Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Test animals

Species:
rat
Strain:
Wistar
Sex:
male/female

Administration / exposure

Route of administration:
oral: gavage
Vehicle:
polyethylene glycol
Details on oral exposure:
The test item was suspended in PEG 300 at a concentration of 0.2 g/ml and administered at a volume of 10 ml/kg.
Doses:
2000 mg/kg
No. of animals per sex per dose:
One group of 3 male or 3 female rats.
Details on study design:
The animals were examined for clinical signs daily during the acclimatization period four times during test day 1 and oncel daily during test days 2-15. Mortality/viability was recorded daily during the acclimatization period and together with clinical signs at the same time intervals on test day 1 and twice daily on test days 2-15. Body weight were recorded on day 1 (prior to administration) and on days 8 and 15. All animals were necropsied and examined macroscopically.

Results and discussion

Effect levels
Sex:
male/female
Dose descriptor:
LD50
Effect level:
> 2 000 mg/kg bw
Mortality:
All animals survived until the end of the study period.
Clinical signs:
Slightly ruffled fur was noted in male no.5 two and three hours after treatment. No clinical signs were evident in all other animals during the course of the study.
Body weight:
The body weight was within the range commonly recorded for this strain and age.
Gross pathology:
No macroscopic findings were observed at necropsy.

Applicant's summary and conclusion

Interpretation of results:
other: Not classified based on CLP criteria
Conclusions:
The LD50 of TSE8 after single oral administration to rats of both sexes, observed over a period of 14 days is greater than 2000 mg/kg b.w.
