Applicant's summary and conclusion
- Interpretation of results:
- not classified
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- Under the conditions of the present study, single dermal application of the test item bis (2,3-epoxypropyl)terephthalate to rats at a dose of 2000 mg/kg body weight was associated with no mortality and very slight signs of toxicity as well as very slight signs of irritation.
- Executive summary:
Male and female rats (WISTAR) were treated dermally by semi-occlusive application during 24 hours at a dosage of 2000 mg/kg body weight. The test item was applied undiluted (only moistened with cottonseed oil to ensure good contact). The animals were observed 30 minutes, 1h, 2h, 3h and 4h after the start of dosing and then once daily for 14 days. The animals were weighed on day 1 (prior to the application) and on days 8 and 15.
No deaths occurred during the course of the study.Very slight signs of toxicity as well as very slight signs of irritation were observed during the course of the study.
No abnormal body weight changes were noted.
At necropsy, no changes were noted.
The acute dermal median lethal dose (LD50) of bis(2,3 -epoxypropyl)terephthalate in rats is greather than 2000 mg/kg body weight.
