DETERMINATION OF CYTOTOXICITY, OTHER EXAMINATIONS:
The plates were examined for the existence of a normal background lawn and/or precipitates and microscopically for microcolony growth. - Statistics:
- Using a X2-test, the statistical significance of the difference between the mean number of revertants in the negative controls and the plates at each dosage level were calculated.

Citronellyl acetate 'mono' did not induce a significant increase in the mutation frequency of the mutant strains of Salmonella typhimurium (TA1535, TA1537, TA98, TA100, and TA102) in the presence and absence of a metabolic activation system.
Applicant's summary and conclusion
- Conclusions:
- Citronellyl Acetate 'mono' did not induce a significant increase in the mutation frequency of the mutant strains of Salmonella typhimurium (TA1535, TA1537, TA98, TA100, and TA102) in the presence and absence of a metabolic activation system. Under the experimental conditions described, Citronellyl Acetate 'mono' was not mutagenic in bateria.
- Executive summary:
For Citronellyl Acetate ‘mono’, an Ames test was performed according to OECD TG 471 and in compliance with GLP criteria. The substance did not induce a significant increase in the mutation frequency of the mutant strains of Salmonella typhimurium (TA1535, TA1537, TA98, TA100 and TA102) in the presence and absence of a metabolic activation system.
