Ama-surfactantsyizinto ezinokwakheka kwamakhemikhali ehluke kakhulu futhi zisetshenziswa kakhulu embonini yezimonyo. Zisebenza njengezithako ezisiza ekwenziweni kwezimonyo—nakuba zisetshenziswa ngamanani amancane, zidlala indima ebalulekile. Ama-surfactants atholakala emikhiqizweni eminingi, okuhlanganisa izinto zokuhlanza ubuso, izinto zokugcoba ezithambisayo, okhilimu besikhumba, ama-shampoos, ama-conditioner kanye nomuthi wokuxubha. Imisebenzi yabo ezimonyoni ihlukene, ikakhulukazi ihlanganisa i-emulsification, ukuhlanza, ukukhipha amagwebu, i-solubilization, isenzo se-antibacterial, imiphumela ye-antistatic, nokuhlakazeka. Ngezansi, sichaza izindima zabo ezine eziyinhloko:
(1) Ukulingiswa
Kuyini i-emulsification? Njengoba sazi, okhilimu nezinto zokugcoba esivame ukuzisebenzisa ekunakekeleni isikhumba ziqukethe kokubili izingxenye ezinamafutha kanye nenani elikhulu lamanzi—kuyingxube kawoyela namanzi. Nokho, kungani singenakuwabona amaconsi kawoyela noma amanzi agelezayo ngeso lenyama? Lokhu kungenxa yokuthi benza uhlelo oluhlakazekile olufana kakhulu: izingxenye ezinamafutha zisakazwa ngokulinganayo njengamaconsi amancane emanzini, noma amanzi ahlakazeke ngokulinganayo njengamaconsi amancane emafutheni. Owokuqala ubizwa ngokuthi i-emulsion yamafutha emanzini (O/W), kanti eyesibili i-emulsion yamanzi ngamafutha (W/O). Izimonyo zalolu hlobo zaziwa ngokuthi izimonyo ezisekelwe emulsion, izinhlobonhlobo ezivame kakhulu.
Ngaphansi kwezimo ezijwayelekile, uwoyela namanzi akuhambisani. Uma ziyeka ukunyakazisa, ziyahlukana zibe izingqimba, zehluleke ukwakha uhlaka oluzinzile, olufana nolunye. Kodwa-ke, kuma-creams nama-lotions (imikhiqizo esekelwe emulsion), izingxenye ezinamafutha kanye nama-aqueous zingakha ukuxubana kahle, ukuhlakazeka okufanayo ngenxa yokwengezwa kwama-surfactants. Isakhiwo esiyingqayizivele sama-surfactants sivumela lezi zinto ezingenakulinganiswa ukuthi zihlangane ngokufanayo, zenze uhlelo lokuhlakazeka oluzinzile-okungukuthi, i-emulsion. Lo msebenzi wama-surfactants ubizwa ngokuthi i-emulsification, kanti ama-surfactants enza le ndima abizwa ngokuthi ama-emulsifiers. Ngakho-ke, ama-surfactants akhona kuma-creams nama-lotions esiwasebenzisa nsuku zonke.
(2) Ukuhlanza kanye Nokukhihliza Amagwebu
Amanye ama-surfactants abonisa izakhiwo ezinhle kakhulu zokuhlanza nokukhipha amagwebu. Insipho, isibonelo esaziwayo, iwuhlobo olusetshenziswa kakhulu lwe-surfactant. Izinsipho zokugeza nezinsipho zebha zithembele ezingxenyeni zazo zensipho (ama-surfactants) ukuze kuzuzwe imiphumela yokuhlanza kanye negwebu. Ezinye izinto zokuhlanza ubuso nazo zisebenzisa izingxenye zensipho ukuze zihlanzeke. Kodwa-ke, insipho inamandla okuhlanza aqinile, angakhumula isikhumba samafutha ayo emvelo futhi angase acasule kancane, ayenze ingafaneleki esikhumbeni esomile noma esibucayi.
Ukwengeza, ama-gel okugeza, ama-shampoos, iziwasha zezandla, kanye nomuthi wokuxubha amazinyo konke kuncike ezintweni ezisetshenziswayo ekuhlanzeni nasekukhipheni amagwebu.
(3) Ukuqiniswa
Ama-surfactants angakhuphula ukunyibilika kwezinto ezingancibiliki noma ezingancibiliki kahle emanzini, okuzivumela ukuthi zincibilike ngokuphelele futhi zakhe isixazululo esisobala. Lo msebenzi ubizwa ngokuthi i-solubilization, futhi ama-surfactants awenzayo aziwa ngokuthi ama-solubilizer.
Isibonelo, uma sifuna ukungeza ingxenye enamafutha athambisa kakhulu ku-toner ecacile, uwoyela ngeke ancibilike emanzini kodwa uzontanta njengamathonsi amancane phezulu. Ngokusebenzisa umphumela wokuncibilikisa wama-surfactants, singahlanganisa uwoyela kwi-toner, okuholela ekubukekeni okucacile, okusobala. Kodwa-ke, kubalulekile ukuqaphela ukuthi inani lamafutha angancibilika ngokusebenzisa i-solubilization lilinganiselwe-inani elikhulu kunzima ukuhlakazeka ngokugcwele emanzini. Ngakho-ke, njengoba okuqukethwe kwamafutha kwanda, inani le-surfactant kufanele likhuphuke ukuze lifake uwoyela namanzi. Yingakho amanye amathoni ebonakala e-opaque noma emhlophe e-milky: aqukethe ingxenye ephezulu yamafutha athambisayo, ama-surfactants awafaka ngamanzi.
