About
An aromatic aldehyde occurring naturally in essential oils, used as a fragrance material with mild skin sensitization potential at high concentrations.
Hydrocinnamaldehyde (3-phenylpropanal) is a fragrance ingredient that may require declaration on the EU ingredient list due to its potential to act as a skin sensitizer at elevated concentrations. It is not subject to specific EU concentration limits but falls under the general fragrance allergen labeling requirements of the Cosmetics Regulation. When used at typical fragrance levels, it is considered safe in rinse-off products.
Known concerns
- Potential skin sensitizer at high concentrations
