Hydroxyethylcellulose (HEC) ke polima e qhibilihang ka metsing e seng ionic e sebelisoang haholo lihlahisoa tsa tlhokomelo ea letlalo. Joaloka selulose e fetotsoeng, hydroxyethylcellulose e hlahisa lihlopha tsa ethoxy ka har'a ketane ea tlhaho ea cellulose ea molek'hule ho etsa hore e be le ho qhibiliha ho hotle le botsitso metsing. Mesebetsi ea eona e ka sehloohong ea tlhokomelo ea letlalo e kenyelletsa ho teteaneng, ho nosetsa, ho tsitsisa, le ho ntlafatsa ho ama sehlahisoa.
1. Thickener
E 'ngoe ea mesebetsi ea bohlokoa ka ho fetisisa ea hydroxyethylcellulose ke ho ba motenya. Ka lihlahisoa tsa tlhokomelo ea letlalo tse kang lotions, litlolo, lihloekisi le li-gel, karolo ea li-thickeners ke ho eketsa viscosity le ho tsitsa ha sehlahisoa, ho etsa hore ho be bonolo ho e sebelisa le ho boloka holim'a letlalo, kahoo ho ntlafatsa phihlelo ea tšebeliso ea sehlahisoa. Hydroxyethyl cellulose e ka theha tharollo ea junifomo ea colloidal ka ho monya metsi le ho ruruha, ka hona ho eketsa viscosity ea foromo, 'me phello ena e teteaneng ha e amehe ke li-electrolyte, kahoo e ka ba teng ka mokhoa o tsitsitseng ka mefuta e sa tšoaneng ea liforomo.
2. Phello ea mongobo
Ka tlhokomelo ea letlalo, ho nosetsa ke mosebetsi oa bohlokoa haholo, 'me hydroxyethyl cellulose e boetse e kenya letsoho tabeng ena. E ka monya le ho boloka palo e itseng ea metsi, e etsa mokoallo oa mongobo ho thibela tahlehelo e feteletseng ea mongobo o tsoang holim'a letlalo. Ha e sebelisoa hammoho le li-moisturizers tse ling, hydroxyethyl cellulose e ka thusa ho notlela mongobo, ho lelefatsa phello ea mongobo, le ho boloka letlalo le le bonolo le le boreleli ka mor'a tšebeliso.
3. Stabilizer
Hydroxyethyl cellulose e boetse e sebetsa joalo ka stabilizer ho thusa ho thibela stratification ea sehlahisoa kapa pula. Lihlahisoa tse ngata tse entsoeng ka emulsified, tse kang lotions kapa litlolo, botsitso pakeng tsa karolo ea metsi le karolo ea oli ke ea bohlokoa. Selulose ea Hydroxyethyl e ka ntlafatsa botsitso ba sistimi ea emulsified le ho lelefatsa bophelo ba sethala sa sehlahisoa ka ho eketsa viscosity ea sistimi le ho thibela sedimentation ea metsoako.
4. Ntlafatsa ho ama sehlahisoa
Lihlahisoa tsa tlhokomelo ea letlalo, ho ama ke karolo ea bohlokoa ea phihlelo ea bareki. Hydroxyethyl cellulose e ka etsa hore sehlahisoa sena se be bonolo ebile se boreleli ntle le ho siea maikutlo a ho khomarela kapa a mafura. Ka hona, hangata e sebelisoa lihlahisoa tse hlokang ho ts'oaroa ho khathollang le ho bobebe, joalo ka li-gel le litlolo tse khathollang. Ho phaella moo, ho halefa ho fokolang le ho lumellana hantle ha letlalo la hydroxyethyl cellulose ho etsa hore e loketse lihlahisoa tsa tlhokomelo ea letlalo.
5. Ntlafatsa ts'ebetso ea sehlahisoa
Ho phaella mesebetsing e ka holimo, hydroxyethyl cellulose e ka boela ea ntlafatsa ho tšoana ha kabo ea lisebelisoa tse sebetsang, ho etsa bonnete ba hore metsoako e sebetsang e ka aroloa ka mokhoa o ts'oanang holim'a letlalo, kahoo e ntlafatsa phello ea kakaretso ea sehlahisoa. Ka mohlala, ka liforomo tse nang le li-antioxidants, metsoako e thibelang likokoana-hloko kapa metsoako e tšoeu, tšebeliso ea hydroxyethyl cellulose e ka thusa metsoako ena hore e sebetse ka katleho.
6. Hypoallergenicity
Joalo ka thepa ea polymer e seng ea ionic, hydroxyethyl cellulose e na le allergenicity e tlase le ho halefa ho tlase ka lebaka la sebopeho sa eona sa lik'hemik'hale, kahoo e boetse e sebelisoa haholo lihlahisoa tsa tlhokomelo ea letlalo. Bakeng sa batho ba tloaetseng ho kula kapa ho senngoa ke lithibelo tsa letlalo, hydroxyethyl cellulose ke khetho e sireletsehileng le e sebetsang.
7. Biodegradability
Hydroxyethyl cellulose ke sehlahisoa se fetotsoeng se nkiloeng ho selulose ea tlhaho, ka hona se na le biodegradability e ntle le botsoalle ba tikoloho. Boemong ba tlhokomelo e ntseng e eketseha ea bareki ho ts'ireletso ea tikoloho le nts'etsopele e tsitsitseng, lihlahisoa tse sebelisang hydroxyethyl cellulose li na le kamohelo e phahameng ea 'maraka.
8. Ho lumellana ha foromo
Hydroxyethyl cellulose e na le tumellano e ntle ea foromo mme e ka phela hammoho le mefuta e fapaneng ea metsoako e sebetsang, li-surfactants, li-emulsifiers, joalo-joalo ntle le maikutlo a mabe. Sena se etsa hore e sebelisoe haholo lihlahisoa tse fapaneng tsa tlhokomelo ea letlalo. Hydroxyethylcellulose e ka bapala karolo e tsitsitseng lits'ebetsong tsa karolo ea metsi le ea oli.
Hydroxyethylcellulose e na le likarolo tse fapaneng lihlahisoa tsa tlhokomelo ea letlalo, ho tloha ho teteaneng le ho nosetsa ho isa ho tsitsipano le ho ntlafatsa ho ama. E akaretsa hoo e batlang e le mesebetsi eohle ea bohlokoa ha ho etsoa lihlahisoa tsa tlhokomelo ea letlalo. Ho fokola ha eona ho tlase le ho lumellana hantle ha letlalo ho etsa hore e be motsoako o loketseng bakeng sa lihlahisoa tse fapaneng tsa tlhokomelo ea letlalo. Botsoalle ba eona ba tikoloho le ho senyeha ha tlhaho ho khotsofatsa tlhoko ea 'maraka ea hona joale ea lihlahisoa tse baballang tikoloho le tse tšoarellang. Ka bokhutšoanyane, hydroxyethylcellulose ha e ntlafatse boleng ba lihlahisoa tsa tlhokomelo ea letlalo feela, empa hape e kopana le litebello tsa bareki bakeng sa katleho ea sehlahisoa le polokeho.
