Readily biodegradable: 107% (BOD) in 28 days (OECD 301 F)
Two biodegradation studies are available for 2-amino-1,3-propanediol
(APD), one ready biodegradability study and one investigating
In the key study, ready biodegradability was tested following OECD
guideline 301 F and according to GLP (Hales, 2011). Activated sludge was
used as inoculum. By the end of the 28-day test period, biodegradation
reached 107.9%, based on BOD, or 82.5%, based on CO2 evolution. Over 60%
biodegradation was reached within the 10-day window.
The biodegradability of APD was also shown in the inherent
biodegradability study, conducted with activated sludge and according to
OECD guideline 302 C. Biodegradation reached 92.2% during the 22-day
Hence, APD can be considered readily biodegradable according to
