Kukula kosalekeza kwazinthu zopangira ma surfactantsPadziko lonse lapansi lapanga malo abwino akunja kuti pakhale chitukuko ndi kukulitsa makampani odzola, ndi zofunikira kwambiri pa kapangidwe ka zinthu, mitundu, magwiridwe antchito ndi ukadaulo. Chifukwa chake, ndikofunikira kupanga ma surfactants omwe ndi otetezeka, ofatsa, osavuta kuwonongeka komanso okhala ndi ntchito zapadera, kuti akhazikitse maziko ophunzirira pakupanga ndi kugwiritsa ntchito zinthu zatsopano. Kufunika koyambirira kudzaperekedwa pakupanga ma glycoside surfactants, ndipo ma polyol ndi alcohol surfactants osiyanasiyana atha kupangidwa; kafukufuku wokhazikika ndi chitukuko cha ma soya phospholipid surfactants adzachitika; mndandanda wa zinthu za sucrose fatty acid ester udzapangidwa, kafukufuku waukadaulo wophatikizana udzakulitsidwa, ndipo kuchuluka kwa ntchito za zinthu zomwe zilipo kudzakulitsidwa.
Kusakaniza kwa emulsificationlimatanthauza chochitika chomwe zinthu zosasungunuka m'madzi zimaphatikizidwa mofanana m'madzi kuti apange emulsion. Mu zodzoladzola, ma emulsifier amagwiritsidwa ntchito kwambiri popanga mafuta ndi mafuta odzola. Ma cream odziwika bwino ochotsera ufa ndi mafuta osasungunuka ndi mafuta onse omwe ali mumadzi (O/W), omwe amatha kusungunuka ndi sopo wa anionic emulsifier (sopo). N'zosavuta kukonzekera ma emulsion okhala ndi mafuta ochepa pogwiritsa ntchito sopo, ndipo zotsatira za sopo zimatha kupangitsa ma emulsion kukhala ndi mafuta ambiri. Ma cream ozizira okhala ndi mafuta ambiri nthawi zambiri amakhala ma emulsion amadzi (W/O), omwe amatha kusungunuka ndi lanolin yachilengedwe yokhala ndi kuyamwa kwamphamvu kwa madzi komanso kukhuthala kwakukulu. Ma emulsifier osasinthika ndi omwe amagwiritsidwa ntchito kwambiri pakadali pano chifukwa cha chitetezo chawo komanso kukwiya kochepa. Kusungunuka kumatanthauza chochitika chakuti zinthu zosungunuka pang'ono kapena zosasungunuka zimasungunuka kwambiri. Pamene ma surfactants awonjezeredwa m'madzi, mphamvu ya pamwamba pa madzi imatsika kwambiri poyamba, kutsatiridwa ndi kupangidwa kwa ma micelles ophatikizidwa ndi mamolekyu a surfactant. Kuchuluka kwa ma surfactants ofunikira pakupanga micelle kumatchedwa critical micelle concentration. Pamene kuchuluka kwa surfactant kufika pa critical micelle concentration, ma micelles amatha kuyamwa mafuta kapena tinthu tolimba kumapeto kwawo ophilic, motero kumawonjezera kusungunuka kwa zinthu zomwe zimasungunuka pang'ono kapena zosasungunuka.
ZosungunuliraMu zodzoladzola amagwiritsidwa ntchito kwambiri popanga mafuta odzola pakhungu, mafuta okula tsitsi ndi zinthu zopatsa thanzi tsitsi. Zosakaniza zamafuta mu zodzoladzola, monga zonunkhira, mafuta ndi mavitamini osungunuka ndi mafuta, zimapanga njira zosiyanasiyana zosungunulira chifukwa cha kusiyana kwa kapangidwe kake ndi ma polarities ake, kotero ma surfactants oyenera ayenera kusankhidwa ngati zosungunulira. Mwachitsanzo, zinthu zomwe ziyenera kusungunuka mu mafuta odzola pakhungu zimaphatikizapo zonunkhira, mafuta ndi zosakaniza zamankhwala, kotero ma alkyl polyoxyethylene ethers amatha kugwiritsidwa ntchito kuti asungunuke. Ngakhale alkylphenol polyoxyethylene ethers (OP series, TX series) ali ndi mphamvu yosungunulira kwambiri, nthawi zambiri sagwiritsidwa ntchito chifukwa amakwiyitsa maso. Kuphatikiza apo, amphoteric derivatives yochokera ku mafuta a castor imakhala ndi mphamvu yabwino kwambiri ya mafuta onunkhira ndi mafuta a masamba, ndipo ma surfactants oterewa sakwiyitsa maso, zomwe zimapangitsa kuti akhale oyenera kupanga ma shampu ofatsa ndi zinthu zina zodzikongoletsera.
