Ma hope o ka ionized i loko o ka wai, loaʻa iā ia ka hana ma luna a me ka hoʻopiʻi maikaʻi ʻole i kapa ʻia he surfactant anionic.
ʻO nā surfactants Anionic nā huahana me ka mōʻaukala lōʻihi loa, ka mana nui loa a me nā ʻano like ʻole ma waena o nā surfactants.Hoʻokaʻawale ʻia nā mea surfactants anionic i ka sulfonate a me ka alkyl Sulfate e like me ke ʻano o kā lākou mau pūʻulu hydrophilic, ʻo ia nā ʻano nui o nā surfactants anionic.ʻO nā hana like ʻole o ka surfactant ka mea nui i ʻike ʻia i ka hoʻololi ʻana i nā waiwai o ka ʻili wai, ka wai-wai a me ka wai-paʻa paʻa, kahi o ka ʻili (palena) waiwai o ka wai ka mea nui.
