Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The assessment is based on the data currently available. New studies, based on the category review and the final decisions issued for some of the category substances, which are also relevant for this assessment, are currently being conducted. The hazard assessment with respect to aquatic toxicity will be updated once all ongoing studies have been finalised.

 

Classification related key information for:

Biodegradation in water: readily biodegradable

Bioaccumulation: low potential for bioaccumulation

Water solubility: > 330 g/L at 20 °C (OECD 105)

 

Acute toxicity:

- For fish: 96 h LC50 (Danio rerio) = 7.1 mg a.i./L (nominal, OECD 203)

- For invertebrates: 48 h EC50 (Daphnia magna, immobilization) = 91 mg a.i./L (nominal, OECD 202)

- For algae: 72 h ErC50 (Pseudokierchnerialla subspicata, growth rate) > 100 mg a.i./L (nominal, OECD 201)

 

Chronic toxicity:

- For invertebrates: 21 d NOEC (Daphnia magna, reproduction): = 5.3 mg a.i./L (measured, OECD 211)

- For algae: 72h NOErC (Pseudokierchneriella subspicata, growth rate) = 31.3 mg a.i./L (nominal, OECD 201)

 

Classification justification according to CLP

Based on the data above, AES (C9 -11, 1-2.5EO) NH4 is considered to be rapidly degradable and has a low potential for bioaccumulation. The acute aquatic toxicity L(E)C50 are above 1 mg/L for fish, invertebrates and algae. Valid chronic toxicity data are available to aquatic invertebrates and algae – the lowest NOEC is 5.3 mg/L (thus not in the range of > 0.1 to < 1 mg/L) for aquatic invertebrates. AES (C9 -11, 1 -2.5EO) Na (CAS 160901 -27 -9)  does not need to be classified and labeled as environmental hazard according to the Regulation (EC) No.1272/2008 (CLP) and the Regulation (EU) No. 286/2011 (2nd ATP).
