Ingredient review
Ethylhexyl Acrylate
INCI: Ethylhexyl Acrylate
Ethylhexyl Acrylate helps makeup and sunscreen last longer, but it can be a mild irritant for sensitive skin.
In plain English
Ethylhexyl Acrylate is a synthetic ingredient that forms a thin, flexible film on your skin. This film helps other ingredients—like sunscreen filters or pigments—stay put longer, even when you sweat or get wet. It's commonly found in long-wear foundations, water-resistant sunscreens, and nail polishes. While generally safe, it can cause mild irritation for people with very sensitive or compromised skin.

Quick decision guide
Useful, but context matters
Ethylhexyl Acrylate can be useful, but watch for some irritation potential.
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 Ethylhexyl Acrylate.
- 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
moderateCan bother some users, especially with frequent use, damaged skin, or strong companion ingredients.
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
Ethylhexyl Acrylate is a synthetic polymer ingredient derived from acrylic acid. It is used in cosmetics primarily as a film-forming agent, meaning it creates a continuous layer on the skin or nails to improve product durability and water resistance.
How it works
When applied, Ethylhexyl Acrylate molecules link together to form a flexible, invisible film on the skin's surface. This film acts as a barrier that locks in other ingredients and prevents them from being easily washed or rubbed off. It also helps distribute pigments evenly and reduces transfer in makeup products.
Pros
Boosts product longevity
Creates a flexible film that helps makeup and sunscreen resist sweat, water, and rubbing, so you need fewer touch-ups.
Improves texture and feel
Helps distribute pigments evenly and gives a smooth, non-sticky finish to foundations and sunscreens.
Cons and cautions
May irritate sensitive skin
Some people with reactive skin or conditions like eczema may experience mild stinging or redness when using products with this ingredient.
Not biodegradable
As a synthetic polymer, Ethylhexyl Acrylate is not readily biodegradable, which may be a concern for environmentally conscious consumers.
Best for
- People who want long-wearing makeup or water-resistant sunscreen
- Those with normal to oily skin who prefer products that stay put
Use caution if
- Individuals with very sensitive or eczema-prone skin who may react to film-forming polymers
Usage tips
Safety summary
Ethylhexyl Acrylate is considered safe for use in cosmetics at typical concentrations. It may cause mild irritation in sensitive individuals, but serious allergic reactions are rare. Regulatory bodies globally permit its use with no specific restrictions beyond general cosmetic safety requirements.
Research notes
Research on Ethylhexyl Acrylate focuses on its film-forming properties and safety profile. The Cosmetic Ingredient Review has assessed similar acrylate copolymers and found them safe. No significant human health risks have been identified from topical cosmetic use.
Common label clues
- Typical concentration
- Typically 0.5–5% in leave-on products
- Regulatory status
- Approved for use in cosmetics in the EU, US, and many other regions. The Cosmetic Ingredient Review (CIR) panel has reviewed related acrylate polymers and found them safe at typical use concentrations.
- Common uses
- Long-wear makeup, Water-resistant sunscreens, Nail polishes
- Environmental note
- As a synthetic polymer, Ethylhexyl Acrylate is not readily biodegradable. Its environmental impact is still being studied, but it is not known to bioaccumulate significantly.
Good to know
- Ethylhexyl Acrylate is often used in combination with other acrylate polymers to fine-tune the flexibility and water resistance of the final product.
- It is not the same as Ethylhexylglycerin (a preservative booster) or Ethylhexyl Methoxycinnamate (a sunscreen filter).
