Ingredient review
Isopropyl Ester of PVM/MA Copolymer
INCI: ISOPROPYL ESTER OF PVM/MA COPOLYMER
A synthetic polymer that helps products stay put, resist water, and feel flexible on skin or hair without heavy buildup.
In plain English
This ingredient is a synthetic polymer—a long chain of repeating molecules—that has been chemically modified with isopropyl alcohol to make it more flexible and water-resistant. In cosmetics, it forms a thin, invisible film on your skin or hair that helps other ingredients stay in place, resist sweat or water, and feel less sticky or stiff than older polymers. You'll often find it in long-wear makeup, sunscreens, and hair styling products where durability is key.

Quick decision guide
Useful, but context matters
Isopropyl Ester of PVM/MA 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 Isopropyl Ester of PVM/MA 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 (PVM/MA) that has been esterified with isopropyl alcohol to improve its film-forming and water-resistant properties. It is a clear, slightly viscous liquid that dries to a flexible film.
How it works
When applied, the polymer molecules spread out and link together as the solvent evaporates, forming a continuous, flexible film on the skin or hair. This film helps lock in other ingredients (like sunscreen filters or pigments), resists removal by water or sweat, and provides a smooth, non-tacky feel. The isopropyl ester modification makes the film less brittle and more comfortable than unmodified PVM/MA copolymers.
Pros
Excellent water resistance
Helps sunscreens and makeup resist sweat, humidity, and water exposure, so you don't have to reapply as often.
Flexible, comfortable feel
Unlike older film formers, this polymer dries to a flexible film that moves with your skin or hair, reducing stiffness or flaking.
Cons and cautions
Requires thorough removal
The water-resistant film can trap dirt and oil, so you may need an oil-based cleanser or double cleansing to fully remove it without irritation.
Not eco-friendly
As a synthetic polymer, it is not biodegradable and may contribute to microplastic pollution if washed down the drain.
Best for
- Anyone looking for long-wearing makeup or water-resistant sunscreen
- People with normal to oily skin who want products that stay put without feeling greasy
Use caution if
- Those with very dry or compromised skin barriers who may find film-forming polymers too occlusive or drying
Usage tips
Safety summary
Isopropyl Ester of PVM/MA Copolymer is considered safe for use in cosmetics at typical concentrations. It has low irritation and sensitization potential. However, like all film-forming polymers, it may cause a tight or dry feeling on very sensitive or dry skin. The main environmental concern is its persistence in the environment.
Research notes
Safety assessments by the Cosmetic Ingredient Review (CIR) panel have concluded that this ingredient is safe for use in cosmetics. Studies show it is a mild film former with low skin irritation and sensitization potential. There is limited published research on its environmental fate, but it is classified as a non-biodegradable polymer.
Common label clues
- Typical concentration
- 1% to 10% depending on product type
- Regulatory status
- Approved for use in cosmetics in the US, EU, and many other regions. The Cosmetic Ingredient Review (CIR) panel has reviewed it and found it safe for use in leave-on and rinse-off products at concentrations up to 10%.
- Common uses
- Hair styling products, Sunscreens, Water-resistant makeup, Long-wear foundations
- Environmental note
- As a synthetic polymer, it is not readily biodegradable. Some jurisdictions are considering restrictions on non-biodegradable polymers in rinse-off products to reduce microplastic pollution.
Good to know
- This ingredient is often listed near the end of an ingredient list because it is used at low concentrations.
- It is considered safe by the Cosmetic Ingredient Review (CIR) panel at typical use levels.
- Some brands label it as 'PVM/MA Copolymer' without the 'Isopropyl Ester'—the ester version is more flexible and water-resistant.
