Li-surfactant tsa amphoteric tsa letoto la Betaine ke li-surfactant tsa amphoteric tse nang le liathomo tse matla tsa alkaline N. Ke matsoai a sa nke lehlakore a 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-surfactant tsa betaine li teng ka mokhoa oa letsoai la kahare. Ka hona, ka linako tse ling e bitsoa quaternary ammonium internal salt surfactant. Ho ea ka bajari ba fapaneng ba setsi sa chaja se fosahetseng, li-surfactant tsa betaine tse tlalehiloeng lipatlisisong tsa hajoale li ka aroloa ka carboxyl betaine, sulfonic betaine, phosphoric betaine, jj.

Li-surfactant tsa amphoteric tsa letoto la Betaine ke matswai 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 naetrojene ea ammonium ea quaternary limolek'huleng, boholo ba li-surfactant tsa betaine li na le botsitso bo botle ba lik'hemik'hale mecheng ea asiti le ea alkaline. Ha feela molek'hule e se na lihlopha tse sebetsang tse kang tlamo ea ether le tlamo ea ester, ka kakaretso e na le khanyetso e ntle ea oxidation.

Li-surfactant tsa amphoteric tsa letoto la Betaine li bonolo ho qhibilihisa ka metsing, ka har'a li-acid tse kopaneng le metheo, esita le ka har'a litharollo tse kopaneng tsa letsoai le sa tloaelehang. Ha li bonolo ho sebetsa ka litšepe tsa lefats'e tsa alkaline le li-ion tse ling tsa tšepe. Betaine e telele ea ketane e bonolo ho qhibilihisa ka har'a metsi 'me ha e angoe ke pH. Ho qhibiliha ha betaine ho angoa haholo ke palo ea liathomo tsa khabone. Khokahano ea lauramide propyl betaine sx-lab30 e qhibilihisitsoeng ka har'a metsi e ka fihla ho 35%, empa ho qhibiliha ha li-homologue tse nang le liketane tse telele tsa khabone ho tlase haholo.

Ho hanyetsa metsi a thata ha li-surfactants ho bonahala ka ho mamella ha tsona li-ion tse thata tsa calcium le magnesium le matla a tsona a ho qhalanya sesepa sa calcium. Li-surfactants tse ngata tsa betaine amphoteric li bontša botsitso bo botle haholo ho li-ion tsa calcium le magnesium. Botsitso ba li-ion tsa calcium tsa li-surfactants tse ngata tsa sulfobetaine amphoteric bo tsitsitse, ha boleng ba botsitso ba li-ion tsa calcium tsa metsoako ea amine ea bobeli bo le tlase haholo.

Li-surfactant tsa amphoteric tsa letoto la Betaine li na le foam e ngata. Kamora ho kopanngoa le li-surfactant tsa anionic, limolek'hule li sebelisana ka matla. Tšusumetso ea ho foa le ho sebetsana e eketseha haholo. Ho feta moo, thepa ea foact ea li-surfactant tsa beet beet ha e angoe ke ho thatafala ha metsi le PH ea sebaka seo. Li sebelisoa e le li-agent tse foamisang kapa tse foamisang, 'me li ka sebelisoa mefuteng e mengata ea PH.
