Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Conclusion on classification

Biodegradation: not readily biodegradable: 95% in 28 d (OECD 301B)

 

Bioaccumulation: The substance has a low potential for bioaccumulation (log Pow < 3).

Aquatic short-term toxicity

96h, LC50 for Pimephales promelas: 29 mg/L (OECD 203); for Cyprinodon variegatus: 4.1 mg/L (ASTM E-35 1980)

48h, EC50 for Ceriodaphnia dubia: 5.55 mg/L (OECD 202); for Artemia salina: 3.15 mg/L (acute toxicity test)

72h, EC50 (Desmodesmus subspicatus): > 120 mg/L (DIN 38412, part 9)

 

Aquatic long-term toxicity

42d, NOEC for Pimephales promelas: >= 1.36 mg/L (42d flow-through test)

7d, NOEC for Ceriodaphnia dubia: 0.88 mg/L (EPA-600/489/001)

72h, NOEC for Desmodesmus subspicatus: 30 mg/L (DIN 38412, part 9)

 

Classification justification according to CLP:

Based on the available data, C12AS Na (CAS 151-21-3) is considered to be rapidly degradable and has 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 fish, invertebrates and algae – the lowest NOEC is 0.88 mg/L (thus in the rage of > 0.1 to < 1 mg/L) for aquatic invertebrates. C12AS Na (CAS 151-21-3) 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 (2nd ATP).

 

Classification justification according to DSD:

Based on the available data, C12AS Na (CAS 151-21-3) is considered to be rapidly degradable and has a low potential for bioaccumulation. The acute aquatic toxicity L(E)C50 values are above 1 mg/L for fish, invertebrates and algae. C12AS Na (CAS 151-21-3) does not need to be classified and labeled as environmental hazard according to Directive 67/548/EEC.
