ʻO ke au e ulu mau nei o nā surfactants honua e hāʻawi i kahi ʻano kūwaho maikaʻi no ka hoʻomohala ʻana a me ka hoʻonui ʻana o ka ʻoihana hoʻonaninani, kahi e kau ai i nā koi kiʻekiʻe aʻe ma ke ʻano o ka huahana, nā ʻano like ʻole, ka hana, a me ka ʻenehana. No laila, he mea nui e hoʻomohala pono i nā surfactants palekana, palupalu, maʻalahi ke palaho, a hāʻawi ʻia i nā hana kūikawā, no laila e kau ana i kahi kahua kumumanaʻo no ka hana ʻana a me ka hoʻohana ʻana i nā huahana hou. Pono e hāʻawi ʻia ka mea nui i ka hoʻomohala ʻana i nā surfactants glycoside-based, a me ka hoʻololi ʻana i nā polyol a me nā surfactants ʻano waiʻona; ke hana ʻana i ka noiʻi ʻōnaehana i nā surfactants i loaʻa mai ka soybean phospholipid; ka hana ʻana i nā ʻano o nā moʻo sucrose fatty acid ester; ka hoʻoikaika ʻana i nā haʻawina e pili ana i nā ʻenehana hui; a me ka hoʻonui ʻana i ka laulā o nā noi no nā huahana e kū nei.
ʻO ke ʻano o ka hoʻohuihui like ʻana o nā mea wai-hoʻoheheʻe ʻole i loko o ka wai e hana i kahi emulsion ua kapa ʻia ʻo emulsification. I nā mea hoʻonani, hoʻohana nui ʻia nā emulsifiers i ka hana ʻana i nā kirīmi a me nā lotions. ʻO nā ʻano maʻamau e like me ka pauka pauka a me ka "Zhongxing" vanishing cream he mau emulsions O/W (ʻaila-i-ka-wai), hiki ke hoʻohuihui ʻia me ka hoʻohana ʻana i nā emulsifiers anionic e like me nā kopa momona momona. ʻO ka emulsification me ke kopa e maʻalahi ai ka loaʻa ʻana o nā emulsions me ka haʻahaʻa o ka ʻaila, a ʻo ka hopena gelling o ke kopa e hāʻawi iā lākou me ka viscosity kiʻekiʻe. No nā kirīmi anuanu e loaʻa ana ka hapa nui o ka pae ʻaila, ʻo ka hapa nui o nā emulsions he ʻano W/O (wai-i-ka-ʻaila), kahi hiki ke koho ʻia ai ka lanolin kūlohelohe—me kona hiki ke omo wai ikaika a me ka viscosity kiʻekiʻe—ma ke ʻano he emulsifier. I kēia manawa, ʻo nā emulsifiers nonionic ka mea i hoʻohana nui ʻia, ma muli o ko lākou palekana a me ka haʻahaʻa o ka hoʻonāukiuki.
ʻO ke ʻano e hoʻonui ʻia ai ka solubility o nā mea hiki ke hoʻoheheʻe iki ʻia a i ʻole nā mea hiki ʻole ke hoʻoheheʻe ʻia ua kapa ʻia ʻo solubilization. Ke hoʻohui ʻia nā surfactants i ka wai, hāʻule koke ka ʻili o ka wai i ka wā mua, a ma hope o ka hoʻomaka ʻana o nā hui o nā molekala surfactant i ʻike ʻia he micelles e hana. ʻO ka nui o ka surfactant kahi e hana ʻia ai ka hoʻokumu ʻana o nā micelle ua kapa ʻia ʻo ka critical micelle concentration (CMC). Ke hiki ka nui o ka surfactant i ka CMC, hiki i nā micelles ke hoʻopaʻa i ka aila a i ʻole nā mea paʻa ma nā wēlau hydrophobic o kā lākou mau molekala, no laila e hoʻonui ai i ka solubility o nā mea hiki ʻole ke hoʻoheheʻe ʻia a i ʻole nā mea hiki ʻole ke hoʻoheheʻe ʻia.
I loko o nā mea hoʻonani, hoʻohana nui ʻia nā mea hoʻoheheʻe i ka hana ʻana i nā toners, nā aila lauoho, a me nā mea hoʻomākaukau no ka ulu ʻana o ka lauoho a me ka hoʻomaʻamaʻa ʻana. No ka mea, ʻokoʻa nā mea hoʻonani aila—e like me nā mea ʻala, nā momona, a me nā huaora hiki ke hoʻoheheʻe ʻia i ka aila—i ke ʻano a me ka polarity, ʻokoʻa hoʻi ko lākou ʻano o ka hoʻoheheʻe ʻana; no laila, pono e koho ʻia nā surfactants kūpono e like me nā mea hoʻoheheʻe. No ka laʻana, ʻoiai ʻo nā toners e hoʻoheheʻe i nā mea ʻala, nā aila, a me nā lāʻau lapaʻau, hiki ke hoʻohana ʻia nā alkyl polyoxyethylene ethers no kēia kumu. ʻOiai he mana hoʻoheheʻe ikaika ko nā alkylphenol polyoxyethylene ethers (OP-type, TX-type), he mea hoʻonāukiuki lākou i nā maka a no laila e pale ʻia ai. Eia kekahi, hōʻike nā derivatives amphoteric i hoʻokumu ʻia ma ka ʻaila castor i ka solubility maikaʻi loa no nā aila ʻala a me nā aila mea kanu, a ʻaʻole hoʻonāukiuki i nā maka, kūpono lākou no ka hoʻomākaukau ʻana i nā shampoos akahai a me nā mea hoʻonani ʻē aʻe.
