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 avea o se mea 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 atu o 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 e 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 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.
