Sodium benzoate is a common ingredient found in many cosmetic and personal care products, primarily valued for its effectiveness as a preservative. Its inclusion helps to prevent microbial contamination, thereby extending the shelf life and maintaining the integrity of formulations like lotions, shampoos, and creams.

The preservative action of sodium benzoate is most potent in products with a lower pH (acidic conditions), where it is converted into its active form, benzoic acid. This property makes it suitable for a wide range of water-based cosmetic products. Its compatibility with other preservatives also allows for synergistic effects, enhancing the overall preservation system.

When considering the safety of sodium benzoate in cosmetic applications, regulatory bodies like the FDA and the EU Cosmetics Regulation have established permissible usage levels. Generally, at concentrations typically used in cosmetics (often between 0.5% to 1.0%), sodium benzoate is considered safe for most consumers. However, as with many cosmetic ingredients, some individuals may experience skin sensitivity or allergic reactions. Brands are encouraged to conduct appropriate safety and patch testing to ensure product suitability for a diverse consumer base.
