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 analogue concept is applied to the secondary fatty amides, data will be generated from a representative member to avoid unnecessary animal testing. Additionally, once the analogue concept is applied, substances will be classified and labelled on this basis.

Classification justification according to CLP:

Based on the ecotoxicological data, (Z)-N-Octadec-9-enylhexadecan-1-amide (CAS No. 16260-09-6) does not pose a risk to organisms in regard to bioaccumulation; the substance is not readily biodegradable. Short term toxicity data of the substance itself and an analoque substance towards fish, daphnia and algae give a NOEC greater than the water solubility of (Z)-N-Octadec-9-enylhexadecan-1-amide (CAS No. 16260-09-6). No toxicity could be observed in any test. Therefore, no classification is required for (Z)-N-Octadec-9-enylhexadecan-1-amide (CAS No. 16260-09-6) 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 ecotoxicological data substances, (Z)-N-Octadec-9-enylhexadecan-1-amide (CAS No. 16260-09-6) does not pose a risk to organisms in regard to bioaccumulation; the substance is not readily biodegradable. The substance is poorly soluble in water and no effects occurred up to its solubility in acute tests for fish, algae and aquatic invertebrates. Therefore, no classification is required for (Z)-N-Octadec-9-enylhexadecan-1-amide (CAS No. 16260-09-6) according to or the Directive 67/548/EEC.
