Ii-surfactants ze-amphoteric ze-Betaine series zii-surfactants ze-amphoteric eziqulathe ii-atom ze-alkaline N ezinamandla. Ziityuwa ezingathathi cala ngokwenene ezinoluhlu olubanzi lwe-isoelectric. Zibonisa iimpawu ze-dipole kuluhlu olubanzi. Kukho ubungqina obuninzi bokuba ii-surfactants ze-betaine zikhona ngohlobo lwetyuwa yangaphakathi. Ke ngoko, ngamanye amaxesha zibizwa ngokuba yi-quaternary ammonium internal salt surfactant. Ngokweenkampani ezahlukeneyo ze-negative charge center, ii-surfactants ze-betaine ezichazwe kuphando lwangoku zinokwahlulwa zibe yi-carboxyl betaine, i-sulfonic betaine, i-phosphoric betaine, njl.

Ii-surfactants ze-amphoteric ze-Betaine series ziityuwa ezingathathi hlangothi ezinoluhlu olubanzi lwe-isoelectric. Zibonisa iimpawu ze-dipole kuluhlu olubanzi lwe-pH. Ngenxa yokubakho kwe-quaternary ammonium nitrogen kwiimolekyuli, uninzi lwee-surfactants ze-betaine zinozinzo oluhle lweekhemikhali kwi-acidic kunye ne-alkaline media. Logama nje imolekyuli ingenamaqela asebenzayo afana ne-ether bond kunye ne-ester bond, ngokubanzi inokumelana okuhle kwe-oxidation.

Ii-surfactants ze-amphoteric ze-Betaine series kulula ukuzinyibilikisa emanzini, kwii-asidi ezixineneyo kunye neziseko, kwanakwizisombululo ezixineneyo zeetyuwa ezingaphiliyo. Akulula ukuzisebenzisa ngeentsimbi zomhlaba ze-alkaline kunye nezinye ii-ion zesinyithi. I-betaine yetyathanga elide kulula ukuyinyibilikisa kwindawo enamanzi kwaye ayichaphazeleki yi-pH. Ukunyibilika kwe-betaine kuchaphazeleka kakhulu linani lee-athomu zekhabhoni. Uxinzelelo lwe-lauramide propyl betaine sx-lab30 olunyibilikisiweyo kwindawo enamanzi lunokufikelela kwi-35%, kodwa ukunyibilika kwee-homologues ezineetyathanga zekhabhoni ezinde kuphantsi kakhulu.

Ukumelana namanzi okuqinileyo kwee-surfactants kubonakala ngokunyamezela kwazo ii-ions eziqinileyo ze-calcium kunye ne-magnesium kunye namandla azo okusasazeka kwisepha ye-calcium. Ii-surfactants ezininzi ze-betaine amphoteric zibonisa uzinzo oluhle kakhulu kwii-ions ze-calcium kunye ne-magnesium. Uzinzo lwee-ion ze-calcium ezininzi ze-sulfobetaine amphoteric surfactants luzinzile, ngelixa ixabiso lozinzo lwee-ion ze-calcium ze-compounds ze-amine yesibini ezifanelekileyo liphantsi kakhulu.

Ii-surfactants ze-amphoteric ze-Betaine series zityebile kwi-foam. Emva kokudityaniswa nee-surfactants ze-anionic, iimolekyuli ziyasebenzisana kakhulu. Isiphumo sokugqwala kunye nokulwa siyanda kakhulu. Ngaphezu koko, iipropati ze-foam zee-surfactants ze-beet beet azichaphazeleki bubunzima bamanzi kunye ne-PH yesixhobo. Zisetyenziswa njengee-agents zokugqwala okanye ii-foam, kwaye zingasetyenziswa kuluhlu olubanzi lwe-PH.
