Umehluko phakathi kwesitashi se-hydroxypropyl kanye ne-hydroxypropylylylym methyl cellulose

I-Hydroxypropyl starch ne-hydroxypropyll methyl celtule Ngenkathi babelana ngokufana okuthile, banomehluko ohlukile ngokwesakhiwo samakhemikhali, izakhiwo, kanye nezicelo. Nalu umehluko omkhulu phakathi kwesitashi se-hydroxypropyll ne-HPMC:

Isakhiwo samakhemikhali:

1. I-Hydroxypropyl Starch:
   • I-Hydroxypropyl starch iyisitashi esilungisiwe esitholwe ukwethula amaqembu we-hydroxypropyl ku-molecule yesitashi.
   • Isitashi yi-polysaccharide ehlanganiswe ama-glucose amayunithi axhumene ndawonye ngamabhondi e-glycosidic. I-Hydroxypropylation ifaka ukufaka esikhundleni samaqembu e-hydroxl (-oh) ku-molecule yesitashi nge-hydroxypropyllopp (-ch2chohchch3).
2. I-Hydroxypropyl methyl cellulose (HPMC):
   • I-HPMC i-ether eguquliwe etholwe ngokuthola ukwethula zombili i-hydroxypropyl kanye namaqembu we-methyl ku-molecule ye-cellulose.
   • I-Cellulose iyi-polysaccharide ehlanganiswe ama-glucose amayunithi axhumene ndawonye ngu-β (1 → 4) amabhondi e-glycosic. I-Hydroxyproppyly yethula amaqembu we-hydroxypropyll (-ch2chohchch3), ngenkathi i-methylation yethula amaqembu we-methyl (-ch3) e-cellulose backbone.

Izakhiwo:

1. I-Solubity:
   • I-Hydroxypropyl starch imvamisa iyancibilika emanzini ashisayo kepha ingakhombisa ukugcwala okulinganiselwe emanzini abandayo.
   • I-HPMC iyanyibilika kuwo womabili amanzi abandayo nawashisayo, akha izixazululo ezicacile, ezibonakalayo. I-solubity ye-HPMC incike ngezinga lokufaka esikhundleni (DS) kanye nesisindo se-polymer.
2. I-Viscosity:
   • I-Hydroxypropyl starch ingakhombisa izakhiwo ze-viscosity, kepha ukubonakala kwayo kuvame ukwehla uma kuqhathaniswa ne-HPMC.
   • I-HPMC yaziwa ngokuqina kwayo okuhle kakhulu nokubona izinto eziguqukayo. I-viscosity yezixazululo ze-HPMC ingashintshwa ngokuhlukahlukana kwe-polymer, i-DS kanye nesisindo se-molecular.

Izicelo:

1. Ukudla nemithi:
   • I-Hydroxypropyl starch ivame ukusetshenziswa njenge-sikhulu, i-stabilizer, ne-ejenti yokudla emikhiqizweni yokudla efana namasobho, amasoso, kanye nama-dessert. Kungase futhi kusetshenziswe ekwakhiweni kwemithi.
   • I-HPMC isetshenziswa kabanzi ekudleni, emikhakheni, kanye nezimonyo njenge-smighter, emulsifier, stabilizer, ifilimu yangaphambili, ne-ejenti yokukhishwa kwefilimu. Kuvame ukutholakala emikhiqizweni efana namathebulethi, ama-ointmentions, okhilimu kanye nezinto zokunakekelwa komuntu.
2. Izinto zokwakha nezisezakhiweni:
   • I-HPMC isetshenziswa kabanzi embonini yezokwakha njengezengezo emikhiqizweni esekwe kasikiselo efana nezithasiselo zamathayili, izidakamizwa, ukuhumusha kanye nezinhlekelele. Inikeza ukugcinwa kwamanzi, ukusebenziseka, ukunamathela, nokusebenza okuthuthukile kulezi zinhlelo zokusebenza.

Isiphetho:

Ngenkathi womabili i-hydroxypropylyls ne-HPMC ama-polysaccharides aguqulwe ngokusebenza okufanayo, anezinhlaka ezihlukile zamakhemikhali, izakhiwo nezinhlelo zokusebenza. Isitashi se-Hydroxypropyl sisetshenziswa ngokuyinhloko kuzinhlelo zokusebenza zokudla kanye nemithi, kanti i-HPMC ithola ukusetshenziswa okubanzi ekudleni, emikhakheni, izimonyo kanye nezinto zokwakha. Ukuzikhethela phakathi kwe-Hydroxypropyls Starch ne-HPMC kuncike kwizidingo ezithile zohlelo lokusebenza oluhlosiwe.
