Ingabe i-HEC yemvelo?

I-HEC ayiwona umkhiqizo wemvelo.Kuyi-polymer yokwenziwa etholakala ku-cellulose, okuyi-polysaccharide eyenzeka ngokwemvelo etholakala ezitshalweni.IHydroxyethyl cellulose HEC iyi-polymer encibilika emanzini esetshenziswa ezinhlelweni ezahlukahlukene, kufaka phakathi njenge-ejenti ejiyayo, i-emulsifier, i-stabilizer, ne-ejenti elengayo.

I-HEC ikhiqizwa ngokusabela kwe-cellulose nge-ethylene oxide, ikhemikhali etholakala ku-petroleum.Lokhu kusabela kudala i-polymer enemvelo ye-hydrophilic (ethanda amanzi), eyenza inyibilike emanzini.I-HEC iyimpushana emhlophe, egeleza mahhala engenaphunga futhi engenambitheki.Ayishi futhi izinzile phezu kwebanga elibanzi lamazinga okushisa namazinga e-pH.

I-HEC isetshenziswa ezimbonini ezahlukahlukene, ezihlanganisa ukudla, ezemithi, izimonyo, nemikhiqizo yokunakekela umuntu.Ekudleni, isetshenziswa njenge-thickener, emulsifier, kanye ne-stabilizer.Kwezemithi, isetshenziswa njenge-ejenti yokumisa kanye ne-tablet binder.Emikhiqizo yezimonyo neyokunakekelwa komuntu siqu, isetshenziswa njenge-thickener kanye ne-stabilizer.

I-HEC ngokuvamile ibhekwa njengephephile ukusetshenziswa ekudleni, emithini yemithi, nasezimonyoni.Igunyazwe ukusetshenziswa e-United States naseYurophu, futhi isohlwini lwe-FDA's Generally Recognised as Safe (GRAS) uhlu.

I-HEC ayiwona umkhiqizo wemvelo, kodwa iyisithako esiphephile nesisebenzayo esisetshenziswa kabanzi ezimbonini eziningi.Iyingxenye ebalulekile yemikhiqizo eminingi, futhi ukusebenzisa kwayo izinto ezihlukahlukene kuyenza ibe isithako esibalulekile sezinhlelo zokusebenza eziningi.
