I-HPMC ye-APPMC kunye ne-hydroxypropoxy

I-HPMC (i-hydroxyproplopythylcelcelcelcelcelcelcelcelcelcelose) i-selsulose i-selsulose isetyenziswa njenge-binder, i-thickener kunye ne-mulsifier kwimizi-mveliso eyahlukeneyo. Ikwasetyenziswa njengokuthanda kakhulu kwiindawo zamachiza. I-HPMC yi-isohlwayo yamanzi, i-polymer ye-polymer enokuthi ilungiswe ngokwahluka kwenqanaba lokufakwa endaweni ye-hydroxypropoxy kunye ne-mazantsi.

Ukuveliswa kwe-HPMC kubandakanya ukuthantamisa kwe-seluplose ne-methyl chloride kunye ne-proplenene oxide. Inqanaba le-AFTIBSY kunye ne-hydroxypropoxy inokulawulwa ngexesha lenkqubo yokuqulunqa, echaphazela ipropathi yokugqibela yemveliso.

Ipropathi ebalulekileyo ye-HPMC kukukwazi kwayo ukwenza i-galls. I-HPMC GELs isetyenziswa ngokubanzi kwishishini lokutya njengamanzi amakhulu kunye nokuzinzisa. Zikwasetyenziswa njengeearhente zokukhupha kwiiarhente zamachiza ukulawula inqanaba apho ichiza likhutshwa khona. Ipropathi ye-gel ye-HPMC inokutshintshwa ngokuhlengahlengiswa kwenqanaba lokufakwa endaweni ye-Hydroxypropoxy kunye namaqela e-AFGISY.

Enye ipropathi ebalulekileyo ye-HPMC kukomeleza kwayo. I-HPMC inyibilikiswe ngokulula emanzini, isenza ukuba ibe yeyona nto ifanelekileyo. Ikwahambelana nezinye iimfuno ezininzi ezisetyenziswa kumzi-mveliso wamayeza, zivumela ukwenziwa kweziyobisi ngokulula.

I-HPMC ikwasetyenziswa kumzi mveliso wokwakha njenge-binder kunye ne-tickener kwiimveliso ezisekwe kwisamente. Ukongeza i-HPMC ukuya kumxube wesamente kuphucula ukusebenza kwayo kwaye kunciphisa i-shrinkage kunye nokuqhekeka. Ikwaphucula iipropathi zokugcina amanzi kumxube wesamente, ngokwenza oko kuphuculwe ukuseta kunye namandla emveliso ephilisiweyo.

Kumzi-mveliso wokhathalelo lobuqu, i-HPMC isetyenziswa njenge-thi choner kunye ne-stabilizer kwi-cosmetics kunye neemveliso zononophelo lomntu. Amandla ayo okwenza i-gel-efana nejeli iyakuvumela ukuba uzinze uzinze iziciko kunye nokuphucula ukwenziwa kweekhrim kunye nezilonda.

I-HPMC yinto yezinto ezahlukeneyo ezinoluhlu olubanzi lwezicelo kumashishini ahlukeneyo. Iipropathi zayo zinokulungelelaniswa ngokuhlengahlengiswa kwenqanaba lokufakwa endaweni ye-Hydroxypropoxy kunye ne-mayiptusty. Inyibilikiswa ngokulula emanzini, isenza ukuba ibe yinto efanelekileyo yamayeza. Ukukwazi kwayo ukwenza i-gals zenza ukuba ibe luncedo njenge-thi chunger kunye nokuzinza ekutyeni, ukhathalelo lobuqu kunye namashishini okwakha. Ukongeza i-HPMC ukuya kumxube wesamente kuphucula iindlela zayo zokugcina kunye nokugcina amanzi, kwenza ukuba bomelele kwaye bomelele ngakumbi. Lilonke, i-HPMC yinto ebalulekileyo eqhubekayo yokufumana izicelo ezintsha kumashishini ahlukeneyo, ukuphucula umgangatho weemveliso kunye neenkqubo.
