    Hello @Chemist_Ahmed, I would recommend the Optiphen ND (AKA Rokonsal ND) it is a great broadspectrum preservative system and can be used at low concentrations (0.2%) for surfactant systems.

    Parabens and to make your life easier go for the sodium salts of parabens, this will make them easily soluble in water.
