Remarks on result:

other: Unspecific toxicity observed on day of application. No further effects were observed.

Any other information on results incl. tables

On day of application the treated animals responded with unspecific intoxication signs. These included increased respiration rate, irregualr respiration, stupor, coat bristling, flanks drawn in, stilted gait, ataxic gait, prone position, squatting posture, clonic convulsions, trembling, fissure narros, narcosis, no corneal reflex, reduced pawreflex to pincing, no pawreflex to pinching, no lacing reaction and creased spontaneous activity. All these effects disappeared within 24 hours. The treated animals exhibited normal body weight development in the observation period of 14 days.

Applicant's summary and conclusion

Interpretation of results:

not classified

Remarks:

Migrated information Criteria used for interpretation of results: EU

Conclusions:

No classification is assigned for the registration substance for the endpoint acute oral toxicity.

Executive summary:

The acute oral toxicity of the registration substance was investigated according to the OECD Guideline 401. 5 male and 5 female rats were treated with triethyleneglycoldibutylether (representative material for the registration substance) at dose of 2000 mg/kg bw via gavage. No mortality occured. On the application day unspecific toxicity signs were observed, which disappeared within 24 hours. The treated animals exhibited normal body weight development in the observation period of 14 days. The acute oral toxicity of the registration substance is found to be of no concern.
