Brief description of classification related key information

Degradation

Biodegradation:              < 10% (OECD 301 B, CO2 evolution); read-across

Bioaccumulation

Expert statement:         Bioaccumulation is expected to be low.

Aquatic acute toxicity

For fish:              96 h, LC50 (Brachydanio rerio): 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 plant:              72 h, ErC50 (Scenedesmus subspicatus): No effects up to the limit of water solubility; read-across

Aquatic chronic toxicity

For fish:                                            28 d, NOEC (Brachydanio rerio): No effects up to the limit of water solubility; read-across

For aquatic invertebrates:         no data available

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, C18 unsaturated, trimers, hydrogenated is not considered to be rapidly degradable. However, the acute aquatic toxicity L(E)C50 values are above the water solubility limit for fish, invertebrates and algae. Therefore, the substance does not meet the criteria for classification and labelling as acute aquatic hazard according to the 2nd ATP of the Regulation (EC) No. 1272/2008 (CLP).

Valid chronic toxicity data are available for fish and algae - the lowest NOECs are above the water solubility limit. Therefore, Fatty acids, C18 unsaturated, trimers, hydrogenated does not meet the criteria for classification and labelling as chronic aquatic hazard according to the 2nd ATP of the Regulation (EC) No. 1272/2008 (CLP).

DSD:

The acute aquatic toxicity L(E)C50 values are above the water solubility of the substance (0.001 mg/L) limit for fish, invertebrates and algae. Therefore, Fatty acids, C18 unsaturated, trimers, hydrogenated does not meet the criteria for classification and labelling as environmental hazard according to Directive 67/548/EEC.
