Applicant's summary and conclusion
- Executive summary:
A reliable QSAR model estimates that the 30 day NOEC for fish (chronic toxicity) will be 11482mg/l. The model also indicates that with increasing numbers of ethylene oxide units in the molecule, the toxicity further decreases.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
