Cationic surfactants contain positively charged functional groups at their head:

Cationic surfactant

These surfactants consist of  primary, secondary, or tertiary amines, that become a positive charge at pH levels below 10. Neutralisation can take place with acids like hydrochloric or hydrobromic acid.

In case of wax emulsions, acetate counterions are fairly common, like for example in Stearylamine Acetate:
