Tus nonionic surfactants yog cov tshuaj lom tsawg duathiab, raws li qhov xav tau, tsis muaj kev phom sij ntau dua li cov tshuaj anionic. Cationic surfactants: Concentrated (10-15%) cov kev daws teeb meem yog caustic thiab txawm tias dilute (0.1-0.5%) cov kev daws teeb meem ua rau cov mucosal irritation tseem ceeb. Kev noj ntau ntau tuaj yeem ua rau CNS cov tsos mob.
