PROPYLPARABEN
Commonly Found In
Overview
Propylparaben is a cosmetic preservative in the paraben family, valued for its strong antifungal activity. The EU restricts it to a maximum of 0.14% in leave-on products and prohibits use in products applied to the diaper area for children under 3 (Regulation 358/2014). Studies suggest greater estrogenic potency compared to shorter-chain parabens, which informed the stricter EU limits.
Also known as: propyl p-hydroxybenzoate, propyl 4-hydroxybenzoate, E216, Nipasol M, Tegosept P
Key Benefits
Acts as a preservative; no direct skin-conditioning benefit. Studies suggest stronger antifungal efficacy than methylparaben at the same concentration.
Supporting Research
- β’ EU Regulation 358/2014: Restricted propylparaben to 0.14% in leave-on cosmetics and banned in diaper-area products for children under 3 based on endocrine disruption assessment
- β’ SCCS/1348/10 (2011): Reviewed endocrine-disruption potential; stricter limits applied relative to shorter-chain parabens

Overview of current status across major international markets.
Detailed Regional Status
| Region | Status | Max Conc. | Conditions | Source |
|---|---|---|---|---|
| πͺπΊ EU | Allowed | - | - | Official β |

π Why Regulations Differ
EU tightened limits on propyl- and butylparaben in 2014 (Regulation 358/2014) due to endocrine disruption concerns, particularly for vulnerable populations (infants). Japan and US have not adopted similar restrictions at typical cosmetic-use concentrations.
Recent Regulatory Changes
- β’ EU Regulation 358/2014 (April 2014): Reduced leave-on limit to 0.14% and banned in diaper-area products for children under 3

Category Comparison
There are 219 ingredients in the PERFUMING category. 100% are banned in at least one major market.
Strictness Ranking
πΏ Natural Sources
Occurs naturally in trace amounts in some plants and their metabolites, but commercial propylparaben is exclusively synthetic.
π How It's Made
Produced by esterification of p-hydroxybenzoic acid with propanol (n-propanol) using an acid catalyst. The process yields propyl p-hydroxybenzoate through Fischer esterification.
π Uses in Cosmetics
Used at 0.1-0.4% as a preservative with stronger antifungal activity than methylparaben. EU restricts to max 0.14% (as acid) in leave-on products, banned in diaper area products for children under 3 (Regulation 358/2014, April 2014). Effective against yeasts, molds, and some bacteria.
π¬ Other Applications
Used as a food preservative (E216 for propylparaben, E217 for sodium propylparaben) in some countries, though usage is decreasing. Also found in pharmaceuticals.
π‘ Fun Facts
- β’ EU's 2014 restriction followed studies suggesting propylparaben may have weak endocrine-disrupting effects at high concentrations
- β’ Propylparaben has a longer alkyl chain than ethylparaben, making it more lipophilic and thus more effective against fungi but also more hormonally active
- β’ Japan still allows propylparaben at 1.0% concentration, while the EU has reduced limits to 0.14% for leave-on products
