Kodi hypromellose ndi hydroxypropyl cellulose ndizofanana?

Ayi, hypromellose ndi hydroxypropyl cellulose sizofanana.

Hypromellose, yemwenso amadziwika kuti hydroxypropyl methylcellulose (HPMC), ndi semi-synthetic, inert, viscoelastic polima yomwe imagwiritsidwa ntchito ngati mafuta a ophthalmic, excipient pakamwa, binder piritsi, komanso filimu yakale. Ndiwochokera ku cellulose ndipo amapangidwa ndi mayunitsi obwerezabwereza a shuga wa shuga. Hypromellose imagwiritsidwa ntchito muzamankhwala osiyanasiyana, zodzoladzola, ndi zakudya, ndipo nthawi zambiri imadziwika kuti ndi yotetezeka (GRAS) ndi US Food and Drug Administration (FDA).

Hydroxypropyl cellulose (HPC) ndi semi-synthetic polima yochokera ku cellulose. Amapangidwa ndi mayunitsi obwerezabwereza a shuga wa shuga ndipo amagwiritsidwa ntchito ngati thickening, stabilizer, ndi kuyimitsa wothandizira pazinthu zosiyanasiyana. HPC nthawi zambiri imawonedwa ngati yotetezeka (GRAS) ndi US Food and Drug Administration (FDA).

Ngakhale kuti hypromellose ndi hydroxypropyl cellulose zimachokera ku cellulose, sizili zofanana. Hypromellose ndi yochokera ku cellulose yomwe ili ndi magulu a hydroxypropyl, pomwe hydroxypropyl cellulose ndi polima wa cellulose yomwe ili ndi magulu a hydroxypropyl. Hypromellose amagwiritsidwa ntchito ngati lubricant ophthalmic, oral excipient, tablet binder, ndi filimu yakale, pamene hydroxypropyl cellulose imagwiritsidwa ntchito ngati thickening agent, stabilizer, ndi suspending agent.
