Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information

The substance is considered to be readily biodegradable as demonstrated in the Closed Bottle Test.

The 10-day time window has been ignored as a pass/fail criterion. Moreover, the substance is a multi-constituent substance with structurally similar constituents which may pass the 10 day window criterion individually while that is not seen in the mixture and in the molecule a hydrophilic group is linked to a hydrophobic moiety. Biodegradation of both moieties of surfactants requires the concerted action of at least two microorganisms as a single organism usually lacks the full complement of enzymatic capabilities. The biodegradation of the two moieties of 1-propanamine, 3-(isodecyloxy)- may be fully in line with the 10-day window criterion when judged as separate chemicals whereas the sum of the biodegradation curves is not. The biodegradation curve of 1 -propanamine, 3-(isodecyloxy)- should therefore not be used to assess a 10-day window effect.
