2.2 Barasa mai kitse da alkoxylate sulfate
Barasa mai kitse da alkoxylate sulfate rukuni ne na sulfate ester surfactants wanda aka shirya ta hanyar sulfation na ƙungiyar hydroxyl barasa tare da sulfur trioxide. Abubuwan da aka saba amfani da su sune m barasa sulfate da m barasa polyoxygen Vinyl ether sulfate da m barasa polyoxypropylene polyoxyethylene ether sulfate, da dai sauransu.

2.2.1 Sulfate mai barasa
Sulfate Alcohol Sulfate (AS) wani nau'in samfuri ne da aka samo daga barasa mai kitse ta hanyar SO3 sulfation da halayen neutralization. Barasa mai kitse da aka saba amfani da ita shine coco C12-14. Ana kiran samfurin sau da yawa K12. Babban abubuwan da ke aiki akan kasuwa sune samfuran ruwa 28% ~ 30% kuma abubuwa masu aiki sun fi samfuran foda sama da 90%. A matsayin anionic surfactant tare da kyakkyawan aiki, K12 yana da aikace-aikace a cikin man goge baki, wanki, kayan gini na gypsum da biomedicine.

2.2.2 Fatty barasa polyoxyethylene ether sulfate
Fatty barasa polyoxyethylene ether sulfate (AES) wani nau'i ne na surfactant samu daga m barasa polyoxyethylene ether (EO yawanci 1 ~ 3) ta hanyar SO3 sulfation da neutralization. A halin yanzu, samfurin a kasuwa na gida yana da nau'i biyu: manna tare da abun ciki na kusan 70% da ruwa tare da abun ciki na kusan 28%.
Idan aka kwatanta da AS, gabatarwar ƙungiyar EO a cikin kwayoyin halitta yana sa AES ya inganta sosai dangane da juriya ga ruwa mai wuya da fushi. AES yana da kyawawa mai kyau, emulsification, jika da kayan kumfa, kuma yana da sauƙin haɓakawa. Ana amfani dashi sosai a cikin wanke gida da kulawa na sirri. Gishirin AES ammonium yana da ɗan haushin fata, kuma ana amfani dashi galibi a cikin wasu manyan shamfu da wankin jiki.

2.2.3 Fatty barasa polyoxypropylene polyoxyethylene ether sulfate
Fatty barasa polyoxypropylene polyoxyethylene ether sulfate, kuma aka sani da Extended acid gishiri surfactant, wani nau'i ne na surfactant da aka yi nazari a kasashen waje fiye da shekaru goma. Extended surfactant yana nufin nau'in surfactant wanda ke gabatar da ƙungiyoyin PO ko PO-EO tsakanin sarkar wutsiya ta hydrophobic da ƙungiyar shugaban hydrophilic na ionic surfactant. Manufar "Extended" ta Venezuelan Dr. Salager ne ya gabatar da shi a cikin 1995. Yana nufin ƙaddamar da sarkar hydrophobic na surfactants, don haka inganta hulɗar surfactants tare da man fetur da ruwa. Wannan nau'in surfactant yana da fasalulluka masu zuwa: ƙarfin solubilization mai ƙarfi mai ƙarfi, tashin hankali na tsaka-tsakin tsaka-tsaki tare da mai daban-daban (<10-2mn>
