What is the ionic charge of Parabens like methyl Paraben?
What is the ionic charge of Parabens?
Are they compatible with cationic surfactants?
Ulprospector says Paraben is incompatible with most of cationic and non-ionic surfactants, cellulose esters, PEG and gelatins.

None to partially negative, depends
.Incompatibility has nothing to do with ‘ionic charge’. -
@Pharma anionics like sodium benzoate doesn’t work well with cationic surfactants like SPDMA. Will it be the same for methyl Paraben at pH 4-5?
How “Incompatibility has nothing to do with ‘ionic charge’.”?

The incompatibility of parabens has something to do with overall structure (especially the aromatic part) and is a thing of observation because there is no clear scientific explanation why and how.Ionic interactions like benzoate with cationic emulsifiers clearly depend on the charge.
