Additional information
Reproductive/Developmental toxicity screening test:
Key study. Study with 12 male/ 12 female rats at doses of 100, 300, 1000 mg/kg/day, according to OECD Test Guideline 422.
The result was as follows: fertility/reproductive toxicity NOAEL = 1000 mg/kg bw /day
Two-generation reproductive toxicity study:
In accordance with column 2 of REACH Annex IX, the two-generation reproductive toxicity study ( required in section 8.7.3) does not need to be conducted as the 28-day and 90-day study results do not indicate adverse effects on reproductive organs or tissues.
Short description of key information:
Fertility/ reproductive toxicity NOAEL= 1000 mg/kg bw , key study with 12 male/ 12 female rats, at doses of 100, 300, 1000 mg/kg/day, according to OECD Test Guideline 422.
Justification for selection of Effect on fertility via oral route:
Only one study available.
Effects on developmental toxicity
Description of key information
Developmental toxicity NOAEL= 1000 mg/kg bw , key study with 12 female rats, at doses of 100, 300, 1000 mg/kg/day, according to OECD Test Guideline 422.
Effect on developmental toxicity: via oral route
- Endpoint conclusion:
- no adverse effect observed
- Dose descriptor:
- NOAEL
- 1 000 mg/kg bw/day
- Study duration:
- subacute
- Species:
- rat
- Quality of whole database:
- The key study is GLP compliant and Klimisch score 1.
Additional information
Reproductive/Developmental toxicity screening test:
Key study. Study with 12 female rats at doses of 100, 300, 1000 mg/kg/day, according to OECD Test Guideline 422.
The result was as follows: developmental toxicity NOAEL = 1000 mg/kg bw /day
Pre-natal developmental toxicity study: The study does not need to be conducted since based on the available data from the reproduction/developmental toxicity screening test, the test material did not cause any adverse effects.
Justification for selection of Effect on developmental toxicity: via oral route:
Only one study available. See the attachment above.
Justification for classification or non-classification
Based on the available information:
fertility/reproductive toxicity NOAEL = 1000 mg/kg bw /day
developmental toxicity NOAEL = 1000 mg/kg bw /day
the substance is not classified.
