Ingredient review
Octyldodecyl Citrate Crosspolymer
INCI: Octyldodecyl Citrate Crosspolymer
A gentle, silicone-alternative film former that helps makeup and skincare stay put without feeling heavy or greasy.
In plain English
Octyldodecyl Citrate Crosspolymer is a clever ingredient that forms a thin, flexible film on your skin. Think of it like a lightweight, invisible shield that helps your makeup or sunscreen last longer and feel smooth. It's made from citric acid (found in citrus fruits) and fatty alcohols, so it's a more natural-feeling alternative to silicones. It won't clog pores or irritate most skin types.

Quick decision guide
Useful, but context matters
Octyldodecyl 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 Octyldodecyl 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 semi-synthetic polymer created by crosslinking citric acid with octyldodecanol (a fatty alcohol). The result is a large molecule that spreads into an even, breathable film on the skin.
How it works
When applied, the polymer molecules link together as the product dries, forming a continuous, flexible film. This film helps other ingredients (like pigments or UV filters) stay in place, reduces water loss from the skin, and gives a smooth, velvety feel.
Pros
Silicone alternative
Provides a similar smooth, silky feel to silicones but is derived from natural citric acid, appealing to those avoiding silicones.
Improves product longevity
Helps foundation, sunscreen, or primer stay on your skin longer without smudging or fading, so you need fewer touch-ups.
Cons and cautions
Potential tackiness
If too much is applied, the film can feel slightly sticky or tacky, which may be uncomfortable for some users.
Limited research
Compared to traditional film-formers like dimethicone, there is less published research on long-term skin effects, though current data suggests it is safe.
Best for
- Anyone looking for longer-lasting makeup or sunscreen
- People who prefer silicone-free formulas
Use caution if
- Those with very sensitive skin that reacts to film-formers (rare)
Usage tips
Safety summary
Considered safe for topical use at typical concentrations. Low irritation and comedogenic potential. No significant safety concerns reported in cosmetic use.
Research notes
Limited peer-reviewed studies specifically on this polymer, but it is chemically similar to other safe film-formers. Safety assessments by cosmetic ingredient review panels support its use.
Common label clues
- Typical concentration
- 1–10%
- Regulatory status
- Approved for use in cosmetics in the EU, US, and other major markets. No known restrictions.
- Common uses
- Foundations, Sunscreens, Primers, Lip products
- Environmental note
- Derived from renewable citric acid and fatty alcohols. Not known to bioaccumulate, but as a synthetic polymer, its biodegradability varies.
Good to know
- Often listed near the end of ingredient lists because it's used in small amounts.
- Can be found in both leave-on and rinse-off products.
