Formulation
Stability
Delta-undecalactone demonstrates stable performance across a broad pH range of 4.0 to 10.0 and tolerates heat processing up to 180°C. However, lactones can polymerize over time, potentially leading to increased viscosity or phase changes in alcohol-based formulations. Optimal stability is maintained with cool, dark storage and the inclusion of antioxidants.
Conflicts
- Excessive use alongside intensely green or marine fragrance notes may result in an undesirable scent clash.
Safety
Safety Profile
The Research Institute for Fragrance Materials (RIFM) has concluded that delta-undecalactone poses no concern for skin sensitization at current declared usage levels. While initial cytotoxicity was observed in a Blue-Screen assay without metabolic activation, subsequent testing for genotoxicity and re-evaluation with metabolic activation yielded negative results for both cytotoxicity and genotoxicity. It holds FEMA GRAS status and is recognized as a flavoring agent by the FDA and JECFA, indicating no safety concern at typical intake levels. In finished consumer products, its recommended dosage is up to 0.001% (10 ppm).
