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 SCAE Me 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 labelled on this basis.

Classification related key information

Biodegradation in water: screening tests:

78% biodegradation in 28 days (read-across) (OECD 301C)                                                                        

83% biodegradation in 28 days (read-across) (BODIS Test)

Bioaccumulation:                       

No significant bioaccumulation in biota is expected for this substance (see IUCLID section 5.3).

Acute toxicity:

-         Fish: LC50 (96 h) > 0.52 mg/L for Oryzias latipes (read-across)(OECD 203)

-         Aquatic invertebrates: EL50 (7d) > 100 mg/L for Daphnia magna (OECD 211)

-         Algae: EL50 (72 h) > 100 mg/L for Desmodesmus subspicatus (OECD 201)

 

Chronic toxicity:

-         Aquatic invertebrates: NOELR (21 d) >= 100 mg/L for Daphnia magna (OECD 211)

-         Algae: EL10 (72 h) > 100 mg/L for Desmodesmus subspicatus (OECD 201)

 

Non-Classification justification according to CLP

Fatty acids, C12 -14 (even numbered), methyl ester (CAS No. 308065-15-8) is considered to be rapidly degradable. Valid acute and chronic toxicity data showed to be > 1 mg/L. Fatty acids, C12 -14 (even numbered), methyl ester does not need to be classified and labelled as environmental hazard according to the 2nd ATP of the Regulation (EC) No.1272/2008 (CLP).

Non-Classification justification according to DSD

Based on the data above, Fatty acids, C12 -14 (even numbered), methyl ester (CAS No. 308065-15-8) is rapidly degradable and is considered to have a low potential for accumulation. The acute aquatic toxicity L(E)C50 is > 1 mg/L in water for fish, algae and daphnia. Therefore, Fatty acids, C12 -14 (even numbered), methyl ester does not need to be classified and labelled as environmental hazard according to Directive 67/548/EEC.
