Safety Profile
The Research Institute for Fragrance Materials (RIFM) has conducted a comprehensive safety assessment for 2,4,4,7-tetramethylnona-6,8-dien-3-one, evaluating endpoints including genotoxicity, repeated dose toxicity, reproductive toxicity, local respiratory toxicity, phototoxicity/photoallergenicity, and skin sensitization. Based on available data, it presents no concern for genotoxic potential. While repeated dose toxicity data is limited, the total systemic exposure at current use levels (0.15 μg/kg bw/day) falls significantly below the Threshold of Toxicological Concern (TTC) of 30 μg/kg bw/day for a Cramer Class I material. GHS classification indicates it is harmful to aquatic life with long-lasting effects (H412) in 93.5% of reports. No specific Cosmetic Ingredient Review (CIR), Scientific Committee on Consumer Safety (SCCS), or FDA status for cosmetic use was found.
