Additional information

The chronic toxicity of the substances of the Alcohol Ethoxylates (AE) category to aquatic invertebrates was assessed in a weight of evidence (WoE) approach based on the grouping of substances (category approach). The WoE approach combines experimental data, available for selected substances within the 'linear' subgroup of the AE category, and data derived by AE substance specific QSAR calculations. A study according to OECD guideline 211 on the long chain substance Alcohols, C16-18 (even numbered), ethoxylated, < 2.5 EO (CAS No. 68439-49-6) is still ongoing. The results of the study will be included in the present QSAR calculation once the final study report is available. The outcome of this study is expected to have an impact in particular on the evaluation of the long-chain substances. Therefore, the current assessment of the chronic toxicity of the target substance Octadecan-1-ol, ethoxylated is considered preliminary and will be updated as soon as the final study report is available.
