  • Electrolytes and anionic emulsifier

    Hi!

    I learn that electrolytes reduce the electrical double bond of the dispersed phase particles.

    Hence, electrolytes don’t work with anionic emulsifiers that adsorb anions to keep the particles electrostatically away.

    However, I see this formulation from the good brand Paula’s Choice.

    Water Infusing Electrolyte Moisturizer

    What’s the science of mixing stearic acid (anionic emulsifier) and many electrolytes in the formulation harmoniously - both seem to have high enough concentrations?

    Thank you!
