Acts a preservative. Sodium Benzoate is the inactive salt of benzoic acid. As benzoic acid, it is considered to be primarily an anti-fungal, but it shows some activity against bacteria. It is not the most effective against pseudomonads. Benzoic acid is inactivated by non-ionics and by raising the pH.
Sodium Benzoate is not a broad spectrum preservative for cosmetic use and should be combined with other preservatives. If Sodium Benzoate is used as a preservative, the pH of the finished product may need to be lowered enough to release the free acid for useful activity. Sodium Benzoate is often combined with Potassium Sorbate in low pH products to provide a synergistic preservative effect against yeast and mould.
