E213 / Preservatives
Calcium benzoate
Safety in brief
Safe
Recorded EatMatrix rating, not a new clinical review. The amount, your sensitivities and country rules still matter.
- Watch for
- Recorded sensitivities: benzoate sensitivity.
- Our advice
- Read the whole food label and consider how often you eat the product. A name or E number does not tell you the amount, and an ingredient rating cannot assess the entire food.
What it is
Calcium benzoate is the calcium salt of benzoic acid, used as a preservative in food and beverages such as sauces, dressings, canned goods, and drinks to inhibit bacteria, yeast, and mould growth. It is generally recognized as safe when used within regulated limits and is also used in some cosmetics to prevent microbial contamination.

How to read study types- Regulator reviewEFSA re-evaluation of benzoic acid and benzoates
Set a safe daily limit of 5 mg per kg of body weight and found no DNA or cancer concern. Toddlers and children who often drink flavoured drinks could go over it.
Summaries of each source's published abstract or statement, checked . This is a selection of sources, not a complete literature review. Authority assessments apply to the uses and places they cover.
Health notes from our ingredient record
- Shares the benzene-formation risk of other benzoates when combined with ascorbic acid (vitamin C) under heat, light, or metal-ion exposure; industry mitigations apply.
- Occasional intolerance or mild allergic-type reactions reported in sensitive individuals, consistent with other benzoate salts.

Country rules
Country checks for E213
Permission depends on the market, type of food, amount and conditions. A scientific opinion or an E-number alone does not establish a legal use. These checks are separate from the stored EatMatrix rating.

| European Union | Regulation (EC) 1333/2008, Annex II Part B, version , contains the exact code E213: Calcium benzoate. The footnote addresses presence in certain fermented products resulting from fermentation following good manufacturing practice; that is not an unrestricted added-use permission. Listing alone does not allow every food use. Part E food categories, limits, specifications and applicable later acts still need a product-specific check. Source read: . |
