Yintoni i-hydroxyethyl cellulose?

I-Hydroxyethyl cellulose (HEC) yipolymer enyibilikayo emanzini ephuma kwi-cellulose, i-polysaccharide yendalo efumaneka kwizityalo. I-HEC idalwe ngokuguqulwa kwe-cellulose ngokongezwa kwamaqela e-hydroxyethyl, afakwe kwiiyunithi ze-glucose ze-molecule ye-cellulose. Olu hlengahlengiso lutshintsha iipropathi zeselulosi kwaye luyenze ibe luncedo kwiintlobo ngeentlobo zezicelo, ezinjengokutya, izinto zokuthambisa, kunye namashishini axuba amayeza.

I-HEC i-polymer eguquguqukayo kakhulu, kunye noluhlu lwee-molecular weights kunye needigri zokutshintshwa, ezimisela iimpawu zayo, ezifana nokunyibilika kwayo, i-viscosity, kunye ne-gelation. Iqondo lokutshintshwa ngumlinganiselo wenani lamaqela e-hydroxyethyl aqhotyoshelwe kwiyunithi nganye ye-glucose ye-molecule ye-cellulose, kwaye inokuqala ukusuka kwi-1 ukuya kwi-3, kunye needigri eziphezulu ezibonisa inani elikhulu lamaqela e-hydroxyethyl.

I-HEC isetyenziswa kwiimveliso ezahlukeneyo njenge-thickener, stabilizer, kunye ne-binder. Ingasetyenziselwa ukunyusa i-viscosity yokwenziwa kolwelo, ukuphucula ukuthungwa kunye nomlomo weemveliso zokutya, kunye nokuphucula ukuzinza kwe-emulsions. Kumashishini amayeza, i-HEC isetyenziswa njenge-binder kwiipilisi, njenge-thickener ye-topical formulations, kunye ne-arhente yokukhululwa okuqhubekayo kwiinkqubo zokuhanjiswa kweziyobisi.

Enye yezona zinto zibalulekileyo ze-HEC kukukwazi ukwenza iijeli emanzini. Xa i-HEC ichithwe emanzini, inokwenza i-gel ngokusebenzisa inkqubo eyaziwa ngokuba yi-hydration. Inkqubo ye-gelation ixhomekeke kwiqondo lokutshintshwa, ubunzima be-molecular, kunye nokugxininiswa kwe-HEC kwisisombululo. Inkqubo ye-gelation ye-HEC inokulawulwa ngokuhlengahlengiswa kwezi parameters, okwenza kube luncedo kwiintlobo ezahlukeneyo zezicelo.

I-HEC isetyenziswa ngokuqhelekileyo kushishino lokutya njengento etyebisayo kunye nokuzinzisa kwiimveliso ezifana neesosi, iilokhwe, kunye neesuphu. Inokuphucula ukuthungwa kunye nokuvakala komlomo kwezi mveliso, kunye nokuphucula ukuzinza kwazo ngokuhamba kwexesha. I-HEC ingasetyenziselwa ukuzinzisa i-emulsions, njenge-mayonnaise, ngokuthintela ukuhlukana kweoli kunye namanzi.

Kwishishini lokuthambisa, i-HEC isetyenziselwa uluhlu olubanzi lweemveliso zokhathalelo lomntu, kubandakanya i-shampoos, i-conditioner, i-lotions, kunye ne-creams. I-HEC inokuphucula ukuthungwa kunye nokuhambelana kwezi mveliso, ukuphucula iimpawu zabo zokuthambisa, kunye nokubonelela nge-smooth, velvety feel. Iyakwazi nokuzinzisa i-emulsions kwi-cosmetic formulations kunye nokunceda ukukhusela ukuhlukana kweoli kunye nezixhobo zamanzi.

Kwishishini lamachiza, i-HEC isetyenziswa njenge-binder kwi-tablet formulations ukuqinisekisa ukuba izithako zethebhulethi zihlala zixinzelelwe kunye. Ikwasetyenziswa njenge-thickener ye-topical formulations, apho inokuphucula i-viscosity kunye nokuzinza kwe-creams kunye namafutha. Ukongezelela, i-HEC isetyenziswe njenge-arhente yokukhutshwa okuqhubekayo kwiinkqubo zokuhanjiswa kweziyobisi, apho inokulawula izinga apho iziyobisi zikhutshwa emzimbeni.

I-HEC ineempawu ezininzi ezizodwa ezenza ukuba ibe yipolymer eluncedo kwiintlobo ezahlukeneyo zezicelo. Ezinye zezi propati ziquka:

Ukunyibilika kwamanzi: I-HEC i-soluble kakhulu yamanzi, eyenza kube lula ukuyifaka kwi-formula-based formulations.

I-Non-toxic kunye ne-biocompatible: I-HEC ngokuqhelekileyo ithathwa njengento ekhuselekileyo kunye ne-biocompatible, eyenza ibe luncedo kwizicelo zamachiza kunye ne-cosmetic.

I-Versatile: I-HEC i-polymer eguquguqukayo kakhulu enokuthi isetyenziswe kuluhlu olubanzi lwezicelo ngenxa yokukwazi ukwenza iigels kunye nokulungelelanisa kwiidigri ezahlukeneyo zokutshintshwa kunye nobunzima be-molecular.

Ukuqukumbela, i-hydroxyethyl cellulose i-polymer e-soluble yamanzi ephuma kwi-cellulose ngokongezwa kwamaqela e-hydroxyethyl.
