Ingredient review
Ethylhexylbicycloheptene Dicarboximide
INCI: ETHYLHEXYLBICYCLOHEPTENE DICARBOXIMIDE
A synthetic UV filter that effectively absorbs UVA and UVB rays, commonly used in sunscreens for broad-spectrum protection.
In plain English
This ingredient is a man-made compound that works like a tiny sponge for ultraviolet light. When you apply it to your skin, it soaks up UV rays from the sun and converts them into harmless heat, preventing them from damaging your skin cells. It's often combined with other sun filters to provide broad-spectrum protection against both UVA (aging) and UVB (burning) rays.

Quick decision guide
Useful, but context matters
Ethylhexylbicycloheptene Dicarboximide 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 Ethylhexylbicycloheptene Dicarboximide.
- 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
Ethylhexylbicycloheptene Dicarboximide is a synthetic organic compound designed specifically to absorb ultraviolet radiation. It belongs to a class of ingredients called UV filters, which are the active components in sunscreens.
How it works
When UV light hits your skin, this molecule absorbs the energy from the rays. The energy excites the molecule, which then releases that energy as heat, effectively neutralizing the UV radiation before it can penetrate deeper into your skin and cause damage like sunburn, premature aging, or DNA mutations.
Pros
Effective UV Protection
Absorbs both UVA and UVB rays, helping to prevent sunburn and long-term skin damage like premature aging.
Good Formulation Compatibility
Works well with other sunscreen ingredients and can be used in lightweight, non-greasy formulas that feel comfortable on the skin.
Cons and cautions
Synthetic Origin
As a man-made chemical, it may not be preferred by those seeking natural or mineral-based sun protection.
Limited Long-Term Data
While generally considered safe, there is less long-term research on this specific filter compared to more common ones like avobenzone or zinc oxide.
Best for
- Anyone seeking effective sun protection
- People with normal to oily skin who prefer lightweight sunscreens
Use caution if
- Those with known allergies or sensitivities to synthetic UV filters
Usage tips
Safety summary
Generally recognized as safe for topical use in sunscreens at approved concentrations. Skin irritation is rare, but patch testing is recommended for sensitive individuals.
Research notes
Moderate evidence supports its effectiveness as a UV absorber. More research is needed on long-term systemic absorption and environmental fate.
Common label clues
- Typical concentration
- Up to 10% in sunscreens
- Regulatory status
- Approved as a UV filter in sunscreens in the European Union and other regions, with maximum concentration limits typically around 10%.
- Common uses
- Sunscreens, Daily moisturizers with SPF, Anti-aging products
- Environmental note
- Some synthetic UV filters have been detected in aquatic environments; however, this specific ingredient has not been widely studied for environmental impact.
Good to know
- Often combined with other UV filters to achieve broad-spectrum protection.
- Approved for use in sunscreens in many countries, including the EU and Asia.
