Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

 

Readily biodegradable: (69% after 28 d, OECD 301D)

Low potential for bioaccumulation

Water solubility: 112.8 g/L at 20 ºC (OECD 105)

 

Toxicity to fish:

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

48 h LC50 (Leuciscus idus) = 4.3 mg/L a.i. (nominal, DIN 38412 part 15)

 

Toxicity to aquatic invertebrates:

48 h EC50 (Daphnia magna, immobilization) = 1.4 mg/L a.i. (nominal, OECD 202)

 

Toxicity to aquatic algae:

ErC50 (72h): 0.386 mg a.i./L (meas. geom. mean, OECD 201)

ErC10 (72h): 0.0985 mg a.i./L (meas. geom. mean, OECD 201)

 

Classification justification according to CLP

Based on the data above, AES (C16 -18 and C18-unsaturated, 1-2.5 EO) Na is considered to be rapidly degradable and has a low potential for bioaccumulation. The acute aquatic toxicity L(E)C50 is above 1 mg/L for fish, invertebrates and algae. Valid chronic toxicity data are available for algae – the ErC10 is 0.606 mg/L (thus in the range of > 0.1 to < 1 mg/L). AES (C16 -18 and C18-unsaturated, 1-2.5 EO) Na needs to be classified and labeled as environmental hazard Chronic Cat. 3 according to the Regulation (EC) No.1272/2008 (CLP) and the Regulation (EU) No. 286/2011 (7th ATP).
