Description of key information
Additional information
The aquatic toxicity of EGDN was classified GHS-CLP Regulation with the following results:
EGDN does not classify as Acute Category 1[1]because the representative LC50 values for fish and EC50 values for daphnia (crustacean) and algae are not below 1 mg/L. (Classification criterion is EC50 or LC50 < 1 mg/L)
The representative chronic toxicity values for EGDN range from 0.03 to 3.23 mg/L (i.e., potentially triggering Chronic Category 1 and 2; Classification criteria are EC50 or LC50 < 1 mg/L for Category 1 and <10 mg/L for Category 2.). However, EGDN does not classify for Chronic (Long-term) Aquatic Hazard because the log Kow is less than 3, and, based on the combined QSAR modelling of biodegradation and read-across from biodegradation studies on nitroglycerine (refer to USEPA 2010), degradation is expected to be >70% in 28 days.

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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
