What is Sodium Benzoate (Cosmetic)?
Sodium benzoate is the sodium salt of benzoic acid, used as a broad-spectrum antimicrobial preservative in cosmetics, personal care products, and food. In cosmetics it is most effective at acidic pH (<5.5), where it converts to the active benzoic acid form.
Why is Sodium Benzoate (Cosmetic) used in personal-care products?
Used to prevent yeast, mold, and bacterial growth in water-based cosmetic formulations. Often combined with potassium sorbate for broader spectrum coverage. It is considered a relatively safe, low-toxicity preservative.
Is Sodium Benzoate (Cosmetic) dangerous? Documented risks
Sodium benzoate is considered safe for cosmetic use by the CIR and EU SCCS at regulated concentrations (≤2.5% in EU cosmetics). It is a weak sensitizer and can cause urticaria (hives) in some sensitive individuals. At low cosmetic concentrations, systemic risk is negligible — it is rapidly metabolized and excreted. The concern about sodium benzoate + ascorbic acid forming benzene is food-specific and not relevant to most cosmetic applications.

How to avoid Sodium Benzoate (Cosmetic): safer alternatives
Potassium sorbate as a similarly mild preservative; sodium dehydroacetate for antifungal activity.
Frequently asked questions about Sodium Benzoate (Cosmetic)
Is sodium benzoate in cosmetics the same as in food?
Yes, same chemical compound. In cosmetics it is used as a preservative, as in food (E211). Both applications are regulated and considered safe at approved levels.
Does sodium benzoate form benzene in skincare?
The benzene-forming reaction requires sodium benzoate + ascorbic acid + heat/UV, which can occur in some beverages. In most cosmetic products (particularly those without high vitamin C levels), this is not a practical concern.
