Ingredient review
Hydrogenated Farnesene/C10-16 Olefin Copolymer
INCI: Hydrogenated Farnesene/C10-16 Olefin Copolymer
A gentle, plant-based polymer that helps products stay put without feeling sticky or heavy.
In plain English
This ingredient is a flexible, invisible film that forms on your skin when you apply a product. It helps makeup last longer, keeps sunscreen from washing off easily, and gives a smooth, non-greasy feel. It's made from farnesene, a natural compound found in sugarcane or other plants, so it's considered a more sustainable alternative to some petroleum-based polymers.

Quick decision guide
Useful, but context matters
Hydrogenated Farnesene/C10-16 Olefin Copolymer 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 Hydrogenated Farnesene/C10-16 Olefin Copolymer.
- 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 polymer derived from farnesene, a natural hydrocarbon produced by fermenting plant sugars (often sugarcane). It is chemically modified (hydrogenated) and combined with other olefins to create a flexible, water-resistant film.
How it works
When applied, the copolymer dries to form a thin, flexible film on the skin. This film helps lock in other ingredients, prevents makeup from smudging or transferring, and improves water resistance in sunscreens. It also gives products a silky, spreadable texture without a greasy residue.
Pros
Long-lasting wear
Creates a flexible film that helps makeup and sunscreen stay put for hours, reducing the need for touch-ups.
Smooth, non-greasy feel
Gives a silky, lightweight texture without the heavy or sticky feeling some film-formers leave behind.
Cons and cautions
Requires double cleansing
The water-resistant film doesn't wash off with water alone, so you'll need an oil-based cleanser or micellar water to remove it fully.
May feel drying for some
On very dry or sensitive skin, the film can feel slightly tight or uncomfortable, especially if used in high concentrations.
Best for
- Anyone wanting long-lasting makeup or water-resistant sunscreen
- People who prefer plant-derived ingredients over petroleum-based ones
Use caution if
- Those who prefer completely water-washable, minimal-film products
Usage tips
Safety summary
Considered safe for use in cosmetics at typical concentrations. Low irritation and comedogenic risk. No significant safety concerns reported in regulatory or dermatological literature.
Research notes
Limited peer-reviewed studies specifically on this copolymer, but it is structurally similar to other safe film-forming polymers. Safety is supported by its widespread use in cosmetics and regulatory approvals. More research on long-term environmental impact is needed.
Common label clues
- Typical concentration
- 1–10%
- Regulatory status
- Approved for use in cosmetics globally, including by the EU CosIng database and the US FDA as a cosmetic ingredient. No known restrictions.
- Common uses
- Long-wear foundations, Water-resistant sunscreens, Lip products, Eye makeup
- Environmental note
- Derived from renewable sugarcane fermentation, it has a lower carbon footprint compared to petroleum-based polymers. However, its biodegradability in aquatic environments is still being studied.
Good to know
- Farnesene is produced by fermenting sugarcane, making this a renewable, plant-based alternative to many petroleum-derived polymers.
- It is often used in 'clean' beauty formulations as a silicone alternative.
