Additional information
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”.
Classification related key information
Readily biodegradable: 70.8 – 75.7% in 28 days (OECD 301B); read across
Acute aquatic toxicity freshwater:
- Fish: LC50 (96 h): 2.6 mg a.i./L (measured, arithm. mean)
- Aquatic invertebrates: LC50 (48 h): 2.7 mg a.i./L (nominal); read across
- Algae: ErC50 (72 h): 3.57 mg a.i./L (measured, arithm. mean); read across
Chronic aquatic toxicity:
- Fish: NOEC (21 d): 0.036 mg a.i./L (measured, arithm. mean); read across
- Aquatic invertebrates: NOEC (21 d): 0.006 mg a.i./L (measured, geom. mean); read across
- Aquatic algae: NOErC (72 h): 0.468 mg a.i./L (measured, arithm. mean); read across
Conclusion on classification
Sodium 2-biphenylate (CAS 132-27-4) is readily biodegradable. The acute aquatic toxicity L(E)C50 values are > 1 mg a.i./L for fish, aquatic invertebrates and algae. The chronic effect concentration is < 1 mg/L (NOEC (21 d): 0.006 mg a.i./L). Based on the available dataset the substance is classified as Aquatic Chronic 1 according to the consolidated version of Regulation (EC) No. 1272/2008 (CLP) considering all further amendments. The substance Sodium 2-biphenylate (CAS 132-27-4) is listed on Annex VI (Index No.604-021-00-1)to CLP (in force from 1 March 2018). The harmonised classification and labelling is Acute Cat. 1 according to Annex VI to CLP. Therefore the self-classification is Acute Cat. 1 and Chronic Cat. 1 according to the consolidated version of Regulation (EC) No. 1272/2008 (CLP) considering all further amendments and Annex VI to CLP.
M-factor for chronic aquatic toxicity: 1
