Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The test material attained 63% degradation after 28 days. Although  test material failed to satisfy the 10-Day window , whereby 60% degradation must be attained within 10 days of the degradation exceeding 10%, the substance is a chemically modified UVCB and therefore the 10 -day window does not apply.

Key value for chemical safety assessment

Biodegradation in water:
readily biodegradable

Additional information

Biodegradation of fatty acids, tall oil, oligomeric reaction products with maleic anhydride and calcium magnesium zinc salts was assessed in a GLP-compliant study following OECD guideline 301B. After 28 days, the test item was degraded by 63% (Harlan Laboratories, 2010). Although the 10-day window criterion was not met this criterion is not relevant for UVCB substances and therefore this substance is considered to be readily biodegradable.
