Ii-surfactantszizinto ezinokwakheka kweekhemikhali ezikhethekileyo kwaye zisetyenziswa kakhulu kushishino lwezithambiso. Zisebenza njengezithako ezincedisayo kwi-cosmetic formulations-nangona zisetyenziswe ngomlinganiselo omncinci, zidlala indima ebalulekileyo. Izinto zokuthambisa zifumaneka kwiimveliso ezininzi, kubandakanywa izicoci zobuso, izinto zokuthambisa ezithambisayo, iikhrimu zolusu, iishampu, iiconditioners, kunye nentlama yamazinyo. Imisebenzi yabo kwizinto zokuthambisa yahlukile, ngokukodwa ibandakanya i-emulsification, ukucocwa, ukukhupha amagwebu, i-solubilization, i-antibacterial action, i-antistatic effects, kunye nokusabalalisa. Ngezantsi, sichaza iindima zabo ezine eziphambili:
(1) Ukulinganisa
Yintoni emulsification? Njengoko sisazi, iikhrimu kunye nezinto zokuthambisa esiqhele ukuzisebenzisa kwi-skincare ziqulathe izinto ezinamafutha kunye nesixa esikhulu samanzi-ziyimixube yeoli kunye namanzi. Ukanti, kutheni singenakuwabona amathontsi eoli okanye amanzi avuzayo ngeliso lenyama? Oku kungenxa yokuba benza inkqubo esasazekileyo efanayo: izinto ezinamafutha asasazwa ngokulinganayo njengamathontsi amancinci emanzini, okanye amanzi asasazwe ngokulinganayo njengamathontsi amancinci kwi-oyile. Eyangaphambili ibizwa ngokuba yi-oli-in-water (O / W) emulsion, ngelixa i-emulsion yamanzi e-oyile (W / O) i-emulsion. Izithambiso zolu hlobo zaziwa ngokuba zii-emulsion-based cosmetics, ezona ntlobo zixhaphakileyo.
Kwiimeko eziqhelekileyo, ioli kunye namanzi akuhambisani. Emva kokumisa, ziyahlukana zibe ngamacandelo, zisilele ukwenza ukusabalalisa okuzinzileyo, okufanayo. Nangona kunjalo, kwi-creams kunye ne-lotions (imveliso esekelwe kwi-emulsion), i-oily and aqueous components can make the well-mixed, uniform dispersion thanks to add of surfactants. Isakhiwo esikhethekileyo se-surfactants sivumela ezi zinto ezingenakulinganiswa ukuba zidibanise ngokufanayo, zenze inkqubo yokusabalalisa izinzile-oko kukuthi, i-emulsion. Lo msebenzi wee-surfactants ubizwa ngokuba yi-emulsification, kwaye ii-surfactants ezenza le ndima zibizwa ngokuba zi-emulsifiers. Ke, ii-surfactants zikhona kwiikhrimu kunye neloshini esiyisebenzisa yonke imihla.
(2) Ukucocwa nokuFakwa namagwebu
Ezinye ii-surfactants zibonisa iimpawu ezigqwesileyo zokucoca kunye nogwebu. Isepha, umzekelo owaziwayo, luhlobo oluqhelekileyo olusetyenziswayo lwe-surfactant. Iisepha zokuhlambela kunye neesepha zebha zixhomekeke kwizinto zazo zesepha (i-surfactants) ukuze zifezekise ukucoca kunye nemiphumo yokuqhuma. Ezinye izicoci zobuso nazo zisebenzisa iinxalenye zesepha ekucoceni. Nangona kunjalo, isepha inamandla okucoca aqinileyo, anokuthi ahlube ulusu lweoyile yendalo kwaye inokucaphukisa kancinci, iyenze ingafaneleki kwesikhumba esomileyo okanye esibuthathaka.
Ukongeza, iijeli zokuhlambela, iishampu, izixhobo zokuhlambela izandla, kunye nentlama yamazinyo zonke zixhomekeke kwizinto ezixutywayo ukuze zihlanjululwe kunye nezenzo zogwebu.
(3) Ukulungelelanisa
I-surfactants inokunyusa ukunyibilika kwezinto ezinganyibilikiyo okanye ezinganyibiliki kakuhle emanzini, zivumela ukuba zinyibilike ngokupheleleyo kwaye zenze isisombululo esicacileyo. Lo msebenzi ubizwa ngokuba yi-solubilization, kwaye ii-surfactants eziwenzayo zaziwa njenge-solubilizers.
Umzekelo, ukuba sifuna ukongeza i-oyile efumisa kakhulu kwitoner ecacileyo, i-oyile ayisayi kunyibilika emanzini kodwa endaweni yoko iya kudada njengamathontsi amancinci ngaphezulu. Ngokusebenzisa impembelelo ye-solubilizing ye-surfactants, sinokufaka ioli kwi-toner, okubangela ukubonakala okucacileyo, okucacileyo. Nangona kunjalo, kubalulekile ukuba uqaphele ukuba inani leoli elinokuchithwa nge-solubilization lilinganiselwe - ubuninzi obukhulu kunzima ukuchithwa ngokupheleleyo emanzini. Ke ngoko, njengoko umxholo we-oyile usanda, isixa se-surfactant kufuneka siphakame ukuze kufakwe i-oyile kunye namanzi. Yingakho ezinye iitoni zibonakala zimhlophe okanye zimhlophe: ziqulethe inxalenye ephezulu yeeoli ezifumisayo, apho i-surfactants emulsify ngamanzi.
