Ingredient review
Acrylate Film Former
INCI: GLYCIDYL C8-11 ACIDATE/GLYCERIN/PHTHALIC ANHYDRIDE COPOLYMER
A synthetic film former that helps products stay put, but its phthalate-related name may cause confusion — it is not a phthalate of concern.
In plain English
This is a man-made polymer that dries down to form a thin, flexible film on your skin or hair. Think of it like a clear, breathable plastic wrap that helps makeup last longer or sunscreen stay water-resistant. Despite its long chemical name, it is not related to the phthalates that have raised health concerns in the past.

Quick decision guide
Useful, but context matters
Acrylate 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 Acrylate 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 glycidyl C8-11 acidate, glycerin, and phthalic anhydride. It belongs to a class of ingredients called film formers, which are designed to create a continuous layer on the skin or hair.
How it works
When applied, the copolymer's molecules link together as the solvent (usually water or alcohol) evaporates, forming a uniform, flexible film. This film helps other ingredients (like pigments or UV filters) adhere better and resist removal by water, sweat, or friction.
Pros
Boosts product longevity
Creates a durable film that helps makeup and sunscreen stay in place for hours, even in humid conditions.
Improves water resistance
Forms a barrier that resists water and sweat, making it ideal for swim-proof sunscreens and long-wear foundations.
Cons and cautions
Name causes confusion
The word 'phthalic' in the name often leads people to worry about harmful phthalates, but this ingredient is chemically distinct and not classified as a phthalate of concern.
May feel drying
The film can sometimes feel tight or drying on very dry or sensitive skin, especially in high concentrations.
Best for
- Anyone wanting long-lasting makeup or water-resistant sunscreen
- People with normal to oily skin who prefer a matte finish
Use caution if
- Those with very dry or compromised skin barriers, as the film may feel restrictive
Usage tips
Safety summary
Considered safe for use in cosmetics at typical concentrations. The ingredient is not a phthalate of concern, and no significant irritation or sensitization has been reported in standard safety tests.
Research notes
Limited peer-reviewed studies specifically on this copolymer, but the broader class of acrylate film formers has been reviewed by the Cosmetic Ingredient Review (CIR) panel and deemed safe as used.
Common label clues
- Typical concentration
- Typically 1–10% in leave-on products
- Regulatory status
- Approved for use in cosmetics in the EU, US, and many other regions. The phthalic anhydride used in its manufacture is fully reacted and not present as a free phthalate.
- Common uses
- Long-wear makeup, Water-resistant sunscreens, Hair styling products
- 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.
Good to know
- This ingredient is not related to the phthalates (like DEHP, DBP) that have been restricted in cosmetics due to health concerns.
- It is often used in combination with other film formers to fine-tune flexibility and durability.
