Is Sodium Benzoate Safe in Makeup?

Yes, sodium benzoate is generally safe in makeup when used within regulatory limits.

Sodium benzoate is a synthetic preservative that prevents harmful bacteria and mold growth in cosmetics. It's widely approved by the FDA and EU for cosmetic use, appearing in 78+ products tracked on beauty sites. The ingredient works by creating an acidic environment that microorganisms can't survive in.

The EU classifies sodium benzoate with a "V/1" restriction, meaning it's permitted but with specific concentration limits to ensure safety. Most cosmetic formulations use it at 0.1-0.5%, well below the maximum allowed 2.5%.

Who should avoid it: People with known sensitivities to benzoates may experience mild irritation, though allergic reactions are uncommon.

When combined with vitamin C in acidic formulations, sodium benzoate can theoretically form benzene (a carcinogen), but this typically requires extreme conditions not found in normal cosmetic use.
