Materials and methods

Test guideline
Qualifier:
no guideline available
Principles of method if other than guideline:
Swiss mice were given intraperitoneally solns, of cyelopentanone (I), cyclohexanone (II), cycloheptanone (III), and cyclo-octanone (IV) in neutralized olive oil. The observation period was 30 days. Letal doses, clinical signs and body temerature were collected.

Results and discussion

Effect levels
Sex:
male/female
Dose descriptor:
LD50
Effect level:
0.74 other: g/kg
Remarks on result:
other: LD50: 0.74 g/kg equals 5.8 mM/kg
Clinical signs:
immediately after injection agitation and aggressivity , followed by coma, bradypnea, arrhythmia, loss of musclue tone and fast death
Other findings:
Decrease in body temperature at LD50: 3.0 °C (max. 3.7°C)

Any other information on results incl. tables

At lower doses, the animals were restless and aggressive, followed by a stage of torpor. The respiration was first accelerated, then became slower and arythmic, accompanied by a drop in body temperature. The time until seizure was determined to be 6h for cyclooctanone.

Applicant's summary and conclusion

Conclusions:
Based on limited reliability of the study, cyclooctanone does not require classification for acute toxicity.
