Umkhuba wokukhula okuqhubekayoama-surfactantemhlabeni wonke udale indawo efanelekile yangaphandle yokuthuthukiswa nokwandiswa kwemboni yezimonyo, ngezidingo eziqinile zesakhiwo somkhiqizo, izinhlobo, ukusebenza kanye nobuchwepheshe. Ngakho-ke, kubalulekile ukuthuthukisa ngokuhlelekile ama-surfactants aphephile, athambile, alula ukubola futhi anemisebenzi ekhethekile, ukuze kubekwe isisekelo semfundiso yokuthuthukiswa nokusetshenziswa kwemikhiqizo emisha. Kuzobekwa phambili ukuthuthukiswa kwama-surfactants e-glycoside, futhi kungathuthukiswa ama-surfactants ahlukahlukene e-polyol kanye notshwala; ucwaningo oluhlelekile kanye nokuthuthukiswa kwama-surfactants e-soya phospholipid kuzokwenziwa; kuzothuthukiswa uchungechunge lwemikhiqizo ye-sucrose fatty acid ester, kuzothuthukiswa ucwaningo ngobuchwepheshe bokuhlanganisa, futhi ububanzi bokusetshenziswa kwemikhiqizo ekhona buzokwandiswa.
Ukuhlanganiswa kwe-Emulsificationkubhekisela esimweni lapho izinto ezingancibiliki emanzini zihlanganiswa khona ngokulinganayo emanzini ukuze zenze i-emulsion. Ezimonyweni, ama-emulsifier asetshenziswa kakhulu ukukhiqiza okhilimu nama-lotion. Okhilimu abancibilika ngempuphu evamile kanye nokhilimu abancibilika abangathathi hlangothi bonke bangama-emulsion kawoyela emanzini (O/W), angahlanganiswa ngensipho ye-anionic emulsifier fatty acid (insipho). Kulula kakhulu ukulungiselela ama-emulsion anokuqukethwe okuphansi kwamafutha kusetshenziswa insipho, futhi umphumela we-gelling wensipho unganika ama-emulsion i-viscosity ephezulu. Okhilimu ababandayo abaqukethe inani elikhulu lesigaba samafutha ikakhulukazi ama-emulsion kawoyela (W/O), angahlanganiswa nge-lanolin yemvelo equkethe ukumuncwa kwamanzi okunamandla kanye ne-viscosity ephezulu. Ama-emulsifier angewona ama-ionic yiwona asetshenziswa kakhulu njengamanje ngenxa yokuphepha kwawo kanye nokucasuka okuncane. Ukuncibilika kubhekisela esimweni sokuthi izinto ezincibilika kancane noma ezingancibiliki zithola ukuncibilika okukhulu. Uma ama-surfactant engezwa emanzini, ukucindezelwa kwamanzi kwehla kakhulu ekuqaleni, kulandelwe ukwakheka kwama-micelles ahlanganiswe ama-molecule e-surfactant. Ukuhlushwa kwama-surfactant adingekayo ekwakhekeni kwe-micelle kubizwa ngokuthi ukuhlushwa kwe-micelle okubalulekile. Lapho ukuhlushwa kwe-surfactant kufinyelela ekuhlushweni kwe-micelle okubalulekile, ama-micelles angamunca uwoyela noma izinhlayiya eziqinile emaphethelweni azo e-lipophilic, ngaleyo ndlela kuthuthukiswe ukuncibilika kwezinto ezincibilikayo noma ezingancibiliki kancane.
IzinyibilikisiEzimonyweni zobuhle zisetshenziswa kakhulu ekukhiqizweni kwamafutha esikhumba, amafutha okukhulisa izinwele kanye nezinto ezondla izinwele. Izithako zamafutha ezimonyweni zobuhle, njengeziqholo, amafutha kanye namavithamini ancibilika kumafutha, zakha izinhlelo ezahlukene zokuncibilika ngenxa yokungafani kwezakhiwo zazo kanye nama-polarities, ngakho-ke ama-surfactant afanele kumele akhethwe njengezincibilikisi. Isibonelo, izinto ezincibilikisiwe ezimonyweni zobuhle zifaka amakha, amafutha kanye nezithako zokwelapha, ngakho-ke ama-alkyl polyoxyethylene ethers angasetshenziswa ukuze ancibilikisiwe. Nakuba ama-alkylphenol polyoxyethylene ethers (uchungechunge lwe-OP, uchungechunge lwe-TX) anamandla amakhulu okuncibilikisa, ngokuvamile awasetshenziswa njengoba ecasula amehlo. Ngaphezu kwalokho, ama-amphoteric derivatives asekelwe kumafutha e-castor abonisa ukuncibilika okuhle kakhulu kwamafutha ephunga namafutha emifino, futhi ama-surfactant anjalo awacasuli amehlo, okwenza afaneleke ukukhiqiza ama-shampoo athambile kanye neminye imikhiqizo yezimonyo.
