Hydroxypropyl Methylcellulose (HPMC) Qib Rau Tes Sanitizer

Hydroxypropyl Methylcellulose (HPMC) Qib Rau Tes Sanitizer

Hydroxypropyl Methylcellulose (HPMC) yog cov khoom siv polymer dav siv hauv kev lag luam tshuaj, tshuaj pleev ib ce, thiab kev saib xyuas tus kheej vim nws cov khoom tshwj xeeb xws li thickening, emulsifying, stabilizing, thiab dej tuav. Nyob rau hauv xyoo tas los no, HPMC tau txais kev saib xyuas tseem ceeb raws li cov khoom tseem ceeb hauv cov tshuaj ntxuav tes vim nws lub peev xwm los txhim kho kev ua tau zoo, kev ntxhib los mos, thiab kev ua haujlwm tag nrho ntawm cov khoom.

Thaum nws los txog rau cov tshuaj ntxuav tes, kev xaiv cov qib tsim nyog ntawm HPMC yog qhov tseem ceeb los xyuas kom meej qhov kev ua tau zoo thiab kev ruaj ntseg ntawm cov qauv. Cov khoom tseem ceeb ntawm HPMC uas cuam tshuam rau kev siv tshuaj ntxuav tes yog viscosity, particle loj, thiab cov ntsiab lus methoxy thiab hydroxypropyl.

Feem ntau, qib siab viscosity ntawm HPMC yog qhov zoo dua rau cov qauv tshuaj ntxuav tes kom ntseeg tau tias cov thickening txaus thiab txhim kho kev sib kis. Lub viscosity ntawm HPMC tuaj yeem nyob ntawm qhov qis mus rau qhov siab, nrog rau kev xaiv nyob ntawm cov qauv tsim tshwj xeeb thiab cov ntawv thov. Rau cov tshuaj ntxuav tes, viscosity qib ntawm 100,000-200,000 cps feem ntau yog siv.

Qhov loj me me ntawm HPMC yog lwm qhov tseem ceeb rau kev tsim cov tshuaj ntxuav tes. Qhov loj me me yog qhov zoo dua los xyuas kom meej sai sai thiab tawg hauv formulation. Ib qho me me ntawm 100 mesh lossis finer feem ntau pom zoo rau kev siv tshuaj ntxuav tes.

Nyob rau hauv cov ntsiab lus ntawm methoxy thiab hydroxypropyl cov ntsiab lus, qhov zoo tagnrho piv ntawm ob lub ntsiab yog nyob ntawm cov qauv tsim thiab cov khoom xav tau. Feem ntau, cov ntsiab lus hydroxypropyl ntau dua ua rau cov dej tuav tau zoo dua thiab txhim kho gelation zog, thaum cov ntsiab lus methoxy ntau dua tuaj yeem txhim kho cov yeeb yaj kiab tsim thiab adhesion. Rau kev siv tshuaj ntxuav tes, cov ntsiab lus hydroxypropyl ntawm 9-12% thiab cov ntsiab lus methoxy ntawm 28-32% feem ntau yog siv.

Nws tseem yog ib qho tseem ceeb uas yuav tau xav txog qhov zoo thiab purity ntawm HPMC siv nyob rau hauv cov tshuaj ntxuav tes formulations. HPMC yuav tsum tsis txhob muaj impurities thiab cov kab mob uas tuaj yeem cuam tshuam rau kev ua tau zoo thiab kev nyab xeeb ntawm cov khoom. Nws raug pom zoo los ntawm HPMC los ntawm cov tuam txhab muaj npe nrov uas muaj cov ntaub ntawv pov thawj ntawm kev tsim cov khoom zoo uas ua tau raws li qhov yuav tsum tau ua.

Zuag qhia tag nrho, kev xaiv ntawm qib tsim nyog ntawm HPMC yog qhov tseem ceeb rau kev ua haujlwm thiab kev ruaj ntseg ntawm cov tshuaj ntxuav tes. Yam xws li viscosity, particle loj, thiab methoxy thiab hydroxypropyl cov ntsiab lus yuav tsum tau ua tib zoo txiav txim siab los xyuas kom meej qhov kev ua tau zoo thiab kev nyab xeeb ntawm cov khoom.
