HPMC F50 yog hydroxypropyl methylcellulose (HPMC) khoom tsim los ntawm Kima Chemical. Nws yog dawb, dawb-ntws hmoov uas tsis muaj ntxhiab, tsis qab, thiab tsis muaj tshuaj lom. Nws yog ntau yam polymer uas tuaj yeem siv rau ntau yam kev siv, suav nrog zaub mov thiab dej haus, tshuaj, thiab khoom siv tshuaj pleev ib ce. HPMC F50 yog ib qho cellulose ether uas yog tsim los ntawm cov saw ntev ntawm cov piam thaj molecules. Nws yog non-ionic, dej-soluble polymer uas yog muab los ntawm cellulose, ib txwm tshwm sim polysaccharide pom nyob rau hauv cov nroj tsuag. Cov pab pawg hydroxypropyl yog ntxiv rau cov cellulose molecule kom nws muaj ntau dua ntawm solubility hauv dej. Qhov no ua rau nws yog ib qho khoom siv zoo tshaj plaws rau kev siv hauv cov khoom noj thiab dej haus, vim nws tuaj yeem yooj yim yaj hauv dej lossis lwm yam kua. HPMC F50 yog siv nyob rau hauv ntau yam kev siv, nrog rau cov thickener, stabilizer, emulsifier, thiab suspending agent. Nws yog feem ntau siv hauv cov khoom noj khoom haus thiab dej haus los txhim kho kev ntxhib los mos, txhim khu tsw, thiab ua kom lub neej txee. Hauv cov tshuaj, nws yog siv los txhim kho cov solubility thiab stability ntawm cov khoom xyaw nquag thiab txhim kho bioavailability ntawm cov tshuaj. Nyob rau hauv cov tshuaj pleev ib ce, nws yog siv raws li ib tug thickener thiab emulsifier los txhim kho cov kev ntxhib los mos thiab stability ntawm cream thiab lotions. HPMC F50 yog cov khoom siv ntau yam uas tuaj yeem siv rau ntau yam kev siv. Nws yog cov khoom muaj kev nyab xeeb thiab siv tau zoo uas tau siv dav hauv cov khoom noj, tshuaj, thiab cov khoom kom zoo nkauj. Nws yog ib qho zoo thickener, stabilizer, emulsifier, thiab tshem tawm tus neeg sawv cev uas tuaj yeem txhim kho kev ntxhib los mos, tsw, thiab txee lub neej ntawm cov khoom. Nws kuj yog ib qho uas tsis yog-ionic, dej-soluble polymer uas yooj yim rau yaj hauv dej los yog lwm yam kua.
