Conclusion on classification
According to Article 13 of Regulation (EC) No. 1907/2006 "General Requirements for Generation of Information on Intrinsic Properties of substances", information on intrinsic properties of substances may be generated by means other than tests e.g. from information from structurally related substances (grouping or read-across), provided that conditions set out in Annex XI are met.
Annex XI, "General rules for adaptation of this standard testing regime set out in Annexes VII to X” states that “substances whose physicochemical, toxicological and ecotoxicological properties are likely to be similar or follow a regular pattern as a result of structural similarity may be considered as a group, or ‘category’ of substances. This avoids the need to test every substance for every endpoint”.
Since the group concept is applied to the members of the alkyl sulfates category, data will be generated from a representative category member to avoid unnecessary animal testing. Additionally, once the group concept is applied, substances will be classified and labeled on this basis.
Classification related key information:
Biodegradation in water: readily biodegradable (OECD 301 D)
Bioaccumulation: no potential; log Pow = 0.22 at 20 ºC (EU Method A.8)
Water solubility = 180 g/L at 20 ºC (EU Method A.6)
Acute toxicity key values of C9AS Na (CAS 1072-15-7):
- For fish: 96h LC50 (mortality) = 21 mg/L (nominal concentration, read-across from CAS 142-31-4 and CAS 142-87-0)
- For invertebrates: 48h EC50 (Daphnia magna, immobilization) > 100 mg/L (nominal concentration, read-across from CAS 142-31-4 and CAS 142-87-0)
- For algae: 72h EC50 (growth rate) = 17 mg/L (OECD 201, read-across from CAS 126-92-1 and CAS 142-87-0)
Chronic toxicity key values for of C9AS Na (CAS 1072-15-7):
- For fish: 42d NOEC (Pimephales promelas; mortality and growth) ≥ 1.357 mg/L (measured concentration, read-across from CAS 151-21-3)
- For invertebrates 21d NOEC (Daphnia magna, reproduction) = 1.4 mg/L (measured concentration, OECD 211, read-across from CAS 142-87-0)
- For algae: 72h EC10 (growth rate) = 1.8 mg/L (OECD 201, read-across from CAS 126-92-1 and CAS 142-87-0)
Classification justification according to CLP:
Based on the data above, C9AS Na (CAS 1072-15-7) 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 fish, invertebrates and algae – the lowest chronic values were recorded for fish (NOEC = 1.357 mg/L) and aquatic invertebrates (NOEC = 1.4 mg/L). C9AS Na (CAS 1072-15-7) does not need to be classified and labeled as environmental hazard according to Regulation (EC) No.1272/2008 (CLP) and Regulation (EU) No. 286/2011 (2nd ATP).
M-factor for acute aquatic toxicity: not need to be assigned
M-factor for chronic aquatic toxicity: not need to be assigned
Classification justification according to DSD:
Based on the data above, C9AS Na (CAS 1072-15-7) 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. C9AS Na (CAS 1072-15-7) does not need to be classified and labeled as environmental hazard according to Directive 67/548/EEC.
