2.2 Mowa wamafuta ndi alkoxylate sulfate
Mafuta a mowa ndi alkoxylate sulphate ndi gulu la sulphate ester surfactants okonzedwa ndi sulfate anachita mowa hydroxyl gulu ndi sulfure trioxide. mankhwala wamba ndi mafuta mowa sulphate ndi mafuta mowa polyoxygen Vinyl etha sulfate ndi mafuta mowa polyoxypropylene polyoxyethylene etha sulfate, etc.

2.2.1 Mafuta a mowa sulfate
Fatty Alcohol Sulfate (AS) ndi mtundu wazinthu zomwe zimachokera ku mowa wamafuta kudzera mu SO3 sulfation ndi neutralization reaction. Mowa wamafuta omwe amagwiritsidwa ntchito kwambiri ndi coco C12-14. Mankhwalawa nthawi zambiri amatchedwa K12. Zinthu zazikulu zomwe zimagwira pamsika ndi 28 % ~ 30% yamadzimadzi ndipo zinthu zogwira ntchito ndizoposa 90% ufa. Monga chopangira cha anionic chochita bwino kwambiri, K12 imagwiritsa ntchito mankhwala otsukira mano, zotsukira, zomangira gypsum ndi biomedicine.

2.2.2 Mowa wochuluka wa polyoxyethylene ether sulfate
Fatty alcohol polyoxyethylene ether sulfate (AES) ndi mtundu wa surfactant wotengedwa kuchokera ku mafuta oledzeretsa a polyoxyethylene ether (EO nthawi zambiri amakhala 1 ~ 3) kupyolera mu SO3 sulfation ndi neutralization. Pakalipano, malonda pamsika wapakhomo ali ndi mitundu iwiri: phala lokhala ndi pafupifupi 70% ndi madzi okhala ndi pafupifupi 28%.
Poyerekeza ndi AS, kuyambitsidwa kwa gulu la EO mu molekyulu kumapangitsa AES kukhala bwino kwambiri polimbana ndi madzi olimba komanso kupsa mtima. AES ili ndi decontamination yabwino, emulsification, kunyowetsa ndi kuchita thovu, ndipo imatha kuwonongeka mosavuta. Amagwiritsidwa ntchito kwambiri pakutsuka m'nyumba ndi chisamaliro chaumwini. Mchere wa AES ammonium umakhala ndi vuto la pakhungu pang'ono, ndipo umagwiritsidwa ntchito makamaka mu ma shampoos apamwamba komanso kutsuka thupi.

2.2.3 Mowa wochuluka wa polyoxypropylene polyoxyethylene ether sulfate
Fatty alcohol polyoxypropylene polyoxyethylene ether sulfate, wotchedwanso Extended acid salt surfactant, ndi mtundu wa surfactant womwe waphunzira kunja kwa zaka zoposa khumi. Wowonjezera surfactant amatanthauza mtundu wa surfactant yemwe amayambitsa magulu a PO kapena PO-EO pakati pa hydrophobic tail chain ndi gulu la mutu wa hydrophilic wa ionic surfactant. Lingaliro la "Extended" linaperekedwa ndi Dr. Salager wa ku Venezuela mu 1995. Cholinga chake ndi kukulitsa mndandanda wa hydrophobic wa surfactants, potero kupititsa patsogolo kuyanjana kwa surfactants ndi mafuta ndi madzi. Mtundu uwu wa surfactant uli ndi izi: kuthekera kolimba kwambiri kwa solubilization, kupsinjika kopitilira muyeso ndi mafuta osiyanasiyana (<10-2mn>
