Nonionic soluble cellulose ether hydroxyethyl cellulose HEC

Hydroxyethylcellulose (HEC) ke nonionic soluble cellulose ether e sebelisoang haholo liindastering tse fapaneng. HEC e tsoa ho cellulose ea tlhaho mme e fetotsoe ho ba le lihlopha tsa hydroxyethyl mokokotlong oa cellulose. Phetoho ena e etsa hore HEC e qhibilihe haholo metsing le lihlapolli tse ling tsa polar, e leng se etsang hore e be polima e loketseng bakeng sa lisebelisoa tse fapaneng.

E 'ngoe ea litšebeliso tsa mantlha tsa HEC ke sekhomaretsi le sekhomaretsi lihlahisoa tse fapaneng tsa bareki le tsa indasteri. HEC e atisa ho sebelisoa ho litlolo le lihlahisoa tsa tlhokomelo ea botho tse kang li-shampoo, lotion le menoana ea meno ho fana ka viscosity le botsitso. E boetse e sebelisoa ka lipente, liaparo le li-adhesives ho fana ka thepa ea sekhomaretsi le ho ntlafatsa ho hanyetsa mongobo.

HEC e na le mekhoa e mengata ea ho haha ​​​​lihlahisoa tsena ka lebaka la bokhoni ba eona ba ho eketsa viscosity tsamaisong ea metsi ntle le ho ama haholo lihlahisoa tse ling tsa lihlahisoa. Ka ho kenyelletsa HEC ho lihlahisoa tsena, bahlahisi ba ka fetola botenya, sebopeho le ho tsitsa ha lihlahisoa tsa bona ho finyella litlhoko tsa bareki le litlhoko tsa indasteri.

Tšebeliso e 'ngoe ea bohlokoa ea HEC ke indastering ea meriana. HEC ke motsoako o tloaelehileng lihlahisoa tse ngata tsa meriana, ho kenyelletsa matlapa, li-capsules le mekhoa ea ho fana ka lithethefatsi. Ka lebaka la bokhoni ba bona ba ho fetola rheology le ho ruruha ha mefuta ea litekanyetso, HEC e ka ntlafatsa bioavailability ea metsoako e sebetsang le ho ntlafatsa taolo ea ho lokolloa ha lithethefatsi. HEC e boetse e sebelisetsoa ho ntlafatsa botsitso ba li-emulsions le ho emisoa ha lihlahisoa tsa meriana.

Lefapheng la lijo, HEC e sebelisoa e le motenya le ho tsitsisa lihlahisoa tse fapa-fapaneng tsa lijo, ho akarelletsa le li-sauces, liaparo le lihlahisoa tsa lebese. HEC ke motsoako o bolokehileng, oa tlhaho o lumelletsoeng ho sebelisoa lijong ke mekhatlo e laolang lefats'e ka bophara. E boetse e sebelisoa e le sebaka sa mafura lijong tse fokolang, ho fana ka sebopeho se tšoanang le molomo ho lihlahisoa tse tletseng mafura.

HEC e boetse e sebelisoa indastering ea kaho e le sekontiri le se tlamang lihlahisoa tsa samente tse kang li-grouts, mortars le li-adhesives. Thepa ea thixotropic ea HEC e etsa hore e be motsoako o loketseng bakeng sa lihlahisoa tsena, e leng ho li lumellang hore li lule li le teng le ho thibela ho sagging kapa ho rarolla. HEC e na le ho khomarela hantle le ho hanyetsa metsi, ho etsa hore e be motsoako oa bohlokoa oa ho thibela metsi le lihlahisoa tsa ho tiisa.

Hydroxyethyl cellulose ke ether e se nang ionic soluble cellulose e nang le mefuta e mengata ea lisebelisoa liindastering tse fapaneng. HEC ke karolo e feto-fetohang le ea bohlokoa lihlahisoa tse ngata tsa bareki le tsa indasteri, ho fana ka botsitso bo ntlafetseng, viscosity, le taolo ea ho lokolloa ha lithethefatsi. HEC ke motsoako oa tlhaho, o bolokehileng le tikoloho o amohetsoeng hore o sebelisoe ke linaha tse ngata ho pota lefatše. Thepa ea eona e ikhethang le ho feto-fetoha ha maemo ho etsa hore HEC e be motsoako oa bohlokoa lihlahisoa le liindasteri tse ngata.
