RIFM fragrance ingredient safety assessment, 1-cyclohexylethyl butyrate, CAS Registry Number 63449-88-7

The use of this material under current conditions is supported by existing information. This material was evaluated for genotoxicity, repeated dose toxicity, developmental and reproductive toxicity, local respiratory toxicity, phototoxicity/photoallergenicity, skin sensitization, as well as environmental safety. Data show that this material is not genotoxic. Data from the suitable read across analogue d-cyclocitronellene acetate (CAS # 25225-10-9) show that this material does not have skin sensitization potential. The repeated dose, reproductive and local respiratory toxicity endpoints were completed using the TTC (Threshold of Toxicological Concern) for a Cramer Class I material (0.03, 0.03 mg/kg/day and 1.4 mg/day, respectively). The developmental toxicity endpoint was completed using data from the target material which provided a MOE >100. The phototoxicity/photoallergenicity endpoint was completed based on suitable UV spectra. The environmental endpoint was completed as described in the RIFM Framework
