Ingredient review
Perfluorohexylethyl Acrylate Crosspolymer
INCI: ACRYLIC ACID/PERFLUOROHEXYLETHYL ACRYLATE CROSSPOLYMER
A synthetic polymer that helps products stay put, especially in water-resistant sunscreens and long-wear makeup.
In plain English
This is a synthetic ingredient that forms a thin, flexible film on your skin. It helps other ingredients stick around longer, resist water and sweat, and gives products a smooth, even feel. Think of it like a gentle, invisible shield that keeps your makeup or sunscreen in place.
Quick decision guide
Useful, but context matters
Perfluorohexylethyl Acrylate Crosspolymer 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 Perfluorohexylethyl Acrylate Crosspolymer.
- 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 crosslinked polymer made from acrylic acid and a perfluorohexylethyl acrylate monomer. It is a high-molecular-weight synthetic compound designed to create a durable, water-resistant film on the skin or hair.
How it works
When applied, the polymer spreads into a thin, continuous film that physically blocks water and oil from washing away other ingredients. It also thickens the product slightly, improving texture and application. The crosslinked structure makes the film flexible rather than stiff or flaky.
Pros
Excellent water resistance
Helps sunscreens and makeup stay effective even when you sweat or swim, reducing the need for frequent reapplication.
Flexible film feel
Unlike some older polymers, this one forms a flexible film that moves with your skin, so it doesn't crack or feel stiff.
Cons and cautions
Synthetic origin
It is a man-made polymer, which may be a turn-off for those seeking a fully natural or minimal-ingredient routine.
Potential tackiness
In high concentrations or on very oily skin, it can leave a slightly sticky or heavy finish that some find uncomfortable.
Best for
- People who need water-resistant sun protection for swimming or sweating
- Anyone wanting long-wear makeup that stays put through the day
Use caution if
- Those who prefer exclusively natural or plant-based ingredients
Usage tips
Safety summary
Generally considered safe for topical cosmetic use at typical concentrations. The high molecular weight prevents significant skin absorption. Some environmental concerns exist due to its fluorinated nature, but regulatory bodies currently approve it for cosmetics.
Research notes
Limited independent studies on this specific polymer, but the broader class of crosslinked acrylate/perfluoroacrylate polymers is well-studied for film-forming and water-resistance properties. Safety assessments rely on the lack of skin penetration and low irritation potential.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics in the US, EU, and many other regions. The EU has specific restrictions on certain PFAS, but this high-molecular-weight polymer is generally exempt due to low absorption risk.
- Common uses
- Sunscreens, Long-wear foundations, Waterproof mascaras, Lip products
- Environmental note
- As a fluorinated polymer, there are ongoing environmental concerns about persistence and bioaccumulation. However, high-molecular-weight versions like this are less likely to enter the environment in a bioavailable form.
Good to know
- This ingredient is part of the PFAS family, though it is a high-molecular-weight polymer that is considered non-bioavailable and safe for topical use by regulators.
- It is commonly found in 'water-resistant' or 'very water-resistant' sunscreens.
