Benzoic Acid
Ingredient Info
Benzoic acid is a naturally occurring preservative commonly used in skincare products to prevent bacterial and fungal growth, extending shelf life. It's a weak organic acid found in many plants and is also produced synthetically for cosmetic use.
Benefits
- Antimicrobial preservative that prevents bacterial and fungal contamination
- Helps extend product shelf life and maintain stability
- Naturally occurring compound also found in some foods
Potential concerns
- May cause skin irritation or sensitivity in some individuals, particularly on sensitive or compromised skin
- Can be a contact allergen for people with fragrance or preservative sensitivities
- Typical exposure is generally recognized as safe, but widespread use means cumulative exposure across multiple products
Science: Benzoic acid and its derivatives are widely used as preservatives in food, cosmetics, and pharmaceuticals with established safety profiles at typical concentrations. Limited peer-reviewed data specifically addressing dermal safety in skincare formulations; most safety data derives from food additive studies and general preservative toxicology rather than cosmetic-specific clinical trials.
