Ingredient review
PEG-10 Acrylate/Perfluorohexyethyl Acrylate Copolymer
INCI: PEG-10 Acrylate/Perfluorohexyethyl Acrylate Copolymer
A synthetic film-former that helps makeup and sunscreen stay put, but its perfluoro component raises environmental questions.
In plain English
This ingredient is a synthetic polymer that forms a thin, flexible film on your skin. It's often used in waterproof and long-wear cosmetics to help them resist water, sweat, and smudging. Think of it like a clear, invisible shield that keeps your makeup in place. The 'perfluoro' part means it contains fluorine atoms, which give it strong water- and oil-repelling properties, but also make it persistent in the environment.

Quick decision guide
Useful, but context matters
PEG-10 Acrylate/Perfluorohexyethyl Acrylate Copolymer is generally a lower-concern ingredient when the full formula suits your skin.
Plain-English read
Treat this as a practical screening step before you compare products that contain this ingredient.
- Step 1Start with the score, then check the irritation and clogging risk before judging PEG-10 Acrylate/Perfluorohexyethyl Acrylate Copolymer.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.
Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
A copolymer made by reacting PEG-10 acrylate with perfluorohexyethyl acrylate. It belongs to a class of fluorinated polymers that create durable, water-resistant films.
How it works
When applied, the polymer chains spread across the skin and link together as the solvent evaporates, forming a continuous, flexible film. This film physically blocks water and oil from disturbing the product underneath, enhancing wear time and water resistance.
Pros
Excellent water resistance
Helps products withstand water, sweat, and humidity, making it ideal for long-wear and waterproof formulations.
Flexible film
The film it forms is flexible, so it moves with your skin without cracking or flaking, improving comfort during wear.
Cons and cautions
Environmental persistence
The perfluoro component is highly stable and does not break down easily in the environment, raising concerns about accumulation.
Synthetic origin
As a synthetic polymer, it may not appeal to those seeking natural or minimal-ingredient routines.
Best for
- People who need long-wearing or waterproof makeup
- Those who want sunscreen that stays effective during swimming or sweating
Use caution if
- Individuals seeking fully biodegradable or eco-conscious products
Usage tips
Safety summary
Generally considered safe for topical use at typical concentrations. Low irritation and comedogenic potential. The main concern is environmental persistence rather than direct human toxicity.
Research notes
Limited peer-reviewed studies specifically on this copolymer. Safety is inferred from similar film-forming polymers and general perfluoroalkyl compound assessments. Regulatory bodies have not flagged it as a human health risk in cosmetics.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics in the US, EU, and many other regions. No specific restrictions beyond general cosmetic safety requirements.
- Common uses
- Waterproof mascara, Long-wear foundation, Sunscreen, Lip products
- Environmental note
- Perfluoroalkyl substances are known to be persistent in the environment. While this specific polymer is large and may not be bioavailable, its degradation products are a concern.
Good to know
- This ingredient is often listed near the end of ingredient lists because it is used at low concentrations.
- It is not a sunscreen active ingredient but is added to sunscreens to improve water resistance.
