Inkqubela yokukhula okuzinzileyoizinto ezibangela ukudumbaIhlabathi liphela lidale imeko-bume efanelekileyo yangaphandle yophuhliso nokwandiswa kweshishini lezinto zokuthambisa, kunye neemfuno ezingqongqo ngakumbi zesakhiwo semveliso, iintlobo ngeentlobo, ukusebenza kunye netekhnoloji. Ke ngoko, kuyimfuneko ukuphuhlisa ngokucwangcisiweyo izinto ezi-surfactants ezikhuselekileyo, ezithambileyo, ezinokubola ngokulula kwaye zinemisebenzi ekhethekileyo, ukuze kubekwe isiseko sethiyori sophuhliso kunye nokusetyenziswa kweemveliso ezintsha. Kuya kujongwa phambili uphuhliso lwezinto ezi-surfactants ze-glycoside, kwaye iintlobo ngeentlobo zezinto ezi-surfactants ze-polyol kunye ne-alcohol zinokuphuhliswa; uphando olucwangcisiweyo kunye nophuhliso lwezinto ezi-surfactants ze-soya phospholipid ziya kwenziwa; uthotho lweemveliso ze-sucrose fatty acid ester ziya kuphuhliswa, uphando malunga netekhnoloji ezidityanisiweyo luya kwandiswa, kwaye umda wokusetyenziswa kweemveliso ezikhoyo uya kwandiswa.
Ukuhlanganiswa kwe-emulsificationibhekisa kwinto apho izinto ezinganyibilikiyo emanzini zixutywa ngokulinganayo emanzini ukuze zenze i-emulsion. Kwizinto zokuthambisa, ii-emulsifiers zisetyenziselwa kakhulu ukuvelisa iikhrimu kunye neelotion. Iikhrimu eziguquguqukayo zomgubo oqhelekileyo kunye neekhrimu eziguquguqukayo ezingathathi cala zonke ziyi-emulsions ze-oyile-emanzini (O/W), ezinokuxutywa nge-anionic emulsifier fatty acid (isepha). Kulula kakhulu ukulungiselela ii-emulsions ezinomthamo ophantsi weoyile usebenzisa isepha, kwaye isiphumo se-gelling sesepha sinokunika ii-emulsions i-viscosity ephezulu. Iikhrimu ezibandayo eziqulathe inani elikhulu le-oyile ikakhulu zii-emulsions ze-water-in-oil (W/O), ezinokuxutywa nge-lanolin yendalo enokufunxwa kwamanzi okunamandla kunye ne-viscosity ephezulu. Ii-emulsifiers ezingezizo ze-ionic zezona zisetyenziswa kakhulu okwangoku ngenxa yokhuseleko lwazo kunye nokucaphuka okuncinci. Ukunyibilika kubhekisa kwinto yokuba izinto ezinyibilikayo kancinci okanye ezinganyibilikiyo zifumana ukunyibilika okwandisiweyo. Xa ii-surfactants zongezwa emanzini, uxinzelelo lomphezulu wamanzi luyehla kakhulu ekuqaleni, kulandele ukwakheka kwee-micelles ezidityaniswe zii-molecules ze-surfactant. Uxinzelelo lwee-surfactants ezifunekayo ekwakhiweni kwe-micelle lubizwa ngokuba yi-critical micelle concentration. Xa uxinano lwe-surfactant lufikelela kuxinano lwe-micelle ebalulekileyo, ii-micelles zinokufunxa ioyile okanye amasuntswana aqinileyo kwiziphelo zazo ze-lipophilic, ngaloo ndlela ziphucula ukunyibilika kwezinto ezinyibilikayo kancinci okanye ezinganyibilikiyo.
IzinyibilikisiKwizinto zokuthambisa zisetyenziswa kakhulu ekuveliseni izinto zokuthambisa ulusu, iioyile zokukhulisa iinwele kunye nezinto ezondla iinwele. Izithako zeoyile kwizithambiso, ezifana neziqholo, iioyile kunye neevithamini ezinyibilikayo kwioyile, zenza iinkqubo ezahlukeneyo zokuthambisa ngenxa yokungafani kwezakhiwo zazo kunye nee-polarity, ngoko ke ii-surfactants ezifanelekileyo kufuneka zikhethwe njengezinyibilikisi. Umzekelo, izinto eziza kunyibilikiswa kwi-skin lotions ziquka iziqholo, iioyile kunye nezithako zonyango, ngoko ke ii-alkyl polyoxyethylene ethers zingasetyenziswa ukunyibilikisa. Nangona ii-alkylphenol polyoxyethylene ethers (OP series, TX series) zinamandla okunyibilikisa, azisetyenziswa kuba ziyawacaphukisa amehlo. Ukongeza, ii-amphoteric derivatives ezisekwe kwi-castor oil zibonisa ukunyibilikisa okuhle kakhulu kwiioyile zeziqholo kunye neeoyile zemifuno, kwaye ezo zinto aziwacaphukisi amehlo, nto leyo ezenza zifaneleke ukuvelisa iishampu ezithambileyo kunye nezinye iimveliso zezithambiso.
