Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

Based on ECOSAR v.1.11 (EPISUITE, 2012), the test substance, 3 -PPB, was predicted to have LC50 of 1.081 mg/l after 96 hours exposure to fish. In an acute fish toxicity study with benzyl benzoate (GLP compliant and to current guideline) the LC50 was determined to be 2.32 mg/l.

Based on the same computer program EPISUITE, the test substance, 3 -PPB, was predicted to have LC50 of 0.774 mg/l (baseline toxicity) after 48 hours exposure to Daphnid. In an acute aquatic toxicity study with benzyl benzoate, the LC50 was determined to be 4.8 mg/l.

In a new 21 -day chronic Daphnia magna study performed with benzyl benzoate, the NOEC and LOEC for reproduction was calculated to be 0.258 mg/L and 0.455 mg/L, respectively and the NOEC and LOEC for mortality was calculated to be ≥ 0.97 mg/L and > 0.97 mg/L, respectively.

The most sensitive species is algal according to the data from the benzoate chemical group. Therefore a new study with 3-phenyl propyl benzoate has been performed and the EC50growth rate and NOEC determined to be 0.30 and 0.14 mg/l, respectively.

The latter value is used in the environmental risk assessment.
