Ingredient review
Ethylene/VA Copolymer
INCI: ETHYLENE/VA COPOLYMER
A safe, synthetic film-former that helps makeup and sunscreen stay put without clogging pores.
In plain English
Ethylene/VA Copolymer is a plastic-like ingredient that forms a thin, flexible film on skin or hair. It's often used in waterproof mascaras and long-wear lipsticks to help them resist smudging and water. Think of it as a clear, invisible shield that keeps your makeup in place without feeling heavy or sticky.

Quick decision guide
Useful, but context matters
Ethylene/VA 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 Ethylene/VA 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 ethylene and vinyl acetate monomers, creating a flexible, water-resistant film.
How it works
When applied, the copolymer dries into a continuous, flexible film that adheres to the skin or hair surface. This film helps other ingredients stay put, improves water resistance, and can also thicken a product's texture for easier application.
Pros
Long-lasting wear
Creates a flexible film that helps makeup and sunscreen resist smudging, water, and sweat throughout the day.
Non-comedogenic
Does not clog pores, making it suitable for acne-prone skin when used in appropriate formulations.
Cons and cautions
Removal difficulty
Requires an oil-based or dual-phase makeup remover to fully dissolve the film, which can be inconvenient.
Synthetic origin
Derived from petrochemicals, which may not appeal to those seeking natural or sustainable beauty products.
Best for
- Anyone wanting long-wearing makeup or water-resistant sunscreen
- People with oily skin who need products that stay put
Use caution if
- Those who prefer completely natural or plastic-free formulations
- Individuals with very dry or sensitive skin who may find film-formers too occlusive
Usage tips
Safety summary
Ethylene/VA Copolymer is considered safe for use in cosmetics at typical concentrations. It has low irritation and comedogenic potential, and no significant systemic toxicity concerns have been identified in available research.
Research notes
The Cosmetic Ingredient Review (CIR) panel reviewed data on ethylene/VA copolymer and related polymers, concluding they are safe in current use patterns. No peer-reviewed studies indicate significant health risks from topical application.
Common label clues
- Typical concentration
- Typically 1–10% in leave-on products
- Regulatory status
- Approved for use in cosmetics by the FDA and the European Commission. The Cosmetic Ingredient Review (CIR) panel has deemed it safe as used.
- Common uses
- Mascara, Eyeliners, Lipsticks, Sunscreens, Hair styling products
- Environmental note
- As a synthetic polymer, it is not biodegradable and may contribute to microplastic pollution if not properly filtered during wastewater treatment.
Good to know
- Ethylene/VA Copolymer is different from vinyl acetate alone, which has raised some safety concerns in the past; the copolymer form is considered safe.
- It is often combined with other film-formers to fine-tune flexibility and water resistance.
