VP/Dimethylaminoethylmethacrylate Copolymer
INCI: VP/Dimethylaminoethylmethacrylate Copolymer
A synthetic polymer that helps products spread smoothly, form a flexible film, and improve hold without heavy buildup.
In plain English
This is a synthetic ingredient that creates a thin, flexible film on your skin or hair. In hair products, it helps hold styles without making hair stiff or sticky. In skincare, it can make a product feel silky and help other ingredients stay put. It's a common alternative to older, more drying film formers.

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 VP/Dimethylaminoethylmethacrylate 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 vinylpyrrolidone (VP) and dimethylaminoethylmethacrylate. It belongs to the polyquaternium family and is often listed as Polyquaternium-11.
How it works
When applied, the polymer chains spread out and then dry to form a clear, flexible film. This film can hold hair in place, reduce frizz, or give skin a smooth, slightly taut feel. It also helps other ingredients adhere to the surface.
Pros
Flexible hold
Unlike older polymers that can leave hair stiff or crunchy, this copolymer creates a flexible film that holds style while allowing natural movement.
Smooth feel
In skincare and makeup, it helps products glide on smoothly and leaves a silky, non-greasy finish.
Cons and cautions
Potential buildup
With frequent use, especially in leave-in products, the polymer can accumulate on hair or skin, requiring a clarifying wash to remove.
Synthetic origin
As a lab-made ingredient, it may not appeal to consumers seeking natural or minimal-ingredient formulations.
Best for
- Anyone looking for a flexible, non-sticky hair hold
- People who want a smooth, silky feel in skincare or makeup
Use caution if
- Those following a strictly natural or plant-based routine
- Individuals who prefer to avoid any synthetic film formers
Usage tips
Safety summary
VP/Dimethylaminoethylmethacrylate Copolymer is considered safe for use in cosmetics at typical concentrations. It has a low irritation and comedogenic risk, though some individuals may experience buildup with heavy use.
Research notes
Safety assessments by the Cosmetic Ingredient Review (CIR) panel have concluded that polyquaternium compounds, including this one, are safe for use in cosmetics when formulated to be non-irritating. Studies show it is an effective film former with low toxicity.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics in the US, EU, and many other regions. Considered safe at typical concentrations.
- Common uses
- Hair styling products, Leave-in conditioners, Mascara, Skincare gels
- Environmental note
- As a synthetic polymer, it is not biodegradable. However, it is water-soluble and does not bioaccumulate significantly.
Good to know
- This ingredient is often listed as Polyquaternium-11 on ingredient labels.
- It is water-soluble, so it rinses out more easily than some other film formers.
