Betaine series amphoteric surfactants ke li-amphoteric surfactants tse nang le liathomo tse matla tsa alkaline N. Ha e le hantle ke letsoai le sa nke lehlakore le nang le mefuta e mengata ea isoelectric. Li bontša litšobotsi tsa dipole ka mefuta e mengata. Ho na le bopaki bo bongata ba hore li-betaine surfactants li teng ka mokhoa oa letsoai le ka hare. Ka hona, ka linako tse ling e bitsoa quaternary ammonium internal salt surfactant. Ho latela li-carriers tse fapaneng tse mpe tsa lits'ebeletso, li-surfactants tsa betaine tse tlalehiloeng lipatlisisong tsa hajoale li ka aroloa ka carboxyl betaine, sulfonic betaine, phosphoric betaine, jj.

Betaine series amphoteric surfactants ke matsoai a sa nke lehlakore a nang le mefuta e mengata ea isoelectric. Li bontša litšobotsi tsa dipole ka mefuta e mengata ea pH. Ka lebaka la boteng ba quaternary ammonium nitrogen limolek'huleng, boholo ba li-betaine surfactants li na le botsitso bo botle ba lik'hemik'hale mecheng ea asiti le alkaline. Hafeela molek'hule e se na lihlopha tse sebetsang tse kang ether bond le ester bond, ka kakaretso e na le khanyetso e ntle ea oxidation.

Betaine letoto la li-amphoteric surfactants li bonolo ho qhibiliha ka metsing, ka li-acid tse ngata le metheo, esita le ka litharollo tse tebileng tsa matsoai a sa tloaelehang. Ha ho bonolo ho sebetsa ka litšepe tsa lefatše tsa alkaline le li-ion tse ling tsa tšepe. Long chain betaine e bonolo ho qhibiliha sebakeng se nang le metsi 'me ha e amehe ke pH. The solubility ea betaine e angoa haholo ke palo ea liathomo tsa carbon. Motsoako oa lauramide propyl betaine sx-lab30 o qhibilihisitsoeng ka har'a metsi a nang le metsi a ka fihla ho 35%, empa ho qhibiliha ha li-homologue tse nang le liketane tse telele tsa carbon ho tlase haholo.

Ho hanyetsa metsi ka thata ha li-surfactants ho bonahala ka mamello ea tsona ho calcium le magnesium hard ions le matla a tsona a ho hasanya ho sesepa sa calcium. Li-surfactants tse ngata tsa betaine amphoteric li bontša botsitso bo botle haholo ho calcium le magnesium ions. Calcium ion stability ya boholo ba sulfobetaine amphoteric surfactants e tsitsitse, athe boleng ba botsitso ba ione ya calcium ya metsoako e tsamaellanang ya amine e tlase haholo.

Li-betaine series amphoteric surfactants li na le foam e ngata. Ka mor'a ho kopana le li-surfactants tsa anionic, limolek'hule li sebelisana ka matla. Phello ea ho foaming le ho sebetsana le eona e eketsehile haholo. Ho feta moo, thepa ea foam ea li-beet beet surfactants ha e amehe ke ho thatafala ha metsi le PH ea mahareng. Li sebelisoa e le li-foam kapa li-foam, 'me li ka sebelisoa mefuteng e mengata ea PH.
