Parabens in cosmetics: facts, myths and EU rules
Methylparaben, propylparaben, butylparaben – which parabens are still allowed in the EU, under what limits, and what a “paraben-free” label really means.

What parabens are
Parabens are esters of p-hydroxybenzoic acid used as preservatives: they protect water-containing products from bacteria and moulds. On INCI lists they appear as Methylparaben, Ethylparaben, Propylparaben and Butylparaben, sometimes as their sodium salts (for example Sodium Methylparaben).
They have been used for decades because they are effective at low concentrations and work across a range of pH values.
Which parabens the EU allows
In the EU, preservatives may only be used if they are listed in Annex V of Regulation (EC) No 1223/2009. Methylparaben and ethylparaben are allowed with a maximum of 0.4% for a single ester and 0.8% for mixtures of esters (expressed as acid).
Propylparaben and butylparaben are allowed under stricter conditions: their combined concentration is limited to 0.14% (as acid), and they must not be used in leave-on products designed for the nappy area of children under three.
Which parabens are banned
Since 2014–2015, five parabens may no longer be used in cosmetics in the EU: isopropylparaben, isobutylparaben, phenylparaben, benzylparaben and pentylparaben. The European Commission’s scientific committee (SCCS) could not confirm their safety because of insufficient data.
If you see one of these names on a product sold in the EU today, the information may be outdated or the product may not comply with the rules.
Where the controversy came from
Public concern about parabens grew in the 2000s after reports suggesting possible hormone-like activity and studies that detected parabens in tissue. The SCCS has assessed parabens several times; its opinions formed the basis for the limits and bans described above.
Scientific opinions assess specific substances at specific concentrations. That is why methylparaben and butylparaben are treated differently in EU law, even though both are “parabens”.
What “paraben-free” means
A “paraben-free” claim means the product uses a different preservation system, for example Phenoxyethanol, Sodium Benzoate with Potassium Sorbate, Benzyl Alcohol or combinations with ingredients such as Ethylhexylglycerin or Caprylyl Glycol.
Every preservative has its own profile of benefits and potential sensitisation. “Paraben-free” is not automatically gentler or safer – it simply means a different choice. In the EU, claims that denigrate legally permitted ingredients are discouraged by the common criteria for cosmetic claims.
Parabens and allergies
Contact allergy to parabens is considered relatively uncommon on intact skin. People with a diagnosed paraben allergy, usually confirmed by patch testing with a dermatologist, should avoid them – and the INCI list makes that possible because every paraben must be named.
What the label does not tell you
The INCI list shows which paraben is present but not its exact concentration. In the EU, that concentration must stay within legal limits and is part of the product’s safety assessment. If you want to avoid parabens, you can use our list of paraben-free products – but always check the current label, because formulas change.
