Results and discussion

Effect levels
Sex:
male/female
Dose descriptor:
LD50
Effect level:
> 2 000 mg/kg bw
Based on:
test mat.
Mortality:
No intercurrent deaths occurred during the course of the study.
Clinical signs:
other: No clinical signs were observed throughout the entire observation period.
Gross pathology:
No macroscopic findings were recorded at necropsy.
Other findings:
All animals showed slight erythema from the beginning of the observation until days three or five and six. Additionally, all animals had slight focal crusts and slight desquamation on several days, in most cases during the six last days of the observation period.

Applicant's summary and conclusion

Interpretation of results:
study cannot be used for classification
Remarks:
Migrated information
Conclusions:
The median lethal dose of (Tetrapropylenesuccinimido)-caproic acid after single dermal administration to male and female rats, observed over a period of 14 days, is: LD50(dermal) (Wistar rat): greater than 2000 mg/kg body weight
Executive summary:

The acute dermal toxicity of the registration substance was assessed based on the read-across approach using (Tetrapropylensuccinimido)-caproic acid as read-across supporting substance.

The acute dermal toxicity of (Tetrapropylensuccinimido)-caproic acid was investigated according to the OECD Guideline 402. At dose level of 2000 mg/kg bw no systemic effect was observed.
