Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

TXIB is not acutely toxic at the limit of water solubility (saturation). However, a NOEC in a long-term study (Daphnia magna) was observed in the range of 0.1 to ≤ 1.0 mg/L. The experimental BCF is < 500. The substance achieved > 60% degradation based upon CO2 evolution in a ready biodegradtion study (OECD 301B) but failed to meet the 10-day window criterion. This is likley caused by the intial test substance being greater than the water solubility of the substance. However, as the substance exhibited greater than 70% biodegradation in the 28 day study the substance is considered to be rapidly biodegradable. Based upon the long-term NOEC in the range of 0.1 to ≤ 1.0 mg/L and the substance being considered rapidly biodegradable, the substance has been classified as Chronic Category 3 under the CLP.
