Ama-surfactantziyizinto ezinesakhiwo samakhemikhali esiyingqayizivele kakhulu futhi zisetshenziswa kabanzi embonini yezimonyo. Zisebenza njengezithako ezisizayo ekwakhiweni kwezimonyo—nakuba zisetshenziswa ngobuningi obuncane, zidlala indima ebalulekile. Ama-surfactants atholakala emikhiqizweni eminingi, okuhlanganisa izihlanzi zobuso, ama-lotion okuthambisa, ama-cream esikhumba, ama-shampoo, ama-conditioner, kanye namazinyo okuxubha. Imisebenzi yazo ezimonyweni iyahlukahluka, okuhlanganisa ikakhulukazi i-emulsification, ukuhlanza, ukukhiqiza amagwebu, ukuncibilikisa, isenzo sokulwa namagciwane, imiphumela yokulwa ne-static, kanye nokusabalala. Ngezansi, sichaza izindima zazo ezine eziyinhloko:
(1) Ukuhlanganiswa kwe-emuls
Kuyini i-emulsification? Njengoba sazi, okhilimu nama-lotion esiwasebenzisa kakhulu ekunakekelweni kwesikhumba aqukethe kokubili izingxenye ezinamafutha kanye nenani elikhulu lamanzi—kuyingxube yamafutha namanzi. Kodwa-ke, kungani singakwazi ukubona amaconsi kawoyela noma amanzi agelezayo ngamehlo enyama? Lokhu kungenxa yokuthi akha uhlelo olusakazeke ngokulinganayo: izingxenye ezinamafutha zisatshalaliswa ngokulinganayo njengamaconsi amancane emanzini, noma amanzi asakazeka ngokulinganayo njengamaconsi amancane emafutheni. Eyokuqala ibizwa ngokuthi i-emulsion yamafutha-emanzini (O/W), kanti eyesibili iyi-emulsion yamanzi-emanzini (W/O). Izimonyo zalolu hlobo zaziwa ngokuthi izimonyo ezisekelwe e-emulsion, uhlobo oluvame kakhulu.
Ngaphansi kwezimo ezivamile, uwoyela namanzi akuhlangani. Uma sekuqediwe, kuyahlukana kube yizingqimba, kwehluleka ukwakha ukuhlakazeka okuzinzile nokulinganayo. Kodwa-ke, kuma-creams nama-lotion (imikhiqizo esekelwe ku-emulsion), izingxenye ezinamafutha nezimanzi zingakha ukuhlakazeka okuxubile kahle, okulinganayo ngenxa yokwengezwa kwama-surfactants. Isakhiwo esiyingqayizivele sama-surfactants sivumela lezi zinto ezingahlangani ukuthi zihlangane ngokufanayo, zidale 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-lotion esiwasebenzisa nsuku zonke.
(2) Ukuhlanza Nokukhipha Igwebu
Amanye ama-surfactants abonisa izakhiwo ezinhle kakhulu zokuhlanza nokukhipha amagwebu. Insipho, isibonelo esaziwayo, uhlobo lwe-surfactant olusetshenziswa kakhulu. Insipho yokugeza kanye nensipho yebha ithembele ezingxenyeni zayo zensipho (ama-surfactants) ukuze ifeze imiphumela yokuhlanza nokukhipha amagwebu. Amanye ama-surfactants ebusweni nawo asebenzisa izingxenye zensipho ukuhlanza. Kodwa-ke, insipho inamandla okuhlanza aqinile, angasusa amafutha ayo emvelo esikhumbeni futhi ingase icasule kancane, okwenza ingafaneleki esikhumbeni esomile noma esibucayi.
Ngaphezu kwalokho, ama-bath gel, ama-shampoo, ama-hand washes, kanye ne-toothpaste konke kuncike kuma-surfactants ukuze kuhlanzwe futhi kukhiqizwe amagwebu.
(3) Ukuncibilika
Ama-surfactant angandisa ukuncibilika kwezinto ezingancibiliki noma ezingancibiliki kahle emanzini, okuzivumela ukuthi zincibilike ngokuphelele futhi zakhe ikhambi elisobala. Lo msebenzi ubizwa ngokuthi ukuncibilika, kanti ama-surfactant awenzayo aziwa ngokuthi ama-solubilizer.
Isibonelo, uma sifuna ukwengeza ingxenye yamafutha efumisa kakhulu ku-toner ecacile, uwoyela ngeke uncibilike emanzini kodwa esikhundleni salokho uzontanta njengamaconsi amancane ebusweni. Ngokusebenzisa umphumela wokuncibilikisa wama-surfactants, singafaka uwoyela ku-toner, okuholela ekubukekeni okucacile nokusobala. Kodwa-ke, kubalulekile ukuqaphela ukuthi inani lamafutha angancibilika ngokuncibilikisa lilinganiselwe—inani elikhulu kunzima ukuncibilikisa ngokuphelele emanzini. Ngakho-ke, njengoba okuqukethwe uwoyela kukhuphuka, inani le-surfactant kumele likhuphuke ukuze lincibilikise uwoyela namanzi. Yingakho amanye ama-toner ebonakala engabonakali noma emhlophe njengobisi: aqukethe ingxenye ephezulu yamafutha afumisayo, ama-surfactants awancibilikisa ngamanzi.
