HPMC k15 yog dab tsi?

HPMC K15 yog qib hydroxypropyl methylcellulose (HPMC) qib ntawm cellulose ether, nrog viscosity ntau 12.0-18.0, uas yog ib hom dej-soluble polymeric khoom. Nws yog cov hmoov dawb, tsis muaj ntxhiab, tsis qab, uas yog siv los ua tus neeg sawv cev thickening, stabilizer, thiab emulsifier hauv ntau yam khoom. HPMC K15 yog ib qho uas tsis yog-ionic cellulose ether, txhais tau tias nws tsis muaj ib pawg ionic thiab yog li ntawd tsis-reactive. Nws yog siv rau hauv ntau hom kev siv, suav nrog zaub mov, tshuaj, tshuaj pleev ib ce, thiab cov khoom lag luam.

HPMC K15 yog qib siab molecular hnyav ntawm HPMC, lub ntsiab lus nws yog tsim los ntawm cov saw ntev ntawm cov molecules. Qhov no ua rau nws yog ib qho zoo tagnrho thickening tus neeg sawv cev, raws li nws muaj peev xwm tsim ib tug gel zoo li qauv thaum tov nrog dej. Cov qauv zoo li gel no ua rau kom muaj viscosity ntawm cov tshuaj, uas ua rau nws ua haujlwm zoo thickening. HPMC K15 kuj yog ib qho zoo emulsifier, txhais tau tias nws tuaj yeem pab kom ruaj khov ntawm cov roj thiab dej, tiv thaiv lawv los ntawm kev sib cais. Qhov no ua rau nws muaj txiaj ntsig zoo hauv ntau yam khoom, xws li cream, lotions, thiab tshuaj pleev.

HPMC K15 yog cov khoom siv nyab xeeb thiab tsis muaj tshuaj lom, ua rau nws tsim nyog siv rau hauv cov khoom noj thiab tshuaj. Nws kuj tau pom zoo los ntawm FDA rau kev siv cov khoom noj thiab tshuaj pleev ib ce, thiab suav tias yog kev nyab xeeb rau tib neeg noj. HPMC K15 kuj yog ib qho khoom siv ib puag ncig, vim nws yog biodegradable thiab tsis muaj tshuaj lom.

HPMC K15 yog cov khoom siv ntau yam uas tuaj yeem siv rau ntau yam kev siv. Nws yog ib tug zoo thickening neeg sawv cev, emulsifier, thiab stabilizer, ua rau nws pab tau nyob rau hauv ntau yam khoom. Nws tseem muaj kev nyab xeeb, tsis muaj tshuaj lom, thiab ib puag ncig tus phooj ywg, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev siv khoom noj, tshuaj, thiab tshuaj pleev ib ce.
