Benzoic acid and sodium benzoate (see section 4.3.2) are used as preservatives in beverages, fruit products, chemically leavened baked goods, and condiments, preferably in a pH range below 4.5. A disadvantage is the off-flavour they may impart to foods (Chipley, 1983).
pH Flexibility: Sodium Benzoate maintains its preservative effectiveness across different pH levels, making it suitable for a wide range of cosmetic products with varying acidity or alkalinity.
