Betaine series amphoteric surfactants ndi amphoteric surfactants okhala ndi ma atomu amphamvu amchere a N.Ndi mchere wosalowerera ndale wokhala ndi mitundu yambiri ya isoelectric.Iwo amasonyeza makhalidwe dipole osiyanasiyana.Pali maumboni ambiri osonyeza kuti ma betaine surfactants alipo mu mawonekedwe a mchere wamkati.Choncho, nthawi zina amatchedwa quaternary ammonium internal salt surfactant.Malinga ndi zonyamulira zapakati zolephereka, ma betaine surfactants omwe adanenedwa mu kafukufuku wapano atha kugawidwa mu carboxyl betaine, sulfonic betaine, phosphoric betaine, etc.

Betaine series amphoteric surfactants ndi mchere wosalowerera ndale wokhala ndi mitundu yosiyanasiyana ya isoelectric.Amawonetsa mawonekedwe a dipole mumitundu yambiri ya pH.Chifukwa cha kukhalapo kwa quaternary ammonium nitrogen mu mamolekyu, ma betaine surfactants ambiri amakhala ndi kukhazikika kwamankhwala muzofalitsa za acidic ndi zamchere.Malingana ngati molekyulu ilibe magulu ogwira ntchito monga ether bond ndi ester bond, imakhala ndi kukana kwa okosijeni wabwino.

Betaine mndandanda amphoteric surfactants n'zosavuta kupasuka m'madzi, mu moyikirapo zidulo ndi zapansi, ndipo ngakhale moyikirapo mayankho a mchere mchere.Sizosavuta kuchita ndi zitsulo zamchere zamchere ndi ayoni ena achitsulo.Long chain betaine ndiyosavuta kusungunuka m'madzi amadzimadzi ndipo samakhudzidwa ndi pH.Kusungunuka kwa betaine kumakhudzidwa makamaka ndi kuchuluka kwa maatomu a carbon.Kuchuluka kwa lauramide propyl betaine sx-lab30 kusungunuka m'madzi amadzimadzi kumatha kufika 35%, koma kusungunuka kwa ma homologue okhala ndi unyolo wautali wa kaboni ndikotsika kwambiri.

Kulimbana ndi madzi olimba a ma surfactants kumawonekera pakulolera kwawo ku calcium ndi ma magnesium hard ions ndi mphamvu yawo yobalalitsa ku sopo wa calcium.Ambiri a betaine amphoteric surfactants amasonyeza kukhazikika kwa calcium ndi magnesium ions.Kukhazikika kwa ayoni wa calcium m'magulu ambiri a sulfobetaine amphoteric surfactants ndi okhazikika, pamene ma ion calcium okhazikika amagulu achiwiri a amine omwe ali nawo ndi otsika kwambiri.

Betaine series amphoteric surfactants ali ndi thovu lochuluka.Pambuyo pophatikizana ndi anionic surfactants, mamolekyu amalumikizana mwamphamvu.Zotsatira za thovu ndi kuthana nazo zimawonjezeka kwambiri.Komanso, thovu katundu wa beet beet surfactants sakhudzidwa ndi kuuma kwa madzi ndi PH wa sing'anga.Amagwiritsidwa ntchito ngati thovu kapena thovu, ndipo amatha kugwiritsidwa ntchito mumitundu yambiri ya PH.
