Hydroxyethylcellulose vs carbomer

Hydroxyethylcellulose (HEC) le carbomer ke li-polymer tse peli tse sebelisoang hangata indastering ea tlhokomelo ea motho. Li na le likarolo tse fapaneng tsa lik'hemik'hale le thepa, tse etsang hore li tšoanelehe bakeng sa likopo tse fapaneng.

HEC ke polima ea tlhaho, e qhibilihang ka metsing e tsoang ho selulose. Hangata e sebelisoa e le setei, emulsifier, le stabilizer lihlahisoa tse fapaneng tsa tlhokomelo ea motho joalo ka li-shampoo, li-conditioner le lihlapa tsa 'mele. HEC e tsejoa ka ho lumellana ha eona ho phahameng le lisebelisoa tse ling le bokhoni ba eona ba ho fana ka mokhoa o boreleli le o monate ho lihlahisoa. E boetse e tsejoa ka ho hlaka ha eona hantle le chefo e tlaase.

Carbomer, ka lehlakoreng le leng, ke polymer ea maiketsetso, e phahameng ea boima ba limolek'hule e sebelisoang hangata joalo ka ntho e tenya lihlahisoa tse fapaneng tsa tlhokomelo ea motho joalo ka li-gel le litlolo. E sebetsa hantle haholo ha ho etsoa lihlahisoa tse teteaneng le tse tsitsitseng, 'me e ka fana ka tekanyo e phahameng ea ho hlaka le ho emisa sehlahisoa se felileng. Carbomer e boetse e tsejoa ka taolo ea eona e ntle ea viscosity le bokhoni ba ho ntlafatsa ho ata ha lihlahisoa.

Phapang e 'ngoe e kholo lipakeng tsa HEC le carbomer ke ho qhibiliha ha tsona ka metsing. HEC e qhibiliha haholo metsing, athe carbomer e hloka ho se nke lehlakore ka moemeli oa alkaline joalo ka triethanolamine kapa sodium hydroxide hore e be metsi ka botlalo le ho teteaneng. Ho feta moo, HEC e tsejoa ka kutloisiso ea eona e tlase ho pH le liphetoho tsa mocheso, athe carbomer e ka angoa ke liphetoho pH le mocheso.

Ka kakaretso, HEC le carbomer ke mefuta e 'meli e fapaneng ea li-polymer tse nang le thepa e ikhethang le lits'ebetso. HEC ke polima ea tlhaho, e qhibilihang ka metsing, e atisang ho sebelisoa e le motenya le emulsifier, athe carbomer ke polima ea maiketsetso, e phahameng ea limolek'hule e sebetsang hantle haholo ha ho etsoa motsoako le ho tsitsisa. Khetho ea polymer e itšetlehile ka litlhoko tse khethehileng le thepa ea sebopeho.
