Applicant's summary and conclusion
- Conclusions:
- The acute toxicity of the target substance to aquatic invertebrates was assessed by read-across to other short-chain substances within the 'linear' subgroup of the Alcohol Ethoxylates (AE) category. Based on the read-across a EC50(48 h) of 40 mg/L is assumed for the target substance.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
