I-Hydroxyethyl cellulose vs xanthan gum

I-Hydroxyethyl cellulose (HEC) kunye ne-xanthan gum ziintlobo ezimbini ezahlukeneyo ze-thickeners ezisetyenziswa ngokuqhelekileyo kumashishini ahlukeneyo, kuquka ukutya, amayeza, kunye nemizi mveliso yokuthambisa. Zombini ezi zingqimba zi-polymers ezinyibilikayo zamanzi ezinokunyusa i-viscosity kunye nokuzinza kwezisombululo. Nangona kunjalo, ziyahluka ngokweempawu zazo kunye nezicelo ezisetyenziswa kuzo. Kule nqaku, siya kuthelekisa i-hydroxyethyl cellulose kunye ne-xanthan gum, sixoxa ngeempawu zabo, imisebenzi, kunye nokusetyenziswa.

Iselulosi yeHydroxyethyl (HEC)

I-Hydroxyethyl cellulose yi-nonionic cellulose ether ephuma kwi-cellulose ngokongezwa kwamaqela e-hydroxyethyl kwi-cellulose backbone. I-HEC iqhele ukusetyenziswa njenge-thickener, i-stabilizer, kunye ne-emulsifier kumashishini ahlukeneyo, kuquka ukutya, amayeza, kunye namashishini okuthambisa.

I-HEC ineengenelo ezininzi ngaphezu kwezinye iintlobo ze-thickeners. Ine-viscosity ephezulu kwaye inokwenza izisombululo ezicacileyo kwiindawo eziphantsi. Ikwanyibilika kakhulu emanzini kwaye iyahambelana noluhlu olubanzi lwezinye izithako. Ngaphezu koko, i-HEC inokuphucula ukuzinza kwe-emulsions kunye nokumiswa, okwenza kube luncedo kwiintlobo ezahlukeneyo zokuqulunqa.

I-HEC isetyenziswa ngokuqhelekileyo kwishishini lezinto zokuthambisa ukuze kuphuculwe ukuthungwa kunye nokuhambelana kweemveliso zokunyamekela komntu, ezifana ne-shampoos, i-conditioners, i-lotions, kunye ne-creams. Isenokuthi isebenze njenge-arhente exhomayo, i-emulsifier, kunye ne-binder. I-HEC iluncedo ngokukhethekileyo kwiimveliso zokunakekelwa kweenwele, njengoko inokubonelela ngokucokisekileyo kunye ne-creamy texture eyenza ukusasazeka kwemveliso.

Xanthan Gum

I-Xanthan gum yipolysaccharide eveliswa kukubiliswa kwe-Xanthomonas campestris bacteria. Isetyenziswa ngokuqhelekileyo njenge-thickener kunye ne-stabilizer kumashishini okutya, amayeza, kunye ne-cosmetic. I-Xanthan gum yi-polysaccharide ephezulu ye-molecular weight, enika iimpawu zayo zokujiya.

I-Xanthan gum ineenzuzo ezininzi njenge-thickener. Ine-viscosity ephezulu kwaye inokwenza iigels kwiindawo eziphantsi. Ikwanokunyibilika kakhulu emanzini kwaye inokumelana noluhlu olubanzi lobushushu kunye namanqanaba e-pH. Ngaphezu koko, i-xanthan gum inokuphucula ukuzinza kwe-emulsions kunye nokumiswa, okwenza kube luncedo kwiintlobo ezahlukeneyo zokuqulunqa.

I-Xanthan gum idla ngokusetyenziswa kwishishini lokutya njengento etyebisayo kunye nokuzinzisa kwiimveliso ezahlukeneyo, kubandakanya ukunxitywa kwesaladi, iisosi, kunye neemveliso zokubhaka. Ikwasetyenziswa kwishishini lamachiza njengearhente yokumisa kunye nakwishishini lokuthambisa njenge-thickener kunye ne-stabilizer kwiimveliso ezahlukeneyo zokhathalelo lomntu, ezifana ne-lotions kunye ne-creams.

Ukuthelekisa

I-HEC kunye ne-xanthan gum zihluke ngeendlela ezininzi. Omnye umahluko omkhulu ngumthombo wepolymer. I-HEC ivela kwi-cellulose, i-polymer yendalo efumaneka kwizityalo, ngelixa i-xanthan gum iveliswa ngokuvutshelwa kweebhaktheriya. Lo mahluko kumthombo unokuchaphazela iipropati kunye nokusetyenziswa kwe-thickeners ezimbini.

Omnye umahluko phakathi kwe-HEC kunye ne-xanthan gum kukunyibilika kwazo. I-HEC inyibilika kakhulu emanzini kwaye inokwenza izisombululo ezicacileyo kwiindawo eziphantsi. I-Xanthan gum ikwanyibilika kakhulu emanzini, kodwa inokwenza iijeli kwindawo ephantsi. Lo mahluko kwi-solubility unokuchaphazela ukuthungwa kunye nokuhambelana kwezinto eziqulethwe ezi zingqimba.

I-viscosity ye-HEC kunye ne-xanthan gum nayo iyahluka. I-HEC ine-viscosity ephezulu, eyenza ibe luncedo njenge-thickener kwiintlobo ezahlukeneyo zokuqulunqa. I-Xanthan gum ine-viscosity ephantsi kune-HEC, kodwa isenokwenza iigels kwiindawo eziphantsi.
