Umahluko phakathi kwe-hydroxypropyl methylcelcelcelose ne hydroxyythy seluplose

Hydroxypropyl methylcelculose (hpmc)kwayeI-HYDROXYTYL ILANDILONE (Hec)zizinto ezimbini ezisetyenziswayo zeselfowuni. Zisetyenziswa ngokubanzi ekwakhiweni, amayeza, cosmetics, ukutya kunye namanye amashishini ngenxa yepropathi yakhe eyahlukileyo kunye nokusetyenziswa kwayo. Nangona zimbini izinto ezinyibilikayo zepolymer ezivela kwi-sellyulose yendalo, kukho umahluko ocacileyo phakathi kwezi zimbini kwisakhiwo sekhemikhali, intsebenzo kunye neMihlaba yesicelo.

I-1. Umahluko kwimo yemichiza

I-HPMC (Hydroxypropyl methylcelcelcelsulose)

Yisel-ionic ye-ionsulose i-ete ifunyenwe ngokuphendula ngokuphendula nge-sethanol kunye ne-methanol kunye ne-propylene oxide emva kokuqiniseka. Isakhiwo sayo semolekyuli siqulethe i-Manaxy (-och3) kunye ne-hydroxypropoxy (-C2chohch3) impahla. Inqanaba lokufakwa endaweni ye-HPMC lingalungiswa ngokwendlela eyahlukileyo.

Hec (hydroxyythl seluplose)

Yimveliso efunyanwa yi-Etheristic Reatition ye-SellUlose ne-Ebanone oxide emva kokuthathwa, kunye nesakhiwo sayo semolekyuli siqulathe i-hydroxyyl (-C2C2oh). I-Hec yi-ionic ye-ionic ye-ionic ye-iother, kwaye isidanga sayo sinokuhlengahlengiswa ngokweemfuno ezithile.

2. Umahluko weNtsebenzo

Ukunyibilikisa

I-kimbacell®hpmc inokukhawuleza inyibilikise amanzi abandayo ukwenza isisombululo esibonakalayo okanye se-visicy viscous, esichasayo kubushushu obuphezulu. Inetyiwa elungileyo kunye ne-alkali ukunganyangeki kwaye kunokubakho ngokukuko kuluhlu lwe-pH ebanzi (3-11).

I-kimbacell®fuc ikwanyibilikisa emanzini abandayo, kodwa izinga lokuchithwayo licotha, kwaye uzinzo kubushushu obuphezulu okanye imeko ephakamileyo ihlwempuzeke. Ukongeza, i-hec ayinantlonelo kwi-pH kwaye inokusetyenziswa kwi-PH Uluhlu lwe-2-12.

Isiphumo sokutyibilika

I-HPMC inefuthe eliqatha eliqatha kwaye inoluvo oluhle lwamanzi kunye nozinzo.

I-hec ikwanesiphumo esihle, kodwa ukubonwa kwayo kuchaphazeleka kakhulu ngumgangatho weShear kwaye ubonise iimpawu ezicekeceke.

Umsebenzi womphezulu

I-HPMC inomsebenzi othile womphezulu kwaye inokuvelisa i-olmation efanelekileyo kunye neziphumo zokwenza ifilimu.

I-HEC inomsebenzi womhlaba ophantsi kwaye ingenazo iipropathi zosulelo ezicacileyo, kodwa zineepropathi ezifanelekileyo zefilimu.

3. Umahluko wesicelo

Ifildi yokwakha

I-HPMC isetyenziswa ngokubanzi kwizinto zokwakha, ezinje nge-powty powder, i-tiles, i-tile., Ubutshinga, ubutshe, njl njl.

I-HEC iqhele ukusetyenziswa kwipeyinti ye-Latex kunye nepeyinti esekwe emanzini njenge-thickener kunye nokuzinzisa ukonyusa i-viscofity kunye neepropathi ezichasene nepeyinti.

Intsimi yamayeza

I-HPMC isetyenziswa ikakhulu njengezinto zokuhamba, iarhente yokukhutshwa kwearhente kunye ne-capsule ye-capsule yeetafile kwintsimi yamayeza.

I-hec ayifane isetyenziswe kwintsimi yamayeza kwaye ngamanye amaxesha njenge-thi checkener yokumiswa ngamachiza.

Imveliso ye-cosmetics kunye neemveliso zemichiza zemichiza

I-HPMC isetyenziswa kwiimveliso zonyango kunye nezicoci ukunika iimveliso ezingcono zokunyibilikisa kunye nokuzinza.

I-HEC isetyenziswa ngokubanzi eshampoo, ijeli yeshawari, njl njl.

Intsimi yokutya

I-HPMC isetyenziswa njenge-gickener, i-emulsifier kunye ne-stiblimizer ekutyeni kwaye isetyenziswa ngokubanzi eJelly, kwiiSaus kunye nempahla ebhakiweyo.

I-hec ayifane isetyenziswe kumzi-mveliso wokutya, kodwa inokusetyenziswa njenge-thi cokener kwezinye iziselo kunye neendlela.

I-4. Ixabiso kunye nentengiso

I-HPMC ihlala ibiza kakhulu kune-hec ngenxa yenkqubo yayo enzima kunye noluhlu olubanzi lokusetyenziswa. Inkqubo yemveliso yehek ilula kwaye isetyenziselwa ukuqina kunye nokuzinza, ukuze ixabiso liphantsi.

I-Hydroxypropyl Methylcelceltulose (HPMC) kunye ne-HydroxyEtheetethl seluplose (hec) I-kimbacell®hpmc ilungele ngakumbi kwiimfuno zendlela yokusebenza, inendawo yokugcina amanzi, kwaye ibonisa iipropathi zefilimu, kwaye inoluhlu olubanzi lwezicelo. I-hec, kwelinye icala, ihlala isetyenziswa kwi-cayishini, iikhemikhali zemihla ngemihla kunye namanye amathuba afuna ukuqina kunye nokumiswa ngenxa yeendleko zayo eziphantsi kunye nefuthe elihle. Ekukhetho, kuya kuthathelwa ingqalelo kwiimfuno ezithile zomsebenzi kunye neendleko zoqoqosho.
