Ingredient review
Phthalate-Free Film Former
INCI: Glycol/Neopentyl Glycol/Phthalic Anhydride Copolymer Benzoate
A safe, synthetic film former that helps products stay put without clogging pores or irritating skin.
In plain English
This is a man-made polymer that dries down to a thin, flexible film on your skin or hair. It's often used in sunscreens and long-wear makeup to help them resist water and sweat, and in hair products to hold a style without stiffness. Despite its long chemical name, it's not related to harmful phthalates and is considered very gentle.

Quick decision guide
Useful, but context matters
Phthalate-Free 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 Phthalate-Free 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 created by reacting glycols, neopentyl glycol, and phthalic anhydride, then modified with benzoate. It belongs to the polyester family and is designed to form a durable yet flexible film.
How it works
When applied, the polymer's molecules link together as the solvent evaporates, creating a continuous, invisible film. This film acts as a barrier that slows water loss from the skin (reducing trans-epidermal water loss) and helps other ingredients stay in place. On hair, it coats each strand to provide hold and humidity resistance.
Pros
Water-resistant barrier
Forms a flexible film that helps sunscreens and makeup resist water and sweat, so you stay protected longer during outdoor activities.
Gentle on skin
Rated low for both irritation and comedogenicity, meaning it's unlikely to cause breakouts or stinging, even for sensitive skin types.
Cons and cautions
Synthetic origin
As a man-made polymer, it may not fit a 'natural-only' routine. Some consumers prefer plant-based alternatives for environmental or personal reasons.
Potential tightness
In high concentrations or on very dry skin, the film can feel slightly tight or drying, similar to a light mask effect.
Best for
- Anyone wanting long-wearing, water-resistant makeup or sunscreen
- People with oily or combination skin who prefer a matte finish
Use caution if
- Those who strictly avoid all synthetic ingredients in their routine
Usage tips
Safety summary
Extensively reviewed and considered safe for cosmetic use. It is non-irritating, non-sensitizing, and non-comedogenic. The ingredient is not a phthalate and poses no known health risks at typical use levels.
Research notes
Safety assessments by the Cosmetic Ingredient Review (CIR) panel have concluded that similar polyester copolymers are safe as used in cosmetics. No significant human or environmental toxicity has been reported in peer-reviewed literature.
Common label clues
- Typical concentration
- 1–10%
- Regulatory status
- Approved for use in cosmetics globally, including by the U.S. FDA and EU CosIng database, with no concentration restrictions.
- Common uses
- Sunscreens, Long-wear makeup, Hair styling products, Water-resistant formulas
- Environmental note
- As a synthetic polymer, it is not biodegradable. However, it is used in low concentrations and is not known to bioaccumulate.
Good to know
- Despite 'phthalic anhydride' in its name, this ingredient is not a phthalate and is not associated with the health concerns linked to phthalates.
- It is often listed simply as 'Polyester-5' on ingredient labels for brevity.
