Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Conclusion on Classification

Biodegradation: 37% after 28 d (ISO 14593)

Bioaccumulation: no potential for bioaccumulation

 

Aquatic acute toxicity

Fish: 96 h, LC50 (Oncorhynchus mykiss): 0.355 mg/L (nominal; OECD 203)

Aquatic invertebrates: 48 h, EC50 (Daphnia magna): 0.59 mg/L (nominal; OECD 202)

Aquatic algae: 72 h, EC50 (Desmodesmus subspicatus): 0.0087 mg/L (measured, geometric mean; OECD 201)

 

Aquatic chronic toxicity

Fish: 28 d, chronic value (fish): 0.012 - 0.039 mg/L (ECOSAR v1.00)

Aquatic invertebrates: 21 d, NOEC (Daphnia magna): 0.1 mg/L (meas. TWA; OECD 211)

Aquatic algae: 72 h, NOEC (Desmodesmus subspicatus): 0.0044 mg/L (measured, geometric mean; OECD 201)

 

Classification according to CLP

Based on the data above, Atmer 163 needs to be classified and labeled as environmental hazard Acute Cat. 1 according to the 2nd ATP of Regulation (EC) No. 1272/2008 (CLP) based on the EC50 (72 h) of 0.0087 mg/L for Desmodesmus subspicatus.
Atmer 163 is not considered to be rapidly degradable. Valid chronic data are available for aquatic invertebrates and algae. The lowest NOEC is 0.0044 mg/L for Desmodesmus subspicatus. Thus, the test substance needs to be classified and labeled as long-term aquatic Chronic Cat. 1 according to the 2ndATP of Regulation (EC) No. 1272/2008 (CLP).

M-factor for acute aquatic toxicity: 100
M-factor for chronic aquatic toxicity: 10

 

Classification according to DSD

Based on the data above, Atmer 163 is not considered to be rapidly degradable. The acute aquatic toxicity EC50 is 0.0087 mg/L (measured, geometric mean) for Desmodesmus subspicatus. Atmer 163 needs to be classified and labeled as environmental hazard R50/53 according to the Directive 67/548/EEC.
