Regulatory status

USARestricted

Affirmed as GRAS as an antimicrobial and flavoring agent under 21 CFR 184.1733, with current use resulting in a maximum level of 0.1 percent in food. Source (2026-07-23)

EURestricted

Approved in the EU as E 211 for specified food categories (e.g., beverages, fish products, condiments) with maximum levels set out in Annex II to Regulation (EC) No 1333/2008; EFSA has separately noted that sodium benzoate can react with ascorbic acid (vitamin C) under heat or light to form trace benzene, but this is a formulation/handling concern rather than a change to the additive's authorized status.
