Ingredient review
DMAPA Acrylates Copolymer
INCI: DMAPA ACRYLATES/ACRYLIC ACID/ACRYLONITROGENS COPOLYMER
A synthetic polymer that helps products stay put and resist water, but offers no active skincare benefit.
In plain English
This is a man-made ingredient that forms a thin, flexible film on your skin or hair. Think of it like a clear, invisible coat that helps makeup last longer, keeps hair in place, or makes sunscreen stay on better when you sweat or swim. It doesn't moisturize or treat your skin—it's purely a helper ingredient for texture and durability.

Quick decision guide
Useful, but context matters
DMAPA Acrylates 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 DMAPA Acrylates 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 synthetic copolymer made from DMAPA (dimethylaminopropylamine), acrylic acid, and acrylonitrogens. It is engineered to create a flexible, water-resistant film when applied to skin or hair.
How it works
When the water or solvent in a product evaporates, this polymer leaves behind a thin, continuous film. This film physically locks in other ingredients, resists wash-off by water, and helps maintain the product's original look or hold for hours.
Pros
Long-lasting wear
Helps makeup and sunscreen stay put for hours, even in humid or wet conditions.
Flexible film
The film it forms is flexible, so it won't crack or flake off during movement.
Cons and cautions
No active benefit
It's purely a texture and durability aid—it won't hydrate, soothe, or treat your skin.
Potential buildup
Daily use without thorough cleansing can leave a residue on skin or hair, which may feel heavy or dull.
Best for
- People who want long-wearing makeup or water-resistant sunscreen
- Those who need strong hold in hair styling products
Use caution if
- Anyone with very dry or sensitive skin who prefers minimal film-formers
- People who dislike using double-cleansing to remove water-resistant products
Usage tips
Safety summary
Generally recognized as safe for topical cosmetic use at typical concentrations. Low irritation and comedogenic risk. No known significant health concerns from normal use.
Research notes
Safety assessments by the Cosmetic Ingredient Review (CIR) panel have concluded that similar acrylate copolymers are safe in cosmetics. No peer-reviewed studies specifically on this exact copolymer were found, but the class is well-studied.
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 Cosmetic Ingredient Review (CIR) panel has reviewed similar acrylate copolymers and found them safe at typical use levels.
- Common uses
- Hair styling products, Water-resistant sunscreens, Long-wear makeup, Mascara
- Environmental note
- As a synthetic polymer, it may not be biodegradable. However, it is used in very small amounts per product, and its environmental impact is considered low compared to larger microplastic particles.
Good to know
- This ingredient is often listed near the end of an ingredient list because it's used in small amounts.
- It is not the same as DMAPA itself, which is a raw material; the polymer is fully reacted and considered safe.
