Ngaba i-hydroxypropyl methylcellulose ikhuselekile?

IHydroxypropyl methylcellulose (HPMC) isetyenziswa ngokubanzi, ikhuselekile, kwaye ingekho ityhefu evela kwiselulosi esetyenziswa kwiinkqubo ezahlukeneyo. Ngumgubo omhlophe, ongenavumba, ongenancasa, kwaye awuthukutheli, onyibilika emanzini abandayo kwaye wenze ijeli xa ushushu. I-HPMC isetyenziswa kumashishini ahlukeneyo, kuquka ukutya, amayeza, kunye neemveliso zokuthambisa.

I-HPMC yi-semi-synthetic polymer ephuma kwi-cellulose, eyipolysaccharide yendalo efumaneka kwizityalo. Yi-non-ionic, i-polymer enyibilikayo emanzini esetyenziswa njenge-ajenti yokuqina, i-stabilizer, i-emulsifier, kunye ne-arhente yokumisa. I-HPMC ikwasetyenziswa njengearhente yokwenza ifilim, ibhinda, kunye nentambiso kwiimveliso ezahlukeneyo.

I-HPMC ithathwa njengekhuselekile ngokubanzi ekutyeni, kumayeza, nakwiimveliso zokuthambisa. Ivunyiwe yi-US Food and Drug Administration (FDA) ukuba isetyenziswe ekutyeni nakwimveliso yamayeza, kwaye ivunyiwe yi-European Union ukuba isetyenziswe ekutyeni, kumayeza, nakwimveliso yokuthambisa. I-HPMC ikwavunyiwe nguMbutho wezeMpilo weHlabathi (i-WHO) ukuba isetyenziswe kwiimveliso zamayeza.

Ngokubhekiselele kukhuseleko, i-HPMC ithathwa njengento engeyona ityhefu kwaye ayicaphukisi. Kuye kwavavanywa kwizifundo zezilwanyana kwaye kwafunyaniswa ukuba ayinayo ityhefu kwaye ayicaphukisi. Kwakhona kuthathwa njengento engeyiyo i-allergenic kunye ne-non-sensitizing.

I-HPMC ikwajongwa njengento enokubola kwaye inobuhlobo nokusingqongileyo. Ayaziwa ukuba iqokelelana kwindawo engqongileyo kwaye ayijongwa njengesisongelo kubomi basemanzini.

Lilonke, i-HPMC yinto ephuma kwiselulosi ekhuselekileyo nengeyotyhefu esetyenziswa kumashishini ahlukeneyo. Ivunyiwe yi-FDA, i-EU, kunye ne-WHO ukuba isetyenziswe ekutyeni, kumayeza, nakwiimveliso zokuthambisa. Ayinatyhefu, ayicaphukisi, ayinayo i-allergenic, kwaye ayivalisi. Iyakwazi ukubola kwaye ihambelana nokusingqongileyo. Ngenxa yezi zizathu, i-HPMC ithathwa njengesithako esikhuselekileyo nesisebenzayo sokusetyenziswa kwiimveliso ezahlukeneyo.
