I-Betaine series amphoteric surfactants zi-amphoteric surfactants eziqulethe iiathom ze-alkaline ezomeleleyo ze-N. Ziityuwa ezingathathi hlangothi ngokwenene ezinoluhlu olubanzi lwe-isoelectric. Babonisa iimpawu ze-dipole kuluhlu olubanzi. Kukho ubungqina obuninzi bokuba i-betaine surfactants ikhona ngendlela yetyuwa yangaphakathi. Ke ngoko, ngamanye amaxesha ibizwa ngokuba yi-quaternary ammonium yangaphakathi yetyuwa ye-surfactant. Ngokwahlukileyo abathwali beziko lentlawulo engalunganga, i-betaine surfactants echazwe kuphando lwangoku inokohlulwa ibe yi-carboxyl betaine, i-sulfonic betaine, i-phosphoric betaine, njl.

Betaine series amphoteric surfactants ziityuwa ezingathathi hlangothi ezinoluhlu olubanzi lwe-isoelectric. Babonisa iimpawu ze-dipole kuluhlu olubanzi lwe-pH. Ngenxa yobukho be-quaternary ammonium nitrogen kwiimolekyuli, uninzi lwe-betaine surfactants lunozinzo olululo lweekhemikhali kwimithombo ye-acidic kunye ne-alkaline. Ngethuba nje i-molecule ingenayo amaqela asebenzayo afana ne-ether bond kunye ne-ester bond, ngokuqhelekileyo inokumelana ne-oxidation efanelekileyo.

Betaine series amphoteric surfactants kulula ukunyibilika emanzini, kwi-acids concentrated kunye neziseko, nakwizisombululo ezigxininisiweyo zeetyuwa ezingaphiliyo. Akulula ukuba zisebenze ngeentsimbi zomhlaba zealkaline kunye nezinye ii-ion zetsimbi. I-betaine yetsheyini ende kulula ukuyinyibilika kwindawo enamanzi kwaye ayichatshazelwa yi-pH. Ukunyibilika kwebetaine kuchaphazeleka ikakhulu linani leathom zekhabhoni. I-concentration ye-lauramide propyl betaine sx-lab30 inyibilikiswe kwindawo enamanzi inokufikelela kwi-35%, kodwa ukunyibilika kwee-homologues kunye ne-carbon chain chain iphantsi kakhulu.

Ukuxhathisa kwamanzi anzima kwi-surfactants kubonakala ekunyamezeleni kwabo i-calcium kunye ne-magnesium ion enzima kunye namandla abo okusabalalisa kwisepha ye-calcium. Uninzi lwe-betaine amphoteric surfactants lubonisa uzinzo oluhle kakhulu kwi-calcium kunye ne-magnesium ion. Uzinzo lwe-calcium ion uninzi lwe-sulfobetaine amphoteric surfactants luzinzile, ngelixa ixabiso lokuzinza kwe-calcium ion kwiikhompawundi ze-amine yesibini ezihambelanayo lisezantsi kakhulu.

Betaine series amphoteric surfactants zizityebi kugwebu. Emva kokudibanisa kunye ne-anionic surfactants, iimolekyuli zisebenzisana kakhulu. Umphumo we-foaming kunye nokujongana nokwandisa kakhulu. Ngaphezu koko, iimpawu ze-foam ze-beet beet surfactants azichatshazelwa bubulukhuni bamanzi kunye ne-PH ye-medium. Zisetyenziswa njengeejenti zogwebu okanye amagwebu, kwaye zingasetyenziswa kuluhlu olubanzi lwePH.
