Uyini umehluko phakathi kwe-carbomer ne-hydroxyethylcellulose?

I-Carbomer ne-hydroxyethylcellulose (HEC) zombili ziyizithako ezisetshenziswa kakhulu ezimbonini ezahlukahlukene, ikakhulukazi kwezimonyo, ezemithi, nemikhiqizo yokunakekela umuntu. Naphezu kokusetshenziswa kwazo okufanayo njengama-ejenti okuqina kanye neziqinisi, zinezakhi zamakhemikhali ezihlukile, izakhiwo, kanye nezicelo.

1. Ukwakheka Kwamakhemikhali:

I-Carbomer: Ama-Carbomers angama-polymers anesisindo samangqamuzana aphezulu e-acrylic axhumene ne-polyalkenyl ether noma i-divinyl glycol. Ngokuvamile zikhiqizwa ngokusabela kwe-polymerization.

I-Hydroxyethylcellulose: I-Hydroxyethylcellulose, ngakolunye uhlangothi, iphuma ku-cellulose, i-polymer eyenzeka ngokwemvelo. Ikhiqizwa ngokuphatha i-cellulose nge-sodium hydroxide ne-ethylene oxide ukwethula amaqembu e-hydroxyethyl kumgogodla we-cellulose.

2. Isakhiwo samangqamuzana:

I-Carbomer: Ama-Carbomer anesakhiwo samangqamuzana esinegatsha ngenxa yemvelo yawo exhumene. Lokhu kuhlanganisa kunomthelela ekhonweni labo lokwenza inethiwekhi enezinhlangothi ezintathu lapho ifakwe amanzi, okuholela ekuqinisweni okuphumelelayo kanye nezakhiwo ze-gelling.

I-Hydroxyethylcellulose: I-Hydroxyethylcellulose igcina umugqa wesakhiwo se-cellulose, namaqembu e-hydroxyethyl axhunywe kumayunithi e-glucose eduze kweketango le-polymer. Lesi sakhiwo somugqa sinomthelela ekuziphatheni kwaso njenge-thickener ne-stabilizer.

3. Ukunyibilika:

I-Carbomer: I-Carbomers ijwayele ukunikezwa ngendlela eyimpuphu futhi ayincibiliki emanzini. Kodwa-ke, angakhukhumala futhi akhiphe amanzi emanzini, enze amajeli asobala noma ama-viscous dispersions.

IHydroxyethylcellulose: IHydroxyethylcellulose nayo ihlinzekwa ngesimo esiyimpuphu kodwa incibilika kalula emanzini. Iyancibilika ukuze yenze izixazululo ezicacile noma ezixubene kancane, kuye ngokugxila kanye nezinye izingxenye zokwakheka.

4. Ukuqina kwezakhiwo:

I-Carbomer: I-Carbomers iwugqinsi olusebenza kahle kakhulu futhi ingakha i-viscosity ezinhlobonhlobo zokwakheka, okuhlanganisa okhilimu, amajeli, namaloshini. Banikeza izakhiwo ezinhle kakhulu zokumisa futhi zivame ukusetshenziselwa ukuzinzisa ama-emulsions.

I-Hydroxyethylcellulose: I-Hydroxyethylcellulose nayo isebenza njenge-thickener kodwa ibonisa ukuziphatha okuhlukile kwe-rheological uma kuqhathaniswa nama-carbomers. Inikeza ukugeleza kwe-pseudoplastic noma i-shear-thinning ekwakhiweni, okusho ukuthi i-viscosity yayo iyancipha ngaphansi kwengcindezi yokugunda, yenza kube lula ukusetshenziswa nokusabalalisa.

5. Ukuhambisana:

I-Carbomer: I-Carbomers iyahambisana nezinhlobonhlobo zezithako zezimonyo namazinga e-pH. Kodwa-ke, zingadinga ukungathathi hlangothi ngama-alkali (isb., i-triethanolamine) ukuze kuzuzwe ukujiya okuphezulu kanye nezakhiwo ze-gelling.

IHydroxyethylcellulose: IHydroxyethylcellulose iyahambisana nezinyibilikisi ezehlukene kanye nezithako ezijwayelekile zezimonyo. Iqinile phezu kobubanzi be-pH ebanzi futhi ayidingi ukungathathi hlangothi ukuze ishube.

6. Izindawo zokufaka isicelo:

I-Carbomer: Ama-Carbomer athola ukusetshenziswa okubanzi emikhiqizweni yokunakekelwa komuntu siqu efana nokhilimu, ama-lotion, amajeli, kanye nokwakheka kwezinwele. Ziphinde zisetshenziswe emikhiqizweni yezemithi efana namajeli asezindaweni ezishisayo nezisombululo zamehlo.

IHydroxyethylcellulose: I-Hydroxyethylcellulose ivamise ukusetshenziswa ekwenziweni kwezimonyo nokomuntu siqu, okuhlanganisa ama-shampoos, ama-conditioner, amawasha omzimba, kanye nomuthi wokuxubha amazinyo. Ibuye isetshenziswe emikhakheni yemithi, ikakhulukazi ekwakhiweni kwezihloko.

7. Izici zezinzwa:

I-Carbomer: Amajeli e-Carbomer ngokuvamile abonisa ukuthungwa okubushelelezi nokunamafutha, anikeza umuzwa ofiselekayo wezinzwa ekwakhiweni. Kodwa-ke, bangase bazizwe beqinile kancane noma benamathele ekusebenziseni kwezinye izimo.

I-Hydroxyethylcellulose: I-Hydroxyethylcellulose inika umuzwa osilika futhi onganamatheli ekwakhiweni. Ukuziphatha kwayo kokunciphisa i-shear kunomthelela ekusabalaleni kalula nokumuncwa, okuthuthukisa ulwazi lomsebenzisi.

8. Izimiso Zokucatshangelwa:

I-Carbomer: Ama-Carbomers ngokuvamile aqashelwa njengaphephile (i-GRAS) yiziphathimandla ezilawulayo uma esetshenziswa ngokuhambisana nemikhuba emihle yokukhiqiza (GMP). Kodwa-ke, izimfuneko ezithile zokulawula zingahluka kuye ngokusetshenziswa okuhlosiwe kanye nesifunda sendawo.

I-Hydroxyethylcellulose: I-Hydroxyethylcellulose nayo ibhekwa njengephephile ukuthi isetshenziswe ezimonyo nasezikhemisi, ngokugunyazwa okungokomthetho okuvela kuziphathimandla ezifanele. Ukuhambisana nemithethonqubo esebenzayo kanye nemihlahlandlela kubalulekile ekuqinisekiseni ukuphepha nokusebenza komkhiqizo.

kuyilapho kokubili i-carbomer kanye ne-hydroxyethylcellulose isebenza njengama-thickeners aphumelelayo kanye nezinzile ekubunjweni okuhlukahlukene, ihluke ngokuphathelene nokwakheka kwamakhemikhali, isakhiwo samangqamuzana, ukuncibilika, izakhiwo eziqina, ukuhambisana, izindawo zokufaka isicelo, izici zezinzwa, nokucatshangelwa kokulawula. Ukuqonda lo mehluko kubalulekile ukuze abaqulunqi bakhethe isithako esifaneleka kakhulu sezidingo zabo zomkhiqizo othile kanye nemibandela yokusebenza.
