Surfactants muaj ib pab pawg hydrophobic ntawm ib kawg thiab ib pawg hydrophilic ntawm lwm yam. Surfactants muaj cov haujlwm xws li tshem tawm cov av, thickening, foaming, thiab ntub dej. Tam sim no, lub ntiaj teb txhua xyoo tsim cov surfactants tau mus txog 16 lab tons, thiab cov surfactants no feem ntau siv raw cov ntaub ntawv hauv tshuaj pleev ib ce. Surfactants muaj peb yam tseem ceeb: detergency, uas yog siv nyob rau hauv zus tau tej cov cleansing tshuaj pleev ib ce; emulsification, uas yog siv los ua emulsifier hauv kev tsim cov tshuaj pleev thiab tshuaj zawv plaub hau; thiab ntub dej thiab nkag mus rau hauv cov khoom, xws li muaj peev xwm sib cuag cov plaub hau dyes thiab perms nrog daim tawv nqaij, thiab muaj peev xwm kis tau rau hauv lub ntsej muag cream thiab lipsticks.
Nonionic surfactants yog surfactants uas tsis dissociate rau ions hauv dej. Hauv cov tshuaj pleev ib ce, muaj ntau ntau yam, thiab ntau npaum li cas siv yog loj heev. Lub ntsiab ntau yam yog muab faib ua ob pawg: polyoxyethylene hom thiab polyol hom. Polyoxyethylene hom muaj xws li polyoxyethylene fatty cawv ether, polyoxyethylene alkylphenol ether, polyoxyethylene fatty acid ester, polyoxyethylene fatty amide, thiab lwm yam. polyol hom muaj xws li alkylolamide, sorbitan monostearate, thiab lwm yam hauv cov tshuaj pleev ib ce, emulsifiers, foaming agents, thickeners thiab dispersants feem ntau siv nonionic surfactants.
