Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Classification related key information

Log Kow:           3.72 (EU method A.8)

Water solubility: 264 mg/L (EU method A.6)

Biodegradation:  79 -82 % in 28 days (OECD 301B): readily biodegradable

BCF:                  WoE approach: not bioaccumulative 

 

Aquatic acute toxicity:

For fish: LC50 (96h) = 17.8 mg/L (OECD 203)

For algae: EC50 (72h) = 14.3 mg/L (OECD 201)

For crustacea: EC50 (48h) = 24.0 mg/L (OECD 202)

 

Aquatic chronic toxicity:

For fish: NOEC(28d): no data

For algae: EC10(72h) = 10.4 mg/L (OECD 201)

For crustacea: NOEC(21d): no data

 

Classification according to CLP

Based on the data above, Triisobutyl phosphate (CAS 126-71-6, TiBP) is readily biodegradable. Acute aquatic toxicity is observed to be in the range of 10-100 mg/L. Valid chronic data are not available. Therefore, TiBP does not need to be classified and labelled for the environment according to the 2nd ATP of the Regulation (EC) No. 1272/2008 (CLP).
