O le a le mea e fai mai ai le hydroxypropyl methylcellulose?

Hydroxypropyl methylcellulose (HPMC) o se polymer gaosia, solu vai e maua mai cellulose. O se paʻepaʻe, e leai se manogi, e leai se tofo e masani ona faʻaaogaina e fai ma sui mafiafia, emulsifier, ata tifaga muamua, ma faʻamautu i le tele o alamanuia, e aofia ai vailaʻau, meaʻai, mea teuteu, ma le fausiaina.

O le HPMC e faia e ala i le taliina o le cellulose i le propylene oxide ma le methyl chloride. O le Cellulose o se polysaccharide o le vaega autu lea o puipui o laau toto ma o le faʻalapotopotoga sili ona tele i luga ole lalolagi. O le propylene oxide o se fa'aputu fa'aola fa'atasi ma le fua fa'atatau CH3CHCH2O. Methyl chloride ose kasa e leai ni lanu, e mu ma se manogi suamalie.

O le tali a le cellulose ma le propylene oxide ma le methyl chloride e mafua ai le faʻavaeina o vaega hydroxypropyl, o loʻo faʻapipiʻi i molelaʻau cellulose. O lenei faiga e taʻua o le hydroxypropylation. O vaega o le hydroxypropyl e fa'ateleina ai le solubility o le cellulose i le vai, ma fa'afaigofie ai ona fa'aoga i le tele o fa'aoga.

HPMC o loʻo faʻaaogaina lautele i le falemaʻi vailaʻau e avea o se mea e fusifusia, faʻaleagaina, ma faʻamalolo le tumau i papa ma capsules. E faʻaaogaina foi e avea o se mafiafia ma emulsifier i kulimi ma lotions, ma pei o se ata tifaga muamua i matau mata. I totonu o meaʻai, e faʻaaogaina e avea o se mafiafia, faʻamautu, ma emulsifier i sosi, laei, ma isi meaʻai. I totonu o le fale faufale, e faʻaaogaina e fai ma fusi i totonu o le sima ma le sima, ma o se vai faʻafefeteina mo puipui ma fola.

O le HPMC ose mea saogalemu ma e le o'ona ua fa'atagaina e le US Food and Drug Administration (FDA) mo le fa'aogaina i mea'ai, vaila'au, ma mea teuteu. Ua fa'atagaina fo'i e le Iuni a Europa (EU) mo le fa'aogaina i mea'ai ma vaila'au.
