Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information

 The following ecotoxicological values are available:


acute fish:                                  EC50 > 0.0013 mg/L from supporting study, no effects within water solubility

chronic fish:                            NOEC 10 mg/L , OECD 210

acute daphnia:                             EC50: > 100 mg/L, OECD 202

chronic daphnia:                          ELR10 reproduction 21d: 4.12 mg/L nominal loading rate (WAF); ELR50 reproduction 21d: > 10 mg/L nominal loading rate (WAF), OECD 211

acute algae:                               ErLR50 72h > 100mg/L nominal loading rate (WAF) , OECD 201

chronic algae:                             ErLR10 72h > 100mg/L nominal loading rate (WAF) , OECD 201


In addition: Data for the constituent Monoalkylated DPA with the hightest bioaccumulation potential in the PBT assessment:


acute fish:                    NOEC and LC50 were > 0.013 mg/l (nominal) and > 0.0013 mg/L   (mean measured), OECD 203 , no mortality in the range up to the water solubility

acute daphnia:            NOEC and EC50 were > 0.013 mg/l (nominal) and > 0.0014 mg/L (mean measured), OECD 202, no mortality in the range up to the water solubility

algae:                           NOEC and EC50 were > 0.013 mg/l (nominal) and > 0.00222 mg/L (mean measured), OECD 201, no effects in the range up to the water solubility.

Additional information

No inhibitory or toxic effects of the UVCB substance was determined by toxicity tests on aquatic invertebrates (acute) and algae, respectively. No adverse effects in a fish early life-stage test were observed. Only in a long-term toxicity test to Daphnia adverse effects were observed > 1mg/L. Thus, the substance is with high probability acutely not harmful to aquatic organisms. The PNECs are therefore based on the results of the available aquatic toxicity tests.
