Description of key information
The test substance was assessed for biodegradability according to OECD guideline 301F. The test substance was readily biodegradable.
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
The ready biodegradability of Aldehyde C12 Lauric has been determined by the Respirometric Method (modified MITI Test I) according to the OECD Guidelines for Testing of Chemicals, Method No. 301F.
In the conditions of the test, Aldehyde C12 Lauric undergoes 73% biodegradation after 28 days. The biodegradation rate reached after the 10-day window is 59%, which is just below the pass criterion of 60%. However, the shape of the degradation curve, which shows immediate oxygen consumption followed by a gradual increase, indicates that the curve is influenced by processes such as abiotic degradation and/or dissolution rates (water solubility of aldehyde C12 Lauric is only 1.6mg/L). As the curve recorded is not purely the result of biodegradation kinetics, the 10 day window criterion cannot be assessed and should not be applied to interpret the results of the test. Thus, Aldehyde C12 Lauric should be regarded as readily biodegradable according to this test based only on the biodegradation percentage of 73% at day 28.
At the concentration used in the test (100 mg/L), Aldehyde C12 Lauric is not inhibitory to the micro-organisms.
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.
