Phenoxyethanol
What it does
Nearly every product that contains water needs a preservative, or it would spoil within weeks. Phenoxyethanol is a broad-spectrum preservative — it protects against bacteria, yeast, and mold — which is why it appears in so many moisturizers, serums, cleansers, and sunscreens. It became especially common as brands moved away from parabens.
What to know
In the EU, phenoxyethanol is regulated under Annex V of the Cosmetics Regulation to a maximum concentration of 1%, and the Cosmetic Ingredient Review (CIR) panel has assessed it as safe as used in cosmetics. At these everyday levels most people tolerate it well. Like many preservatives, it can occasionally cause irritation or sensitivity — most likely on reactive or compromised skin.
Commonly found in
Moisturizers, serums, cleansers, sunscreens, and most other water-based formulas.
Frequently asked questions
Is phenoxyethanol safe?
At the low concentrations allowed in cosmetics, regulators including the EU and the CIR consider it safe as used. Most people use it daily without any issue.
Is phenoxyethanol better than parabens?
It is simply a different preservative. Many brands adopted it as a paraben alternative, but both are considered safe within their regulated limits.
Can phenoxyethanol irritate skin?
Occasionally, and most likely on very sensitive or already-compromised skin. If a product bothers you, its full ingredient list can help you find the likely cause.
