Safety Profile

CIR Status
Not reviewed
Sensitization risk High

The Expert Panel for Cosmetic Ingredient Safety (CIR) does not review ingredients solely functioning as fragrances, deferring their safety assessment to the Research Institute for Fragrance Materials (RIFM). For 4-isopropyl-alpha-methyl cinnamaldehyde (CAS 831-97-0), GHS classification indicates 'Skin irritation, Category 2' (H315), signifying it causes skin irritation. It may also induce an allergic skin reaction (H317) and its use is restricted by the IFRA (49th Amendment) due to documented dermal sensitization concerns.
