Ingredient review
Aminoethylpropanediol-AMPD-Acrylates Copolymer
INCI: AMINOETHYLPROPANEDIOL-AMPD-ACRYLATES/DIACETONEACRYLAMIDE COPOLYMER
A synthetic polymer that helps products stay put, but offers no active skincare benefit.
In plain English
This is a synthetic ingredient that forms a thin, flexible film on your skin. It helps makeup or sunscreen stay in place longer and resist water or sweat. Think of it like a clear, invisible shield that holds the product where you put it. It doesn't moisturize or treat your skin—it's purely a helper ingredient for texture and wear.
Quick decision guide
Useful, but context matters
Aminoethylpropanediol-AMPD-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 Aminoethylpropanediol-AMPD-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 high-molecular-weight synthetic copolymer created by combining aminoethylpropanediol, AMPD, acrylates, and diacetoneacrylamide. It belongs to a class of film-forming polymers widely used in cosmetics.
How it works
When applied, the polymer chains spread into a thin, even layer. As the solvent (usually water or alcohol) evaporates, the chains link together into a continuous film. This film physically locks in pigments or UV filters and resists removal by water or friction.
Pros
Boosts wear time
Creates a durable film that helps makeup and sunscreen resist sweat, water, and rubbing, so you don't have to reapply as often.
Improves texture
Helps products spread evenly and dry down to a smooth, non-tacky finish, which can make application easier.
Cons and cautions
Can feel tight
The film may cause a slight stiff or tight sensation on the skin, especially if you have dry skin or use a high concentration.
No active benefit
It doesn't hydrate, soothe, or treat the skin—it's purely a functional ingredient for product performance.
Best for
- Anyone wanting long-wearing or waterproof makeup
- People who use water-resistant sunscreens for outdoor activities
Use caution if
- Those who prefer lightweight, breathable formulas and dislike a film-like feel
Usage tips
Safety summary
Considered safe for cosmetic use at typical concentrations. Low irritation and comedogenic risk. No known significant safety concerns based on current evidence.
Research notes
Limited peer-reviewed studies specific to this exact copolymer, but film-forming acrylate polymers as a class have a long history of safe use in cosmetics. Safety assessments rely on analogy to similar polymers.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics in the US, EU, and other major markets. No specific restrictions at typical use levels.
- Common uses
- Sunscreens, Waterproof makeup, Long-wear foundations, Setting sprays
- Environmental note
- As a synthetic polymer, it is not biodegradable. However, it is used in small amounts and is removed during wastewater treatment.
Good to know
- This polymer is often used in combination with other film-formers to fine-tune the feel and durability.
- It is not absorbed into the skin—it stays on the surface and is removed with cleansing.
