Description of key information

The substance is readily biodegradable.

Key value for chemical safety assessment

Additional information

One GLP guideline study according OECD 301 B on the biodegradability of the test substance is available. The degradation rate is 80 -90 % after 28 days. Octene, hydroformylation products, high-boiling are multi-component substrates and are typically characterized by different kinetic degradation steps.

Therefore the 10 days window is not applied and the test substance can be classified as „readily biodegradable“ if the required pass level of the test guideline OECD 301B (60% of ThCO2) was reached.

This evaluation is in accordance with the OECD Guidelines for the testing of chemicals, laid down in the revised introduction to the OECD Guidelines for testing of chemicals, section 3; Part 1, Principles and strategies related to the testing of degradation of organic compounds, adopted 23 March 2006.
