Additional information

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.
