Endpoint summary
Administrative data
Key value for chemical safety assessment
Effects on fertility
Effect on fertility: via oral route
- Endpoint conclusion:
- no adverse effect observed
- Dose descriptor:
- NOAEL
- 1 000 mg/kg bw/day
- Study duration:
- subchronic
- Species:
- rat
- Quality of whole database:
- Klimisch 1
Effect on fertility: via inhalation route
- Endpoint conclusion:
- no study available
Effect on fertility: via dermal route
- Endpoint conclusion:
- no study available
Additional information
IMB is of low toxicity in acute toxicity in an acute oral study. A reproductive toxicity screening study is available for the closely related analogue, EMB, which showed no evidence of effects on fertility (NOAEL 1000mg/kg bw/day). Therefore, additional animal studies to investigate potential reproduction toxicity are not scientifically justified.
Effects on developmental toxicity
Description of key information
No effects seen.
Link to relevant study records
- Endpoint:
- developmental toxicity
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- other:
- Reason / purpose for cross-reference:
- read-across source

Ne effects observed
Additional information
IMB is of low toxicity in acute toxicity in an acute oral study. A reproductive toxicity screening study is available for the closely related analogue, EMB, which showed no evidence of effects on fertility (NOAEL 1000mg/kg bw/day). Therefore, additional animal studies to investigate potential reproduction toxicity are not scientifically justified.
Justification for classification or non-classification
A 54 day repeat dose study with reproductive / developmental toxicity screening with the read-across substance EMB showed no toxicity. IMB shows no toxicity in any other studies. Consequently this substance will not be classified as toxic to reproduction.
