Raws li lawv cov thawj surfactants, lub cev ntxuav tau muab faib ua peb hom hauv qab no:
1. Fatty Acid ntsev-Raws lub cev ntxuav
Kuj feem ntau hu ua "soap-raws li", cov khoom no yog tsim los ntawm neutralizing fatty acids nrog alkali. Lawv muab lub zog ntxuav kom huv, huv huv - ntxuav lub cev, thiab ntau lub lather. Txawm li cas los xij, raws li lawv cov pH yog alkaline-thaum tib neeg cov tawv nqaij ib txwm muaj acidic pH- siv xab npum-raws li lub cev ntxuav tuaj yeem ua rau qee qhov kev khaus khaus ntawm daim tawv nqaij.
2. Synthetic Surfactant-Raws Lub Cev Ntxuav
Cov khoom no feem ntau yog tsim los siv hluavtaws surfactants-xws li cov pom nyob rau hauv amino acid-raws li lub cev ntxuav. Lawv muab cov txiaj ntsig zoo ntawm qhov tsis tshua muaj khaus, zoo thiab muag heev lather, thiab moisturizing xav tom qab ntxuav.
3. Compound-Tom Lub Cev Ntxuav
Cov tshuaj ntxuav lub cev no ua ke ob qho tib si fatty acid ntsev thiab hluavtaws surfactants. Los ntawm kev ua li ntawd, lawv siv lub zog ntxuav tau zoo thiab nplua nuj lathering cov khoom ntawm fatty acid ntsev thaum tib lub sij hawm sib xyaw ua ke ntawm qhov sib sib zog nqus thiab qis - cov txiaj ntsig ua rau khaus ntawm cov khoom siv hluavtaws.
