Ingredient review
Hexanediol/Adipate/Citrate Crosspolymer
INCI: HEXANEDIOL/ADIPATE/CITRATE CROSSPOLYMER
A gentle, non-greasy film former that helps products spread evenly and stay put without clogging pores.
In plain English
This is a synthetic polymer that forms a thin, flexible film on your skin. It helps makeup and skincare products glide on smoothly, feel lightweight, and last longer. Think of it as a clear, breathable layer that holds ingredients in place without feeling heavy or sticky.

Quick decision guide
Useful, but context matters
Hexanediol/Adipate/Citrate Crosspolymer 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 Hexanediol/Adipate/Citrate Crosspolymer.
- 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 crosslinked polymer made from hexanediol, adipic acid, and citric acid. It is designed to create a flexible, water-resistant film on the skin.
How it works
When applied, the polymer dries into a thin, invisible film that helps other ingredients stay on the skin's surface. This improves the wear time of makeup and sunscreens, and can also give a silky, smooth feel to the product.
Pros
Lightweight feel
Unlike heavier waxes or oils, this polymer creates a thin, flexible film that doesn't feel sticky or greasy on the skin.
Improves product longevity
Helps makeup and sunscreen stay in place longer, reducing the need for frequent touch-ups or reapplication.
Cons and cautions
Potential tightness on dry skin
The film can feel slightly tight or uncomfortable if your skin is already dry or dehydrated, especially in cold weather.
Environmental persistence
As a synthetic polymer, it is not biodegradable and may accumulate in the environment over time.
Best for
- People who want long-wearing makeup or sunscreen
- Those with oily or combination skin who prefer a matte, non-greasy finish
Use caution if
- Individuals with very dry or dehydrated skin who may find film formers uncomfortable
Usage tips
Safety summary
Hexanediol/Adipate/Citrate Crosspolymer is considered safe for topical use in cosmetics. It has low irritation and comedogenic potential, making it suitable for most skin types. However, individuals with very dry or sensitive skin may experience mild tightness.
Research notes
Research on this specific polymer is limited, but it is chemically similar to other polyester film formers that have been evaluated for safety. Studies on related polyesters indicate low skin irritation and sensitization potential. More research is needed on its environmental fate.
Common label clues
