Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The short-term LC50 or EC50 values were 0.8, 0.202 and 3.0 mg/l, for fish, daphnia and algae, respectively. The chronic toxicity value (NOEC) for Daphnia and fish are 0.0399 and 0.093 mg/l respectively. Based on the high aquatic toxicity of tertbutylphenyl diphenyl phosphate, R50 can be applied. Tertbutylphenyl diphenyl phosphate is readily biodegradable, and is expected to have a tendency to bioaccumulate with a log Kow > 3, consequently it is classified as R50/R53 according to Directive 67/548/EEC (Toxic to aquatic organisms, may cause long-term adverse effects in the aquatic environment).

According to Regulation 1272/2008/EC tertbutylphenyl diphenyl phosphate would be classified as hazardous to the aquatic environment Acute Category 1 (H400: very toxic to aquatic life) and Chronic Category 1 (H410: very toxic to aquatic life with long lasting effects) based on these data.
