Ingredient review
Dimethylbicycloheptenylethanone
INCI: DIMETHYLBICYCLO-5-HEPTEN-2-YLETHANONE
A synthetic fragrance compound that adds scent but offers no skincare benefits; safe at low levels but may cause sensitivity in some individuals.
In plain English
This is a man-made chemical added to give products a pleasant smell, often described as fresh, floral, or woody. It doesn't moisturize, treat, or improve your skin—it's purely for fragrance. Like many fragrance ingredients, it's generally safe in tiny amounts but can be irritating for people with sensitive skin or allergies.

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 Dimethylbicycloheptenylethanone.
- 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 organic compound from the bicyclic ketone family, created in a lab to produce a specific scent profile. It is not derived from plants or natural sources.
How it works
It evaporates from the skin's surface, releasing molecules that interact with olfactory receptors in the nose. In the product, it simply provides a fragrance experience and has no active skin benefit.
Pros
Pleasant scent
Adds a fresh, floral, or woody note that can make your skincare routine more enjoyable.
Low irritation at low levels
When used in small amounts, it rarely causes problems for most people without fragrance sensitivities.
Cons and cautions
No skincare benefit
It only adds scent—it doesn't hydrate, protect, or improve your skin in any way.
Potential allergen
Like many fragrance ingredients, it can cause contact dermatitis or allergic reactions in sensitive individuals, especially with repeated use.
Best for
- People who enjoy scented skincare and have no history of fragrance allergies
- Those using rinse-off products like body washes where exposure is brief
Use caution if
- Individuals with known fragrance allergies or sensitive, reactive skin
- Anyone preferring fragrance-free skincare to minimize irritation risk
Usage tips
Safety summary
Generally recognized as safe for use in cosmetics at low concentrations. However, it is a known potential skin sensitizer, so individuals with fragrance allergies should avoid it.
Research notes
Research primarily focuses on its fragrance properties and sensitization potential. It is not associated with significant toxicity at cosmetic use levels, but allergic contact dermatitis has been reported in patch test studies.
Common label clues
- Typical concentration
- Typically used at very low levels, often below 1% in leave-on products
- Regulatory status
- Approved for use in cosmetics in the EU, US, and other major markets, with usage limits recommended by IFRA to minimize sensitization risk.
- Common uses
- Fragranced skincare, Perfumes, Body lotions, Cleansers
- Environmental note
- As a synthetic compound, it may not be biodegradable and could accumulate in the environment, though data is limited.
Good to know
- Fragrance ingredients like this one are often listed simply as 'fragrance' or 'parfum' on labels, so you may not see this specific name.
- Regulatory bodies like the IFRA (International Fragrance Association) set safe usage limits for this ingredient in cosmetics.
