- Details on oral exposure:
- Single oral exposure

- Control animals:
- no
- Details on study design:
- This study was conducted as a limit study with the dose level of 2000 mg a.i./kg body weight. The first rat was given a single dose of 2000 mg a.i. Methacryloxyisopropyl Acid Phthalate/kg body weight. No mortality was observed at this dose level up to 48 h post dosing. Therefore, rat N° 2, 3, 4 and 5 were treated with the same dose level of 2000 mg a.i. Methacryloxyisopropyl Acid Phthalate/kg body weight, one at a time, separated by minimum 48 h intervals. All rats survived at the dose level of 2000 mg a.i. Methacryloxyisopropyl Acid Phthalate/kg body weight, the end point was achieved and further testing was not required

Applicant's summary and conclusion

- Conclusions:
- The LD50 was estimated to be greater than 2000 mg a.i. Methacryloxyisopropyl Acid Phthalate/kg body weight in female Wistar rats.
- Executive summary:
An acute oral toxicity study (Up-and-Down Procedure) was conducted using five female Wistar rats given a single oral dose of Methacryloxyisopropyl Acid Phthalate (Undiluted, as received). A limit Test was conducted with 2000 mg a.i./kg body weight. Doses were corrected for the purity of the material. The first rat survived; hence the four additional female Wistar rats each received a single dose of 2000 mg a.i./kg body weight according to the Up-and-Down Procedure.
No sign of toxicity was observed in the rats treated with theMethacryloxyisopropyl Acid Phthalateat 2000 mg a.i./Kg body weight.
All rats were active and healthy during the study. All rats gained body weight by the end of the study period.
External and visceral examination of terminally sacrificed rats did not reveal any lesions of pathological significance. In absence of any pathological lesion in terminally sacrificed animals, it is concluded that the test item did not produce any treatment related effect at the dose level used in the present study.
The acute oral estimated LD50of the Methacryloxyisopropyl Acid Phthalate was estimated to be greater than 2000 mg a.i./kg body weight in female Wistar rats.
