Hydroxypropyl Methyl Cellulose (HPMC)
Hydroxypropyl methyl cellulose, faafaigofie le propyl methyl cellulose (HPMC hydroxypropylmethylcellulose, faapuupuuga), e tatau ona auai i se ituaiga o fefiloi non-ionic cellulose ether.Ose polymer semi-synthetic, inactive, viscoelastic e masani ona fa'aogaina i le ophthalmology e fai ma lubricant, po'o se mea e fa'aoga ai i vaila'au tu'u gutu, e masani ona maua i le tele o ituaiga o oloa.Hydroxypropyl cellulose e mafai ona faʻaaogaina e fai ma meaʻai faaopoopo, emulsifier, mafiafia, sui faʻamalolo ma sui gelatin manu.

Hydroxypropyl Methylcellulose HPMC/HEC/MHPC
O le Hydroxypropyl methylcellulose, lea e lauiloa foi o le hypromellose, o se tasi o ethers non-ionic cellulose fefiloi. O se semi-synthetic, inactive, viscoelastic polymer, e masani ona faʻaaogaina e fai ma lubricant i ophthalmology, poʻo se mea faʻapitoa poʻo mea faʻapitoa i vailaʻau tuʻu.
E solu i le vai ma nisi solvents, pei ole ethanol/vai, propanol/vai i vaega talafeagai.O le vaifofo vai o lo'o i ai gaioiga i luga.Malamalama maualuga ma mautu le faatinoga.O faʻamatalaga eseese o oloa e eseese le vevela gel ma suiga solubility ma le viscosity.O le maualalo o le viscosity, o le tele o le solubility.O faʻamatalaga eseese o le HPMC e eseese faʻatinoga.Ole fa'amavae ole HPMC ile vai e le a'afia ile pH.
