Hydroxyethyl cellulose vs xanthan gum

Hydroxyethyl cellulose (HEC) le xanthan gum ke mefuta e 'meli e fapaneng ea li-thickeners tse sebelisoang hangata liindastering tse fapaneng, ho kenyeletsoa liindasteri tsa lijo, tsa meriana le tsa litlolo. Li-thickeners tsena ka bobeli ke li-polymer tse qhibilihang ka metsing tse ka eketsang viscosity le botsitso ba tharollo. Leha ho le joalo, li fapane ho ea ka thepa ea tsona le mekhoa eo li sebelisoang ho eona. Sehloohong sena, re tla bapisa hydroxyethyl cellulose le xanthan gum, re buisane ka thepa ea bona, mesebetsi le mekhoa ea bona.

Hydroxyethyl Cellulose (HEC)

Hydroxyethyl cellulose ke nonionic cellulose ether e nkiloeng ho selulose ka ho eketsoa ha lihlopha tsa hydroxyethyl mokokotlong oa cellulose. HEC e atisa ho sebelisoa e le motenya, stabilizer, le emulsifier liindasteri tse fapa-fapaneng, ho kenyeletsa le indasteri ea lijo, ea meriana le ea litlolo.

HEC e na le melemo e mengata ho feta mefuta e meng ea li-thickeners. E na le viscosity e phahameng mme e ka etsa tharollo e hlakileng maemong a tlase. E boetse e qhibiliha haholo metsing 'me e lumellana le mefuta e mengata ea lisebelisoa tse ling. Ho feta moo, HEC e ka ntlafatsa botsitso ba li-emulsions le ho emisoa, ho etsa hore e be molemo mefuteng e sa tšoaneng ea lihlahisoa.

HEC e atisa ho sebelisoa indastering ea litlolo ho ntlafatsa sebopeho le ho tsitsisa ha lihlahisoa tsa tlhokomelo ea botho, tse kang li-shampoo, li-conditioner, lotions, le litlolo. E ka boela ea sebetsa e le moemeli ea emisang, emulsifier, le binder. HEC e na le thuso ka ho khetheha lihlahisoa tsa tlhokomelo ea moriri, kaha e ka fana ka mokhoa o boreleli le o monate o ntlafatsang ho ata ha sehlahisoa.

Xanthan Gum

Xanthan gum ke polysaccharide e hlahisoang ke ho belisoa ha baktheria ea Xanthomonas campestris. Hangata e sebelisoa e le setepi le se matlafatsang indastering ea lijo, ea meriana le ea litlolo. Xanthan gum ke polysaccharide e boima ba molek'hule e phahameng, e e fang thepa ea eona e teteaneng.

Xanthan gum e na le melemo e 'maloa e le motenya. E na le viscosity e phahameng mme e ka etsa li-gel maemong a tlase. E boetse e qhibiliha haholo metsing 'me e khona ho mamella mefuta e mengata ea mocheso le maemo a pH. Ho feta moo, xanthan gum e ka ntlafatsa botsitso ba li-emulsion le ho emisoa, ho etsa hore e be molemo mefuteng e sa tšoaneng ea lihlahisoa.

Xanthan gum e atisa ho sebelisoa indastering ea lijo e le setenya le se tsitsisa lihlahisoa tse fapaneng, ho kenyeletsoa liaparo tsa salate, li-sauces le lihlahisoa tsa ho baka. E boetse e sebelisoa indastering ea meriana e le moemeli ea emisang le indastering ea litlolo e le motenya le ho tsitsisa lihlahisoa tse fapaneng tsa tlhokomelo ea motho, joalo ka litlolo le litlolo.

Papiso

HEC le xanthan gum li fapane ka litsela tse 'maloa. Phapang e 'ngoe e kholo ke mohloli oa polymer. HEC e tsoa ho cellulose, polima ea tlhaho e fumanoang limela, ha xanthan gum e hlahisoa ke ho belisoa ha libaktheria. Phapang ena mohloling e ka ama thepa le ts'ebeliso ea li-thickeners tse peli.

Phapang e 'ngoe pakeng tsa HEC le xanthan gum ke ho qhibiliha ha tsona. HEC e qhibiliha haholo metsing 'me e ka etsa litharollo tse hlakileng libakeng tse tlaase. Xanthan gum le eona e qhibiliha haholo ka metsing, empa e ka etsa li-gel maemong a tlase. Phapang ena ea solubility e ka ama sebopeho le ho tsitsana ha metsoako e nang le li-thickeners tsena.

Viscosity ea HEC le xanthan gum le eona e fapane. HEC e na le viscosity e phahameng, e etsang hore e be molemo e le motenya mefuteng e sa tšoaneng ea metsoako. Xanthan gum e na le viscosity e tlase ho feta HEC, empa e ntse e ka etsa li-gel maemong a tlase.
