I am looking for a cationic detergent for a project. Unfortunately most ( or all?) cationic detergents are quaternary ammonium that smell like rotten fish or even worse The product I am working on can not have odor. Is there such cationic detergent out there or an odor neutralizer ?

    $\begingroup$ sigh I guess you didn't check your misunderstanding in practice. These are quaternary ammonium salts and only neutral amines not their salts may have bad smell. $\endgroup$ – Mithoron Oct 22 '17 at 12:10
  • $\begingroup$ @Mithoron thank you. That is a good point. What I am looking for is something with foaming capacity and not just disinfectant like most of them. If you know any QA salt that can make foam and bubbles ( like soap ) that would be the answer and I highly appreciate that. $\endgroup$ – Aug Oct 22 '17 at 13:23
