Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The PNECs have been included in the REACH registration for completeness. No exposure assessment has been conducted as the substance is not present in concentrations which would lead to polymers being classified as hazardous under the CLP regulation.  No performance of the exposure assessmnet is further supported with 3 documents attached in Section 13.2 of this REACH registration.   

Conclusion on classification

No effects were observed at a concentration of 89.2 mg/L in Daphnia magna. As this is based on data provided by ECHA, full details on this value are not available although this is possibly the highest concentration tested. In Algae a 72 hr NOEC of 69.98 mg/L is provided, again with no indications why higher values were not tested. In an acute toxicity study to fish a 96 hr LC50 of 33.5 mg/L is available, which is the key value for safety assessment as fish appear to be the most sensitive trophic level. Based on this value, no classification in accordance with the CLP regulation (1272/2008, as amended) is relevant for this substance in relation to aquatic acute toxicity. When considering Chronic toxicity, the only available result is an algae study NOEC of 69.98 mg/L. As the substance is not readily biodegradable (not fulfilling 10 -day window criterion), consideration of the acute data is applicable in this case. As the lowest acute LC/EC50 value is > 10 and < 100 mg/L (fish), classification as Aquatic Chronic. 3 is deemed appropriate for this substance.
