2.2 Ko te waipiro ngako me tona alkoxylate sulfate
Ko te waipiro ngako me tona alkoxylate sulfate he karaehe o nga hauhau ester pūkawa ngawha i whakaritea e te tauhohenga whakawhanaunga o te roopu hydroxyl waipiro me te whanariki trioxide. Ko nga hua angamaheni he ngako te waipiro waipiro me te ngako waipiro polyoxygen Vinyl ether sulfate me te waipiro ngako polyoxypropylene polyoxyethylene ether sulfate, etc.

2.2.1 Te waipiro pūkawa ngāwha
Ko te Fatty Alcohol Sulfate (AS) he momo hua ka riro mai i te waipiro ngako na roto i te SO3 sulfatation me te tauhohenga whakaheke. Ko te waipiro ngako e whakamahia nuitia ana ko te koko C12-14. Ko te hua ka kiia ko K12. Ko nga matū kaha matua i runga i te maakete ko te 28 % ~ 30% nga hua wai me nga matū kaha he nui atu i te 90% nga hua paura. I te mea he surfactant anionic me te pai o te mahi, he tono a K12 i roto i te toothpaste, te horoi horoi, nga mea hanga gypsum me te biomedicine.

2.2.2 Ngako waipiro polyoxyethylene ether sulfate
Ko te waipiro polyoxyethylene ether sulfate (AES) he momo surfactant ka riro mai i te waipiro polyoxyethylene ether (ko te nuinga o te 1~3 te EO) na roto i te SO3 sulfation me te whakakore. I tenei wa, ko te hua i runga i te maakete o-whare e rua nga ahua: he whakapiri me te ihirangi o te 70% me te wai me te ihirangi o te 28%.
Ka whakatauritea ki te AS, na te whakaurunga o te roopu EO i roto i te ngota ngota ka tino pai ake te AES i runga i te aukati ki te wai pakeke me te riri. He pai te whakakorenga a te AES, te whakaemulsification, te makuku me te hukahuka, a he ngawari te koiora. Ka whakamahia nuitia ki te horoi whare me te tiaki whaiaro. He iti te kiri o te tote haukinia AES, ka whakamahia te nuinga ki etahi shampoos teitei me te horoi tinana.

2.2.3 Ngako waipiro polyoxypropylene polyoxyethylene ether sulfate
Ko te polyoxypropylene polyoxyethylene ether sulfate te waipiro ngako, e mohiotia ana ko Extended acid salt surfactant, he momo surfactant kua rangahaua ki tawahi neke atu i te tekau tau. E tohu ana te surfactant toroa ki tetahi momo surfactant e whakauru ana i nga roopu PO, PO-EO ranei i waenga i te mekameka hiku hydrophobic me te roopu upoko hydrophilic o te surfactant katote. Ko te ariā o te "Whakaroa" na Venezuelan Dr. Salager i whakatakoto i te tau 1995. Ko te whai ki te whakawhānui i te mekameka hydrophobic o surfactants, na reira ka whakarei ake i te taunekeneke o te surfactants ki te hinu me te wai. Ko nga ahuatanga o tenei momo surfactant e whai ake nei: tino kaha te kaha o te whakarewatanga, te tino iti-iti te awangawanga atanga me nga momo hinu (<10-2mn>
