Results (fetuses)
- Fetal body weight changes:
- effects observed, non-treatment-related
- Description (incidence and severity):
- The mean weight of live male fetuses was decreased in low dose group (level 5 %): due to the lack of a dose response the effect was considered to be not treatment-related.

Applicant's summary and conclusion
- Conclusions:
- 2-Octyldodecan-1-ol is not cumulatively toxic to pregnant rats and does not reveal embryotoxic, fetotoxic or developmental toxic effects up to 1000 mg/kg bw, the highest dose tested.
- Executive summary:
According to an OECD 414 developmental toxicity study with 2 -octyl-1 -dodecanol, the test substance is not cumulatively toxic to pregnant CD rats and does not reveal embryotoxic, fetotoxic or developmental toxic effects up to 1000 mg/kg bw, the highest dose tested.
