Ingredient review
Carboxyethyl Acrylate
INCI: Carboxyethyl Acrylate
Carboxyethyl acrylate is a synthetic polymer that helps create a smooth, even film on skin, improving product texture and water resistance.
In plain English
Carboxyethyl acrylate is a man-made ingredient that forms a thin, flexible film on your skin. This film helps other ingredients stay in place, gives products a silky feel, and can make them more water-resistant. It's commonly used in sunscreens and long-wear makeup to improve performance without feeling heavy or sticky.

Quick decision guide
Useful, but context matters
Carboxyethyl Acrylate 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 Carboxyethyl 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
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
Carboxyethyl acrylate is a synthetic polymer derived from acrylic acid. It is produced through a controlled chemical process and is used in cosmetics primarily as a film former and thickener.
How it works
When applied to the skin, carboxyethyl acrylate molecules link together to form a continuous, flexible film. This film helps lock in other ingredients, reduces water loss from the product, and creates a smooth, even surface for makeup or sunscreen application.
Pros
Improves product performance
Helps sunscreens and makeup stay put longer, even in humid conditions, so you don't have to reapply as often.
Lightweight feel
Creates a smooth, non-greasy film that doesn't clog pores or feel heavy, making it suitable for daily use.
Cons and cautions
Synthetic origin
Not derived from natural sources, which may be a drawback for those seeking plant-based or organic skincare.
Potential tackiness
In high concentrations, it can leave a slightly sticky or tight feeling on the skin, especially if layered with other products.
Best for
- Anyone looking for long-wearing makeup or water-resistant sunscreen
- People with normal to oily skin who prefer a matte finish
Use caution if
- Those with extremely sensitive or reactive skin may want to patch-test first
Usage tips
Safety summary
Carboxyethyl acrylate has a low irritation and comedogenic risk. It is generally well-tolerated, but those with very sensitive skin should patch-test first. No significant safety concerns have been reported in cosmetic use.
Research notes
Research on carboxyethyl acrylate focuses on its film-forming and rheological properties. Studies confirm its safety in topical applications at typical concentrations. It is not associated with systemic toxicity or significant skin sensitization.
Common label clues
- Typical concentration
- 0.1% to 2%
- Regulatory status
- Approved for use in cosmetics in the US (FDA), EU (CosIng), and many other regions. No known restrictions at typical use levels.
- Common uses
- Serums, Moisturizers, Sunscreens, Makeup
- Environmental note
- As a synthetic polymer, it is not biodegradable. However, it is used in very small amounts and is not known to accumulate in the environment.
Good to know
- Carboxyethyl acrylate is often combined with other film-formers to balance texture and flexibility.
- It is considered safe for use in cosmetics by major regulatory bodies at typical concentrations.
