Ingredient review
DVB/Isbornyl Methacrylate/Laureth Methacrylate Copolymer
INCI: DVB/ISOBORNYL METHACRYLATE/LAURYL METHACRYLATE COPOLYMER
A synthetic film-former that helps makeup last longer and resist water, but offers no active skincare benefit.
In plain English
This ingredient is a plastic-like polymer that dries down to a flexible, invisible film on your skin. It's what makes a foundation stay put all day or a mascara survive a rainy commute. Think of it as a clear, breathable raincoat for your makeup. It doesn't hydrate or treat your skin—it's purely a performance booster for cosmetics.

Quick decision guide
Useful, but context matters
DVB/Isbornyl Methacrylate/Laureth Methacrylate 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 DVB/Isbornyl Methacrylate/Laureth Methacrylate 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, isobornyl methacrylate, and lauryl methacrylate monomers. It's engineered to form a durable, flexible film when applied to skin or hair.
How it works
When the solvent (water or alcohol) evaporates after application, the polymer chains link together into a continuous film. This film physically locks pigments and other ingredients in place, creating a water-resistant, transfer-resistant layer on the skin or lashes.
Pros
Long-lasting wear
Creates a durable film that keeps makeup intact for 12+ hours, even in humidity or rain.
Transfer-resistant
Reduces makeup smudging onto masks, collars, or phone screens, making it ideal for all-day wear.
Cons and cautions
No skincare benefit
Unlike humectants or antioxidants, this polymer does not hydrate, soothe, or protect skin—it's purely cosmetic.
Removal challenge
Because it's water-resistant, you'll need an oil-based or micellar cleanser to fully remove it without rubbing.
Best for
- Anyone wanting long-lasting makeup for events or humid weather
- People who prefer water-resistant sunscreens
Use caution if
- Those with very dry or compromised skin barriers who find film-formers uncomfortable
Usage tips
Safety summary
Generally recognized as safe for topical cosmetic use. Low irritation and comedogenic potential. No significant safety concerns reported in the available literature.
Research notes
Limited peer-reviewed studies specific to this exact copolymer, but the broader class of acrylate/methacrylate copolymers has a long history of safe use in cosmetics. Safety assessments rely on analog data from similar film-forming polymers.
Common label clues
- Typical concentration
- 1–10% in leave-on formulas
- Regulatory status
- Approved for use in cosmetics in the EU, US, and many other regions. No specific concentration limits are imposed, but typical use levels are low.
- Common uses
- Long-wear foundations, Waterproof mascaras, Lip products, Sunscreens
- Environmental note
- As a synthetic polymer, it may not be 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 listed near the end of ingredient lists because it's used at low concentrations.
- It's considered safe for use in cosmetics by major regulatory bodies when used as intended.
