Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Aquatic toxicity studies with barium 3,5,5-trimetylhexanoate are not available.Read-across to the assessment entities soluble barium substances and trimethylhexanoic acid (and its structural analogue neodecanoic acid) is applied for the assessment of barium 3,5,5-trimethylhexanoate since the ions of barium 3,5,5-trimethylhexanoate determine its fate and toxicity in the environment. Based on measured total Ba-levels in the water column, a 96-h LC50 of > 97.5 mg Ba/L (corresponding to > 3.5 mg dissolved Ba/L) is reported for fish whereas the 96-h LL50 is > 100 mg/L neodecanoic acid (structural analogue of trimethylhexanoic acid) for O. mykiss. This is supported by QSAR-based estimations for trimethylhexanoic acid. According to the QSAR-based outcome of the model ECOSAR v.2.0, trimethylhexanoic acid has also a low potential for acute toxicity since the 48-h LC50 was estimated with 81.4 mg/L for freshwater fish.

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
