RIFM fragrance ingredient safety assessment, 7,9-dimethylspiro[5.5]undecan-3-one, CAS Registry Number 83863-64-3
(2021) In Food and Chemical Toxicology 149.- Abstract
The existing information supports the use of this material as described in this safety assessment. 7,9-Dimethylspiro[5.5]undecan-3-one was evaluated for genotoxicity, repeated dose toxicity, reproductive toxicity, local respiratory toxicity, phototoxicity/photoallergenicity, skin sensitization, and environmental safety. Data show that 7,9-dimethylspiro[5.5]undecan-3-one is not genotoxic. The repeated dose, reproductive, and local respiratory toxicity endpoints were evaluated using the Threshold of Toxicological Concern (TTC) for a Cramer Class II material, and the exposure to 7,9-dimethylspiro[5.5]undecan-3-one is below the TTC (0.009 mg/kg/day, 0.009 mg/kg/day, and 0.47 mg/day, respectively). Based on the existing data and readacross... (More)

The repeated dose, reproductive, and local respiratory toxicity endpoints were evaluated using the Threshold of Toxicological Concern (TTC) for a Cramer Class II material, and the exposure to 7,9-dimethylspiro[5.5]undecan-3-one is below the TTC (0.009 mg/kg/day, 0.009 mg/kg/day, and 0.47 mg/day, respectively). Based on the existing data and readacross material spiro[5.5]undec-8-en-1-one, 2,2,7,9-tetramethyl- (CAS # 502847-01-0), 7,9-dimethylspiro[5.5]undecan-3-one presents no concern for skin sensitization under the current, declared levels of use. The phototoxicity/photoallergenicity endpoints were evaluated based on data and ultraviolet (UV) spectra; 7,9-dimethylspiro[5.5]undecan-3-one is not phototoxic/photoallergenic. The environmental endpoints were evaluated; 7,9-dimethylspiro[5.5]undecan-3-one was found not to be Persistent, Bioaccumulative, and Toxic (PBT) as per the International Fragrance Association (IFRA) Environmental Standards, and its risk quotients, based on its current volume of use in Europe and North America (i.e., Predicted Environmental Concentration/Predicted No Effect Concentration [PEC/PNEC]), are <1.
