IHypromellose 2208 kunye ne-2910

I-Hypromellose, eyaziwa ngokuba yi-hydroxypropyl methylcellulose (HPMC), i-ether ye-cellulose engeyona inetyhefu kunye ne-non-ionic esetyenziswa kwizicelo ezahlukeneyo, kubandakanywa amayeza, izimonyo kunye neemveliso zokutya. I-HPMC ifumaneka kuluhlu lwamabakala, kuquka i-Hypromellose 2208 kunye ne-2910, eneempawu ezahlukeneyo kunye nokusetyenziswa.

I-Hypromellose 2208 libakala eliphantsi le-viscosity ye-HPMC edla ngokusetyenziswa njenge-binder, i-thickener, kunye nefilimu yangaphambili kumachiza. Ihlala isetyenziswe kwiingubo zethebhulethi, apho ibonelela ngokugudileyo, i-glossy surface kwaye iphucula ukuzinza kwethebhulethi. I-Hypromellose 2208 iphinda isetyenziswe kwi-ophthalmic formulations, apho isebenza njenge-lubricant kwaye iphucula i-viscosity yokuqulunqwa.

IHypromellose 2910 libakala eliphezulu le-viscosity ye-HPMC esetyenziswa njenge-thickener, binder, kunye ne-emulsifier kuluhlu lwezicelo. Kumayeza, isoloko isetyenziswa njenge-arhente ekhutshwayo, njengoko ikhupha kancinci isithako esisebenzayo ekuhambeni kwexesha. I-Hypromellose 2910 nayo isetyenziselwa izimonyo, apho inika umphumo wokuqina, iphucula ukuzinza kwe-emulsions, kwaye iphucula ukuthungwa kwemveliso.

Isishwankathelo, i-Hypromellose 2208 kunye ne-2910 ngamabakala amabini e-HPMC aneempawu ezahlukeneyo kunye nokusetyenziswa. I-Hypromellose 2208 yibakala eliphantsi le-viscosity elisetyenziswa kumachiza, ngelixa i-Hypromellose 2910 inqanaba eliphezulu le-viscosity elisetyenziswa kumayeza, izithambiso, kunye nezinye izicelo.
