    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.
