Lintho tsa hydroxyethyl cellulose
Hydroxyethyl Cellulose (HEC) e na le thepa e 'maloa e e etsang hore e be polymer e feto-fetohang le ea bohlokoa lits'ebetsong tse fapaneng. Mona ke lintlha tse ling tsa bohlokoa tsa Hydroxyethyl Cellulose:
- Sollubility:
- HEC e qhibiliha haholo metsing, e etsa litharollo tse hlakileng le tse hlakileng. The solubility e lumella ho kenyelletsoa habonolo mefuteng e thehiloeng metsing, ho etsa hore e sebelisoe haholo liindastering tse kang litlolo, tlhokomelo ea botho le meriana.
- Viscosity:
- HEC e bonts'a thepa e teteaneng, e susumetsang viscosity ea tharollo. The viscosity e ka fetoloa ho latela lintlha tse kang tekanyo ea ho fetola, boima ba limolek'hule le mahloriso a HEC. Thepa ena e bohlokoa lits'ebetsong tseo ho tsona ho hlokahalang hore ho be le botsitso kapa sebopeho se lakatsehang, joalo ka litlolo, li-shampoo le lipente.
- Ho Etsa Lifilimi:
- HEC e na le thepa ea ho etsa lifilimi, e lumellang hore e thehe filimi e tšesaane, e tenyetsehang ha e sebelisoa holim'a libaka. Thepa ena e na le molemo lits'ebetsong tse ling tsa litlolo le tsa tlhokomelo ea motho, hammoho le lirapeng le likhomaretsi.
- Mofetoleli oa Rheology:
- HEC e sebetsa e le rheology modifier, e susumetsang phallo le boitšoaro ba libopeho. E thusa ho laola viscosity le ho ntlafatsa ts'ebetso ea kakaretso ea lihlahisoa tse kang lipente, lirafshoa le likhomaretsi.
- Paballo ea Metsi:
- Lisebelisoa tsa kaho, tse kang seretse le li-grouts, HEC e ntlafatsa ho boloka metsi. Thepa ena e thibela ho omisa ka potlako le ho ntlafatsa ts'ebetso ea lisebelisoa tsena.
- Moemeli oa ho tsitsisa:
- HEC e sebetsa e le moemeli oa botsitso ka li-emulsions le li-suspensions, ho thibela ho arohana ha mekhahlelo e fapaneng. Botsitso bona bo bohlokoa ho litlolo tse kang litlolo le lotion.
- Thermal Stability:
- HEC e bonts'a botsitso bo botle ba mocheso tlas'a maemo a tloaelehileng a ho sebetsa. Botsitso bona bo e lumella ho boloka thepa ea eona nakong ea mekhoa e fapaneng ea tlhahiso.
- Biocompatibility:
- HEC ka kakaretso e nkuoa e le biocompatible ebile e bolokehile hore e ka sebelisoa lits'ebetsong tsa litlolo le tsa meriana. E mamelloa hantle ke letlalo, 'me metsoako e nang le HEC hangata e bonolo.
- pH botsitso:
- HEC e tsitsitse ho feta mefuta e mengata ea pH, e etsa hore e tšoanelehe bakeng sa ho etsoa ka mefuta e fapaneng ea acidity kapa alkalinity.
- Tšebelisano:
- HEC e lumellana le mefuta e meng e mengata e sebelisoang ha ho etsoa lihlahisoa, e etsa hore e be polymer e fapaneng bakeng sa ho kopanya le likarolo tse fapaneng.
Motsoako oa thepa ena o etsa hore Hydroxyethyl Cellulose e be khetho e ratoang lits'ebetsong ho tloha ho lihlahisoa tsa tlhokomelo ea motho le meriana ho ea ho thepa ea kaho le lihlahisoa tsa indasteri. Sehlopha se ikhethileng le thepa ea HEC e ka fapana ho latela lintlha tse kang tekanyo ea ho fetola, boima ba limolek'hule le mekhoa ea tlhahiso.
