Description of key information
Tetrahydro Pseudoionone is considered to be readily biodegradable.
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
A reliable ready biodegradability study was performed in accordance with GLP and OECD Guideline 301F (Givaudan Suisse SA, 15 -E029). Tetrahydro Pseudoionone undergoes 75% biodegradation after 28 days under the test conditions. The 10-day window criterion is also fulfilled (20% biodegradation on day 3 and 60% on day 13). Thus, Tetrahydro Pseudoionone should be regarded as readily biodegradable.
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.
