Description of key information

The ready biodegradability of the test material was assessed in an OECD 301F Manometric Respirometry Test

Key value for chemical safety assessment

Biodegradation in water:
readily biodegradable

Additional information

2-Amino-2-methylpropanol meets the criteria of ready biodegradability in an OECD 301F Manometric Respirometry test, with 89% biodegradation in 28 days based on oxygen consumption at a test substance concentration of 11 mg/L. In a supporting study, an OECD 301F test using a higher concentration of test substance (100 mg/L) showed 45% degradation after 28 days based on oxygen consumption. In another supporting study, biodegradation of the test compound in an OECD 301D Closed Bottle Test reached 40% in 28 days.
