Conclusion on classification

Justification for classification

According to Article 13 "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 substance. This avoids the need to test every substance for every endpoint”.

Since the group concept is applied to the members of the SCAE C2-C8 category, data will be generated from representative category members to avoid unnecessary animal testing. Additionally, once the group concept is applied, substances will be classified and labelled on this basis.

 Brief description of the data relevant for classification

 

Degradation

Biodegradation: 80.8% of CO2 evolution (OECD 310)

Bioaccumulation

Expert statement: Bioaccumulation is expected to be low.

Aquatic acute toxicity

For fish: 96 h, LC50 (Cyprinus carpio): no effects up to the limit of water solubility; read-across

For aquatic invertebrates: 48 h, EC50 (Daphnia magna): no effects up to the limit of water solubility; read-across

For algae/aquatic plants: 72 h, ErC50 (Pseudokirchnerella subcapitata): no effects up to the limit of water solubility; read-across

Aquatic chronic toxicity

For fish: no data available

For aquatic invertebrates: 21 d, NOEC (Daphnia magna): no effects up to the limit of water solubility; read-across

For algae/aquatic plant: 72 h, NOErC (Scenedesmus subspicatus): no effects up to the limit of water solubility; read-across

Conclusion on classification

CLP:

Based on the data above, Fatty acids, essential, ethyl esters (CAS No. 91051-05-7) is considered to be readily biodegradable. The substance is poorly soluble in water, and no effects occurred up to its water solubility limit in acute tests with fish, algae and daphnia. Valid chronic toxicity data are available for daphnia and algae. No chronic effects were observed up to the limit of water solubility. Therefore, Fatty acids, essential, ethyl esters does not need to be classified and labelled as environmental hazard according to the 2^ndATP of the Regulation (EC) No.1272/2008 (CLP).

DSD:

The substance is poorly soluble in water, and no effects occurred up to its solubility limit in acute tests with for fish, algae and daphnia. Therefore, Fatty acids, essential, ethyl esters does not need to be classified and labelled as environmental hazard according to Directive 67/548/EEC.
