About
A bicyclic aldehyde fragrance chemical with a complex woody-camphoraceous odor profile used in perfume compositions.
Tetramethylbicyclo-2-heptene-2-propionaldehyde is a bicyclic aldehyde derived from norbornane/terpene chemistry functioning as a fragrance ingredient. It is not listed in EU Cosmetics Regulation Annexes II or III. Like many polycyclic aldehydes, it may present mild sensitization potential at high concentrations, though at typical fragrance use levels (below 1%), the risk is considered manageable under IFRA standards. Aldehydes in general can be reactive in skin, but the norbornane backbone reduces volatility and systemic absorption.
Skin benefits
- Functions as a fragrance material in perfumes and scented cosmetics
Known concerns
- Potential aldehyde-type skin sensitization at high concentrations
