Ko ngā matū horoi ā-whakapūmau raupapa Betaine he matū horoi ā-whakapūmau kei roto ngā ngota N kaha. He tote tino kūpapa ēnei me te whānuitanga isoelectric whānui. E whakaatu ana i ngā āhuatanga dipole i roto i te whānuitanga whānui. He maha ngā taunakitanga e whakaatu ana kei roto ngā matū horoi betaine i te ahua o te tote ā-roto. Nō reira, i ētahi wā ka kiia ko te matū horoi tote ā-roto ammonium quaternary. E ai ki ngā kaikawe pokapū utu kino rerekē, ka taea te wehewehe i ngā matū horoi betaine i kōrerotia i roto i te rangahau o nāianei ki te carboxyl betaine, te sulfonic betaine, te phosphoric betaine, me ētahi atu.

He tote kūpapa ngā matū whakaora-ā-whakapūmau ā-whakapūmau raupapa Betaine, he whānui te whānuitanga o te isoelectric. E whakaatu ana i ngā āhuatanga dipole i roto i te whānuitanga pH whānui. Nā te noho o te hauota ammonium quaternary i roto i ngā ngota, he pai te pumau matū o te nuinga o ngā matū whakaora-ā-whakapūmau betaine i roto i ngā pāpāho waikawa me te kawakore. Mēnā kāore he rōpū mahi a te ngota pēnei i te here ether me te here ester, he pai te ātete ki te waikura.

He ngāwari te rewa o ngā matū whakaora amphoteric raupapa Betaine ki roto i te wai, i roto i ngā waikawa me ngā turanga kukū, tae atu ki roto i ngā otinga kukū o ngā tote kore-waro. Kāore e ngāwari te mahi tahi me ngā konganuku whenua kawakore me ētahi atu katote konganuku. He ngāwari te rewa o te betaine mekameka roa ki roto i te wai, ā, kāore e pāngia e te pH. Ko te wairewatanga o te betaine te mea nui e pāngia ana e te maha o ngā ngota waro. Ka taea e te kukū o te lauramide propyl betaine sx-lab30 i rewa ki roto i te wai te eke ki te 35%, engari he tino iti te wairewatanga o ngā homologues me ngā mekameka waro roa.

Ko te ātete wai mārō o ngā matū horoi ka kitea i roto i tō rātou manawanui ki ngā katote mārō konupūmā me te konupūmā me tō rātou kaha marara ki te hopi konupūmā. He maha ngā matū horoi amphoteric betaine e whakaatu ana i te tino pumau ki ngā katote konupūmā me te konupūmā. He pumau te pumau katote konupūmā o te nuinga o ngā matū horoi amphoteric sulfobetaine, engari he iti iho te uara pumau katote konupūmā o ngā matū amine tuarua e rite ana.

He nui te pahuka o ngā matū whakaora-ā-whakapūmau amphoteric raupapa Betaine. Whai muri i te whakakotahitanga me ngā matū whakaora-ā-whakapūmau anionic, ka kaha te taunekeneke a ngā ngota. Ka tino piki ake te pānga o te pahuka me te whakapūmau. Heoi anō, kāore ngā āhuatanga pahuka o ngā matū whakaora-ā-whakapūmau pīti e pāngia e te pakeketanga o te wai me te PH o te reo. Ka whakamahia hei matū whakaora-ā-whakapūmau, hei matū whakaora-ā-whakapūmau rānei, ā, ka taea te whakamahi i roto i te whānuitanga o te PH.
