Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Conclusion on classification

Based on available reliable data for toxicity of constituent category substance of LCAs, including 2-butyloctanol, short-term acute toxicity (LC50or EC50) to aquatic organisms is >0.01 mg/L and does not meet the definitive ecotoxicity criterion according to the ECHA guidance on PBT assessment (Part C). Chronic data on aquatic species are not available for 2-butyloctanol but are available for the structural analogue, but it is concluded that long-term effects are unlikely due to the ready biodegradability of 2-butyloctanol and therefore the criteria of Annex XIII REACH for aquatic toxicity are not fulfilled.

2 -butyloctanol is classified for the environment based on acute toxicity data for fish and invertebrates being below 1 mg/L. However, the substance is considered to be readily biodegradable and unlikely to bioaccumulate, resulting in classification of acute category 1.
