Sodium DVB/Acrylates Copolymer
INCI: SODIUM DVB/ACRYLATES COPOLYMER
A synthetic polymer that helps products stay put and feel smooth, with a low risk of irritation.
In plain English
Sodium DVB/Acrylates Copolymer is a man-made ingredient that forms a thin, flexible film on your skin or hair. This film helps other ingredients stick around longer, so your sunscreen stays effective or your mascara doesn't smudge. It also gives products a silky, even feel when you apply them.

Quick decision guide
Useful, but context matters
Sodium DVB/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 Sodium DVB/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 divinylbenzene (DVB) and acrylate monomers, neutralized with sodium to make it water-dispersible. It is a white powder or liquid dispersion used to create a film on skin or hair.
How it works
When applied, the polymer particles spread out and then coalesce into a continuous, invisible film as the water evaporates. This film acts as a barrier that locks in other ingredients and resists water and sweat, improving wear time and texture.
Pros
Boosts water resistance
Helps sunscreens and makeup stay effective even when you sweat or get wet, so you don't have to reapply as often.
Enhances wear time
Creates a flexible film that keeps foundation, mascara, and lip products from smudging or fading throughout the day.
Cons and cautions
Synthetic origin
Made from petrochemicals, which may be a concern if you prefer natural or plant-based ingredients.
Potential tightness on dry skin
The film can feel slightly stiff or drying on very dry or dehydrated skin, especially in high concentrations.
Best for
- Anyone looking for long-wearing makeup or water-resistant sunscreen
- People with normal to oily skin who want a smooth, matte finish
Use caution if
- Those who strictly avoid synthetic ingredients
- Individuals with very dry or sensitive skin who may find film-formers uncomfortable
Usage tips
Safety summary
Sodium DVB/Acrylates Copolymer has a low irritation and comedogenic risk. It is considered safe for most skin types when used in typical cosmetic concentrations. No significant safety concerns have been reported.
Research notes
Research on this specific polymer is limited, but studies on similar acrylate copolymers show they are well-tolerated on skin and effective as film-formers. Regulatory reviews support its safety in cosmetics.
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 evaluated similar acrylate copolymers and found them safe at typical use levels.
- Common uses
- Sunscreens, Foundations, Waterproof mascaras, Long-wear lip products
- Environmental note
- As a synthetic polymer, it is not biodegradable. However, it is used in small amounts and is not known to accumulate in the environment at concerning levels.
Good to know
- This polymer is often used in combination with other film-formers to fine-tune texture and durability.
- It is considered safe by major regulatory bodies when used as intended in cosmetics.
