- IUPAC: 2-benzylideneheptanal
2-Benzylideneheptanal (Amyl Cinnamal) (CAS 122-40-7) appears in 1 of the 1,812 car-care products CarCareTruth tracks (as of June 2026).
EU CLP ingredient-level classification H400 (very toxic to aquatic life) and H411 (toxic to aquatic life with long lasting effects). At typical use concentrations (<0.2%), the mixture-level aquatic hazard may not be classified — the ingredient-level aquatic toxicity is the relevant signal.
2-Benzylideneheptanal (also known as amyl cinnamal or α-amylcinnamaldehyde) is a synthetic fragrance aldehyde used to impart a jasmine-like floral note. It appears on the EU Commission's list of 26 identified fragrance allergens and must be disclosed when present above 0.01% in rinse-off products or 0.001% in leave-on products.
The primary environmental concern is aquatic toxicity — classified H400 (Aquatic Acute Cat 1) and H411 (Aquatic Chronic Cat 2) at the ingredient level. Products containing this ingredient at sub-percent concentrations may not carry mixture-level aquatic GHS codes if the contribution is below classification thresholds, but the ingredient-level toxicity applies for CCT environment scoring purposes.
