Ii-surfactantsZizinto ezinesakhiwo seekhemikhali esahlukileyo kwaye zisetyenziswa kakhulu kwishishini lezinto zokuthambisa. Zisebenza njengezithako ezincedisayo kwimilo yokuthambisa—nangona zisetyenziswa ngobuninzi, zidlala indima ebalulekileyo. Izinto zokuthambisa zifumaneka kwiimveliso ezininzi, kuquka izinto zokucoca ubuso, izinto zokuthambisa, iikhrimu zolusu, iishampu, izinto zokuthambisa, kunye ne-toothpaste. Imisebenzi yazo kwizinto zokuthambisa yahlukile, ngokuyintloko ibandakanya ukuxuba, ukucoca, ukufutha, ukunyibilikisa, isenzo sokulwa neentsholongwane, iziphumo zokulwa ne-static, kunye nokusasazwa. Ngezantsi, sichaza imisebenzi yazo emine ephambili:
(1) Ukuhlanganiswa kwe-emuls
Yintoni i-emulsification? Njengoko sisazi, iikhrimu kunye neeloshini esizisebenzisa rhoqo ekunyamekeleni ulusu ziqulethe zombini izinto ezinamafutha kunye namanzi amaninzi—ziyimixube yeoyile namanzi. Sekunjalo, kutheni singenakubona amathontsi eoyile okanye amanzi aphumayo ngamehlo enyama? Oku kungenxa yokuba zenza inkqubo esasazekileyo efanayo: izinto ezinamafutha zisasazeke ngokulinganayo njengamathontsi amancinci emanzini, okanye amanzi asasazeke ngokulinganayo njengamathontsi amancinci kwioyile. Eyokuqala ibizwa ngokuba yi-oyile-in-water(O/W) emulsion, ngelixa eyesibini iyi-water-in-oyile(W/O) emulsion. Ii-cosmetics zolu hlobo zaziwa ngokuba zii-cosmetics ezisekelwe kwi-emulsion, uhlobo oluqhelekileyo.
Kwiimeko eziqhelekileyo, ioyile namanzi azixubeki. Nje ukuba zixutywe, ziyahlukana zibe ziingqimba, zingakwazi ukwenza ukusasazwa okuzinzileyo nokulinganayo. Nangona kunjalo, kwiikhrimu nakwiiloshini (iimveliso ezisekwe kwi-emulsion), izinto ezinamafutha nezimanzi zinokwenza ukusasazwa okuxutyiweyo nokulinganayo ngenxa yokongezwa kwee-surfactants. Ulwakhiwo olukhethekileyo lwee-surfactants luvumela ezi zinto zingaxubekiyo ukuba zixubane ngokulinganayo, zidale inkqubo yokusasazwa ezinzileyo—oko kukuthi, i-emulsion. Lo msebenzi wee-surfactants ubizwa ngokuba yi-emulsification, kwaye ii-surfactants ezenza le ndima zibizwa ngokuba zii-emulsifiers. Ngoko ke, ii-surfactants zikhona kwiikhrimu nakwiiloshini esizisebenzisa imihla ngemihla.
(2) Ukucoca kunye nokuGweba
Ezinye ii-surfactants zibonisa iimpawu ezintle zokucoca kunye nokukhupha igwebu. Isepha, umzekelo owaziwayo, luhlobo lwe-surfactant olusetyenziswa kakhulu. Iisepha zokuhlamba kunye neesepha zebha zixhomekeke kwizakhi zazo zesepha (ii-surfactants) ukuze zifumane iziphumo zokucoca kunye nokukhupha igwebu. Ezinye izicoci zobuso zisebenzisa nezixhobo zesepha ukucoca. Nangona kunjalo, isepha inamandla okucoca aqinileyo, anokususa iioyile zendalo zesikhumba kwaye inokuba nomsindo kancinci, nto leyo enokuyenza ingafanelekanga kulusu olomileyo okanye olunobuthathaka.
Ukongeza, ii-bath gels, ii-shampoos, ii-hand washes, kunye ne-toothpaste zonke zixhomekeke kwi-surfactants ukuze zicoce kwaye zikhuphe amagwebu.
(3) Ukunyibilika
Izinto ezinyibilikayo zinokunyusa ukunyibilika kwezinto ezinganyibilikiyo okanye ezinganyibilikiyo kakuhle emanzini, nto leyo evumela ukuba zinyibilike ngokupheleleyo kwaye zenze isisombululo esicacileyo. Lo msebenzi ubizwa ngokuba yi-solubilization, kwaye izinto ezinyibilikayo ezenza lo msebenzi zaziwa ngokuba zii-solubilizers.
Umzekelo, ukuba sifuna ukongeza i-oyile efumisa kakhulu kwi-toner ecacileyo, ioyile ayizukunyibilika emanzini kodwa endaweni yoko iya kudada njengamathontsi amancinci kumphezulu. Ngokusebenzisa isiphumo sokunyibilikisa se-surfactants, singayifaka ioyile kwi-toner, nto leyo ebangela ukubonakala okucacileyo nokucacileyo. Nangona kunjalo, kubalulekile ukuqaphela ukuba ubungakanani beoyile enokunyibilikiswa ngokunyibilikisa buncinci—ubuninzi obukhulu kunzima ukunyibilikisa ngokupheleleyo emanzini. Ke ngoko, njengoko umxholo weoyile usanda, ubungakanani be-surfactant kufuneka bunyuke ukuze i-oyile namanzi zinyibilike. Yingakho ezinye ii-toner zibonakala zimhlophe okanye zimhlophe njengobisi: ziqulathe inani eliphezulu leoyile ezifumisayo, ezithi ii-surfactants zinyibilikise ngamanzi.
