METHYLPARABEN
Commonly Found In
Overview
Methylparaben is a widely used cosmetic preservative and the most common member of the paraben family. It works by inhibiting bacterial and fungal growth in formulations, and has been used safely in personal care products for over 90 years. It also occurs naturally in small amounts in blueberries and other fruits.
Also known as: methyl p-hydroxybenzoate, methyl 4-hydroxybenzoate, E218, Nipagin M, Tegosept M
Key Benefits
Primarily functions as a preservative to extend product shelf life and prevent microbial contamination; studies suggest it does not provide direct skin benefits but helps maintain the safety and stability of formulations containing beneficial active ingredients.
Supporting Research
- β’ SCCS/1348/10 (2011): SCCS concluded methylparaben is safe for use in cosmetics at concentrations up to 0.4% (single paraben) and 0.8% (mixed parabens); endocrine disruption concerns at cosmetic-use concentrations not substantiated
- β’ Darbre PD et al. (2004): Study detected parabens in breast tissue samples; no causal link to cancer established

π Why Regulations Differ
EU restricts methylparaben to 0.4% (individual) or 0.8% (mixed) under Annex V. Japan permits up to 1%. US has no specific concentration limit but CIR has assessed it as safe. Concerns about endocrine disruption at very high doses have not been substantiated at cosmetic-use levels per SCCS 2011.
Regulation Analysis
Regional Agreement
Banned in UK but allowed in EU, USA, Japan.
Category Comparison
There are 122 ingredients in the FRAGRANCE category. 100% are banned in at least one major market.
Strictness Ranking
πΏ Natural Sources
Found naturally in blueberries, strawberries, and some other fruits as a plant metabolite. However, commercial methylparaben is synthetically produced.
π How It's Made
Synthesized by esterification of p-hydroxybenzoic acid with methanol in the presence of an acid catalyst.
π Uses in Cosmetics
Used at up to 0.4% (individual) or 0.8% (total parabens) as a broad-spectrum preservative against bacteria and fungi. Most commonly used paraben due to its effectiveness and low cost.
π¬ Other Applications
Used as a food preservative (E218), in pharmaceuticals, and in some food packaging materials.
