I-Hydroxyethylcellulose vs carbomer

IHydroxyethylcellulose (HEC) kanye ne-carbomer ama-polymer amabili asetshenziswa kakhulu embonini yokunakekelwa komuntu siqu. Zinezakhiwo ezahlukene zamakhemikhali kanye nezakhiwo, ezizenza zifaneleke izinhlelo zokusebenza ezahlukene.

I-HEC iyipolymer engokwemvelo, encibilika emanzini etholakala ku-cellulose. Ivamise ukusetshenziswa njenge-thickener, emulsifier, kanye ne-stabilizer emikhiqizweni ehlukahlukene yokunakekelwa komuntu siqu njengama-shampoos, ama-conditioner, nokugeza umzimba. I-HEC yaziwa ngokuhambisana kwayo okuphezulu nezinye izithako kanye nekhono layo lokuhlinzeka ukuthungwa okubushelelezi nokukhilimu ekwakhiweni. Iyaziwa nangokucaca kwayo kahle kanye nobuthi obuphansi.

I-Carbomer, ngakolunye uhlangothi, iyi-polymer yokwenziwa, enesisindo samangqamuzana aphezulu evame ukusetshenziswa njenge-ejenti yokuqina emikhiqizweni ehlukahlukene yokunakekelwa komuntu siqu njengama-gel kanye nama-lotions. Isebenza kahle kakhulu ekuqiniseni nasekuqiniseni ukwakheka, futhi inganikeza izinga eliphezulu lokucaca nokumiswa emkhiqizweni oqediwe. I-Carbomer yaziwa nangokulawula kwayo okuhle kakhulu kwe-viscosity nekhono lokuthuthukisa ukusabalala kwemikhiqizo.

Omunye umehluko omkhulu phakathi kwe-HEC ne-carbomer ukuncibilika kwamanzi. I-HEC incibilika kakhulu emanzini, kuyilapho i-carbomer idinga ukungathathi hlangothi nge-alkaline ejenti efana ne-triethanolamine noma i-sodium hydroxide ukuze ibe namanzi ngokugcwele futhi ishube. Ukwengeza, i-HEC yaziwa ngokuzwela kwayo okuphansi ku-pH kanye noshintsho lokushisa, kuyilapho i-carbomer ingathinteka izinguquko ku-pH nezinga lokushisa.

Kafushane, i-HEC ne-carbomer yizinhlobo ezimbili ezihlukene zama-polymers anezakhiwo ezihlukile kanye nezicelo. I-HEC iyi-polymer yemvelo, encibilika emanzini evame ukusetshenziswa njenge-thickener ne-emulsifier, kuyilapho i-carbomer iyi-polymer yokwenziwa, enesisindo samangqamuzana aphezulu esebenza kahle kakhulu ekujikeni nasekuqiniseni ukwakheka. Ukukhethwa kwe-polymer kuncike ezidingweni ezithile kanye nezakhiwo zokubunjwa.
