Ingredient review
Vinylbenzylcyclohexyl Propionamide Copolymer
INCI: VINYLBENZYLCYCLOHEXYL PROPIONAMIDE/VINYLBENZYL LACTOSYLLACTONAMIDE COPOLYMER
A synthetic film-forming polymer that helps products stay put and resist water, but offers no active skincare benefit.
In plain English
This ingredient is a man-made polymer that dries down into a thin, flexible film on your skin. Think of it like a clear, breathable wrap that helps other ingredients (like sunscreen or makeup) stay in place longer and resist sweat or water. It doesn't moisturize or treat skin—it's purely a functional helper for product performance.

Quick decision guide
Useful, but context matters
Vinylbenzylcyclohexyl Propionamide 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 Vinylbenzylcyclohexyl Propionamide 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 created by combining vinylbenzylcyclohexyl propionamide and vinylbenzyl lactosyllactonamide monomers. It belongs to a class of film-forming polymers used in cosmetics to improve wear time and water resistance.
How it works
When applied, the polymer chains spread across the skin and, as the solvent evaporates, they link together to form a continuous, flexible film. This film physically locks in other ingredients and creates a barrier that slows water loss from the product (not from the skin) and resists rubbing off.
Pros
Boosts wear time
Helps sunscreen and makeup stay effective longer, even during sweating or swimming, so you don't have to reapply as often.
Water-resistant finish
Forms a protective film that resists water, making it ideal for beach days or active lifestyles.
Cons and cautions
No active skin benefit
This ingredient doesn't hydrate, soothe, or repair skin—it's purely a performance enhancer for the product itself.
Can feel heavy
On very dry or sensitive skin, the film may feel tight or uncomfortable, and it may require double cleansing to remove fully.
Best for
- Anyone wanting long-wearing sunscreen or makeup
- People who swim, sweat, or live in humid climates
Use caution if
- Those who prefer minimal-ingredient, 'skin-food' routines
Usage tips
Safety summary
Considered safe for topical use at typical concentrations. Low irritation and comedogenic risk. No known toxicity or endocrine disruption concerns based on available data.
Research notes
Limited peer-reviewed studies specific to this copolymer, but film-forming polymers as a class are well-studied for safety and function. Regulatory bodies (e.g., CIR, SCCS) have reviewed similar polymers and found them safe for cosmetic use.
Common label clues
- Typical concentration
- Typically 0.5–5% in leave-on products
- Regulatory status
- Approved for use in cosmetics in the EU, US, and other major markets. No specific restrictions beyond general cosmetic safety requirements.
- Common uses
- Sunscreens, Long-wear makeup, Water-resistant lotions
- Environmental note
- As a synthetic polymer, it may not be biodegradable. Its environmental impact depends on formulation and disposal, but it is not known to bioaccumulate.
Good to know
- This polymer is often found in 'sport' or 'water-resistant' sunscreens.
- It is not absorbed into the skin—it stays on the surface as a film.
