2.2 Joala bo mafura le alkoxylate sulfate ea eona
Joala bo mafura le sulfate ea eona ea alkoxylate ke sehlopha sa li-surfactants tsa sulfate ester tse lokiselitsoeng ke karabelo ea sulfation ea sehlopha sa joala sa hydroxyl se nang le sulfur trioxide. Lihlahisoa tse tloaelehileng ke mafura a joala a sulfate le mafura a joala a polyoxygen Vinyl ether sulfate le mafura a joala a polyoxypropylene polyoxyethylene ether sulfate, joalo-joalo.

2.2.1 Sulfate ea joala e mafura
Fatty Alcohol Sulfate (AS) ke mofuta oa sehlahisoa se fumanoang joala bo mafura ka SO3 sulfation le neutralization reaction. Hangata, joala bo mafura bo sebelisoa ke coco C12-14. Hangata sehlahisoa se bitsoa K12. Lintho tse ka sehloohong tse sebetsang 'marakeng ke 28% ~ 30% lihlahisoa tsa metsi le lintho tse sebetsang ke lihlahisoa tse fetang 90% tsa phofo. Jwaloka sesebediswa sa anionic se nang le tshebetso e ntle haholo, K12 e na le ditshebediso ka hara sesepa sa meno, dihlwekisi, thepa ya kaho ya gypsum le biomedicine.

2.2.2 joala bo mafura polyoxyethylene ether sulfate
Mafura a joala a polyoxyethylene ether sulfate (AES) ke mofuta oa surfactant e fumanoang ho mafura a joala a polyoxyethylene ether (EO hangata ke 1~3) ka SO3 sulfation le neutralization. Hona joale, sehlahisoa 'marakeng oa lehae se na le mefuta e' meli: peista e nang le litaba tse ka bang 70% le mokelikeli o nang le litaba tse ka bang 28%.
Ha ho bapisoa le AS, ho kenyelletsoa ha sehlopha sa EO ka molek'hule ho etsa hore AES e ntlafatse haholo tabeng ea ho hanyetsa metsi a thata le ho halefa. AES e na le lintho tse ntle tsa ho tlosa tšilafalo, emulsification, ho kolobisa le ho phophoma, 'me e senyeha habonolo. E sebelisoa haholo ho hlatsoa malapa le tlhokomelo ea botho. Letsoai la AES ammonium le na le letlalo le hlabang hanyane, 'me le sebelisoa haholo lishampong tse ling tsa maemo a holimo le lihlapa tsa 'mele.

2.2.3 Joala bo mafura polyoxypropylene polyoxyethylene ether sulfate
Mafura a joala a polyoxypropylene polyoxyethylene ether sulfate, eo hape e tsejoang e le Extended acid salt surfactant, ke mofuta oa surfactant o 'nileng oa ithutoa linaheng tse ling ka lilemo tse fetang leshome. Extended surfactant e bolela mofuta oa surfactant e hlahisang lihlopha tsa PO kapa PO-EO pakeng tsa ketane ea hydrophobic tail le sehlopha sa hlooho sa hydrophilic sa ionic surfactant. Khopolo ea "E atolositsoeng" e ile ea hlahisoa ke Dr. Salager oa Venezuela ka 1995. E ikemiselitse ho atolosa ketane ea hydrophobic ea li-surfactants, ka hona ho matlafatsa ho sebelisana ha li-surfactants ka oli le metsi. Mofuta ona oa surfactant o na le likarolo tse latelang: bokhoni bo matla haholo ba ho kopanya, tsitsipano e tlase ea sefahleho e nang le lioli tse fapaneng (<10-2mn>
