2.2 Fatty cawv thiab nws cov alkoxylate sulfate
Fatty cawv thiab nws cov alkoxylate sulfate yog ib chav kawm ntawm sulfate ester surfactants npaj los ntawm sulfation cov tshuaj tiv thaiv ntawm cawv hydroxyl pawg nrog sulfur trioxide. Cov khoom lag luam yog fatty cawv sulfate thiab fatty cawv polyoxygen Vinyl ether sulfate thiab fatty cawv polyoxypropylene polyoxyethylene ether sulfate, thiab lwm yam.

2.2.1 Fatty cawv sulfate
Fatty Alcohol Sulfate (AS) yog ib yam khoom tau los ntawm cov dej cawv fatty cawv los ntawm SO3 sulfation thiab neutralization cov tshuaj tiv thaiv. Cov dej cawv uas nquag siv yog coco C12-14. Cov khoom no feem ntau hu ua K12. Cov khoom siv tseem ceeb hauv kev ua lag luam yog 28% ~ 30% cov khoom ua kua thiab cov tshuaj nquag muaj ntau dua 90% cov khoom siv hmoov. Raws li anionic surfactant nrog kev ua tau zoo, K12 muaj kev siv tshuaj txhuam hniav, tshuaj ntxuav tes, gypsum tsev cov ntaub ntawv thiab biomedicine.

2.2.2 Fatty alcohol polyoxyethylene ether sulfate
Fatty alcohol polyoxyethylene ether sulfate (AES) yog ib hom surfactant tau los ntawm fatty cawv polyoxyethylene ether (EO feem ntau yog 1 ~ 3) los ntawm SO3 sulfation thiab neutralization. Tam sim no, cov khoom lag luam hauv kev lag luam hauv tsev muaj ob hom: muab tshuaj txhuam nrog cov ntsiab lus ntawm 70% thiab cov kua nrog cov ntsiab lus ntawm 28%.
Piv nrog rau AS, kev taw qhia ntawm EO pab pawg hauv cov molecule ua rau AES zoo heev nyob rau hauv cov nqe lus ntawm kev tiv thaiv rau cov dej tawv thiab khaus khaus. AES muaj zoo decontamination, emulsification, wetting thiab foaming zog, thiab yog yooj yim biodegradable. Nws yog dav siv hauv tsev ntxhua khaub ncaws thiab tu tus kheej. AES ammonium ntsev muaj me ntsis ntawm daim tawv nqaij khaus, thiab yog siv nyob rau hauv ib co high-end tshuaj zawv plaub hau thiab lub cev ntxuav.

2.2.3 Fatty alcohol polyoxypropylene polyoxyethylene ether sulfate
Fatty alcohol polyoxypropylene polyoxyethylene ether sulfate, tseem hu ua Extended acid ntsev surfactant, yog ib hom surfactant uas tau kawm txawv teb chaws rau ntau tshaj kaum xyoo. Extended surfactant yog hais txog ib hom surfactant uas qhia txog PO lossis PO-EO pawg ntawm cov saw hlau hydrophobic thiab pawg hydrophilic taub hau ntawm ionic surfactant. Lub tswv yim ntawm "Extended" yog npaj los ntawm Venezuelan Dr. Salager nyob rau hauv 1995. Nws aims mus cuag cov hydrophobic saw ntawm surfactants, yog li pab txhawb kev sib cuam tshuam ntawm surfactants nrog roj thiab dej. Hom surfactant no muaj cov yam ntxwv hauv qab no: muaj zog solubilization muaj peev xwm, ultra-low interfacial nro nrog ntau cov roj (<10-2mn>
