Carbomer le hydroxyethylcellulose (HEC) ka bobeli ke metsoako e sebelisoang hangata liindastering tse fapaneng, haholo litlolong, meriana le lihlahisoa tsa tlhokomelo ea motho. Ho sa tsotellehe ts'ebeliso ea tsona e ts'oanang e le li-ajenti tse teteaneng le li-stabilizers, li na le likarolo tse ikhethang tsa lik'hemik'hale, thepa le lisebelisoa.
1. Sebopeho sa Lik'hemik'hale:
Carbomer: Li-Carbomers ke li-polymers tsa boima ba limolek'hule tse phahameng tsa acrylic acid tse hokahantsoeng le polyalkenyl ethers kapa divinyl glycol. Hangata li hlahisoa ka karabelo ea polymerization.
Hydroxyethylcellulose: Hydroxyethylcellulose, ka lehlakoreng le leng, e tsoa ho cellulose, polima ea tlhaho ea tlhaho. E hlahisoa ka ho phekola cellulose ka sodium hydroxide le ethylene oxide ho hlahisa lihlopha tsa hydroxyethyl mokokotlong oa cellulose.
2. Sebopeho sa Limolek'hule:
Carbomer: Li-Carbomer li na le sebopeho sa limolek'hule tse nang le makala ka lebaka la tlhaho ea tsona e hokahaneng. Lekala lena le kenya letsoho ho matla a bona a ho theha marang-rang a mararo ha a le metsi, e leng se lebisang ho matla a maholo le thepa ea gelling.
Hydroxyethylcellulose: Hydroxyethylcellulose e boloka sebopeho sa mohala oa selulose, ka lihlopha tsa hydroxyethyl tse hokelletsoeng ho liyuniti tsa tsoekere haufi le ketane ea polymer. Sebopeho sena sa linear se susumetsa boitšoaro ba sona e le setenya le se tsitsitseng.
3. Sollubility:
Carbomer: Li-Carbomer hangata li fanoa ka foromo ea phofo 'me ha li qhibilihe ka metsing. Leha ho le joalo, li ka ruruha 'me tsa hydrate ka litharollo tse nang le metsi, li etsa li-gel tse bonaletsang kapa li-viscous dispersions.
Hydroxyethylcellulose: Hydroxyethylcellulose le eona e fanoa e le phofo empa e bonolo ho qhibiliha metsing. E qhibiliha ho etsa litharollo tse hlakileng kapa tse fokolang hanyane, ho latela mohopolo le likarolo tse ling tsa sebopeho.
4. Thickening Properties:
Carbomer: Li-Carbomer li sebetsa hantle haholo 'me li ka etsa viscosity ka mefuta e mengata ea litlolo, ho kenyelletsa litlolo, lijeli le litlolo. Li fana ka thepa e babatsehang ea ho emisa 'me hangata li sebelisetsoa ho tsitsisa emulsions.
Hydroxyethylcellulose: Hydroxyethylcellulose e boetse e sebetsa joalo ka motenya empa e bontša boitšoaro bo fapaneng ba rheological ha bo bapisoa le li-carbomer. E fana ka phallo ea pseudoplastic kapa shear-thinning ho metsoako, ho bolelang hore viscosity ea eona e fokotseha tlas'a khatello ea ho kuta, e nolofalletsang ho sebelisoa habonolo le ho hasana.
5. Ho lumellana:
Carbomer: Li-Carbomer li tsamaisana le mefuta e mengata ea litlolo tsa litlolo le maemo a pH. Leha ho le joalo, li ka 'na tsa hloka ho se nke lehlakore ka alkalis (mohlala, triethanolamine) ho finyella thepa e lekaneng ea ho tenya le ea gelling.
Hydroxyethylcellulose: Hydroxyethylcellulose e tsamaellana le metsoako e mengata e fapaneng le metsoako e tloaelehileng ea litlolo. E tsitsitse ho feta pH e pharaletseng 'me ha e hloke ho se nke lehlakore bakeng sa ho teteaneng.
6. Libaka tsa Kopo:
Carbomer: Li-Carbomer li fumana ts'ebeliso e ngata lihlahisoa tsa tlhokomelo ea motho joalo ka litlolo, litlolo, li-gel le litlolo tsa tlhokomelo ea moriri. Li boetse li sebelisoa lihlahisoa tsa meriana tse kang li-gels tsa topical le litharollo tsa ophthalmic.
Hydroxyethylcellulose: Hydroxyethylcellulose hangata e sebelisoa litlolong tsa litlolo le tsa tlhokomelo ea motho ka mong, ho kenyeletsoa li-shampoo, li-conditioner, lihlapa tsa 'mele le sesepa sa meno. E boetse e sebelisoa lits'ebetsong tsa meriana, haholo-holo mefuteng ea lihlooho.
7. Litšobotsi tsa kutlo:
Carbomer: Li-gels tsa Carbomer hangata li bonts'a sebopeho se boreleli, se fanang ka boiphihlelo bo lakatsehang ba kutlo ho metsoako. Leha ho le joalo, ba ka 'na ba ikutloa ba le thata hanyenyane kapa ba khomarela ha ba sebelisoa maemong a mang.
Hydroxyethylcellulose: Hydroxyethylcellulose e fana ka maikutlo a silky le a sa khomarelang ho metsoako. Boitšoaro ba eona ba ho fokotsa sekiri bo thusa ho ata habonolo le ho monya, ho ntlafatsa boiphihlelo ba mosebelisi.
8. Mehopolo ea Taolo:
Carbomer: Li-Carbomer ka kakaretso li amoheloa e le tse bolokehileng (GRAS) ke balaoli ba taolo ha li sebelisoa ho latela mekhoa e metle ea tlhahiso (GMP). Leha ho le joalo, litlhoko tse ikhethileng tsa taolo li ka fapana ho latela ts'ebeliso e reriloeng le sebaka sa tikoloho.
Hydroxyethylcellulose: Hydroxyethylcellulose e boetse e nkoa e sireletsehile bakeng sa tšebeliso ea litlolo le meriana, ka tumello ea taolo e tsoang ho balaoli ba amehang. Ho latela melao le litataiso tse sebetsang ho bohlokoa bakeng sa ho netefatsa polokeho le katleho ea sehlahisoa.
ha bobeli ba carbomer le hydroxyethylcellulose ba sebetsa e le li-thickeners tse sebetsang hantle le li-stabilizers ka mekhoa e sa tšoaneng, li fapane ho ea ka sebopeho sa lik'hemik'hale, sebopeho sa limolek'hule, solubility, thepa e teteaneng, ho lumellana, libaka tsa kopo, litšoaneleho tsa kutlo, le lintlha tsa taolo. Ho utloisisa liphapang tsena ke habohlokoa hore baetsi ba lihlahisoa ba khethe motsoako o loketseng litlhoko tsa bona tse khethehileng tsa sehlahisoa le mekhoa ea ho sebetsa.
