Kodi hydroxypropyl methylcellulose ndi yotetezeka?

Hydroxypropyl methylcellulose (HPMC) ndi yochokera ku cellulose yomwe imagwiritsidwa ntchito kwambiri, yotetezeka, komanso yopanda poizoni yomwe imagwiritsidwa ntchito m'njira zosiyanasiyana.Ndi ufa woyera, wosanunkhiza, wosakoma, komanso wosapsa mtima womwe umasungunuka m'madzi ozizira ndipo umapanga gel pamene watenthedwa.HPMC imagwiritsidwa ntchito m'mafakitale osiyanasiyana, kuphatikiza chakudya, mankhwala, ndi zodzikongoletsera.

HPMC ndi semi-synthetic polima yochokera ku cellulose, yomwe ndi polysaccharide yachilengedwe yomwe imapezeka muzomera.Ndi polima yopanda ionic, yosungunuka m'madzi yomwe imagwiritsidwa ntchito ngati thickening agent, stabilizer, emulsifier, ndi suspending agent.HPMC imagwiritsidwanso ntchito ngati chopangira filimu, binder, ndi mafuta muzinthu zosiyanasiyana.

HPMC nthawi zambiri imawonedwa ngati yotetezeka kuti igwiritsidwe ntchito muzakudya, zamankhwala, ndi zodzikongoletsera.Imavomerezedwa ndi US Food and Drug Administration (FDA) kuti igwiritsidwe ntchito muzakudya ndi mankhwala, komanso imavomerezedwa ndi European Union kuti igwiritsidwe ntchito muzakudya, zamankhwala, ndi zodzikongoletsera.HPMC imavomerezedwanso ndi World Health Organisation (WHO) kuti igwiritsidwe ntchito muzamankhwala.

Pankhani ya chitetezo, HPMC imatengedwa kuti ndi yopanda poizoni komanso yosakwiyitsa.Zayesedwa m'maphunziro a nyama ndipo zidapezeka kuti sizowopsa komanso zosakhumudwitsa.Zimaganiziridwanso kuti ndizopanda allergenic komanso zopanda mphamvu.

HPMC imawonedwanso kuti ndi yosawonongeka komanso yosamalira zachilengedwe.Sizikudziwika kuti zimawunjikana m’chilengedwe ndipo sizimaonedwa kuti n’zoopsa pa zamoyo za m’madzi.

Ponseponse, HPMC ndiyochokera ku cellulose yotetezeka komanso yopanda poizoni yomwe imagwiritsidwa ntchito m'mafakitale osiyanasiyana.Imavomerezedwa ndi FDA, EU, ndi WHO kuti igwiritsidwe ntchito muzakudya, mankhwala, ndi zodzikongoletsera.Ndizopanda poizoni, zosakwiyitsa, zopanda allergenic, komanso zosalimbikitsa.Komanso ndi biodegradable komanso zachilengedwe.Pazifukwa izi, HPMC imatengedwa kuti ndi yotetezeka komanso yothandiza kuti igwiritsidwe ntchito pazinthu zosiyanasiyana.
