CLASS METHOD (if applicable):
- Rationale for the selection of the starting dose: Available information indicated that the test item is likely to be non-toxic with regard to acute toxicity. Hence, the limit dose of 2000 mg/kg body weight was used as a starting dose. - Doses:
- 2000 mg/kg bw
- No. of animals per sex per dose:
- 6 females
- Control animals:
- no
- Details on study design:
- - Duration of observation period following administration: 14 days
- Frequency of observations: immediately after dosing, 0.5, 1, 2 and 4 h after administration
- Frequency of weighing: immediately prior to dosing and weekly thereafter
- Necropsy of survivors performed: yes
- Other examinations performed: clinical signs, body weight, gross necropsy

- Based on:
- test mat.
- Remarks on result:
- other: LD50 is cut-off according to OECD 423
- Mortality:
- All (6/6 females) animals survived the limit dose of 2000 mg/kg body weight.
- Clinical signs:
- During the observation period, no animals displayed signs of intoxication, change of health, or any other adverse reaction.
- Body weight:
- The body weight of all animals increased during the study. No body weight losses were observed between the first and second week after administration.
- Gross pathology:
- During necropsy, no macroscopic findings were observed.

Applicant's summary and conclusion
- Interpretation of results:
- other: CLP/EU GHS criteria not met, no classification required according to Regulation (EC) No. 1272/2008.
- Conclusions:
- The LD50 of the test item has been determined to be greater than 2000 mg/kg body weight after single oral administration to female Wistar rats.
Based on 'Annex 2d Test Procedure with a Starting Dose of 2000 mg/kg body weight' of OECD 423 it can also be concluded that the LD50 cut-off value is equal to or greater than 5000 mg/kg body weight after single oral administration to Wistar rats.
