Sodium benzoate is not recommended as a preservative at pH ranges higher than 4.5. The effectiveness of sodium benzoate as a preservative increases with decreasing pH (increasing acidity). This is because the ratio of undissociated (i.e., free) benzoic acid to ionized benzoic acid increases as the pH decreases.
