    • Food and beverages (to prevent spoilage by bacteria and fungi)
    • Medications (creams, ointments, some liquid medications)
    • Cosmetics (lotions, shampoos)

How it works:

  • It works by inhibiting the growth of microorganisms that can cause spoilage or contamination.

Limited Medical Use:

  • While not a primary treatment itself, calcium benzoate might be a supportive ingredient in some topical medications due to its antifungal properties.
  • For example, it could be present in creams to help prevent fungal skin infections.

Safety:

  • Generally recognized as safe (GRAS) by the US Food and Drug Administration (FDA) for use in specific amounts as a food additive [1].
  • Considered safe for most people when used in typical concentrations within medications and cosmetics.

Important Points:

  • High doses of calcium benzoate might cause mild digestive issues like stomach upset in some individuals.
  • In rare cases, people with a sensitivity to benzoic acid (a related compound) might experience allergic reactions.
