Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Conclusion on classification

Justification for classification

Brief description of the data relevant for classification

Degradation

Biodegradation: not inherently biodegradable (OECD 302 C)

Bioaccumulation

Expert statement: Bioaccumulation is expected to be low

Aquatic acute toxicity

For fish: 48 h, LC50 (Leuciscus idus melanotus): 493 mg/L; read-across

For aquatic invertebrates: 48 h, EC50 (Daphnia magna): > 143 mg/L; read-across

For algae/aquatic plants: 96 h, EC50 (Pseudokirchnerella subcapitata): > 97.2 mg/L; read-across

Aquatic chronic toxicity

For fish: no data available

For aquatic invertebrates: 21 d, NOEC (Daphnia magna): 45.2 mg/L; read-across

For algae/aquatic plant: 72 h, NOEC (Pseudokirchneriella subcapitata): > 97.2 mg/L; read-across

Conclusion on classification

CLP:

Based on the data above, UMA 121 is not considered to be rapidly degradable. The acute aquatic toxicity L(E)C50 values are > 1 mg/L for fish, invertebrates and algae. Therefore, the substance does not meet the criteria for classification and labelling as acute aquatic hazard according to the 6th ATP of the Regulation (EC) No 1272/2008 (CLP).

Valid chronic toxicity data are available - the lowest NOEC is > 1 mg/L. Therefore, the substance does not meet the criteria for classification and labelling as long-term aquatic hazard according to the 6th ATP of the Regulation (EC) No 1272/2008 (CLP).

DSD:

The acute aquatic toxicity L(E)C50 values are > 10 mg/L for fish, invertebrates, and algae and a long-term NOEC > 1 mg/L was obtained with Daphnia magna. Therefore, UMA 121 does not meet the criteria for classification and labelling as environmental hazard according to Directive 67/548/EEC.
