Ingredient review
Acrylates/VA/Vinyl Neodecanoate Copolymer
INCI: ACRYLATES/VA/VINYL NEODECANOATE COPOLYMER
A synthetic film-former that helps products stay put and resist water, but offers no active skincare benefit.
In plain English
This is a synthetic polymer that creates a thin, flexible film on your skin or hair. Think of it like an invisible, breathable plastic wrap that helps makeup or sunscreen stay in place longer and resist sweat or water. It doesn't treat or change your skin—it's purely a texture and performance helper.
Quick decision guide
Useful, but context matters
Acrylates/VA/Vinyl Neodecanoate 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 Acrylates/VA/Vinyl Neodecanoate 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 acrylic acid, vinyl acetate, and vinyl neodecanoate monomers. 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 physically locks in pigments and active ingredients, reduces transfer to clothing, and prevents water from washing the product away. It also helps control the feel of the product, making it less sticky or more spreadable.
Pros
Boosts wear time
Creates a flexible film that helps makeup and sunscreen last through sweat, humidity, and water exposure.
Reduces transfer
Keeps pigments and product on your skin instead of rubbing off onto clothes, masks, or phone screens.
Cons and cautions
Can feel tight
On dry or sensitive skin, the film may create a slight pulling or tightening sensation, especially if layered heavily.
No active benefit
This ingredient is purely a performance enhancer—it doesn't hydrate, soothe, or treat the skin in any way.
Best for
- Anyone wanting long-lasting, water-resistant makeup or sunscreen
- People with oily or combination skin who prefer a matte, stay-put finish
Use caution if
- Those with very dry or sensitive skin who find film-formers uncomfortable or tight
Usage tips
Safety summary
Acrylates/VA/Vinyl Neodecanoate Copolymer is considered safe for cosmetic use at typical concentrations. It has low irritation and comedogenic potential. No significant safety concerns have been raised by regulatory bodies.
Research notes
Safety assessments by the Cosmetic Ingredient Review (CIR) panel have concluded that acrylates copolymers are safe as used in cosmetics. Most evidence comes from industry safety data and regulatory reviews, not independent clinical studies.
Common label clues
- Typical concentration
- 1% to 10%
- Regulatory status
- Approved for use in cosmetics globally, including by the U.S. FDA and EU CosIng database, with no concentration restrictions.
- Common uses
- Sunscreens, Waterproof makeup, Long-wear foundations, Mascaras, Setting sprays
- Environmental note
- As a synthetic polymer, it is not biodegradable and may contribute to microplastic concerns if washed into waterways. However, it is used in small amounts and is not classified as a primary microplastic in most regulations.
Good to know
- This polymer is often used in 'waterproof' and 'long-wear' formulas, so it may require double cleansing to remove completely.
- It is considered safe and non-irritating at typical use levels by cosmetic safety panels.
