Isbeddelka caalamiga ah ee sii kordhaya ee surfactants wuxuu bixiyaa jawi dibadeed oo wanaagsan oo loogu talagalay horumarinta iyo ballaarinta warshadaha qurxinta, taas oo iyaduna keenta baahiyo sii kordheysa oo ku saabsan qaab-dhismeedka badeecadaha, kala duwanaanshaha, waxqabadka, iyo tiknoolajiyada. Sidaa darteed, waa lama huraan in si nidaamsan loo horumariyo surfactants-ka kuwaas oo ammaan ah, khafiif ah, si fudud u burburi kara, oo leh shaqooyin gaar ah, taasoo saldhig u ah abuurista iyo hirgelinta alaabada cusub. Mudnaanta waa in la siiyaa horumarinta surfactants-ka ku salaysan glycoside, iyo sidoo kale kala duwanaanshaha surfactants-ka polyol iyo nooca khamriga; sameynta cilmi-baaris nidaamsan oo ku saabsan surfactants-ka laga soo qaatay soybean phospholipid; soo saarista noocyo kala duwan oo taxane ah oo ah ester-ka dufanka leh ee sucrose; xoojinta daraasadaha ku saabsan isku-darka tiknoolajiyada; iyo ballaarinta baaxadda codsiyada alaabada jira.
Ifafaalaha ay walxaha aan biyaha ku milmin si siman ugu milmaan biyaha si ay u sameeyaan emulsion waxaa loo yaqaan emulsification. Isqurxinta, emulsifiers-ka waxaa inta badan loo isticmaalaa soo saarista kareemada iyo looshinada. Noocyada caadiga ah sida kareemka baaba'aya ee budada ah iyo kareemka baaba'aya ee "Zhongxing" labaduba waa emulsions O/W (saliid-ku-jira-biyo), kuwaas oo lagu baaba'in karo iyadoo la isticmaalayo emulsifiers anionic sida saabuunta dufanka leh ee aashitada. Baaba'aya saabuunta waxay sahlaysaa in la helo emulsions leh saliid yar, saamaynta baaba'aya ee saabuunta waxay siisaa daxal sare. Kareemada qabow ee ka kooban qayb weyn oo wejiga saliidda ah, emulsions-ku waxay inta badan yihiin nooca W/O (biyo-ku-jira-saliid), kaas oo lanolin dabiici ah - oo leh awooddeeda nuugista biyaha ee xooggan iyo daxal sare - loo dooran karo emulsifier. Waqtigan xaadirka ah, emulsifiers-ka aan ionic ahayn ayaa ah kuwa ugu badan ee la isticmaalo, sababtoo ah ammaankooda iyo cuncunkooda oo hooseeya.
Ifafaalaha ay ku badan tahay milanka walxaha milmi kara ama aan milmi karin waxaa loogu yeeraa milmi-saaridda. Marka surfactants lagu daro biyaha, xiisadda dusha sare ee biyuhu waxay marka hore si xoog leh hoos ugu dhacdaa, ka dibna isku-darka molecules-ka surfactant-ka ee loo yaqaan micelles ayaa bilaabma inay sameysmaan. Isu-ururinta surfactant-ka ee ay ka dhacdo sameynta micelle waxaa loo yaqaan isku-ururinta micelle ee muhiimka ah (CMC). Marka fiirsashada surfactant-ku ay gaarto CMC, micelles-ku waxay ku qaban karaan saliidda ama walxaha adag dhammaadka hydrophobic ee molecules-kooda, taasoo kor u qaadaysa milmi-saarka walxaha milmi-la'aanta ah ama aan milmi karin.
Isqurxinta, mileyaasha waxaa inta badan loo isticmaalaa soo saarista toners, saliidaha timaha, iyo diyaarinta koritaanka timaha iyo hagaajinta timaha. Sababtoo ah maaddooyinka qurxinta saliidda leh - sida caraf udgoonka, dufanka, iyo fiitamiinnada milma saliidda - waxay ku kala duwan yihiin qaab-dhismeedka iyo kala duwanaanshaha, qaababka milmidooda sidoo kale way kala duwan yihiin; sidaa darteed, surfactants-ka ku habboon waa in loo doortaa sidii mileyaasha. Tusaale ahaan, maadaama toners-ku ay milmaan udgoonka, saliidaha, iyo daawooyinka, ethers-ka alkyl polyoxyethylene ayaa loo isticmaali karaa ujeeddadaas. In kasta oo ethers-ka alkylphenol polyoxyethylene (nooca OP, nooca TX) ay leeyihiin awood milmi xooggan, haddana waxay dhibsadaan indhaha sidaas darteedna guud ahaan waa laga fogaadaa. Intaa waxaa dheer, waxyaabaha laga soo saaro amphoteric ee ku salaysan saliidda castor waxay muujiyaan milmi aad u fiican saliidaha udgoonka iyo saliidaha khudradda, iyagoo aan indhaha ka xanaajin, waxay ku habboon yihiin diyaarinta shaambooyada khafiifka ah iyo qurxinta kale.
