Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information

In the test according to OECD 301B, some biodegradation was observed, although not sufficient to classify as 'readily biodegradable'.
Based on experience and available test results, the substance is classified as 'inherently biodegradabe'.

Key value for chemical safety assessment

Biodegradation in water:
inherently biodegradable, not fulfilling specific criteria

Additional information

From the attached GPC analyses, it becomes clear that approximately 50% of the substance consists of unreacted natural triglycerides.

Natural triglycerides are known to be biodegradable from literature [1, 2].

The test in OECD 301B is highly dependent on the solubility of the substance for the substance to reach the inoculum.

It is assumed that the biodegradatin rate is limited by the low solubility of the test substance. The solubility of the test substances is low and could not be determined experimentally.

Based in these observations the substance is classified as 'inherently biodegradable'.
