What E216 actually is
Propylparaben stops mould and bacteria growing, and it works across a wider pH range than benzoates or sorbates, which is why it suited baked goods and tortillas. It is the same class of compound used as a preservative in cosmetics, which is where most people have heard of parabens.
What it is made from
Synthesised from para-hydroxybenzoic acid and propanol. Para-hydroxybenzoic acid does occur naturally in some plants, but the additive is manufactured.
Vegan, vegetarian, and halal status
Fully synthetic with no animal-derived input, so it suits vegan, vegetarian, halal, and kosher diets. The dietary question is not why this one matters.
Is E216 safe?
This is one of the clearest regulatory splits in food additives, and it is worth understanding rather than picking a side. In 2004 EFSA reviewed the parabens and could not establish an acceptable daily intake for propylparaben, because a rat study reported effects on sperm production and testosterone at doses where no clear no-effect level could be identified. The EU removed it from the permitted food additive list in 2006. The FDA has not followed, and propylparaben remains generally recognized as safe for food use in the United States, where it appears in some baked goods and tortillas. The broader paraben endocrine question has continued in the scientific literature since. Both regulators looked at overlapping evidence and weighed the uncertainty differently. The practical consequence is that the same product category can be formulated differently on either side of the Atlantic.
- Removed from the EU permitted food additive list in 2006 after EFSA could not set an acceptable daily intake
- Still generally recognized as safe for food use in the United States
- The underlying concern is endocrine activity reported in animal studies, not acute toxicity
- Widely used in cosmetics, which is separate from food regulation

Foods it turns up in
- US baked goods and tortillas
- Some US processed foods and fillings
- Cosmetics and personal care products
- Some medicines
Names it hides behind
- E216
- Propylparaben
- Propyl p-hydroxybenzoate
- E217 sodium propyl p-hydroxybenzoate
- Propylparaben on a US ingredient list
Common questions
- Is propylparaben banned?
- In EU and UK food, yes, since 2006. In US food it remains permitted. The split came from EFSA being unable to set a safe intake level while the FDA maintained its position.
- Why did the EU remove it?
- A rat study reported effects on sperm production and testosterone at doses where no clear no-effect level could be identified, so EFSA could not establish an acceptable daily intake.
- Which foods contain propylparaben?
- Mainly US baked goods, tortillas, and some fillings. You will not find it in EU or UK food, because it is not permitted there.
- Is propylparaben vegan and halal?
- Yes. It is synthetic with no animal-derived input.
- Are food parabens the same as cosmetic parabens?
- The same class of compound, regulated separately. The cosmetic paraben debate is a different regulatory conversation from the food one.
Checking a real pack
This page answers the code. The pack in your hand is what decides, because the same code can come from different sources depending on the manufacturer. LabelWise, formerly SafeChoice, scans the label and explains what is in front of you.
LabelWise content is educational and describes how additives are made, regulated, and labelled. It is not medical, dietary, or religious advice. For certification questions, the mark on the pack and the certifying body are the authority.
