The Formula
Formulation
Stability
As an ester, Isononyl Acetate is prone to hydrolysis, which can lead to the formation of its corresponding acid and potentially impact formulation stability over time.
Conflicts
- strong oxidizing acids (can cause vigorous, exothermic reactions)
- caustic solutions (generate heat)
- alkali metals
- hydrides (generate flammable hydrogen)
Safety
Safety Profile
A safety assessment by the Research Institute for Fragrance Materials (RIFM) concluded that Isononyl Acetate does not present a concern for skin sensitization, genetic toxicity, phototoxicity, or photoallergenicity. The RIFM also indicated that current exposure levels (19 μg/kg bw/day) are below the Threshold of Toxicological Concern (TTC) of 30 μg/kg bw/day. While a direct CIR final report of 'safe as used' is not available, the RIFM assessment provides strong safety indications for its use as a fragrance ingredient.
