Description of key information
The readily biodegradability of GLYCOLIERRAL was investigated according to OECD guideline 301 F and the inherent biodegradability according to OECD guideline 302C. No biodegradation was observed in either tests. Thus, Glycolierral should be regarded as not readily and not inherently biodegradable according to these tests.
The inherent biodegradability of GLYCOLIERRAL was investigated according with a method similar to OECD guideline 302 C and in accordance with GLP principles. It was concluded that GLYCOLIERRAL was not inherently biodegradable under the conditions of the Modified MITI Test (II). The study is considered to be reliable with restrictions since it is not possible to fully investigate the cause(s) for the "negative" biodegradation and the variation between duplicates based on the reported data. In addition, the concentration of test substance in the test solutions was not analytically determined, the substance was tested in duplicate, and a toxicity control was not included. However, a toxicity control was included in the ready biodegradability study (No. 02-E073) and no toxicity was reported at a test substance concentration of 100 mg/L. Despite these deficiencies, it is nonetheless concluded that GLYCOLIERRAL is not inherently biodegradable.
Key value for chemical safety assessment
- Biodegradation in water:
- under test conditions no biodegradation observed
Additional information
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.
