb raw cov ntaub ntawv rau kev ntxuav tes.

Qhov tseem ceeb tshaj plaws ntawm kev siv cov tshuaj ntxuav tes tsis muaj tshuaj tua kab mob yog tias nws tsis txhob rov ntxuav dua thiab tsis tuaj yeem ntxuav nrog dej, tab sis kuj tuaj yeem ua tiav qhov inhibition thiab tshem tawm cov kab mob tes. Tshwj xeeb tshaj yog nyob rau lub caij ntuj sov, cov kab mob loj hlob sai, tshwj xeeb tshaj yog cov kab mob hauv plab hnyuv, pyogenic cocci, poov xab thiab lwm yam kab mob. Cov tshuaj tua kab mob tseem ceeb hauv cov tshuaj ntxuav tes yog ethanol, lwm cov tshuaj tua kab mob muaj nyob yog tias lawv ua tau zoo, thiab qee qhov yog guanidine. Cov ntsiab lus ntawm tus neeg sawv cev bacteriostatic yog ob peb puas feem pua ​​​​ntawm feem ntau, nrog rau 23% feem ntau, thiab cov ntsiab lus ntawm txhua yam ntawm cov kab mob bacteriostatic kuj muaj cov kev cai meej hauv lub teb chaws tus qauv.

Raws li tus kab mob tshiab kis tau nyob hauv tsev thiab txawv teb chaws, cov khoom siv tshuaj tua kab mob tua kab mob hauv cov khoom luv luv hauv lub sijhawm luv luv, tshwj xeeb tshaj yog thaum tawm mus rau kev ua kom tsis muaj menyuam ntawm tes ntxuav koj txhais tes tsis muaj dej, yog vwm rau nyiag, Hydroxypropyl methylcellulose HPMC yog ib qho ntawm cov khoom xyaw ntawm kua xab npum dawb, ntau lub chaw tsim khoom rau tus nqi nce, ib feem ntawm cov chaw tsim khoom vim tias ntau qhov kev txiav txim tsis tuaj yeem muab cov khoom qub, Txawm li cas los xij, Raws li ib qho ntawm cov tuam ntxhab ntawm Hydroxypropyl methylcellulose HPMC cov khoom lag luam, KIMA tsis tuaj yeem lav cov khoom lag luam ib txwm muaj, tab sis kuj tswj tus nqi tsis nce, uas yog lub chaw tsim khoom tiag tiag ntawm lub siab.
