Ko hydroxypropyl methylcellulose yakachengeteka here?

Hydroxypropyl methylcellulose (HPMC) inoshandiswa zvakanyanya, yakachengeteka, uye isiri-chepfu seruseru inobuda iyo inoshandiswa mumhando dzakasiyana dzekushandisa. Ihwo hupfu hwakachena, husina kunhuwa, husina kunaka, uye husingasviki hupfu hunonyungudika mumvura inotonhora uye hunoita gel kana uchipisa. HPMC inoshandiswa mumaindasitiri akasiyana siyana, kusanganisira chikafu, mishonga, uye zvigadzirwa zvekuzora.

HPMC isemi-synthetic polymer inotorwa kubva muselulosi, inova yakasikwa polysaccharide inowanikwa muzvirimwa. Iyo isiri-ionic, mvura-inonyungudika polima iyo inoshandiswa seyakakora mumiriri, stabilizer, emulsifier, uye inomisa mumiriri. HPMC inoshandiswawo semugadziri wemufirimu-mugadziri, binder, uye lubricant mune zvakasiyana zvigadzirwa.

HPMC inowanzoonekwa yakachengeteka kushandiswa mukudya, mishonga, uye zvigadzirwa zvekuzora. Inotenderwa neUS Food and Drug Administration (FDA) kuti ishandiswe muchikafu uye zvigadzirwa zvemishonga, uye zvakare inotenderwa neEuropean Union kuti ishandiswe muchikafu, mishonga, uye zvigadzirwa zvekuzora. HPMC inobvumidzwawo neWorld Health Organisation (WHO) kuti ishandiswe muzvigadzirwa zvemishonga.

Panyaya yekuchengeteka, HPMC inoonekwa seisina chepfu uye isingagumbure. Yakaedzwa muzvidzidzo zvemhuka uye yakawanikwa isina chepfu uye isingatsamwisi. Iyo zvakare inoonekwa seisina-allergenic uye isinganzwisisike.

HPMC inoonekwawo seyakaomeswa uye ine hushamwari kwezvakatipoteredza. Hazvizivikanwi kuunganidza mumhoteredzo uye hazvirangarirwi kuva tyisidziro kuupenyu hwomumvura.

Pakazere, HPMC ndeye yakachengeteka uye isiri-chepfu cellulose derivative iyo inoshandiswa mumaindasitiri akasiyana. Inotenderwa neFDA, EU, uye WHO kuti ishandiswe mukudya, mishonga, uye zvigadzirwa zvekuzora. Haina-chepfu, isingatsamwisi, haina-allergenic, uye isinganzwisisi. Iyo zvakare ine biodegradable uye inoshamwaridzana nenharaunda. Nezvikonzero izvi, HPMC inoonekwa sechinhu chakachengeteka uye chinoshanda chekushandisa mumhando dzakasiyana dzezvigadzirwa.
