    Yes some of them do, others don’t. It depends on the specific surfactant and whether it has moieties that like to donate (acids) or take (bases) protons. The manufacturer will normally disclose the pH that surfactant gives at a given dilution. Best to simply use a pH meter and check your formula’s pH.

    I recommend you do some reading on what pH means, and also look at pKa and pKb. 

    You could also take an introductory organic chemistry course if you really want to know and understand why.
