Hydroxypropyl Methyl Cellulose (HPMC)
Hydroxypropyl methyl cellulose, ua kom yooj yim rau propyl methyl cellulose (HPMC hydroxypropylmethylcellulose, abbreviation), nws yog mus rau ntau yam sib xyaw uas tsis yog-ionic cellulose ether.Nws yog semi-synthetic, inactive, viscoelastic polymer feem ntau siv nyob rau hauv ophthalmology ua ib tug lubricant, los yog raws li ib tug excipient los yog excipient nyob rau hauv lub qhov ncauj tshuaj, feem ntau pom nyob rau hauv ntau yam khoom.Hydroxypropyl cellulose tuaj yeem siv los ua khoom noj khoom haus, emulsifier, thickener, raug tshem tawm tus neeg sawv cev thiab tsiaj gelatin hloov.

Hydroxypropyl Methylcellulose HPMC/HEC/MHPC
Hydroxypropyl methylcellulose, tseem hu ua hypromellose, yog ib qho ntawm cov uas tsis yog-ionic cellulose tov ethers.Nws yog ib tug semi-synthetic, inactive, viscoelastic polymer, feem ntau siv los ua lubricant nyob rau hauv ophthalmology, los yog raws li ib tug excipient los yog excipient nyob rau hauv lub qhov ncauj tshuaj.
Nws yog soluble hauv dej thiab qee cov kuab tshuaj, xws li ethanol / dej, propanol / dej hauv qhov tsim nyog.Cov tshuaj aqueous muaj cov dej num saum npoo av.High transparency thiab ruaj khov ua haujlwm.Cov khoom sib txawv ntawm cov khoom muaj qhov sib txawv gel kub thiab solubility hloov nrog viscosity.Qhov qis dua qhov viscosity, qhov ntau dua qhov solubility.Cov kev qhia tshwj xeeb ntawm HPMC muaj qhov sib txawv.Kev sib cais ntawm HPMC hauv dej tsis cuam tshuam los ntawm pH.
