E217 / Preservatives
Sodium propyl p-hydroxybenzoate
Safety in brief
Better avoided
Recorded EatMatrix rating, not a new clinical review. The amount, your sensitivities and country rules still matter.
- Watch for
- Recorded sensitivities: paraben 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
Sodium propyl p-hydroxybenzoate (sodium propylparaben) is the sodium salt of propylparaben, used as an antimicrobial preservative. It is permitted with limits in several jurisdictions (e.g., US, Canada, Australia/New Zealand, Japan), but it is not authorised as a food additive in the EU/UK following EFSA/JECFA evaluations that excluded propylparaben from the general parabens group acceptable daily intake.

Research & body effects
Health notes from our ingredient record
- Excluded from the JECFA group ADI due to adverse effects observed in male rats; no acceptable daily intake has been established specifically for propylparaben.
- Potential weak endocrine (hormone-mimicking) activity reported in some laboratory studies; human relevance at food-use levels is uncertain.
- Rare hypersensitivity (e.g., contact dermatitis) reported to parabens.
Country rules
Country checks for E217
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.
Compare all eight markets and their sources
| Market | What is checked |
|---|---|
| European Union | No exact code match in the Annex II Part B list (version 2026-08-18, read 2026-10-07). Identity, subform and legal-use review are pending. This does not establish a permission or a ban. |
| Great Britain | No verified exact register record in this review. Identity and current use rules need checking; missing a record does not establish a ban. |
| United States | Complete current-use review pending. Any scoped provision in the label guide above applies only to the stated use. FDA explains the applicable food-additive and GRAS framework. |
| Northern Ireland | Review pending. Check the applicable EU rules and territory arrangements; the GB register alone does not establish this status. FSA guidance is a starting source, not a verified permission for this entry. |
