Ingredient review
Acrylate Copolymer Film
INCI: POLY[OXYMETHYLENE MELAMINE ACRYLATES/ACRYLAMIDE]
A synthetic film-former that helps products stay put longer, but offers no active skincare benefit.
In plain English
This is a man-made polymer that dries down to form a thin, invisible film on your skin or hair. Think of it like a very lightweight, breathable plastic wrap that helps makeup last longer or keeps sunscreen from washing off. It doesn't moisturize or treat your skin—it's purely a texture and performance helper.

Quick decision guide
Useful, but context matters
Acrylate Copolymer Film 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 Acrylate Copolymer Film.
- 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 created by combining melamine, formaldehyde, acrylates, and acrylamide. It is designed to form a flexible, water-resistant film when applied to skin or hair.
How it works
When the product dries, the polymer molecules link together into a continuous film. This film acts as a physical barrier that resists water, sweat, and friction, helping the product stay in place longer.
Pros
Boosts wear time
Creates a flexible film that helps makeup and sunscreen resist sweat, water, and rubbing, so you don't have to reapply as often.
Improves sunscreen efficacy
By forming a water-resistant layer, it helps sunscreen stay on the skin longer during swimming or sweating, maintaining SPF protection.
Cons and cautions
Can feel tight
The film can create a slight tightening sensation on the skin, which may be uncomfortable for those with dry or sensitive skin.
Requires double cleansing
Because it's water-resistant, a simple water rinse won't remove it. You'll likely need an oil-based cleanser or micellar water to break it down.
Best for
- People who want long-lasting makeup
- Those using water-resistant sunscreens
- Anyone with normal to oily skin
Use caution if
- People with very dry or dehydrated skin (may feel tight)
- Those who prefer minimal, simple ingredient lists
Usage tips
Safety summary
Generally considered safe for topical use at typical concentrations. Low irritation and comedogenic risk. However, the ingredient contains trace monomers (formaldehyde, acrylamide) that are strictly controlled to very low levels in the final product. Regulatory bodies like the EU CosIng database list it as safe when used as intended.
Research notes
Limited peer-reviewed studies specific to this exact copolymer. Evidence is based on general safety data for similar acrylate copolymers and regulatory reviews. The Cosmetic Ingredient Review (CIR) panel has evaluated related acrylate polymers and found them safe for cosmetic use.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics in the US, EU, and many other regions. Concentrations are typically low and considered safe for topical use.
- Common uses
- Sunscreens, Long-wear makeup, Hair styling products, Water-resistant formulas
- Environmental note
- As a synthetic polymer, it may not be biodegradable. Some environmental concerns exist regarding accumulation in waterways, but specific data on this copolymer is limited.
Good to know
- This ingredient is not a moisturizer or active—it's purely a performance enhancer.
- It is often used in combination with other film-formers for a stronger water-resistant effect.
