Ingredient review
Hydrogenated Rapeseed/Tung Oil Copolymer
INCI: Hydrogenated Brassica Campestris/Aleurites Fordii Oil Copolymer
A gentle, plant-based film former that helps makeup and skincare stay put without clogging pores.
In plain English
This ingredient is a modified plant oil that has been hydrogenated (hardened) and turned into a polymer (a long chain of molecules). In cosmetics, it creates a thin, flexible film on the skin or hair. This film helps other ingredients stay in place, reduces water loss, and gives products a smooth, non-greasy feel. Think of it like a clear, breathable shield that helps your makeup last longer or your moisturizer stay effective.

Quick decision guide
Useful, but context matters
Hydrogenated Rapeseed/Tung Oil 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 Rapeseed/Tung Oil 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 semi-synthetic polymer made by hydrogenating and copolymerizing oils from rapeseed (Brassica campestris) and tung tree (Aleurites fordii) seeds. The hydrogenation process makes the oils more stable and solid at room temperature, while copolymerization creates a film-forming material.
How it works
When applied, the copolymer forms an even, flexible film on the skin or hair surface. This film acts as a barrier that slows water evaporation (improving moisturization), helps pigments and active ingredients adhere better, and provides a smooth, silky feel. It also thickens the product formula, giving it a richer texture.
Pros
Long-wear support
Helps makeup and skincare products stay in place for hours without smudging or fading.
Smooth texture
Gives products a silky, non-tacky feel that glides on easily and leaves a soft finish.
Cons and cautions
Potential heaviness
On very oily skin, the film may feel slightly occlusive or heavy, possibly contributing to a greasy look.
Limited research
While generally considered safe, there are fewer peer-reviewed studies on this specific copolymer compared to more common film formers.
Best for
- Anyone wanting longer-lasting makeup
- People with dry or normal skin looking for a smooth finish
- Those who prefer plant-derived ingredients
Use caution if
- Individuals with very oily or acne-prone skin who may find film-formers too heavy
Usage tips
Safety summary
Generally recognized as safe for topical use. Low irritation and comedogenic potential. No significant safety concerns reported in cosmetic use.
Research notes
Limited but consistent evidence supports its function as a film former and viscosity agent. Safety assessments by industry panels (e.g., CIR) have not flagged major concerns.
Common label clues
- Typical concentration
- 1–10%
- Regulatory status
- Approved for use in cosmetics in the EU, US, and many other regions. No known restrictions at typical use levels.
- Common uses
- Lipsticks, Foundations, Mascaras, Sunscreens, Long-wear formulas
- Environmental note
- Derived from renewable plant sources (rapeseed and tung tree). The hydrogenation process is energy-intensive but the final ingredient is biodegradable.
Good to know
- This ingredient is often used in 'transfer-proof' lipsticks and foundations.
- It is vegan-friendly as it is derived from plant oils.
- Hydrogenation makes the oil more stable and less likely to go rancid.
