Although sodium benzoate is considered safe for consumption in regulated amounts, there are some health concerns associated with its use, particularly when it is combined with ascorbic acid (vitamin C) in products, such as soft drinks. Under certain conditions, this combination can produce benzene, a known carcinogen. However, regulatory agencies, including the FDA and the European Food Safety Authority, have set stringent limits on the concentrations used in food products to mitigate such risks.

The use of sodium benzoate in cosmetics is strictly regulated. Agencies such as the FDA (Food and Drug Administration) in the United States and the European Commission's Scientific Committee on Consumer Safety (SCCS) have evaluated its safety. These evaluations conclude that sodium benzoate is safe for use in cosmetics when used within recommended concentrations — generally up to 1.0%. However, it is essential to note that while sodium benzoate is considered safe, it can react with certain other components, such as ascorbic acid (vitamin C), to form benzene, a known carcinogen. This potential reaction emphasizes the importance of formulation balance and careful ingredient selection in cosmetic production.
