Results and discussion
Effect levels
- Sex:
- male/female
- Dose descriptor:
- LD50
- Effect level:
- > 2 000 mg/kg bw
- Mortality:
- No mortalitiy occurred.

Applicant's summary and conclusion
- Interpretation of results:
- practically nontoxic
- Remarks:
- Migrated information
- Conclusions:
- The oral LD50 value of OLIGO-PAP in Wistar rats was established to exceed 2000 mg/kg bw.
- Executive summary:
The acute oral toxicity study of OLIGO-PAP was determined with 3 male and 3 female WISTAR rats. Both male and female rats were treated with 2000 mg/kg bw. Animals were observed for symptoms of clinical toxicity and mortality for 14 days after treatment. Hunched posture was noted in all males on day 1. Hunched posture, lethargy uncoordinated movements and piloerection was noted among the females. The animals had recovered from the symptoms between days 1 and 5. No mortality occured, no apparent changes were found in body weight and necropsy. Therefor the oral LD50 value of OLIGO-PAP in Wistar rats was established to exceed 2000 mg/kg bw. OLIGO-PAP does not have to be classified and has no obligatory labelling requirement for oral toxicity.
