Ingredient review
PEG/PPG Copolymer Film Former
INCI: PHTHALIC ANHYDRIDE/ADIPIC ACID/CASTOR OIL/NEOPENTYL GLYCOL/PEG-3/TRIMETHYLOLPROPANE COPOLYMER
A synthetic film former that helps makeup and sunscreen stay put, but its long-chain polymer structure means it's not easily absorbed and may feel heavy on some skin types.
In plain English
This ingredient is a man-made polymer (a long chain of repeating units) that forms a thin, flexible film on your skin or hair. Think of it like a clear, invisible coat that helps makeup last longer, keeps sunscreen from washing off, or gives hair hold without flaking. It's not absorbed into the skin—it sits on top and creates a barrier. Because it's a large molecule, it's unlikely to clog pores or cause irritation for most people, but it can feel a bit sticky or heavy if you're sensitive to film-forming ingredients.

Quick decision guide
Useful, but context matters
PEG/PPG Copolymer Film Former 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 PEG/PPG Copolymer Film Former.
- 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 by combining phthalic anhydride, adipic acid, castor oil, neopentyl glycol, PEG-3, and trimethylolpropane. The result is a flexible, water-resistant film former commonly used in cosmetics to improve wear time and texture.
How it works
When applied, the copolymer molecules spread out and link together as the solvent (water or alcohol) evaporates, forming a continuous, flexible film. This film adheres to the skin or hair, creating a barrier that resists water, sweat, and rubbing. It also helps other ingredients (like pigments or UV filters) stay in place longer.
Pros
Long-lasting wear
Helps makeup and sunscreen stay put for hours, even in humid or sweaty conditions.
Water-resistant barrier
Creates a protective film that resists water and sweat, ideal for swim or gym use.
Cons and cautions
Can feel heavy
The film may feel sticky or heavy on oily skin, and some users report a tight sensation after application.
Requires thorough removal
Because it forms a strong film, you may need an oil-based cleanser or double cleansing to fully remove it, which can be inconvenient.
Best for
- People who want long-wearing makeup or waterproof sunscreen
- Those with normal to dry skin who don't mind a film feel
Use caution if
- Individuals with very oily or acne-prone skin who prefer lightweight, breathable formulas
Usage tips
Safety summary
Considered safe for cosmetic use by major regulatory bodies. The polymer is too large to penetrate skin, so systemic exposure is negligible. Rare reports of mild irritation in sensitive individuals, but overall low risk.
Research notes
Limited peer-reviewed studies specifically on this copolymer, but film-forming polymers in general are well-studied for safety and efficacy. The Cosmetic Ingredient Review (CIR) panel has reviewed similar copolymers and found them safe for use.
Common label clues
- Typical concentration
- 1–10% in rinse-off products; up to 20% in leave-on formulas
- Regulatory status
- Approved for use in cosmetics in the EU, US, and other major markets. The phthalic anhydride component is fully reacted into the polymer, so it does not release free phthalates. No known safety concerns at typical use levels.
- Common uses
- Long-wear makeup, Waterproof mascara, Sunscreen, Hair styling products
- Environmental note
- As a synthetic polymer, it is not biodegradable and may contribute to microplastic pollution. Some brands are moving toward biodegradable film formers.
Good to know
- This ingredient is often listed near the end of ingredient lists because it's used in small amounts.
- It's commonly found in 'transfer-proof' or '24-hour wear' makeup claims.
