Type of additive (Glossary) | Preservatives |
E Number | E232 |
Chemical Formula | C12H9NaO |
Also Known As | Sodium o-phenylphenol Sodium 2-phenylphenolate Sodium o-phenylphenate |

Purpose and Function
Sodium Orthophenyl Phenol (E232) is used as a preservative, particularly for its antifungal properties. It is not directly added to foods but is applied to the surface of certain fruits to prevent fungal growth and spoilage during storage and transportation. Common uses include:
- Citrus fruits: Applied to the peels of oranges, lemons, and other citrus fruits to prevent mold growth and extend shelf life.
- Food packaging: Sometimes used in food packaging materials to inhibit microbial growth.
Sodium Orthophenyl Phenol (E232) is effective at preventing fungal growth on the surface of treated fruits, especially citrus fruits, but is intended only for the outer layers and not for direct consumption.
Potential Risks and Side Effects
Sodium Orthophenyl Phenol (E232) has several potential risks and safety concerns:
- Toxicity concerns: E232 can be toxic if ingested in significant quantities. It is not intended for consumption, and consumers are advised to wash or peel treated fruits thoroughly to minimize exposure.
- Skin and eye irritation: Handling fruits treated with Sodium Orthophenyl Phenol may cause irritation in sensitive individuals.
- Regulatory restrictions: Due to potential health risks, the use of E232 is tightly regulated, and in some countries, it may be restricted or banned for certain applications. When allowed, it is typically used only for surface treatments where the peel is not meant to be consumed.
These safety concerns mean that Sodium Orthophenyl Phenol (E232) is used with caution, mainly as a surface treatment to control fungal growth on specific types of produce.
